SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When creating or editing a Codex skill, the standard validation workflow relies on subagent pressure testing, but delegation is often unavailable, policy-gated, or not explicitly authorized. This Skill preserves the RED-GREEN-REFACTOR discipline without violating the active runtime's delegation policy. ## Core Features & Use Cases - Delegation-Aware Validation Decision: Checks whether subagents are explicitly authorized before choosing a validation path, and records why independent pressure testing was unavailable. - Non-Delegated RED-GREEN-REFACTOR: Uses documented real failures or deterministic fixtures for RED, minimal skill edits for GREEN, and cleanup plus re-validation for REFACTOR. - Honest Reporting: Explicitly distinguishes local fixture checks from independent agent pressure testing in the final report. - Use Case: You are editing a skill in a runtime where subagents may only be used on explicit request. This Skill guides you to build deterministic RED fixtures, make the smallest compliant edit, run the skill-creator validator, and report the validation limitation. ## Quick Start Use writing-skills-extras to validate this skill edit without spawning subagents, following the non-delegated RED-GREEN-REFACTOR workflow.

FAQPage Schema
How do I validate a skill when subagents are not available?

Use a non-delegated RED-GREEN-REFACTOR workflow: document a real failure or write deterministic fixtures for RED, make the smallest skill edit for GREEN, then re-run all fixtures and the skill-creator validator. Record why independent pressure testing was unavailable.

What is a RED fixture in skill validation?

A RED fixture is a deterministic test written before editing that records the prompt, active policy, expected behavior, and failure condition. It fails because the required guidance is absent, confirming the failure is the intended one.

Can I skip validation if subagent delegation is not authorized?

No. Lack of subagent authority changes the validation method but does not authorize skipping validation. You must run local fixtures and structural checks, and report that these are not an independent agent pressure test.

When should I offer independent forward-testing for a skill?

Offer optional independent forward-testing only when it would materially improve confidence in the skill change. Do not imply that local fixture checks are equivalent to independent testing.

What are the limitations of non-delegated skill validation?

Local fixture checks are not an independent agent pressure test, so they may miss behavioral issues a separate agent would catch. The final report must explicitly state this validation limitation.
