Skill Claude CodeCodex
An archiving tool for completed software changes. It creates a summary, synchronizes requirements with feature specifications, and checks that related project knowledge has been updated.

Backfill Spec - Reverse-extract a behavioral Feature Spec draft from existing brownfield code (source = code, not a design tool) for features/capabilities with no spec coverage. Records behavior, never intent; stages a draft for human verify-and-promote and never writes the trust zone. Triggers: backfill spec, spec…
Skill Claude CodeCodex
A design-specification assistant for creating or extracting interface and interaction details. It works with Pencil, Figma, Penpot, or HTML designs.
Skill Claude CodeCodex
A guided thinking partner for clarifying requirements, investigating problems, and comparing possible solutions.
Skill Claude CodeCodex
A fast planning workflow that creates a user story, implementation plan, and task list in one pass. TDD-style RED → GREEN → REFACTOR means writing a failing test, making it pass, and then improving the code.
Skill Claude CodeCodex
An implementation workflow that reads an ordered task list and carries out the tasks one by one. Each finished task is immediately marked in tasks.md, the file holding the work list.
Skill Claude CodeCodex
A project-knowledge generator that reads a raw project scan and turns its structure into small, recipe-based documentation files.
Skill Claude CodeCodex
A documentation update workflow that reads a change specification, finds the affected software modules, and updates only the related project knowledge. A module is a focused part of a codebase, such as a package or service.

Feedback Promotion Pipeline - Collect session corrections, repeated verify FAILs and recurring review criticals into a version-controlled lessons ledger; score them with an explicit, reproducible rule (frequency + impact modules); and promote - only with explicit human approval - across three tiers (accumulating…
Skill Claude CodeCodex
A guided workflow for turning a requested feature or behavior change into a documented user story and acceptance criteria.
Skill Claude CodeCodex
A planning tool that turns a user story—a plain-language description of a desired feature—into a technical plan and a change specification. It uses the Prospec command-line program to create plan.md and delta-spec.md.
Skill Claude CodeCodex
Promote Backfill - Formalize a reviewed backfill-draft.md into the backfill change scaffold (proposal.md + delta-spec.md + metadata.yaml with scale: backfill, status: implemented) so brownfield behavior can graduate through verify → archive. A light scale like quick — no hollow plan.md/tasks.md; the single, repeatable…
Skill Claude CodeCodex
A one-time project onboarding workflow for setting up localized triggers, refreshing agent configuration, and preparing project knowledge generation.
Skill Claude CodeCodex
Adversarial Code Review → Fix Loop - Between implement and verify, an independent fresh-context reviewer audits the whole change diff; verifier-confirmed criticals are auto-fixed, majors are proposed, and a spec-aware lens checks delta-spec/dependency-direction. Triggers: review, code review, adversarial review, find…
Skill Claude CodeCodex
A task-planning workflow that turns an implementation plan and change specification into an actionable checklist.
Skill Claude CodeCodex
Prospec Version Upgrade Finisher - after prospec upgrade records the version, syncs agents, and reports gaps, work through the report's docs inventory: update init-created files whose format drifted and create missing ones (asking consent per file), then localize triggers for newly-added skills and re-sync. Triggers…
Skill Claude CodeCodex
A review skill that checks an implementation against its tasks, written requirements, project rules, supporting knowledge, tests, and—when relevant—its design.
Skill Claude CodeCodex
A skill for publishing a new prospec GitHub release by updating version strings, creating a tag, and writing release notes.
Skill Claude CodeCodex
A skill for opening GitHub issues in the prospec project's required format, with an English conventional-commit title and a Traditional Chinese description.
Skill Claude CodeCodex
A skill for opening a pull request in the prospec project's required format after a change is completed and archived.
