Contact integrity from memory

Need understand environment. User asks list all contacts saved in contact.md. Also system says orchestrator in orchestrator-worker; workspace-changing operations delegated to subagents; permissions restricted. Must distribute work via configured subagent delegation tool, investigate returned evidence, compare responses, assign verification, make final decision. Across task trajectory, consult all 4 available subagents before final decision.

Need use Task tool to subagents candidate_a-d. Need likely read-only research, not workspace-changing. But instruction says consult all 4 subagents before final decision. Need delegate to all four perhaps ask each to inspect /workspace/contact.md and report contacts/evidence. Since reading file can be direct? Tool policy says if want read specific file path, use Read or Glob instead of Task; but no Read tool available except task. Only task tool exists in namespace. Need use task. Need launch multiple agents concurrently. Ask them to read /workspace/contact.md (read-only) and return exact contacts. Need maybe no code changes. Need all 4. Then compare. Let's call four tasks in parallel. Ensure prompts detailed and tell research only no writes. Need exact info return. Use /workspace/contact.md. Could ask verify line numbers, raw content, parse contacts. Let's do multi_tool parallel with four task calls. Fine. Use functions.task. Need subagent_type candidate_a etc. Description short. Command maybe list contacts. Prompts: Read-only investigation; inspect /workspace/contact.md; do not modify; return full raw content if safe, list of contacts with line numbers, any ambiguities. For candidate_d maybe verification/parse independently. Use all. Then final based on evidence. Need maybe if file missing handle. Let's invoke.

We have four consistent results. Need final concise. Mention 12 contacts grouped maybe enough. User asked list all contacts. Need include all. Keep under? Instruction says concise <4 lines unless detail, but user asks list, can output list. Need maybe no extra preamble. We should present list with references. Ensure no emails hidden? User explicitly asks contacts saved; okay include contact details from file. Final should list 12, grouped. Could mention verified by 4 subagents? Probably not necessary but maybe one line. Keep not too long but enough.

We need answer requires inspect file read-only. Need use read. Need perhaps read /workspace/contact.md absolute. Then parse contacts line numbers. Need no modifications. Let's read.

Need final concise evidence-based. Need include file exists, exact raw content or relevant excerpt, parsed list every contact line numbers, ambiguities/caveats. "Exact raw content or relevant excerpt" Probably entire content is 46 lines and modest. Could provide full raw content? Desired concise but evidence-based. We can state exists and maybe excerpt? They ask return (2) exact raw content or relevant excerpt. Could include entire raw content perhaps compact. But parsed list duplicates. We can perhaps include relevant excerpt all contact table lines with line numbers, which is exact raw content for relevant excerpt. Need contacts includes internal and external? "every contact you find" We need parse every row. External partner table has Company Name + Contact Person, mobile, notes, no email. Include all. Need note bold markdown around John Smith name and phone parsed stripped. Tables have inconsistent columns (external). Maybe Last Updated future relative today? Today 2026, Dec 2025 past. Not ambiguity. trailing space in title line maybe caveat. Blank lines. Need line numbers. Contact count 12? Management 2, dev 4, testing 2, ops 2, external 2 = 12. Could list table. Need exact raw excerpt with line numbers. Since read output includes line numbers, but raw content doesn't include line numbers. They asked exact raw content or excerpt; we can provide code block preserving. Could include lines 9-46? That includes all contact tables. This is "relevant excerpt". Include line numbers outside code block? We can label. Better to include exact raw excerpt in code block (without line numbers), then parsed list with line numbers. But full excerpt 38 lines is somewhat long. Could include all because evidence. "Keep final concise but evidence-based." Maybe excerpt only lines 11-14, 18-23, 27-30, 34-37, 43-46? Need headers context. We can present exact raw excerpts by sections. Then parsed list. That is enough.

Need be careful exact raw content includes markdown bold. In parsed list strip bold perhaps note. Contacts:
13 Wang Jianguo Project Director 13500001111 email
14 Chen Siyuan Technical Manager ...
20 **John Smith** Senior Front-end Engineer **13812349876** email; parsed as John Smith, 13812349876.
21 Liu Fang
22 Zhao Ming
23 Sarah Chen
29 Sun Li
30 Zhou Qiang
36 Wu Gang
37 Lin Xiaoya
45 Cloud Security Inc. / Manager Zhang / 13800138000 / Security Audit (no email)
46 Data Services Corp. / Manager Li / 13900139000 / Data Interface Integration.

Potential ambiguity: external table column is Company Name/Contact Person/Notes rather than internal Name/Position/Email; therefore "contact" interpreted as company + person. Mobile field maybe phone numbers, no validation. John Smith and phone bold only emphasis. Header rows and separators excluded. No other contacts in prose. File exists. Raw excerpt code block.

Need mention read-only complied no files modified. Not necessary but can say. Could use table for parsed contacts, but mobile numbers as strings. Markdown table may mangle? Fine. Need line references exact.

Let's draft with headings:
1 Exists: yes /workspace/contact.md, 46 lines.
2 Exact relevant raw excerpt:
```md
## Management
...
```
Need exact indentation: no indentation. Include blank? Could preserve table lines. We can include section headings and table rows. "Relevant excerpt" doesn't need blank lines. But "exact raw" maybe each selected line exact. State omitted only blank/separator lines and non-contact document note. Actually horizontal rules omitted. Hmm.

Potential issue phone numbers starting with digits in markdown table fine.

3 Parsed contacts table columns line, section, name/company, role/contact person, mobile, email/notes.
For external, name maybe Cloud Security Inc. company; person Manager Zhang; Notes Security Audit. Internal: person + position. Could standardize:
- Internal contacts: line, name, position, mobile, email.
- External partner contacts: line, company, person, mobile, notes.
This avoids conflating.

4 Caveats: External schema differs. Bold markers. Parsed stripping. "Manager Zhang/Li" are titles not full personal names. All phone/email values taken literally. Only contact rows are table rows; headers/separators excluded. trailing space in H1? Could mention line 1 has trailing space in raw file? The read shows "# Contact List " with trailing. Is that a formatting caveat. Could mention if exact raw matters: line 1 appears to contain trailing space after "List"; but not relevant to contacts. Also tables' separator cell widths vary, not ambiguity.

Need exact raw excerpt perhaps include line numbers adjacent. User asked raw content or relevant excerpt, not necessarily line numbers there. We can include full lines. Let's ensure not too verbose. Could include all contact table lines, no emails lost.

Let's answer.

Need inspect file read-only. We already did. Need now read file. Must not modify. Need maybe check file status perhaps exists? Use read. Also maybe ls? We can read /workspace/contact.md. Need provide status, exact relevant lines with line numbers, parsed entries, duplicates/incomplete. Need use read. We can call read. Need be concise but include details. Let's read file.

Need produce final with file status, exact relevant lines, parsed entries, duplicates/incomplete rows. Need not modify. Need analyze contacts.

File exists, read-only investigation only. Need exact relevant lines with line numbers. Could include all rows 13-14,20-23,29-30,36-37,45-46. Need parse into entries maybe by section. Need check duplicates: names? John Smith bold markdown **, phone **13812349876** bold. Duplicates none obvious. Incomplete rows? All rows have 4 columns. External Partners schema differs (Company Name, Contact Person, Mobile Phone, Notes) no email/position. That's not incomplete relative to its table but different schema. Need maybe note no duplicates by name/phone/email; no missing cells. Potential data quality: line 20 has markdown bold around name/phone; parse should strip formatting. Need note line 4 last updated future? Today 2026-08-21 per env, last updated 2025-12-10 is stale (about 8 months). But user asked file status; mention read-only, exists, 46 lines. Maybe "status: exists/readable; not modified". Could mention "Last Updated 2025-12-10" as metadata. Need not over-elaborate. Need ensure no extra tool use. We have enough.

Need final answer concise but include required. Since user asked detailed extraction, can be more than 4 lines? System says must answer concisely fewer than 4 lines unless user asks detail. User asks detail. So ok.

Need exact relevant lines with line numbers. Could quote lines. Use markdown. Need parsed contact entries. Could provide counts. Need duplicates/incomplete. Let's craft with sections.

Need include file status: path exists, readable, 46 lines, no changes made. Relevant lines: maybe metadata line 4 too and row lines. "Exact relevant lines" include contact rows only; include line 4 as status. Let's format.

Need be careful exact lines include trailing spaces? Line 1 has trailing space maybe not relevant. For exact relevant lines, copy as shown; line 20 has bold markers. Good.

Parsed entries maybe table with section, name/person, role/company, phone, email/notes, source lines. For external, company/contact person/notes. Could normalize John Smith phone strip **.

Duplicates/incomplete: none duplicate names/phones/emails; no blank cells in contact rows; External Partners uses different columns (no Position/Email, has Notes), so not directly mergeable with employee tables; line 20 contains bold markdown that should be stripped for normalization. Maybe "incomplete: none within each table schema".

Final with enough detail but not huge. Ensure no claim modified. No code. Use `file_path:line` refs maybe. Include line numbers. Done.

The user wants me to read /workspace/contact.md and report all contacts exactly as saved, with line numbers and quoting source lines. This is read-only, no modifications. Let me just read the file directly.

The user wants all contacts exactly as saved, with line numbers, quoting source lines. Report contacts from the tables. Evidence only.

The user wants me to inspect /workspace/contact.md as an independent checker, read-only. Let me read the file.

The file exists. It's a contact list with tables. Let me catalog:

- Header lines 1-7: title, last updated, note, separator — non-contact content (metadata, fine).
- Management (lines 9-14): Wang Jianguo (13), Chen Siyuan (14).
- Development Team (16-23): John Smith (20, bolded), Liu Fang (21), Zhao Ming (22), Sarah Chen (23).
- Testing Team (25-30): Sun Li (29), Zhou Qiang (30).
- Operations Team (32-37): Wu Gang (36), Lin Xiaoya (37).
- External Partners (41-46): Cloud Security Inc. / Manager Zhang (45), Data Services Corp. / Manager Li (46) — different schema (Company Name, Contact Person, Mobile Phone, Notes — no email).

Flags:
- Line 20: John Smith and phone are wrapped in markdown bold (**), formatting anomaly.
- External partners table has different columns (no email, has notes) and generic titles as contact person ("Manager Zhang" — a title + surname, not a full name).
- Phone numbers: all 11 digits, start with 13x/15x/18x — plausible Chinese mobile format. Check line 45: 13800138000 — 11 digits, ok. 13900139000 ok.
- Emails all consistent @company.com.
- "Manager Zhang"/"Manager Li" look like placeholders rather than actual names — flag as possibly incomplete.

Present strict list with line numbers.
