Pastiche Sync

Pastiche — sync

Refresh FACT after the user's DS changes. Extractor regenerates pastiche/FACT.md; lint surfaces orphaned tags in KNOWLEDGE/WISDOM. The user remediates manually.

Preflight

1. Resolve repo root: git rev-parse --show-toplevel; on failure, fall back silently to cwd. Print: "Syncing /pastiche/FACT.md."
2. If /pastiche/config.yaml does not exist, stop:

> /pastiche/config.yaml not found. Run /pastiche-init first.

Extract FACT

Shell: extract-fact (cwd = `). It is on PATH via the plugin's bin/` — do not search for it. Block on completion.

On non-zero exit, print stderr verbatim and stop. Do not run lint — FACT may be stale or unwritten. The extractor's own message (config parse error, missing input file, etc.) is the actionable surface.

On success, the extractor prints "Wrote pastiche/FACT.md: components, tokens." to stdout. Forward it as-is.

Lint self-check

Shell: pastiche-lint (cwd = `). It is on PATH via the plugin's bin/` — do not search for it. Block on completion.

Forward stdout (summary) verbatim. If exit is non-zero, also forward stderr (violations) verbatim. No reformatting.

Classify the outcome by exit code + stdout shape:

• Clean — exit 0.
• Drift — non-zero exit, stdout summary present.
• Crash — non-zero exit, no stdout summary. The lint script itself broke; this is not user-visible drift.

Sync itself never exits non-zero on lint output. Carry the classification into Close.

Close

Print exactly one of:

Clean: > Pastiche synced. FACT.md regenerated; no drift detected. > > Run git diff pastiche/FACT.md to inspect changes.

Drift: > Pastiche synced — FACT.md regenerated, lint surfaced drift (see violations above). > > Remediate by editing pastiche/WISDOM.md / pastiche/KNOWLEDGE.md directly, or use /pastiche-write-wisdom / /pastiche-write-knowledge to add or replace rules. Run git diff pastiche/FACT.md to inspect the FACT changes that triggered the drift.

Crash: > Pastiche synced. FACT.md was regenerated successfully, but the lint script crashed unexpectedly (output above). Report this to the pastiche maintainers. > > Run git diff pastiche/FACT.md to inspect changes.

Do not invoke another skill. Do not suggest /pastiche-setup — it is curation, not remediation.
