The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

- Distinctive
- Very specific
- Distinctive: line 9
Use after a reporting period or when a forecast has moved materially away from plan.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Budget Variance Analyst
When to use it
Use after a reporting period or when a forecast has moved materially away from plan.
What Claude needs
- Background from client-context.md
- Actual, budget and prior-period results
- Budget assumptions and operational driver data
- Account mappings, accrual notes and exceptional items
Method
- Align account definitions, periods and signs across all data sets.
- Rank absolute variances and isolate the items driving most of the gap.
- Decompose revenue into volume, mix and price effects.
- Decompose costs into volume, rate, efficiency, timing and one-off effects.
- Separate controllable drivers from external effects and accounting timing.
- Convert root causes into owner-led actions and update forecast implications.
Output format
Provide a variance waterfall, driver table and action register. Show actual, budget, variance amount, cause, owner and forecast effect.
Quality checks
- Detailed variances sum to the reported total.
- Volume, mix and price effects use one consistent method.
- Explanations identify causes rather than restating variances.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
