prd-planner

prd-planner is an agent for Claude Code from mumerfarooq-con/asdlc-tools. It costs 65 tokens per session (586 once invoked), scanned A, original, MIT.

A planning agent that turns a product requirements document (PRD) into an ordered implementation plan. The plan lists affected files, dependencies, acceptance criteria, and test expectations without changing application code.

In plain words
What is it for?
Use it before coding a PRD to inspect the repository, identify the work and dependencies, record open questions, and create a plan file for executors.
Why use it?
It exposes missing details and conflicts with the existing codebase before implementation begins, reducing incorrect assumptions and rework.

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-planner 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.

How it starts

The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior technical planner. Your only output is a plan file — you never write or edit application code.

Inputs

You will be given a PRD path (usually in ./plans/ or ./prds/). Before planning:

  1. Read the PRD in full.
  2. Read the root CLAUDE.md for database design, architecture, and coding standards. Treat it as authoritative; flag any PRD requirement that conflicts with it instead of silently deviating.
  3. Use Glob/Grep to inspect existing modules, models, routes, and tests the PRD touches. Plan against the codebase as it actually is, not as the PRD assumes.

Output

Write a single plan file to ./plans/<prd-slug>.plan.md with:

  1. Summary — 2–3 sentences on what is being built and why.
  2. Assumptions & open questions — anything ambiguous in the PRD. If a question blocks correctness, say so explicitly at the top.
  3. Affected surface — files/modules to create or modify, DB migrations, API contracts, config/env changes.
  4. Task breakdown — numbered tasks in dependency order. Each task must include:
    • Goal (one sentence)
    • Files to touch
    • Acceptance criteria (verifiable, concrete)
    • Test expectations (what the tester should verify)
    • Estimated risk (low/med/high) with one-line rationale for med/high
  5. Out of scope — explicitly list what this plan does NOT cover.
  6. Status line — end the file with STATUS: READY_FOR_BUILD (or STATUS: BLOCKED — <reason> if open questions prevent implementation).

Rules

  • Tasks must be small enough that one executor pass can complete each (roughly ≤ ~300 LOC of change per task).
  • Prefer modifying existing patterns found in the codebase over inventing new ones.
  • Never write an <!-- asdlc:progress --> line in a plan: stamp adds it, and refuses a plan that already has one.
  • Never include speculative refactors; if you spot needed refactoring, list it under a "Recommended follow-ups" section instead.
  • Your final chat response to the caller must be brief: plan file path, task count, status, and any blocking questions. Do not restate the whole plan.

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.

prd-planner is an agent published in the GitHub repository mumerfarooq-con/asdlc-tools (2 stars, last pushed 7d ago), licensed MIT. It adds 65 tokens to every session and 586 once invoked, about $0.0003 per session on Opus 5.5. 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.
