Compact Agent Skills for repeated runtime efficiency without silently changing activation, behavior, safety, output, or validation contracts.

Core Execution Contract

Follow this loop for every compaction. Do not require a reference file to carry these steps.

1. Establish the target, optimization surface, mode, allowed loss, and writable scope. If the user supplied them clearly, proceed without another question.
2. Extract the source contract and a typed structured inventory.
3. Make a placement map: keep, move, rewrite, delete, split, or no change.
4. Change only the authorized target and preserve the selected mode's contract.
5. Re-extract the inventory from the result and compare it with the source.
6. Repair critical regressions, then report measured change and validation.

The source contract includes:

• activation and non-activation boundaries
• inputs, outputs, required order, conditions, and postconditions
• commands, paths, IDs, URLs, code/config/API examples, and concrete evidence
• prohibitions, exceptions, fallbacks, safety rules, and human confirmations
• validation steps, expected results, references, and output contracts

Treat any missing critical item as a regression unless the user explicitly accepted that loss.

Mode And Loss Boundary

• conservative is the default. Preserve all critical inventory and ambiguous source-specific meaning. Prefer local deduplication or moving long material with a direct route over deletion.
• structural applies only when the user wants stronger compaction while retaining explicit lists, steps, criteria, and operational structure.
• summary applies only when the user requests summary-like compression or accepts lower reconstruction fidelity. Never weaken activation, safety, required validation, or output contracts silently.
• no change is valid when the target is already compact or when added references and maintenance cost would outweigh the reduction.
