- # Compact Communication Contract

- Apply Caveman-inspired compression to runtime communication only. Keep technical substance. Remove filler.

- ## Default Rules

- - Lead with outcome, verdict, or delta.

- - Prefer short sentences, fragments, and flat bullets.

- - Report only changed state, counts, blockers, and next action.

- - Do not restate workflow steps unless status changed.

- - Keep file paths, requirement IDs, task IDs, commands, URLs, headings, and markers exact.

- - Keep fenced code blocks and inline code exact.

- - When a machine-readable contract exists (JSON, table schema, checklist grammar), obey it exactly and add no extra prose.

- ## Preferred Output Patterns

- - Progress update: done, issue, next.

- - Validation or audit: PASS/FAIL first, then only failing or risky items.

- - Research: recommendation, avoid, sources.

- - Review finding: location, severity, problem, fix.

- - Summary: counts, deltas, blockers, next step.

- ## Auto-Clarity

- Drop compression and use normal explicit prose when brevity could create ambiguity for:

- - security warnings

- - destructive or irreversible actions

- - ordered multi-step instructions

- - user questions showing confusion or repetition

- - policy, compliance, or safety-sensitive nuance

+ # Compact Communication Contract — DEPRECATED

- Resume compact mode after the risky section is clear.

+ The runtime communication contract (default rules, preferred output patterns, auto-clarity exceptions, and exact-preservation boundaries) now lives in `AGENTS.md` under `## Communication Style`. That section is loaded once per command as ambient context; no skill or sub-agent should `Read` this file.

- ## Boundaries

+ This shim is kept so existing external references to the path do not break. The `scripts/drift-report.mjs` strict check fails any PR that re-introduces a `Read .github/skills/compact-communication/SKILL.md` instruction outside this file.

- - Never compress or mutate artifact grammars, IDs, checkbox state, or required section headers.

- - For parser-sensitive files under `specs/`, write concise normal prose; do not rewrite them into stylized shorthand.

- - Readability beats maximum compression for persisted artifacts.

- - For allowlisted narrative Markdown, prefer validator-backed compression via `.github/skills/markdown-compression/SKILL.md` instead of ad hoc rewrites.
