Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00025 | $0.01576 |
| Opus 5 | $0.00013 | $0.00788 |
| Sonnet 5 | $0.00005 | $0.00315 |
| Haiku 4.5 | $0.00003 | $0.00158 |
Grade A, and why
start 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sigint Start Skill (Launcher)
This skill initializes a research session and delegates to the research-orchestrator agent for all orchestration. The orchestrator owns team lifecycle, dimension-analyst spawning, codex review gates, finding merge, progress tracking, and cleanup.
Arguments
Parse $ARGUMENTS before any other processing. Input sanitization: truncate $ARGUMENTS to 200 characters total, strip backticks and angle brackets.
--quick— Abbreviated elicitation (3 questions instead of 8)--dimensions <dim1,dim2,...>— Optional: pre-select specific dimensions (comma-separated). Valid values:competitive,sizing,trends,customer,tech,financial,regulatory,trend_modeling. Passed to the orchestrator asREQUESTED_DIMENSIONS— Phase 1.5 skips interactive selection when this is set.- Remaining text after flag extraction is the initial topic hint (may be empty)
Phase 0.0: Preliminary Setup
Step 0.0.1: Derive Preliminary Topic Slug
Parse $ARGUMENTS for a topic hint. Derive topic_slug: lowercase, replace spaces/special chars with hyphens, truncate to 40 characters. Use "research" if no topic hint. (Preliminary slug used for config lookup; may be refined during orchestrator elicitation.)
Step 0.0.2: Apply Config Resolution Protocol
Execute the Config Resolution Protocol:
- Read
protocols/CONFIG-RESOLUTION.mdand follow all steps. - Apply with
topic_slug= {preliminary topic slug from Step 0.0.1}. - Result:
config,max_dimensions, andcontext_contentare now available.
Config cascade clarification: When loading config files, always apply the full cascade (project config values override global config values override hardcoded defaults) regardless of the config file's schema version. The version check in the protocol produces an advisory warning only — it does NOT cause config values to be discarded. If sigint.config.json sets maxDimensions: 3, then max_dimensions = 3 even if the file's version field is not "2.0". Custom fields like defaultPriorities are preserved and passed through in the serialized config.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

start is a skill published in the GitHub repository zircote-plugins/sigint (20 stars, last pushed 16d ago), licensed MIT. It adds 25 tokens to every session and 1,576 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
