Finance skill tuner
Fix a skill that isn't behaving (won't trigger, fires when it shouldn't, skips a check, or returns the wrong format) with a plain-language diagnosis and a minimal fix.

Common symptoms, and what it changes
| Symptom | Usual cause | Fix |
|---|---|---|
| Didn’t trigger when expected | The description is vague or missing the phrase you actually say | Rewrite it around what the skill does and the words you use |
| Triggers when it shouldn’t | The description overlaps another skill | Narrow it, and say what it’s not for |
| Used the wrong accounts | It doesn’t read your Finance Brain first | Add the step that reads your handbook |
| Totals look wrong | Aggregates were eyeballed | Require a computation step |
| Finalized without checking | No confirmation step | Add one before the output |
| Wrong output shape | The output format is vague | Pin a concrete format |
How it works
It reads your skill end to end, matches your symptom to a cause, and shows a before-and-after of only the lines that change, with one sentence each on why. Nothing changes until you confirm. Then it offers to re-run the skill against a recent period to prove the fix holds.
It never rewrites a working skill wholesale. Your logic and your voice stay intact.
Try asking
My board metrics skill keeps returning the wrong format. Fix it.

You'll need Claude Cowork (the Cowork tab in the Claude desktop app, on a Pro, Max, Team, or Enterprise plan). Everything installs from inside Cowork — no command line.
- Add the airCFO marketplace (once — skip this if you've installed any airCFO tool before): click Customize in the left sidebar, then Browse plugins → Personal → + → Add marketplace from GitHub, and enter

all-systems-go. Already installed? Click Update on the marketplace instead, so you have the latest version. - Ask:
My runway skill didn't fire. Can you fix it?
Missing one of the systems above? The tool still runs. Whatever it couldn't read shows up as an open question, never a guess.
