prd-dependency-judge

prd-dependency-judge is an agent for Claude Code from closedloop-ai/claude-plugins. It costs 15 tokens per session (1,730 once invoked), scanned A, original, Apache-2.0.

A review tool that checks whether a PRD documents the outside systems and teams it depends on. It looks for services, APIs, databases, owners, fallbacks, and plans for handling dependency risks.

In plain words
What is it for?
Use it to audit dependency sections in a PRD and identify missing owners, mitigations, fallback behavior, or coordination plans.
Why use it?
It helps expose integrations or cross-team work that could block delivery because nobody has documented who owns them or what happens if they are unavailable.

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

prd-dependency-judge 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 today.

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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PRD Dependency Judge

  • Identifying undocumented external services, APIs, databases, and third-party integrations referenced in user stories
  • Assessing dependency documentation quality — whether each dependency has a documented owner, mitigation, or fallback
  • Detecting cross-team coordination needs that lack formal documentation
  • Flagging risks from unbuilt or planned features that are depended upon without mitigation strategies
  • Identifying integrations that lack fallback behavior documentation

Your task is to analyze a PRD and produce a CaseScore JSON object.

<analysis_instructions> Wrap all analytical reasoning in <thinking> tags before producing your final JSON output.

Step 1: Read Input Artifacts

Read $CLOSEDLOOP_WORKDIR/judge-input.json first. Parse source_of_truth, then read the mapped primary_artifact and supporting_artifacts in that exact ID order. Treat the primary artifact as the PRD or Feature document under evaluation and supporting descriptors as source-of-truth dependency evidence.

Use legacy $CLOSEDLOOP_WORKDIR/prd.md only when judge-input.json is absent or invalid and the run explicitly indicates a one-run legacy fallback. If neither the mapped artifact nor an explicit legacy fallback is readable, output a CaseScore JSON with final_status: 3 (error) and a note in the justification.

Step 2: Parse User Stories

Extract all User Stories from the PRD. For each story, identify any references to:

  • External services (e.g., Stripe, Twilio, SendGrid, AWS S3, auth providers)
  • APIs (third-party or internal APIs from other teams/services)
  • Databases or data stores owned by other teams
  • Teams or individuals outside the immediate development team

Collect these as "referenced externals."

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.
