eng-design-doc-review

eng-design-doc-review is a skill for Claude Code, Codex from bostonaholic/team. It costs 42 tokens per session (1,889 once invoked), scanned A, original, MIT.

A fresh-context review of a technical design document, which describes how a planned system or change should work. It asks an independent read-only reviewer to return APPROVE, REQUEST CHANGES, or COMMENT.

In plain words
What is it for?
Use it to audit documents in docs/plans/ or design.md before implementation, especially when you want an independent check of the plan.
Why use it?
It reduces the risk that the document's author overlooks flaws or approves their own assumptions. The reviewer cannot edit the design, so the assessment stays separate from the writing.

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

eng-design-doc-review 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 6d 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.

Engineering Design Doc Review — Independent Fresh-Context Audit

Adversarially review a design document with fresh context. The brief this skill dispatches lives in skills/reviewing-designs/SKILL.md, and the orchestrator loads the same brief for the DESIGN phase's adversarial review gate. Invoking this skill standalone remains supported whenever you want an independent, fresh-context audit of a design document.

Write the prose this skill governs at a seventh-grade reading level, in STE-flavored mode — short sentences, common words, no unexplained jargon. Full methodology: writing-prose. Before you finalize prose this skill governs, call the Skill tool with writing-prose and apply its ## Self-lint checklist.

There is no custom review agent. This skill loads the review brief from reviewing-designs and dispatches the built-in read-only Explore subagent through the Agent tool. That subagent boots with a clean context and no shared conversation history with the design-author — that isolation is the whole point. It prevents self-evaluation bias. Explore holds no Write/Edit tools, so the reviewer structurally cannot change the artifacts it judges. Fresh context plus veto-without-authorship is the generator-evaluator rule (principle-generator-evaluator).

Input

$ARGUMENTS is the artifact directory: docs/plans/<id>/. If empty, the discovery command below resolves it.

The review reads:

  • $ARGUMENTS/6-design.md — the document under review (required)
  • $ARGUMENTS/1-task.md, $ARGUMENTS/2-questions.md, $ARGUMENTS/5-research.md, $ARGUMENTS/4-repos.md — predecessor artifacts (read for grounding when present, missing siblings are not a hard error)

Resolve <team-skill-dir> to the absolute directory containing skills/team/SKILL.md. From the repository root, run:

"<team-skill-dir>/discover-topic.sh" "${ARGUMENTS:-}" "6-design.md"
  • If the command printed a path, use it as $ARGUMENTS for the rest of this skill. That is tier 1 explicit arg, or tier 2 discovery. When the path came from tier 2, with no explicit arg, announce the resolved directory to the user first. An auto-picked topic is then never silent.
  • If the command printed nothing (tier 3 — no directory holds 6-design.md), do not hard-error. Fire AskUserQuestion with a Setup header and labeled options:
    • Run the producer — run /team-design docs/plans/<id>/ to produce the missing 6-design.md.
    • Give a path — the user supplies the docs/plans/<id>/ directory directly (run ls docs/plans/ to find your topic directory).

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.
