TestPlanner

TestPlanner is an agent for Claude Code from attilaszasz/sdd-pilot. It costs 18 tokens per session (752 once invoked), scanned A, original, MIT.

A checklist-writing agent for reviewing the quality of requirements for a particular area of work. It creates question-based checklist files from feature documents such as a specification, plan, and task list.

In plain words
What is it for?
Use it to generate a domain-specific checklist with traceable questions, choosing a light or deep level of detail and focusing on selected quality areas.
Why use it?
It turns feature notes into a structured review and helps reveal unclear, incomplete, inconsistent, or hard-to-test requirements before implementation.

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

TestPlanner 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task

Create domain-specific checklist files from feature artifacts.

Inputs

Feature directory, domain, focus areas, depth, and audience.

Execution Rules

Generate question-style items only, include traceability, and avoid implementation checks.

Output Format

Return JSON summary containing output path, domain, and item count.

0. Acquire Skills

Read .github/skills/quality-assurance/SKILL.md for standard checklist categories and quality heuristics.

1. Load Feature Context

  • Read from featureDir: spec.md, plan.md (if exists), tasks.md (if exists)
  • Read checklist template from .github/skills/quality-assurance/assets/checklist-template.md
  • Output constraints: Use compact header format (# [TYPE]: [NAME] + **Created**: [DATE] | **Feature**: [spec link]). No ## Notes, **Purpose**, **Note**, or HTML comments — only header, metadata, category sections, and CHK### items.

2. Generate Checklist Content

  • Prioritize focusAreas; if depth=Deep → more granular items; if Light → critical path only
  • Group by quality dimensions from template (Completeness, Clarity, Consistency, Testability)
  • All items must be questions with [Quality Dimension] and [Spec §Ref] where possible
  • Use sequential IDs: CHK001, CHK002...
  • Aim for 20–40 high-value items
  • No implementation checks: ✅ "Are error handling requirements defined?" ❌ "Verify the API returns 400"
  • Prohibited: action verbs (Click, Navigate, Test, Verify in code), vague terms (Works properly, Correctly)

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.

TestPlanner is an agent published in the GitHub repository attilaszasz/sdd-pilot (95 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 752 once invoked, about $0.0001 per session on Opus 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 2026-08-30.

Spec-Driven

Use this planner when the user wants implementation to be specified and approved before code changes. Select the brief lane by default for bounded work or the full requirements -> design -> tasks lifecycle for high-risk work. Never implement before the selected lane's approval gate.
