cold-start

cold-start is a skill for Claude Code, Codex from kunalsuri/ai-fication-kit. It costs 64 tokens per session (1,134 once invoked), scanned A, original, Apache-2.0.

A repository onboarding procedure that creates a draft map of the codebase and supporting guide documents when the project has no reliable knowledge layer.

In plain words
What is it for?
Use it to draft module maps, architecture diagrams, project overviews, and guide documents from repository facts and existing configuration.
Why use it?
It gives a human reviewer an initial understanding of the repository while marking uncertain information as inferred. It does not alter source code.

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

cold-start 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 7d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cold-start the knowledge layer

The contract: read-and-write-docs-only — touch no source code, tag everything [inferred], and stop at an AUDIT TODO for the human. You draft the map; a human verifies it before any feature is built.

1. Load the facts

Read ai/repo-profile.json (deterministic output of the kit's orient step). Treat its stack facts as given; VERIFY its build/test commands against the real config files before writing them anywhere as confirmed. If the profile says this repo is a fork, separating OUR code from FROZEN upstream code is the single most important output of this pass. If a humanContext block is present, use it: developer.skillLevel/codebaseFamiliarity calibrate how conservative your Stability guesses are; stack.kind tells you whether to map a frontend/backend split; record branch/firstRunAt in PROJECT_OVERVIEW.md.

2. Absorb prior config (Process 2 repos only)

If repo-profile.jsonmaturity.process is 2, CLAUDE_bkp_*.md / AGENTS_bkp_*.md exist at the repo root with the team's previous AI configuration. Read them, extract KNOWLEDGE — not raw text — (build commands, conventions, architecture notes, gotchas, module descriptions) and merge it into ai/guide/CONVENTIONS.md, ai/guide/ARCHITECTURE.md, ai/guide/MODULE_MAP.md (seed rows), and ai/guide/PROJECT_OVERVIEW.md. Tag every extract [inferred — from prior config].

3. Explore cheaply, read-only

List the tree 2 levels deep, read build manifests (not source), scan the last ~30 commit subjects for active areas. Prefer grep + line counts over whole-file reads. Modify nothing in this step.

4. Fill MODULE_MAP

ai/guide/MODULE_MAP.md: one row per module/package — directory, a one-line responsibility, the entry-point file, and a Stability GUESS. Use the ACTUAL names you found; do not assume names. Each row has FIVE cells — Directory, Responsibility, Entry point, Stability guess, Status — and the Status cell is where the [inferred] tag goes (the tooling reads provenance from the LAST cell only).

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.
