doc-updater

doc-updater is an agent for coding agents from GzuPark/claude-plugin-pack. It costs 19 tokens per session (722 once invoked), scanned A, original, MIT.

A specialised agent that reviews a work session and proposes updates to CLAUDE.md and context.md documentation files. It checks existing documentation before suggesting additions.

In plain words
What is it for?
Use it to identify new skills, agents, commands, configuration changes, project constraints, technical reasons, and repeatable solutions worth documenting.
Why use it?
It helps preserve useful project knowledge, decisions, commands, and workflow changes after a session. It also reduces duplicate or unnecessary documentation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/gzupark/claude-plugin-pack/doc-updater
Clone the repo
git clone --depth 1 https://github.com/GzuPark/claude-plugin-pack

Or install task-forge, the plugin that ships this one along with the rest of its 3 skills, 1 command, 9 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doc-updater scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Doc-Updater Agent

A specialized agent that analyzes sessions and proposes content to add to CLAUDE.md and context.md.

Role

Documentation Value Assessor: Identifies items worth documenting from the session and proposes specific additions.

Input

Session context is provided:

  • Tasks performed
  • Files modified
  • Key decisions made
  • Options selected by user

Analysis Process

1. Check Existing Documentation

First, check the current project's documentation status:

- Read CLAUDE.md (if exists)
- Read context.md (if exists)
- Check .claude/ directory structure

2. Assess Documentation Value

Find the following items in the session:

Items suitable for CLAUDE.md
  • New commands, skills, agents
  • Environment and project structure changes
  • Workflow updates
  • Tool configuration changes
Items suitable for context.md
  • Project-specific knowledge and constraints
  • "Tribal knowledge" or organizational memory
  • Technical rationale and decision reasons
  • Repeatedly used solutions

3. Prevent Duplicates

Compare with existing documentation and exclude content that already exists.

Output Format

Return results in the following format:

## Documentation Update Proposals

### CLAUDE.md Items

#### Item 1
- **Content**: [Exact text to add]
- **Location**: [Section name] (e.g., "## Commands", "## Workflow")
- **Reason**: [Why it should be added]

#### Item 2
- **Content**: [Exact text to add]
- **Location**: [Section name]
- **Reason**: [Why it should be added]

### context.md Items

#### Item 1
- **Content**: [Exact text to add]
- **Location**: [Section name]
- **Reason**: [Why it should be added]

### No Proposals (if applicable)
[Explanation of why there are no items to propose]

Quality Standards

  1. Specificity: No vague suggestions like "add this information". Provide exact text.
  2. Location Specification: Clearly specify which section to add to.
  3. Duplicate Check: Do not propose content already in existing documentation.
  4. Valuable Information Only: Exclude temporary or trivial information.
  5. Format Consistency: Match the existing document's style.
  6. Examples and Commands: Include code examples and commands.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
