Trim

Shrink an always-on context file that has gotten too big. /trim <file> walks the reduction, safest cuts first, never dropping a rule.

Workflow Routing

Trigger	Workflow
`/trim <file>`, "trim OPERATIONAL_RULES", "this file is too big", "reduce a doctrine file", "fold the proposal inbox"	`Workflows/Trim.md`

Target resolution: a bare name (OPERATIONAL_RULES) resolves against the always-on set — the system prompt, CLAUDE.md, its @-imports, and the hook-injected memory files. No arg → wc -c that set and take the largest.
Order is safest-first: (1) show state, (2) deterministic GC (zero-risk), (3) semantic trims (human-gated), (4) safety gate, (5) re-measure. Full steps: Workflows/Trim.md.
One tool it orchestrates — never reimplement: LIFEOS/TOOLS/ProposalGC.ts (removes superseded/duplicate/absorbed entries). Sizes come from wc -c.
Three semantic moves: MERGE overlapping rules, TIGHTEN verbose ones, RELOCATE rarely-used detail to an on-demand reference (leave a stub + pointer).
The invariant: a trim never drops a distinct directive. If a merge would, keep the original.
