BF file-access-preflight
Run the pre-flight checklist before an agent gets filesystem access — the scope boundary (which directories, read vs write), the secrets-exposure sweep, the destructive-operation gates, and the path-traversal and untrusted-file defenses. Use when asked let my agent access my files safely, is it safe to give the agent file/computer access, guardrails before the agent touches my filesystem, or scope down my coding agent's reach. Produces the scope boundary, the secrets sweep, the write/delete gates, and the untrusted-content rules.

How to improve
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- 30Running it twice. 10 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 55Failures and branches. 1 branches
- 60Result and completion. Output format stated, no completion criterion
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 23 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1520 tokens
- 100Progress reporting. Reports progress
- low 11 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
