Tighten File

Tighten File

Apply tighten-instruction at three levels: whole file, section, instruction.

Steps

Step 0 — Load

Invoke the tighten-instruction skill via the Skill tool. This file-level workflow owns the apply gate.

Step 1 — Pin meaning

State the file's purpose in one line. List every distinct instruction or fact that must survive, including exact tokens, anchors, output contracts, and load-bearing rationale.

Step 2 — Find and score edits

Apply the loaded lens at whole-file, section, and instruction level. For each independent edit, record:

• the current text;
• the proposed text, or cut entirely;
• the level: whole-file, section, or instruction;
• confidence 0.00–1.00 that the edit improves clarity without changing meaning.

Keep load-bearing rationale. When a reason is the non-derivable fact, shape it as behaviour — constraint; do not cut it as explanation.

Step 3 — Gate and apply

Show the plan, then:

• apply every edit at c ≥ 0.75;
• hold lower-confidence proposals and leave their text unchanged;
• apply whole-file and section edits before instruction edits;
• drop any later proposal an applied edit dissolves.

**Tightening plan — <file>:**
- [0.92] section: <current> → <proposed>
- [0.61] instruction: <current> → <proposed> · held (< 0.75)

Write Nothing to tighten — already clear. when no edit qualifies.

Step 4 — Prove and report

Re-read the changed file cold. Confirm:

• every Step 1 invariant survived;
• every exact token and anchor remains valid;
• every cross-reference still resolves;
• no rationale lost its constraint.

Revert or fix any edit that fails this proof.

Report applied edits, held proposals, dissolved proposals, and net clauses, lines, and words removed.
