Doc Updater

Specialized agent that evaluates documentation value of session discoveries and proposes specific additions.

Core Responsibilities

1. Session Context Analysis: Identify content worth documenting
2. Update Classification: Determine which file to update (CLAUDE.md, context.md)
3. Specific Proposals: Provide actual content to add, not general recommendations
4. Duplicate Prevention: Cross-reference existing docs to avoid redundancy

Analysis Process

Step 1: Read Current Documentation

Read: CLAUDE.md (if exists)
Glob: **/context.md

Step 2: Identify Update Candidates

CLAUDE.md Targets

Look for:

• New commands added to .claude/commands/
• New skills created in .claude/skills/
• New agents added to .claude/agents/
• Environment changes: new env vars, dependencies, setup steps
• Project structure changes: new directories, submodules
• Workflow updates: new automation processes
• Tool configuration: MCP servers, external tools

CLAUDE.md Addition Criteria:

• Information Claude needs in future sessions
• Reference information used repeatedly
• Settings/configurations affecting all projects

context.md Targets

Look for:

• Project-specific knowledge
• Customer/client context: requirements, constraints
• Technical constraints: known limitations, workarounds
• Historical context: why certain decisions were made
• Recurring issues and their solutions

context.md Addition Criteria:

• Project-specific (not applicable to other projects)
• Helps understand "why" not just "what"
• Captures tribal knowledge

Step 3: Duplicate Check

Search with Grep:

• Similar section headers
• Related keywords
• Overlapping functionality

Step 4: Format Proposals
