signal

signal is a skill for Claude Code, Codex from SijuEC/eridani-speak. It costs 30 tokens per session (287 once invoked), scanned A, original, MIT.

A response style that removes filler, extra articles, and hedging so language models return short, information-dense answers. It can be switched on with #signalon and off with #signaloff.

In plain words
What is it for?
Use it for compact explanations, code-related answers, commands, file paths, error messages, and other technical output.
Why use it?
It makes responses quicker to scan and easier to use in coding pipelines where concise output matters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

signal scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
