cog-init

cog-init is a skill for Claude Code from MereWhiplash/engram-cogitator. It costs 37 tokens per session (1,286 once invoked), scanned A, original, MIT.

A first-time setup guide for Cogitation, a project memory system that stores useful context for later work.

In plain words
What is it for?
Use it to initialize project folders, configure Cogitation, and save the project's starting context.
Why use it?
It checks whether the required Engram Cogitator service is available and avoids overwriting existing project context without asking.

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

cog-init 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.

Initialize Cogitation

First-time setup for a project. Creates the foundation for memory-enhanced workflows.

Announce: "I'm using the init skill to set up cogitation for this project."

The Flow

Verify EC → Check Existing → Scaffold → Configure → Store

Step 1: Verify EC Connection

Test that Engram Cogitator is running:

ec_search: test connection

If EC unavailable: Stop. Cogitation requires EC.

"EC connection failed. Please ensure engram-cogitator is running. See: https://github.com/MereWhiplash/engram-cogitator"

Step 2: Check for Existing Context

Search for prior initialization:

ec_search: project config
ec_search: cogitation initialized

If found: Ask before reinitializing.

{
  "questions": [{
    "question": "This project already has cogitation context. What would you like to do?",
    "header": "Existing",
    "options": [
      { "label": "Keep existing", "description": "Exit without changes" },
      { "label": "Reconfigure", "description": "Update settings, keep memories" },
      { "label": "Fresh start", "description": "Clear all and reinitialize" }
    ],
    "multiSelect": false
  }]
}

Step 3: Scaffold Directories

Create standard directories if they don't exist:

mkdir -p docs/designs docs/plans docs/sketches

Step 4: Detect Project Stack

Analyze the project to suggest defaults:

ls -la

Look for:

  • package.json → Node/npm/pnpm/bun
  • go.mod → Go
  • Cargo.toml → Rust
  • pyproject.toml / requirements.txt → Python
  • Makefile → Make-based

Step 5: Configure Commands

Use AskUserQuestion to confirm/customize commands:

{
  "questions": [
    {
      "question": "What command runs your tests?",
      "header": "Test",
      "options": [
        { "label": "[detected]", "description": "Based on project files" },
        { "label": "pnpm test", "description": "pnpm package manager" },
        { "label": "npm test", "description": "npm package manager" },
        { "label": "go test ./...", "description": "Go testing" }
      ],
      "multiSelect": false
    },
    {
      "question": "What command checks types/lints?",
      "header": "Lint",
      "options": [
        { "label": "[detected]", "description": "Based on project files" },
        { "label": "pnpm lint", "description": "ESLint via pnpm" },
        { "label": "go vet ./...", "description": "Go vet" },
        { "label": "None", "description": "Skip linting" }
      ],
      "multiSelect": false
    },
    {
      "question": "What command builds the project?",
      "header": "Build",
      "options": [
        { "label": "[detected]", "description": "Based on project files" },
        { "label": "pnpm build", "description": "Build via pnpm" },
        { "label": "go build ./...", "description": "Go build" },
        { "label": "None", "description": "No build step" }
      ],
      "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.
