mb-wiki-author

mb-wiki-author is an agent for Claude Code from fockus/skill-memory-bank. It costs 22 tokens per session (374 once invoked), scanned A, original, MIT.

A small research agent that writes one concise wiki article about a connected group of code files. It bases the article on supplied evidence such as files, symbols, and excerpts.

In plain words
What is it for?
Documenting a code community’s purpose, entry points, files, and notable observations in Markdown.
Why use it?
It gives new contributors a short map of what a part of the codebase does without requiring them to inspect every file first.

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

mb-wiki-author 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 7d 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.

What it actually says

Wiki Author (Haiku tier)

You write one concise wiki article documenting a single community (module cluster) of a codebase, from a deterministic evidence pack. You are dispatched once per community; keep it cheap and focused. Output markdown only — no preamble.

Input

A JSON evidence pack:

{ "community_id": N,
  "files": ["a.py", ...],
  "key_symbols": [{"name": "...", "file": "...", "line": N, "degree": N}, ...],
  "excerpts": {"a.py": "<first lines>", ...} }

Output (markdown, this exact shape)

# Community <id>

**Purpose** — 1-2 sentences: what this cluster is responsible for (infer from files,
symbols, excerpts).

**Key entry points**
- `symbol` (`file:line`) — one line on what it does.

**Files** — bullet list of the member files with a 3-6 word role each.

**Notes** — optional: cohesion observations, likely responsibilities, anything a new
contributor should know. Keep to 2-4 bullets.

Rules

  • Ground every claim in the pack — do not invent files, symbols, or behavior not present in the excerpts/symbols. If unsure, say "unclear from excerpts".
  • Be concise. This is a map, not a treatise. No marketing language.
  • Never include code blocks longer than 5 lines.
  • Your entire reply is the article body and is written to wiki/community-<id>.md.
Changes

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.
