stoa: Skill for Claude Code

.claude/skills/council/SKILL.md

council is a skill for Claude Code from stoa-platform/stoa. It costs 31 tokens per session (4,707 once invoked), scanned A, original, Apache-2.0.

A review workflow that asks eight different reviewer roles to assess a feature or architecture decision record, then can create a Linear task when the score is high enough. An architecture decision record is a document explaining an important technical choice.

In plain words
What is it for?
Checking whether a ticket is worthwhile, validating a plan, scoring proposed changes, and reviewing implementation stages through the related scripts and checks.
Why use it?
It adds a structured challenge before implementation and connects an approved proposal to a tracked task.

This is stoa-platform/stoa's own configuration. It tells Claude Code how to work on stoa itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything stoa configures →

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

council 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 2mo 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.

Council Validation — $ARGUMENTS

Three-Stage Council

This skill drives Stage 1 (ticket pertinence) and Stage 2 (plan validation) — both prose-based, 8-persona scoring per the canonical Team Coca jury (HEG-PAT-003).

Stage 3 (code review) runs after implementation on the actual diff, via scripts/council-review.sh (4-axis: conformance, debt, attack_surface, contract_impact). It is not invoked by this skill — it is wired to the pre-push hook (CAB-2048) and council-gate.yml CI workflow (CAB-2049). See .claude/docs/council-s3.md for full docs.

S1 (this skill, prose)  →  S2 (this skill, plan)  →  implementation  →  S3 (council-review.sh, diff)  →  merge

Step 1: Gather Context

Read and understand the feature/ADR/change description. Gather context from:

  • memory.md — current sprint, related work
  • plan.md — where this fits in priorities
  • Relevant code files if technical

Step 1b: Context Compiler — Impact Score

Run the Context Compiler to get the blast radius before scoring:

  1. Determine the primary component from $ARGUMENTS (or from the ticket description if CAB-XXXX is provided)
  2. Run: docs/scripts/build-context.sh --component <component> --intent "$ARGUMENTS"
    • If a ticket ID is available: add --ticket "CAB-XXXX"
  3. Read the generated context pack in docs/context-packs/
  4. Extract the Impact Score and level (LOW/MEDIUM/HIGH/CRITICAL)
  5. Include the Impact Score in each persona's evaluation context
  6. If CRITICAL (>= 31): flag it explicitly in the Council report header

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.
