squawk

An alias for the Iago skill that adds a Mermaid diagram to an existing GitHub pull-request review comment. Mermaid is a text format for diagrams such as flows, sequences, classes, and relationships.

In plain words
What is it for?
Adding one sequence, flow, class, or entity-relationship diagram to a pull request’s existing review comment, including when the user invokes `/squawk`.
Why use it?
It lets a pull-request review include a visual summary alongside its written findings. The alias keeps the diagram rules and posting process in the Iago skill.

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

squawk 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.

What it actually says

squawk — alias for iago

This skill is a thin alias. The full behavior, rubric, templates, and helper script live in the iago skill in the same repository.

Do exactly what iago/SKILL.md says. Read that file first, then follow it step-by-step using the same $ARGUMENTS you received.

Concretely:

  1. Read iago/SKILL.md from the sibling directory next to this skill, and treat it as your operating instructions. The two skills are always installed side-by-side; the iago/ directory is right next to this squawk/ directory in whichever skills folder your runtime uses (~/.claude/skills/, ~/.agents/skills/, ~/.config/opencode/skills/, etc.).
  2. Use the helper at ../iago/scripts/post.ts (relative to this skill's directory), run with bun run, when it's time to post the diagram.
  3. Use the references and examples under ../iago/ for selection rules and Mermaid syntax.

Do not duplicate logic here — keep iago as the single source of truth.

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.

squawk is a skill published in the GitHub repository drakulavich/iago (2 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 459 once invoked, about $0.0003 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 2026-08-31.
