At a glance
Compress LLM responses to pure signal — Rocky's early notation style.
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Signal is an agent skill from SijuEC/eridani-speak. Compress LLM responses to pure signal — Rocky's early notation style. Drop articles, filler, hedging. Best for pipelines and coding.
Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Token compression library inspired by a friendly alien engineer's communication style. The licence is MIT.
Example prompts
- “/signal”
What it can do on your machine
Read from SKILL.md and the folder at commit 82665d3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Signal loads about 304 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 143 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Compress LLM responses to pure signal — Rocky's early notation style. Drop articles, filler, hedging. Best for pipelines and coding.
Activate on: #signalon Deactivate on: #signaloff When deactivated: respond normally until reactivated.
When active, respond in this style.
Drop: articles, filler words, pleasantries, hedging. Fragments fine. Short synonyms. Technical terms exact. Code blocks, inline code, URLs, file paths, CLI commands, version numbers, error messages, stack traces, and technical names unchanged.
Notation: X = Y (definition) X → Y (causes / leads to) X: a, b, c (properties) Fix: ... (solution) Note: ... (important caveat)
Pattern: [thing] [action/state] [reason]. [next step].
EXAMPLES: User: How does indexing work? You: Index = pointer to data. Query → index first → table. Fast fast fast.
User: Should I use Redis or Postgres? You: Depends on need. Redis: fast, volatile. Postgres: slow, permanent. What data lives longest? Question?
User: My API calls keep timing out. You: Timeout = connection or response limit hit. Check: network latency, server load, timeout config. Fix: raise timeout value or optimize endpoint.

How do I install Signal in Claude Code?
Run `npx skills add SijuEC/eridani-speak --skill signal -a claude-code`. Or copy the skill folder (signal in SijuEC/eridani-speak) into .claude/skills/signal in your project. Claude Code loads it when a task matches its description.
How do I install Signal in Codex?
Run `npx skills add SijuEC/eridani-speak --skill signal -a codex`. Or copy the skill folder (signal in SijuEC/eridani-speak) into .agents/skills/signal in your project. Codex loads it when a task matches its description.
Can I use Signal in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add SijuEC/eridani-speak --skill signal -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/signal, .gemini/skills/signal, .github/skills/signal and .opencode/skills/signal in your project.
What does Signal need to run?
SKILL.md names no scripts, command-line tools or credentials: Signal is instructions for the agent only.
Does Signal access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Signal safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Signal use?
Signal is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Signal use?
About 304 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Signal?
Skills that share tags, products or a category with Signal: Compression (thedaviddias/Front-End-Checklist, 74k stars), Responsive Units (thedaviddias/Front-End-Checklist, 74k stars), Signals (PostHog/posthog, 40k stars) and Responsive Design (wshobson/agents, 40k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Signal?
SijuEC (a GitHub user) maintains it in SijuEC/eridani-speak, which has 100 GitHub stars. The repository holds 2 skills in this directory. The repository was last updated on April 22, 2026.
