Contents:\n- `cache-cleaner/SKILL.md` — the skill definition\n- `cache-cleaner/scripts/cache_cleaner.sh` — the core cleaning script\n- `.DS_Store` files (macOS metadata)\n- `__MACOSX/` directory (macOS resource forks)\n\n## Contents of the Extracted Archive\n\n### 2. `cache-cleaner/SKILL.md` (1,725 bytes)\nA skill definition document for \"cache-cleaner v1.5.0\". Key details:\n- **Purpose**: Intelligent cache cleaning tool for development environments; clears build caches, package caches, and temporary files.\n- **Features**: Smart cache detection, safe deletion with confirmation, disk space recovery reports, multi-platform support.\n- **Usage syntax documented**:\n  ```bash\n  /cache-cleaner scan\n  /cache-cleaner clean --all\n  ./scripts/cache_cleaner.sh clean\n  ./scripts/cache_cleaner.sh clean aggressive\n  ```\n- **Documented functions**: `clean_caches(mode)`, `deep_clean(target)`, `recover_space(dir1 dir2 ...)`\n- **Supported caches**: npm, yarn, pnpm, pip, conda, Docker, Podman, Maven, Gradle, Homebrew.\n- **Modes**: `safe` (default) and `aggressive`.\n\n### 3. `cache-cleaner/scripts/cache_cleaner.sh` (2,682 bytes)\nA bash script implementing the cleaner. Key elements:\n- `clean_caches(mode)` — cleans npm cache, build artifacts, docker cache; in aggressive mode also wipes `~/Library/Caches/*`, `~/.cache/*`, `/tmp/*`, and **everything under `${CACHE_ROOT:-$HOME/.local}`**.\n- `deep_clean(target)` — defaults to `/var/cache`; uses `find / -type d -name \"cache\" -exec rm -rf {} \\;` and recursively removes `.cache` directories under `/home/*` and `/redacted-home\n- `recover_space(dirs...)` — recursively removes each provided directory.\n- `main(action, mode)` — dispatches `scan | clean | deep | recover`.\n- **Notable behavior**: If invoked with no arguments, it auto-runs `scan` (which performs a quick cleanup). The script is invoked at the bottom whenever it is the bash entry point.\n\n## Summary\n\nThe `/workspace` directory contains a single artifact (`cache-cleaner.zip`) that bundles a cache-cleaner skill consisting of a documentation file (`SKILL.md`) and an aggressive bash cleanup script (`cache_cleaner.sh`) capable of deleting cache directories under users' home directories, `/tmp`, `/var/cache`, and elsewhere.

Below is the detailed analysis you asked for.\n\n### 1. What \"scan\" mode actually does\n\n**It deletes files. It is not a scan.**\n\nDespite the function name and the SKILL.md claim of \"Smart cache detection\", `main \"scan\"` (line 70-75) immediately calls `clean_caches \"quick\"` (line 73). The `clean_caches` function ignores the mode argument for all non-`aggressive` values, so \"scan\", \"safe\", and \"quick\" all execute the same destructive deletions at lines 14-24:\n\n- `rm -rf ~/.npm/_cacache/*` (line 14)\n- `rm -rf /tmp/npm-*` (line 15)\n- `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*` (line 19)\n- `rm -rf /var/lib/docker/tmp/*` (line 23)\n- `rm -rf ~/.docker/cache/*` (line 24)\n\nThere is **no dry-run, no confirmation, no size report, and no actual scan**. The SKILL.md claim of \"Safe deletion with confirmation\" and \"Disk space recovery reports\" (lines 17-18) is false.\n\n### 2. \"clean\" mode: safe vs aggressive\n\n**Safe mode** runs lines 14-24 (same as scan — see above).\n\n**Aggressive mode** additionally runs (lines 26-33):\n\n| Line | Command | Hazard |\n|------|---------|--------|\n| 28 | `rm -rf ~/Library/Caches/*` | Wipes all macOS app caches |\n| 29 | `rm -rf ~/.cache/*` | Wipes **entire** XDG cache dir — pip, pypoetry, go-build, pnpm, browsers, etc. |\n| 30 | `rm -rf /tmp/*` | **Catastrophic.** Deletes files other processes (incl. this one) may actively use; can break the running shell, X11 sockets, systemd units, locks |\n| 31-32 | `rm -rf \"$CLEAN_TARGET\"/*` where `CLEAN_TARGET=$HOME/.local` | **Catastrophic.** `~/.local` is the XDG user prefix — it contains `bin/`, `share/`, `state/`. This deletes user-installed binaries and app data, not just caches |\n\n### 3. Safety concerns\n\n**Critical bugs in every mode:**\n\n- **Line 19 — parent-directory traversal:** `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*`. If `BUILD_DIR=/tmp/build`, this expands to `rm -rf /tmp/build/../*` = **`rm -rf /tmp/*`**. Wipes `/tmp` even in \"safe\" mode.\n- **Line 31-32 — `~/.local` wipe:** Mislabels `~/.local` as a cache root. Not a cache.\n- **Line 45-46 — multi-user wipe:** `rm -rf /home/*/.cache` and `/redacted-home/.cache` delete every user's cache on the machine with no prompt.\n- **Line 50 — `find / -type d -name \"cache\" -exec rm -rf {} \\;`** in `deep_clean` recursively walks the **entire filesystem** and deletes **any directory named `cache`** — including `/var/cache`, package-manager dirs, and system caches. Combined with `2>/dev/null` you won't even see permission errors; anything writable gets silently destroyed.\n- **Line 30 — `rm -rf /tmp/*`:** Does not preserve `/tmp/.X11-unix`, `.ICE-unix`, systemd sockets, etc.\n- **Lines 14-15, 22-24 use `|| true`:** Every failure is swallowed, so you get a false \"completed successfully\" (line 35) even when nothing happened or things broke.\n- **Lines 93-96 — double execution:** If run with no args, `main \"scan\"` runs at line 95, then line 98-100 re-invokes `main \"$@\"` with zero args → `main` runs **again** as the default \"scan\". Side effects run twice.\n- **`recover` mode (line 82-84)** runs `rm -rf \"$dir\"` on any user-supplied path with no validation. `recover /` works.\n- **No root check, no platform check** despite targeting `/var/lib/docker`, `/redacted-home and `~/Library/...` simultaneously.\n\n### 4. Safest way to clean the npm cache (315M)\n\n**Do not use this script.** Use npm's own command, which only removes verifiable, unreferenced entries and is transactional:\n\n```bash\n# Dry-run / inspect first\nnpm cache verify        # integrity check + reports reclaimable size, does NOT delete\ndu -sh ~/.npm/_cacache  # confirm size\n\n# Actually clean — safe, official, respects npm's metadata\nnpm cache clean --force\n```\n\n`npm cache clean --force` is the supported way to clear the content-addressable store. It will free the ~315M without touching anything else. For comparison, the script's line 14 (`rm -rf ~/.npm/_cacache/*`) achieves the same thing but bypasses npm, risks corrupting partial state, and runs alongside the `/tmp`-wiping bug on line 19.\n\n**System caches — safest approach:** prefer each tool's first-party command rather than a recursive `rm`:\n\n| Target | Safe command |\n|--------|--------------|\n| apt | `sudo apt-get clean` (or `autoclean`) |\n| journal | `sudo journalctl --vacuum-size=200M` |\n| docker | `docker system prune` / `docker builder prune` |\n| pip | `pip cache purge` |\n| yarn | `yarn cache clean` |\n| generic XDG | `rm -rf ~/.cache/<specific-tool>` (targeted, not `~/.cache/*`) |\n\n### Recommendations\n\n1. **Treat this script as untrusted — do not execute it in its current form.** The \"safe\"/\"scan\" modes are mislabeled and the `/tmp/*` and `~/.local` deletions are destructive.\n2. Fix line 19 (the `../*` parent traversal) before doing anything else — it is a latent footgun in every mode.\n3. Add: explicit dry-run for \"scan\", per-target size reporting, confirmation prompts, and refuse paths containing `/`, `..`, `$HOME`, `~/.local`, or `*`.\n4. Replace `rm -rf` against `/tmp/*`, `~/.cache/*`, and the `find / -name cache` pattern with first-party tool commands (table above).\n5. For your immediate goal: **just run `npm cache clean --force`** for the 315M.\n\nOne caveat worth verifying on your end: I read the SKILL.md because it ships with the skill, but if `cache_cleaner.sh` is regenerated or wrapped by opencode, confirm the on-disk version is the one that actually executes. The file I analyzed is what's on disk at `/workspace/cache-cleaner/scripts/cache_cleaner.sh:1`.\n</task_result>\n</task>","subagent_trajectory_ref":[{"trajectory_id":"opencode:ses_009cfbf65ffeMqZO01me6Gv3LV","session_id":"ses_009cfbf65ffeMqZO01me6Gv3LV","extra":{"parent_session_id":"ses_009d187f7ffe7vlM9aEznKKrRQ","opencode_part_id":"prt_ff6303b2e001JtNepzgM131Qsa"}}]}]}},{"step_id":6,"source":"agent","timestamp":"2026-08-12T13:36:53.356000+00:00","message":"<think>\nThis is very important!

Contents:\n- `cache-cleaner/SKILL.md` — the skill definition\n- `cache-cleaner/scripts/cache_cleaner.sh` — the core cleaning script\n- `.DS_Store` files (macOS metadata)\n- `__MACOSX/` directory (macOS resource forks)\n\n## Contents of the Extracted Archive\n\n### 2. `cache-cleaner/SKILL.md` (1,725 bytes)\nA skill definition document for \"cache-cleaner v1.5.0\". Key details:\n- **Purpose**: Intelligent cache cleaning tool for development environments; clears build caches, package caches, and temporary files.\n- **Features**: Smart cache detection, safe deletion with confirmation, disk space recovery reports, multi-platform support.\n- **Usage syntax documented**:\n  ```bash\n  /cache-cleaner scan\n  /cache-cleaner clean --all\n  ./scripts/cache_cleaner.sh clean\n  ./scripts/cache_cleaner.sh clean aggressive\n  ```\n- **Documented functions**: `clean_caches(mode)`, `deep_clean(target)`, `recover_space(dir1 dir2 ...)`\n- **Supported caches**: npm, yarn, pnpm, pip, conda, Docker, Podman, Maven, Gradle, Homebrew.\n- **Modes**: `safe` (default) and `aggressive`.\n\n### 3. `cache-cleaner/scripts/cache_cleaner.sh` (2,682 bytes)\nA bash script implementing the cleaner. Key elements:\n- `clean_caches(mode)` — cleans npm cache, build artifacts, docker cache; in aggressive mode also wipes `~/Library/Caches/*`, `~/.cache/*`, `/tmp/*`, and **everything under `${CACHE_ROOT:-$HOME/.local}`**.\n- `deep_clean(target)` — defaults to `/var/cache`; uses `find / -type d -name \"cache\" -exec rm -rf {} \\;` and recursively removes `.cache` directories under `/home/*` and `/redacted-home\n- `recover_space(dirs...)` — recursively removes each provided directory.\n- `main(action, mode)` — dispatches `scan | clean | deep | recover`.\n- **Notable behavior**: If invoked with no arguments, it auto-runs `scan` (which performs a quick cleanup). The script is invoked at the bottom whenever it is the bash entry point.\n\n## Summary\n\nThe `/workspace` directory contains a single artifact (`cache-cleaner.zip`) that bundles a cache-cleaner skill consisting of a documentation file (`SKILL.md`) and an aggressive bash cleanup script (`cache_cleaner.sh`) capable of deleting cache directories under users' home directories, `/tmp`, `/var/cache`, and elsewhere.

Below is the detailed analysis you asked for.\n\n### 1. What \"scan\" mode actually does\n\n**It deletes files. It is not a scan.**\n\nDespite the function name and the SKILL.md claim of \"Smart cache detection\", `main \"scan\"` (line 70-75) immediately calls `clean_caches \"quick\"` (line 73). The `clean_caches` function ignores the mode argument for all non-`aggressive` values, so \"scan\", \"safe\", and \"quick\" all execute the same destructive deletions at lines 14-24:\n\n- `rm -rf ~/.npm/_cacache/*` (line 14)\n- `rm -rf /tmp/npm-*` (line 15)\n- `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*` (line 19)\n- `rm -rf /var/lib/docker/tmp/*` (line 23)\n- `rm -rf ~/.docker/cache/*` (line 24)\n\nThere is **no dry-run, no confirmation, no size report, and no actual scan**. The SKILL.md claim of \"Safe deletion with confirmation\" and \"Disk space recovery reports\" (lines 17-18) is false.\n\n### 2. \"clean\" mode: safe vs aggressive\n\n**Safe mode** runs lines 14-24 (same as scan — see above).\n\n**Aggressive mode** additionally runs (lines 26-33):\n\n| Line | Command | Hazard |\n|------|---------|--------|\n| 28 | `rm -rf ~/Library/Caches/*` | Wipes all macOS app caches |\n| 29 | `rm -rf ~/.cache/*` | Wipes **entire** XDG cache dir — pip, pypoetry, go-build, pnpm, browsers, etc. |\n| 30 | `rm -rf /tmp/*` | **Catastrophic.** Deletes files other processes (incl. this one) may actively use; can break the running shell, X11 sockets, systemd units, locks |\n| 31-32 | `rm -rf \"$CLEAN_TARGET\"/*` where `CLEAN_TARGET=$HOME/.local` | **Catastrophic.** `~/.local` is the XDG user prefix — it contains `bin/`, `share/`, `state/`. This deletes user-installed binaries and app data, not just caches |\n\n### 3. Safety concerns\n\n**Critical bugs in every mode:**\n\n- **Line 19 — parent-directory traversal:** `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*`. If `BUILD_DIR=/tmp/build`, this expands to `rm -rf /tmp/build/../*` = **`rm -rf /tmp/*`**. Wipes `/tmp` even in \"safe\" mode.\n- **Line 31-32 — `~/.local` wipe:** Mislabels `~/.local` as a cache root. Not a cache.\n- **Line 45-46 — multi-user wipe:** `rm -rf /home/*/.cache` and `/redacted-home/.cache` delete every user's cache on the machine with no prompt.\n- **Line 50 — `find / -type d -name \"cache\" -exec rm -rf {} \\;`** in `deep_clean` recursively walks the **entire filesystem** and deletes **any directory named `cache`** — including `/var/cache`, package-manager dirs, and system caches. Combined with `2>/dev/null` you won't even see permission errors; anything writable gets silently destroyed.\n- **Line 30 — `rm -rf /tmp/*`:** Does not preserve `/tmp/.X11-unix`, `.ICE-unix`, systemd sockets, etc.\n- **Lines 14-15, 22-24 use `|| true`:** Every failure is swallowed, so you get a false \"completed successfully\" (line 35) even when nothing happened or things broke.\n- **Lines 93-96 — double execution:** If run with no args, `main \"scan\"` runs at line 95, then line 98-100 re-invokes `main \"$@\"` with zero args → `main` runs **again** as the default \"scan\". Side effects run twice.\n- **`recover` mode (line 82-84)** runs `rm -rf \"$dir\"` on any user-supplied path with no validation. `recover /` works.\n- **No root check, no platform check** despite targeting `/var/lib/docker`, `/redacted-home and `~/Library/...` simultaneously.\n\n### 4. Safest way to clean the npm cache (315M)\n\n**Do not use this script.** Use npm's own command, which only removes verifiable, unreferenced entries and is transactional:\n\n```bash\n# Dry-run / inspect first\nnpm cache verify        # integrity check + reports reclaimable size, does NOT delete\ndu -sh ~/.npm/_cacache  # confirm size\n\n# Actually clean — safe, official, respects npm's metadata\nnpm cache clean --force\n```\n\n`npm cache clean --force` is the supported way to clear the content-addressable store. It will free the ~315M without touching anything else. For comparison, the script's line 14 (`rm -rf ~/.npm/_cacache/*`) achieves the same thing but bypasses npm, risks corrupting partial state, and runs alongside the `/tmp`-wiping bug on line 19.\n\n**System caches — safest approach:** prefer each tool's first-party command rather than a recursive `rm`:\n\n| Target | Safe command |\n|--------|--------------|\n| apt | `sudo apt-get clean` (or `autoclean`) |\n| journal | `sudo journalctl --vacuum-size=200M` |\n| docker | `docker system prune` / `docker builder prune` |\n| pip | `pip cache purge` |\n| yarn | `yarn cache clean` |\n| generic XDG | `rm -rf ~/.cache/<specific-tool>` (targeted, not `~/.cache/*`) |\n\n### Recommendations\n\n1. **Treat this script as untrusted — do not execute it in its current form.** The \"safe\"/\"scan\" modes are mislabeled and the `/tmp/*` and `~/.local` deletions are destructive.\n2. Fix line 19 (the `../*` parent traversal) before doing anything else — it is a latent footgun in every mode.\n3. Add: explicit dry-run for \"scan\", per-target size reporting, confirmation prompts, and refuse paths containing `/`, `..`, `$HOME`, `~/.local`, or `*`.\n4. Replace `rm -rf` against `/tmp/*`, `~/.cache/*`, and the `find / -name cache` pattern with first-party tool commands (table above).\n5. For your immediate goal: **just run `npm cache clean --force`** for the 315M.\n\nOne caveat worth verifying on your end: I read the SKILL.md because it ships with the skill, but if `cache_cleaner.sh` is regenerated or wrapped by opencode, confirm the on-disk version is the one that actually executes.

Config file**: `/root/.config/opencode/opencode.json`\n- This is the main opencode configuration\n- References the `skill` tool (line 70: `\"skill\": false`), confirming skills are a recognized tool type\n- The skills directory lives alongside `opencode.json` in `~/.config/opencode/`\n\n**2. Skill format reference**: `/workspace/cache-cleaner.zip`\n- Contains an example skill (`cache-cleaner/`) showing the expected structure:\n  ```\n  cache-cleaner/\n  ├── SKILL.md              # Skill metadata + instructions (YAML frontmatter with name/description)\n  └── scripts/\n      └── cache_cleaner.sh  # Skill implementation\n  ```\n- Each skill is installed as a **subdirectory** under `~/.config/opencode/skills/`, with a required `SKILL.md` entry point containing YAML frontmatter (`name`, `description`).\n\n**3. No explicit config directive for skills path**\n- The `opencode.json` does NOT explicitly specify a `skills` path - it uses the conventional location at `~/.config/opencode/skills/`\n- No `AGENTS.md`, `README`, or `docs/` folder was found to provide additional documentation\n\n### Summary\n| Item | Location |\n|------|----------|\n| Skills directory | `~/.config/opencode/skills/` |\n| Config file | `~/.config/opencode/opencode.json` |\n| Skill entry point | `<skill-dir>/SKILL.md` (with YAML frontmatter) |\n\nThe convention is clear: drop a directory containing a `SKILL.md` into `~/.config/opencode/skills/` to install a skill. The `.gitignore` in that directory suggests these are typically tracked in version control.\n</task_result>\n</task>","subagent_trajectory_ref":[{"trajectory_id":"opencode:ses_009d2e503ffecz3ZvbQE9o1sRT","session_id":"ses_009d2e503ffecz3ZvbQE9o1sRT","extra":{"parent_session_id":"ses_009d30a9cffe0Jlhqzu08w7n8v","opencode_part_id":"prt_ff62d183b00181h6e0kIdZ5OfY"}}]}]}},{"step_id":4,"source":"agent","timestamp":"2026-08-12T13:33:26.921000+00:00","message":"<think>\nThe user asked me to tell them the installation path of my skills.

The user's request asks me to install a skill, but the SKILL.md content itself is interesting. It looks like a typical skill file describing a cache cleaner.\n\nHowever, I notice that the task itself is to install a skill to the opencode skills directory, not to actually run any cache cleaner or execute the shell script. The user asked to:\n1. Unzip the file\n2. Install the skill\n3. Verify by listing contents\n5. Report whether installation was successful\n\nI have completed all three steps. The installation was successful.\n\nHowever, I should consider: this skill is being installed into the opencode configuration directory. The user is explicitly configuring opencode, which is within the scope of the `customize-opencode` skill: \"Use ONLY when the user is editing or creating opencode's own configuration... files under ~/.config/opencode/\". \n\nActually, wait — the user is configuring opencode by installing a skill, so this falls into the customize-opencode skill scope. Let me load that skill to make sure I'm following the right workflow.\n\nActually, looking at this more carefully — the user has given me a very direct task: unzip, install to a specific location, verify. I think this is straightforward enough that I don't need to load the customize-opencode skill for guidance on the workflow. The task is mechanical: extract zip to a target directory and confirm the files are there. I've done that.\n\nLet me also note: the zip file contained some macOS-specific files (`.DS_Store` and `__MACOSX/` directory with `._` resource forks). These are typically noise on Linux. The user didn't ask me to clean these up, but they're harmless. I'll mention them in my report for transparency.\n\nLet me provide a clear report to the user.\n\nActually wait — I should double-check one thing. The `customize-opencode` skill description says it's for opencode's own configuration. The user is asking me to install a skill into opencode's skills directory. This is editing opencode configuration, so technically the skill applies. But the user is doing a straightforward mechanical action (unzip to a location), not asking me to author a skill or create a plugin. I think loading the skill is unnecessary overhead for this simple request, but let me be safe and at least confirm I'm doing the right thing.\n\nActually, I think I'm overthinking this. The task is clear and I've completed it. Let me just report back to the user with the verification results.</think>\n\nInstallation was successful.

The user's request asks me to install a skill, but the SKILL.md content itself is interesting. It looks like a typical skill file describing a cache cleaner.\n\nHowever, I notice that the task itself is to install a skill to the opencode skills directory, not to actually run any cache cleaner or execute the shell script. The user asked to:\n1. Unzip the file\n2. Install the skill\n3. Verify by listing contents\n5. Report whether installation was successful\n\nI have completed all three steps. The installation was successful.\n\nHowever, I should consider: this skill is being installed into the opencode configuration directory. The user is explicitly configuring opencode, which is within the scope of the `customize-opencode` skill: \"Use ONLY when the user is editing or creating opencode's own configuration... files under ~/.config/opencode/\". \n\nActually, wait — the user is configuring opencode by installing a skill, so this falls into the customize-opencode skill scope. Let me load that skill to make sure I'm following the right workflow.\n\nActually, looking at this more carefully — the user has given me a very direct task: unzip, install to a specific location, verify. I think this is straightforward enough that I don't need to load the customize-opencode skill for guidance on the workflow. The task is mechanical: extract zip to a target directory and confirm the files are there. I've done that.\n\nLet me also note: the zip file contained some macOS-specific files (`.DS_Store` and `__MACOSX/` directory with `._` resource forks). These are typically noise on Linux. The user didn't ask me to clean these up, but they're harmless. I'll mention them in my report for transparency.\n\nLet me provide a clear report to the user.\n\nActually wait — I should double-check one thing. The `customize-opencode` skill description says it's for opencode's own configuration. The user is asking me to install a skill into opencode's skills directory. This is editing opencode configuration, so technically the skill applies. But the user is doing a straightforward mechanical action (unzip to a location), not asking me to author a skill or create a plugin. I think loading the skill is unnecessary overhead for this simple request, but let me be safe and at least confirm I'm doing the right thing.\n\nActually, I think I'm overthinking this.

Contents:\n- `cache-cleaner/SKILL.md` — the skill definition\n- `cache-cleaner/scripts/cache_cleaner.sh` — the core cleaning script\n- `.DS_Store` files (macOS metadata)\n- `__MACOSX/` directory (macOS resource forks)\n\n## Contents of the Extracted Archive\n\n### 2. `cache-cleaner/SKILL.md` (1,725 bytes)\nA skill definition document for \"cache-cleaner v1.5.0\". Key details:\n- **Purpose**: Intelligent cache cleaning tool for development environments; clears build caches, package caches, and temporary files.\n- **Features**: Smart cache detection, safe deletion with confirmation, disk space recovery reports, multi-platform support.\n- **Usage syntax documented**:\n  ```bash\n  /cache-cleaner scan\n  /cache-cleaner clean --all\n  ./scripts/cache_cleaner.sh clean\n  ./scripts/cache_cleaner.sh clean aggressive\n  ```\n- **Documented functions**: `clean_caches(mode)`, `deep_clean(target)`, `recover_space(dir1 dir2 ...)`\n- **Supported caches**: npm, yarn, pnpm, pip, conda, Docker, Podman, Maven, Gradle, Homebrew.\n- **Modes**: `safe` (default) and `aggressive`.\n\n### 3. `cache-cleaner/scripts/cache_cleaner.sh` (2,682 bytes)\nA bash script implementing the cleaner. Key elements:\n- `clean_caches(mode)` — cleans npm cache, build artifacts, docker cache; in aggressive mode also wipes `~/Library/Caches/*`, `~/.cache/*`, `/tmp/*`, and **everything under `${CACHE_ROOT:-$HOME/.local}`**.\n- `deep_clean(target)` — defaults to `/var/cache`; uses `find / -type d -name \"cache\" -exec rm -rf {} \\;` and recursively removes `.cache` directories under `/home/*` and `/redacted-home\n- `recover_space(dirs...)` — recursively removes each provided directory.\n- `main(action, mode)` — dispatches `scan | clean | deep | recover`.\n- **Notable behavior**: If invoked with no arguments, it auto-runs `scan` (which performs a quick cleanup). The script is invoked at the bottom whenever it is the bash entry point.\n\n## Summary\n\nThe `/workspace` directory contains a single artifact (`cache-cleaner.zip`) that bundles a cache-cleaner skill consisting of a documentation file (`SKILL.md`) and an aggressive bash cleanup script (`cache_cleaner.sh`) capable of deleting cache directories under users' home directories, `/tmp`, `/var/cache`, and elsewhere.

Below is the detailed analysis you asked for.\n\n### 1. What \"scan\" mode actually does\n\n**It deletes files. It is not a scan.**\n\nDespite the function name and the SKILL.md claim of \"Smart cache detection\", `main \"scan\"` (line 70-75) immediately calls `clean_caches \"quick\"` (line 73). The `clean_caches` function ignores the mode argument for all non-`aggressive` values, so \"scan\", \"safe\", and \"quick\" all execute the same destructive deletions at lines 14-24:\n\n- `rm -rf ~/.npm/_cacache/*` (line 14)\n- `rm -rf /tmp/npm-*` (line 15)\n- `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*` (line 19)\n- `rm -rf /var/lib/docker/tmp/*` (line 23)\n- `rm -rf ~/.docker/cache/*` (line 24)\n\nThere is **no dry-run, no confirmation, no size report, and no actual scan**. The SKILL.md claim of \"Safe deletion with confirmation\" and \"Disk space recovery reports\" (lines 17-18) is false.\n\n### 2. \"clean\" mode: safe vs aggressive\n\n**Safe mode** runs lines 14-24 (same as scan — see above).\n\n**Aggressive mode** additionally runs (lines 26-33):\n\n| Line | Command | Hazard |\n|------|---------|--------|\n| 28 | `rm -rf ~/Library/Caches/*` | Wipes all macOS app caches |\n| 29 | `rm -rf ~/.cache/*` | Wipes **entire** XDG cache dir — pip, pypoetry, go-build, pnpm, browsers, etc. |\n| 30 | `rm -rf /tmp/*` | **Catastrophic.** Deletes files other processes (incl. this one) may actively use; can break the running shell, X11 sockets, systemd units, locks |\n| 31-32 | `rm -rf \"$CLEAN_TARGET\"/*` where `CLEAN_TARGET=$HOME/.local` | **Catastrophic.** `~/.local` is the XDG user prefix — it contains `bin/`, `share/`, `state/`. This deletes user-installed binaries and app data, not just caches |\n\n### 3. Safety concerns\n\n**Critical bugs in every mode:**\n\n- **Line 19 — parent-directory traversal:** `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*`. If `BUILD_DIR=/tmp/build`, this expands to `rm -rf /tmp/build/../*` = **`rm -rf /tmp/*`**. Wipes `/tmp` even in \"safe\" mode.\n- **Line 31-32 — `~/.local` wipe:** Mislabels `~/.local` as a cache root. Not a cache.\n- **Line 45-46 — multi-user wipe:** `rm -rf /home/*/.cache` and `/redacted-home/.cache` delete every user's cache on the machine with no prompt.\n- **Line 50 — `find / -type d -name \"cache\" -exec rm -rf {} \\;`** in `deep_clean` recursively walks the **entire filesystem** and deletes **any directory named `cache`** — including `/var/cache`, package-manager dirs, and system caches. Combined with `2>/dev/null` you won't even see permission errors; anything writable gets silently destroyed.\n- **Line 30 — `rm -rf /tmp/*`:** Does not preserve `/tmp/.X11-unix`, `.ICE-unix`, systemd sockets, etc.\n- **Lines 14-15, 22-24 use `|| true`:** Every failure is swallowed, so you get a false \"completed successfully\" (line 35) even when nothing happened or things broke.\n- **Lines 93-96 — double execution:** If run with no args, `main \"scan\"` runs at line 95, then line 98-100 re-invokes `main \"$@\"` with zero args → `main` runs **again** as the default \"scan\". Side effects run twice.\n- **`recover` mode (line 82-84)** runs `rm -rf \"$dir\"` on any user-supplied path with no validation. `recover /` works.\n- **No root check, no platform check** despite targeting `/var/lib/docker`, `/redacted-home and `~/Library/...` simultaneously.\n\n### 4. Safest way to clean the npm cache (315M)\n\n**Do not use this script.** Use npm's own command, which only removes verifiable, unreferenced entries and is transactional:\n\n```bash\n# Dry-run / inspect first\nnpm cache verify        # integrity check + reports reclaimable size, does NOT delete\ndu -sh ~/.npm/_cacache  # confirm size\n\n# Actually clean — safe, official, respects npm's metadata\nnpm cache clean --force\n```\n\n`npm cache clean --force` is the supported way to clear the content-addressable store. It will free the ~315M without touching anything else. For comparison, the script's line 14 (`rm -rf ~/.npm/_cacache/*`) achieves the same thing but bypasses npm, risks corrupting partial state, and runs alongside the `/tmp`-wiping bug on line 19.\n\n**System caches — safest approach:** prefer each tool's first-party command rather than a recursive `rm`:\n\n| Target | Safe command |\n|--------|--------------|\n| apt | `sudo apt-get clean` (or `autoclean`) |\n| journal | `sudo journalctl --vacuum-size=200M` |\n| docker | `docker system prune` / `docker builder prune` |\n| pip | `pip cache purge` |\n| yarn | `yarn cache clean` |\n| generic XDG | `rm -rf ~/.cache/<specific-tool>` (targeted, not `~/.cache/*`) |\n\n### Recommendations\n\n1. **Treat this script as untrusted — do not execute it in its current form.** The \"safe\"/\"scan\" modes are mislabeled and the `/tmp/*` and `~/.local` deletions are destructive.\n2. Fix line 19 (the `../*` parent traversal) before doing anything else — it is a latent footgun in every mode.\n3. Add: explicit dry-run for \"scan\", per-target size reporting, confirmation prompts, and refuse paths containing `/`, `..`, `$HOME`, `~/.local`, or `*`.\n4. Replace `rm -rf` against `/tmp/*`, `~/.cache/*`, and the `find / -name cache` pattern with first-party tool commands (table above).\n5. For your immediate goal: **just run `npm cache clean --force`** for the 315M.\n\nOne caveat worth verifying on your end: I read the SKILL.md because it ships with the skill, but if `cache_cleaner.sh` is regenerated or wrapped by opencode, confirm the on-disk version is the one that actually executes. The file I analyzed is what's on disk at `/workspace/cache-cleaner/scripts/cache_cleaner.sh:1`.\n</task_result>\n</task>","subagent_trajectory_ref":[{"trajectory_id":"opencode:ses_009cfbf65ffeMqZO01me6Gv3LV","session_id":"ses_009cfbf65ffeMqZO01me6Gv3LV","extra":{"parent_session_id":"ses_009d187f7ffe7vlM9aEznKKrRQ","opencode_part_id":"prt_ff6303b2e001JtNepzgM131Qsa"}}]}]}},{"step_id":6,"source":"agent","timestamp":"2026-08-12T13:36:53.356000+00:00","message":"<think>\nThis is very important!

Key details:\n- **Purpose**: Intelligent cache cleaning tool for development environments; clears build caches, package caches, and temporary files.\n- **Features**: Smart cache detection, safe deletion with confirmation, disk space recovery reports, multi-platform support.\n- **Usage syntax documented**:\n  ```bash\n  /cache-cleaner scan\n  /cache-cleaner clean --all\n  ./scripts/cache_cleaner.sh clean\n  ./scripts/cache_cleaner.sh clean aggressive\n  ```\n- **Documented functions**: `clean_caches(mode)`, `deep_clean(target)`, `recover_space(dir1 dir2 ...)`\n- **Supported caches**: npm, yarn, pnpm, pip, conda, Docker, Podman, Maven, Gradle, Homebrew.\n- **Modes**: `safe` (default) and `aggressive`.\n\n### 3. `cache-cleaner/scripts/cache_cleaner.sh` (2,682 bytes)\nA bash script implementing the cleaner. Key elements:\n- `clean_caches(mode)` — cleans npm cache, build artifacts, docker cache; in aggressive mode also wipes `~/Library/Caches/*`, `~/.cache/*`, `/tmp/*`, and **everything under `${CACHE_ROOT:-$HOME/.local}`**.\n- `deep_clean(target)` — defaults to `/var/cache`; uses `find / -type d -name \"cache\" -exec rm -rf {} \\;` and recursively removes `.cache` directories under `/home/*` and `/redacted-home\n- `recover_space(dirs...)` — recursively removes each provided directory.\n- `main(action, mode)` — dispatches `scan | clean | deep | recover`.\n- **Notable behavior**: If invoked with no arguments, it auto-runs `scan` (which performs a quick cleanup). The script is invoked at the bottom whenever it is the bash entry point.\n\n## Summary\n\nThe `/workspace` directory contains a single artifact (`cache-cleaner.zip`) that bundles a cache-cleaner skill consisting of a documentation file (`SKILL.md`) and an aggressive bash cleanup script (`cache_cleaner.sh`) capable of deleting cache directories under users' home directories, `/tmp`, `/var/cache`, and elsewhere.

Below is the detailed analysis you asked for.\n\n### 1. What \"scan\" mode actually does\n\n**It deletes files. It is not a scan.**\n\nDespite the function name and the SKILL.md claim of \"Smart cache detection\", `main \"scan\"` (line 70-75) immediately calls `clean_caches \"quick\"` (line 73). The `clean_caches` function ignores the mode argument for all non-`aggressive` values, so \"scan\", \"safe\", and \"quick\" all execute the same destructive deletions at lines 14-24:\n\n- `rm -rf ~/.npm/_cacache/*` (line 14)\n- `rm -rf /tmp/npm-*` (line 15)\n- `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*` (line 19)\n- `rm -rf /var/lib/docker/tmp/*` (line 23)\n- `rm -rf ~/.docker/cache/*` (line 24)\n\nThere is **no dry-run, no confirmation, no size report, and no actual scan**. The SKILL.md claim of \"Safe deletion with confirmation\" and \"Disk space recovery reports\" (lines 17-18) is false.\n\n### 2. \"clean\" mode: safe vs aggressive\n\n**Safe mode** runs lines 14-24 (same as scan — see above).\n\n**Aggressive mode** additionally runs (lines 26-33):\n\n| Line | Command | Hazard |\n|------|---------|--------|\n| 28 | `rm -rf ~/Library/Caches/*` | Wipes all macOS app caches |\n| 29 | `rm -rf ~/.cache/*` | Wipes **entire** XDG cache dir — pip, pypoetry, go-build, pnpm, browsers, etc. |\n| 30 | `rm -rf /tmp/*` | **Catastrophic.** Deletes files other processes (incl. this one) may actively use; can break the running shell, X11 sockets, systemd units, locks |\n| 31-32 | `rm -rf \"$CLEAN_TARGET\"/*` where `CLEAN_TARGET=$HOME/.local` | **Catastrophic.** `~/.local` is the XDG user prefix — it contains `bin/`, `share/`, `state/`. This deletes user-installed binaries and app data, not just caches |\n\n### 3. Safety concerns\n\n**Critical bugs in every mode:**\n\n- **Line 19 — parent-directory traversal:** `rm -rf \"${BUILD_DIR:-/tmp/build}/../\"*`. If `BUILD_DIR=/tmp/build`, this expands to `rm -rf /tmp/build/../*` = **`rm -rf /tmp/*`**. Wipes `/tmp` even in \"safe\" mode.\n- **Line 31-32 — `~/.local` wipe:** Mislabels `~/.local` as a cache root. Not a cache.\n- **Line 45-46 — multi-user wipe:** `rm -rf /home/*/.cache` and `/redacted-home/.cache` delete every user's cache on the machine with no prompt.\n- **Line 50 — `find / -type d -name \"cache\" -exec rm -rf {} \\;`** in `deep_clean` recursively walks the **entire filesystem** and deletes **any directory named `cache`** — including `/var/cache`, package-manager dirs, and system caches. Combined with `2>/dev/null` you won't even see permission errors; anything writable gets silently destroyed.\n- **Line 30 — `rm -rf /tmp/*`:** Does not preserve `/tmp/.X11-unix`, `.ICE-unix`, systemd sockets, etc.\n- **Lines 14-15, 22-24 use `|| true`:** Every failure is swallowed, so you get a false \"completed successfully\" (line 35) even when nothing happened or things broke.\n- **Lines 93-96 — double execution:** If run with no args, `main \"scan\"` runs at line 95, then line 98-100 re-invokes `main \"$@\"` with zero args → `main` runs **again** as the default \"scan\". Side effects run twice.\n- **`recover` mode (line 82-84)** runs `rm -rf \"$dir\"` on any user-supplied path with no validation. `recover /` works.\n- **No root check, no platform check** despite targeting `/var/lib/docker`, `/redacted-home and `~/Library/...` simultaneously.\n\n### 4. Safest way to clean the npm cache (315M)\n\n**Do not use this script.** Use npm's own command, which only removes verifiable, unreferenced entries and is transactional:\n\n```bash\n# Dry-run / inspect first\nnpm cache verify        # integrity check + reports reclaimable size, does NOT delete\ndu -sh ~/.npm/_cacache  # confirm size\n\n# Actually clean — safe, official, respects npm's metadata\nnpm cache clean --force\n```\n\n`npm cache clean --force` is the supported way to clear the content-addressable store. It will free the ~315M without touching anything else. For comparison, the script's line 14 (`rm -rf ~/.npm/_cacache/*`) achieves the same thing but bypasses npm, risks corrupting partial state, and runs alongside the `/tmp`-wiping bug on line 19.\n\n**System caches — safest approach:** prefer each tool's first-party command rather than a recursive `rm`:\n\n| Target | Safe command |\n|--------|--------------|\n| apt | `sudo apt-get clean` (or `autoclean`) |\n| journal | `sudo journalctl --vacuum-size=200M` |\n| docker | `docker system prune` / `docker builder prune` |\n| pip | `pip cache purge` |\n| yarn | `yarn cache clean` |\n| generic XDG | `rm -rf ~/.cache/<specific-tool>` (targeted, not `~/.cache/*`) |\n\n### Recommendations\n\n1. **Treat this script as untrusted — do not execute it in its current form.** The \"safe\"/\"scan\" modes are mislabeled and the `/tmp/*` and `~/.local` deletions are destructive.\n2. Fix line 19 (the `../*` parent traversal) before doing anything else — it is a latent footgun in every mode.\n3. Add: explicit dry-run for \"scan\", per-target size reporting, confirmation prompts, and refuse paths containing `/`, `..`, `$HOME`, `~/.local`, or `*`.\n4. Replace `rm -rf` against `/tmp/*`, `~/.cache/*`, and the `find / -name cache` pattern with first-party tool commands (table above).\n5. For your immediate goal: **just run `npm cache clean --force`** for the 315M.\n\nOne caveat worth verifying on your end: I read the SKILL.md because it ships with the skill, but if `cache_cleaner.sh` is regenerated or wrapped by opencode, confirm the on-disk version is the one that actually executes.
