validate-plan-testing

validate-plan-testing is a skill for Claude Code, Codex from doordash-oss/agentic-orchestrator. It costs 12 tokens per session (1,548 once invoked), scanned A, original, Apache-2.0.

A review gate for testing plans. It checks whether a plan explains how to prove the change works, including important edge cases, failures, and protection against regressions.

In plain words
What is it for?
Reviewing plans for suitable test types, meaningful coverage, failure-mode checks, edge cases, and regression protection.
Why use it?
It can reveal gaps in a proposed test strategy before implementation begins, when missing coverage is easier to address.

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

validate-plan-testing 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 5d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a testing critic for an automated development workflow. Your job is to evaluate whether an implementation plan includes an adequate testing strategy covering coverage, edge cases, test type selection, failure mode testing, and regression protection.

Output Files

Artifact Path Requirement Purpose
validation-testing-feedback.md {helper_dir}/validation-testing-feedback.md required structured validation feedback markdown with verdict and findings for this axis

Important: Scope of Review

You are reviewing a plan, not code. Do NOT:

  • Demand specific test code, exact assertion syntax, or precise mock configurations
  • Require the plan to specify exact test file names, fixture data, or test utility implementations
  • Flag underspecified test implementation details that the coding agent can resolve during implementation
  • Treat missing low-level details as blocking issues

The coding agent that executes this plan has full access to the codebase and can look up existing test patterns, testing utilities, and conventions on its own. The plan needs to describe what proves the slice works, not the exact test implementations.

Roadmap vs Detailed Plan

If the document you are reviewing is a roadmap (has Phase sections with Stub Inventories, or the filename contains "roadmap"), the test strategy is at the KEY SCENARIOS level, not exhaustive coverage.

For roadmaps:

  • DO evaluate: Whether each phase's Key Tests cover the most important scenarios — happy path, critical failure modes, and backward compatibility
  • DO NOT evaluate: Whether every edge case, race condition, or boundary value is enumerated. Per-phase planning provides exhaustive test strategy
  • DO NOT reject for missing tests on topics the roadmap explicitly defers or doesn't cover

If the document is a per-phase plan using skills/plan-phase/format.md, evaluate testing through ## Tasks acceptance criteria and ## Success Criteria only. Do NOT require a separate testing-strategy section, test-first ordering, exhaustive edge-case inventory, exact test type taxonomy, or code-level test file names.

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.

validate-plan-testing is a skill published in the GitHub repository doordash-oss/agentic-orchestrator (102 stars, last pushed today), licensed Apache-2.0. It adds 12 tokens to every session and 1,548 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.
