agent

Look for bugs and broken project rules in the changed code.

Called by
f-inspect
On site

Used as a reviewer inside f-inspect, the first end-of-job review.

When

In every end-of-job review; it always runs.

It's working if
  • It starts by saying what it reviewed: the job's range, a PR, or named files.
  • It reports only issues it rates 80 or above for confidence, grouped as Critical (90 to 100) and Important (80 to 89).
  • Each finding gives the file:line, the repo rule or the bug it breaks, and a concrete fix.
  • A finding rated 90 or above shows the snippet, the input that reaches it with the wrong outcome, and why existing guards miss it.
  • It says what it did not cover and why, and a clean diff gets zero findings, not invented ones.
  • It changed no code and moved no git state.
Common questions
Do I call it directly, or does /f-inspect run it?
In Topping Out, /f-inspect runs it on every lens inspection, as a fresh subagent with no context from the job. You can also run it on its own, for example before opening a PR.
Does it change code?
It is told not to: it reports only. Its tools are read and search, plus a shell it is told to use only for read-only git, so this rests on its instructions, not on a lock. Accepted findings become the builder's test-first repair work orders.
Does it give a verdict?
Only when run on its own: it then closes with APPROVE, WARNING or BLOCK. Under /f-inspect it is asked for findings only, with no verdict.
What does it check besides bugs?
The rules in the repo's own AGENTS.md or CLAUDE.md, code quality, and minimalism: whether an addition duplicates an existing helper or adds more than the task needed. It also keeps a list of house conventions that look like findings and are not.
Does it run on QUICK jobs?
No. QUICK jobs skip the lens inspection, and the record says so.
