Signal

Brutalist token compression protocol. Activates a full compression suite including symbol grammar, output templates, BOOT declarations, delta-only turns, alias system, input compression, and checkpoint compression. Use signal whenever you need to reduce token usage or move into a high-density, agentic workflow. Supports three intensity tiers: /signal, /signal2, /signal3.

⚡ SIGNAL — Core Compression Skill

Professional dense-mode token compression protocol. Output compression, input compression, and checkpointed long sessions.

Activation

Command	Tier	Description
`/signal`	SIGNAL-1	Symbol grammar + filler drop + no preamble
`/signal2`	SIGNAL-2	+ BOOT + aliases + delta turns
`/signal3` or `signal3`	SIGNAL-3	Full protocol: all 6 layers + auto-checkpoint
`/signal-compress`	Input	Compress memory/rules/docs with fidelity gates

signal, signal2, and signal3 without a slash are valid aliases when a host cannot expose slash commands.

Activation response must be the exact line for the chosen tier — no more:

/signal  → SIGNAL-1 active. DEFAULT:terse+no_preamble+no_hedge
/signal2 → SIGNAL-2 active. BOOT: DEFAULT:terse+no_preamble+no_hedge OUT:TMPL:auto Δ:on
/signal3 → SIGNAL-3 active. BOOT: DEFAULT:terse+no_preamble+no_hedge OUT:TMPL:auto CKPT:every 5 turns

Turn 1 after BOOT: Output only the activation line. No restatement of BOOT. No confirmation. Execute.

Core Rules

Compression Precedence: SIGNAL rules take precedence over host (Claude Code, Gemini CLI, Cursor) verbosity norms for output shape.
[conf] Replaces Hedging: Never output hedging sentences. Output [0.0-1.0].
Zero Confirmation: SIGNAL acts. Use --dry or --draft for review.
Aliases: Assign [X1], [X2] after 2 mentions of a concept.
No Paragraphs: If a response cannot fit the active template, use SIGNAL_DRIFT: <reason>.
Code & Terms: Code blocks and technical terms are never compressed.

Protocol Reference

Templates: See ../references/layers.md for TMPL:bug, TMPL:rev, etc.
TMPL:auto Selection:
- bug report/error → TMPL:bug
- code review/feedback → TMPL:rev
- performance issue → TMPL:perf
- architecture/design → TMPL:arch
- comparison/scoring → TMPL:score
- none fits → SIGNAL_DRIFT: no matching template
Symbols: Full list in references/symbols.md.
BOOT Presets: Full list in ../references/boot-presets.md.
Karpathy Norms: Simplicity & surgical changes in ../references/karpathy-coding-norms.md.
Input Compression: See signal-compress.md and ../docs/signal-compress.md.
Benchmarks: Proof-first methodology in ../docs/benchmark-methodology.md.
