impact-map

impact-map is a skill for Claude Code, Codex from morimorijap/sunaba-cli. It costs 0 tokens per session (68 once invoked), scanned A, original, MIT.

A pre-change assessment for estimating which files and existing code may be affected by a requested implementation.

In plain words
What is it for?
Use it before changing unfamiliar code to map files, symbols, scripts, risks, and a checkpoint for human review.
Why use it?
It exposes likely risks, reusable code, and unknowns before edits begin, helping people review the intended scope.

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

impact-map 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 1mo 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

impact-map

Use before implementation when the requested change touches code you have not edited in this session.

Output

  • Files likely to change.
  • Existing symbols / scripts to reuse.
  • Risks and unknowns.
  • A short checkpoint for human review.

Do not edit files in this skill. Return only the map.

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.
