config

config is a skill for Claude Code from MereWhiplash/engram-cogitator. It costs 45 tokens per session (1,591 once invoked), scanned A, original, MIT.

A guide for changing project settings used by the coding workflow, including test, lint, and build commands, branch naming rules, and feature toggles. Settings are kept partly in shared project memory and partly in a version-controlled config file.

In plain words
What is it for?
Use it to update project configuration, set commands, change branching rules, or enable workflow features such as graphify.
Why use it?
It gives one process for viewing, changing, saving, and checking workflow settings. This reduces the chance that the agent uses the wrong commands or 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

config 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.

Configure Cogitation

Cogitation reads config from two places:

  • EC memory (type: config) — commands and conventions: test/lint/build commands, branch convention. Managed in this skill's Steps 1–5.
  • .cogitation/config.json (repo root, version-controlled) — feature toggles. Defaults are conservative (everything off). See "Feature toggles" below.

Announce: "I'm using the config skill to manage project settings."

The Flow

Load Current → Present → Modify → Save → Verify

Step 1: Load Current Configuration

ec_search:
  query: project config
  type: config
  area: project

If no config found:

"No configuration found. Want to initialize cogitation for this project?"

If yes → Use @cog-init

Step 2: Present Current Settings

## Current Configuration

| Setting | Value |
|---------|-------|
| Test command | `pnpm test` |
| Lint command | `pnpm lint` |
| Build command | `pnpm build` |
| Branch convention | `feat/fix/chore` |

What would you like to change?

Step 3: Modify Settings

Use AskUserQuestion:

{
  "questions": [{
    "question": "Which setting do you want to modify?",
    "header": "Setting",
    "options": [
      { "label": "Test command", "description": "Command to run tests" },
      { "label": "Lint command", "description": "Command to check types/lint" },
      { "label": "Build command", "description": "Command to build project" },
      { "label": "Branch convention", "description": "How branches are named" }
    ],
    "multiSelect": true
  }]
}

For each selected setting, ask for the new value:

{
  "questions": [{
    "question": "What should the test command be?",
    "header": "Test",
    "options": [
      { "label": "pnpm test", "description": "pnpm package manager" },
      { "label": "npm test", "description": "npm package manager" },
      { "label": "go test ./...", "description": "Go testing" },
      { "label": "cargo test", "description": "Rust testing" }
    ],
    "multiSelect": false
  }]
}

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.
