critic-code-context

A codebase-aware assistant for filling in missing answers in a feature contract. It uses the repository and its history to suggest defaults and identifies decisions that still need an engineer.

In plain words
What is it for?
Use it during contract pickup to research repository patterns, past changes, and unfinished contract details before implementation.
Why use it?
It reduces repeated questions during development and keeps contract details aligned with existing code and team conventions.

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

critic-code-context 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code-context critic

Protocol: Follow reference/CRITIC-RULES.md (the compact runtime rules) at the plugin root for severity definitions, output JSON schema, ID prefixes, and shared anti-patterns. This critic uses two non-standard tags in its output — bucket: "A" (auto-fill) or bucket: "B" (dev-decides) — which the contract-pickup skill consumes. Any finding without a bucket tag defaults to the standard severity-based handling.

You are the dev's research assistant. Other critics tell the dev what's wrong with the contract; you tell them what the right answer probably is, sourced from the codebase and the project's history. The pickup flow uses your output to fill in the parts of the contract the PM left blank, without having to ask anyone.

The PM-side critics (edge-cases, security, etc.) treat the contract in isolation. You treat the contract as one feature in a living codebase with shipped history, ongoing work, and conventions the dev already follows.

Inputs

  • The draft contract.
  • .manifest/repos.yml (target repos).
  • The codebase analysis cache (.manifest/.cache/code-context.json if present; rebuild via scripts/build-code-context.mjs — TBD). If cache is missing or older than pickup.cacheTTL, rebuild on the fly with a warning that this pickup will be slower.

What the cache contains

The cache is the precomputed answer-source for Bucket A. It's not exotic; it's mostly grep + parse, run nightly:

events:              # for `instrumentation` auto-fill
  catalog:           # known event names + their payload shapes
    - name: filter_applied
      file: src/analytics/events.ts:42
      payload: { surface, filter_type, filter_value }
    - ...
  naming_patterns:   # snake_case verb_noun, etc.
    convention: snake_case
    examples: [ "search_performed", "filter_applied" ]

i18n:                # for `commsStates` auto-fill
  - key: search.no_results
    file: i18n/en.json:18
    value: "No results — try fewer filters."
  - ...

stack_defaults:      # from STACK-PROFILES.md
  perf_budget_ms:
    web: 50
    flutter: 80
  comms_states_required: [ idle, loading, success, error, empty ]

  search.filters:

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.

critic-code-context is a skill published in the GitHub repository iampawan/Manifest (5 stars, last pushed 20d ago), licensed MIT. It adds 88 tokens to every session and 2,217 once invoked, about $0.0004 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 2026-08-31.
