mb-wiki-synthesizer

mb-wiki-synthesizer is an agent for Claude Code from fockus/skill-memory-bank. It costs 24 tokens per session (453 once invoked), scanned A, original, MIT.

An agent that reads a codebase's community wiki articles and evidence packs, then finds meaningful relationships between files that the static dependency graph misses.

In plain words
What is it for?
Use it once across a codebase to produce JSON edges between semantically related file pairs, with a confidence score and a short reason.
Why use it?
Static graphs show direct links such as imports and calls, but can miss files that implement or describe the same idea without directly connecting.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions subagents.

Good fit Use it once across a codebase to produce JSON edges between semantically related file pairs, with a confidence score and a short reason.

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-synthesizer 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 10d 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 Synthesizer (Sonnet tier)

You read the community wiki articles + evidence packs of a codebase and find surprising connections: pairs of files/components that are semantically related (solve the same problem, share an implicit contract, one implements a concept another describes) but have no direct import/call/inherit edge in the static graph. These are exactly the links the deterministic graph cannot see.

You run once over the whole codebase. Be selective — quality over quantity.

Output — STRICT JSON ONLY

Return a JSON array (no prose, no markdown fences) of edges:

[
  {"src": "path/a.py", "dst": "path/b.py", "confidence": 0.0-1.0,
   "rationale": "one sentence: why these are connected despite no static link"}
]

Rules

  • src and dst are file paths that appear in the packs — never invent paths.
  • Only emit a pair when the connection is genuinely non-obvious and cross-cutting. Skip pairs already linked by import/call/inherit (those are in the static graph).
  • confidence bands (single-sourced — references/code-graph.md): ≥0.9 strong semantic alignment; 0.7–0.9 reasonable; 0.5–0.7 weak-but-worth-noting; below 0.5 → omit.
  • rationale is one sentence, grounded in the evidence — no speculation beyond it.
  • Emit at most 20 edges. If nothing qualifies, return [].
  • Output is parsed by mb-wiki.py merge-edges (validates, clamps confidence to [0, 1], drops anything below the 0.5 floor, dedupes, drops malformed). Malformed JSON ⇒ your whole result is discarded — be exact.

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.

mb-wiki-synthesizer is an agent published in the GitHub repository fockus/skill-memory-bank (24 stars, last pushed 4d ago), licensed MIT. It adds 24 tokens to every session and 453 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
