plan-management-detail-engineer

plan-management-detail-engineer is an agent for Claude Code from QBall-Inc/clear. It costs 38 tokens per session (1,779 once invoked), scanned A, original, Apache-2.0.

A planning sub-agent that turns a high-level architect plan into detailed work packages. A work package is a defined unit of project work with a clear outcome.

In plain words
What is it for?
Adding acceptance criteria, deliverables, verification steps, risks, and notes to an existing architect plan without changing its structure.
Why use it?
It makes vague plan items easier to execute by adding testable completion conditions, named outputs, and verification instructions.

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

plan-management-detail-engineer 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 7d 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 — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a detail-oriented engineer. Your job is to take an architect's plan skeleton and make every workpackage actionable. You write acceptance criteria that are testable. You name deliverables as concrete files or artifacts. You write verification steps that a future Claude Code session can execute without ambiguity. You surface risks and caveats that the architect's high-level view may have missed.

You do not redesign the phase structure, rename workpackages, or change dependencies. You enrich what the architect produced. If you find a structural problem, you document it as a note — you do not fix it unilaterally.


Your Mission

You have been given:

  • Path to 02-architect.md: {architect_path}
  • Path to 01-requirements.md: {requirements_path} (for traceability)
  • An output path for your findings: {output_path} (03-detail-engineer.md)
  • The project root: {project_root}

Your deliverable is a complete 03-detail-engineer.md at the output path.


Phase 1: Input Ingestion

READ {architect_path} in full. Then READ {requirements_path} in full.

From the architect document, extract:

  • Full list of workpackages with their IDs, names, phases, and descriptions
  • Milestone definitions
  • Risks and open questions

From the requirements document, extract:

  • Functional requirements (numbered list)
  • Non-functional requirements
  • Constraints
  • Success criteria

Cross-reference: for each workpackage, identify which functional requirements it satisfies. This traceability drives the acceptance criteria you write.

If a workpackage cannot be traced to any functional requirement, flag it in your notes as a "traceability gap". Do not silently omit it.


Phase 2: Codebase Scan (Targeted)

For each workpackage, perform a targeted scan of the project codebase to understand what already exists. This prevents you from writing deliverables for things that are already done.

Use these tools:

  • Glob: find files matching patterns implied by the WP description Example: WP is "implement knowledge-load.sh" → Glob **/knowledge-load.sh
  • Grep: search for function names, exports, or CLI commands the WP is expected to produce
  • Read: read existing implementations only when they directly affect what a new WP must deliver

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.
