What its author says it does
Copied from the file, not written here
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
--dryor--draftfor 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.
