differential-audit

differential-audit is a command for coding agents from jszmajda/lid. It costs 77 tokens per session (210 once invoked), scanned A, original, MIT.

A command for checking whether EARS requirements, a structured way to write software requirements, match the code in both directions.

In plain words
What is it for?
Use it to scope or run a bidirectional audit for selected EARS IDs and related project arrows.
Why use it?
It can reveal requirements that the code does not implement and code behavior that the requirements do not describe.

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

differential-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 5d 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

Invoke the bidirectional-differential skill in command mode.

  • /differential-audit — opens the scoping conversation (interprets the user's description, maps to arrows, captures scope and runs-per-direction, confirms with a cost estimate).
  • /differential-audit EXP-BIDIFF-001 KWP-UE-004 — audits the listed EARS IDs directly using defaults from CLAUDE.md's ## LID Experimental section (default N=3).

See plugins/lid-experimental/skills/bidirectional-differential/SKILL.md for the full behavior.

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.
