compatibility-audit

compatibility-audit is a command for coding agents from ivklgn/ai-kit. It costs 20 tokens per session (129 once invoked), scanned A, original, MIT.

A command that reviews a code change or selected code area for compatibility with its users, surrounding code, and runtime environment. Compatibility means checking that the change fits the systems that depend on it.

In plain words
What is it for?
Use it to audit current Git changes, a package, module, class, file, schema, or configuration. You can also specify a different Git reference as the comparison baseline.
Why use it?
It can expose problems where a change works in isolation but breaks callers, related modules, configuration, or the target runtime. This helps identify integration issues before merging or releasing changes.

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

compatibility-audit 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 3d 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.

Arguments

The user invoked this command with: $ARGUMENTS

Interpret the arguments as the audit scope:

  • empty — audit the current git changes against the merge base
  • a path — audit that package, module, class, file, schema, or config
  • --base <ref> — use that ref as the baseline instead of the detected merge base

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.
