post-cold-start-verification

post-cold-start-verification is a skill for Claude Code from kunalsuri/ai-fication-kit. It costs 32 tokens per session (502 once invoked), scanned A, original, Apache-2.0.

A read-only audit procedure for an AI knowledge layer, meaning the project files that explain how an AI coding agent should work. It checks those files for placeholders, stale information, inconsistent references, and mismatched project instructions, with permission to write one report.

In plain words
What is it for?
Inspect files under ai/ and entry files such as CLAUDE.md and AGENTS.md for unfinished markers, invalid paths, incorrect module maps, outdated commands, and inconsistent profiles. Use an existing verification manifest when available and produce a prioritized findings report.
Why use it?
Documentation can drift away from the code after changes or when a project is reopened after a long pause. The audit separates mechanical path checks from issues that require human judgment about meaning and consistency.

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

post-cold-start-verification 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 9d 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.

What it actually says

Audit the AI knowledge layer. Read-only with one exception: you may write ONE report.

Step 0 — use the mechanical verifier's output, don't redo its job

If ai/analysis/audit-reports/VERIFICATION_MANIFEST.json exists, read its summary and the non-confirmed claims first: path-existence checking is already done deterministically by the kit's verify command (run from the kit checkout: node install.mjs verify <repo> — no LLM involved, so its statuses are facts). Spend your pass on what a script cannot judge (checks 1, 3, 4 below, and the semantic half of check 2). If the manifest is absent or older than the docs it covers, recommend regenerating it in your report instead of re-deriving path checks by hand.

Checks

  1. Placeholders: find every <fill in>, ? Stability, and {{...}} leftover across ai/ and the entry files (CLAUDE.md, AGENTS.md).
  2. Internal consistency: every path mentioned in ai/guide/* exists on disk (covered by the manifest when present — see Step 0); MODULE_MAP rows correspond to real directories; FEATURE_MAP entries point at real files; diagrams name real modules.
  3. Profile consistency: build/test commands in CLAUDE.md/AGENTS.md match ai/repo-profile.json; flag divergence (don't silently fix).
  4. Provenance hygiene: no [verified] tag lacking a date; nothing you can tell was agent-written carrying [verified].

Output

Write ai/analysis/audit-reports/<YYYY-MM-DD>-post-cold-start.md: findings grouped P1 (agent-blocking) / P2 (misleading) / P3 (cosmetic), each with location and a one-line suggested fix. Tag the report itself [inferred]. Do not modify the files you are auditing.

Changes

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.
