A clean composition view of how categories shift across snapshots, built for non-financial data. This one is newer — the trigger wording is still being confirmed on real use, so treat the output shape as provisional.
The generalised discipline (provisional — this skill is new):
Confirm the skill actually fires — in your own session, on your own data. No data leaves your machine.
Does it fire? Paste the prompt in demo-input.md. You should get the shape shown in expected-output.md.
On your data. Run it on your real input.
Confirm the shape. Save the output to a file and run:
node ${CLAUDE_SKILL_DIR}/scripts/check.mjs <your-output-file>
It reports ENGAGED when the output carries this skill's characteristic structure — the deterministic sign it fired. It checks shape, not quality; judge the content yourself.
The check runs entirely locally — nothing leaves your machine. If you want to add to the public "confirmed working" count, opt in explicitly:
node ${CLAUDE_SKILL_DIR}/scripts/check.mjs <your-output-file> --report https://skills-field-guide-proxy.nesper6311.workers.dev --skill composition-snapshot
That sends only an anonymous +1 — never your input, output, or identity.
Installed from the public field guide. Customize freely — this is a starting point built from the published projection of composition-snapshot.
Creates, edits, and optimizes skills for Claude Code, including drafting, evaluating with test prompts, iterating on performance, and improving skill descriptions for better triggering accuracy.
