Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01286 |
| Opus 5 | $0.00018 | $0.00643 |
| Sonnet 5 | $0.00007 | $0.00257 |
| Haiku 4.5 | $0.00004 | $0.00129 |
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.
How it starts
The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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/bungo.mod→ GoCargo.toml→ Rustpyproject.toml/requirements.txt→ PythonMakefile→ 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 ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 10d ago First seen · 195 lines · 37 tokens per session scan A 3b7287e99767
cog-init is a skill published in the GitHub repository MereWhiplash/engram-cogitator (4 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 1,286 once invoked, about $0.0002 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.
