analyze

Analyze a collection of documents to build a knowledge map, identify themes, find gaps, duplicates, conflicts, and staleness, then produce an organized analysis with improvement recommendations. Designed for document ecosystems (cross-repo docs, research collections, mixed-format doc repos) where the challenge is understanding the landscape, not auditing against code.

audit

Audit existing project documentation for quality, completeness, consistency, and code alignment. Scans docs against the actual codebase to find stale references, missing coverage, internal contradictions, and quality issues. Generates a structured findings report with severity levels and actionable fix recommendations. Works on any project with a docs/ directory.

decompose

Lightweight project decomposition skill. Analyzes project scope through a brief interview and determines whether the project should be treated as a single feature or split into multiple sub-features. For multi-split projects, generates a project manifest listing sub-features, dependencies, and execution order.

idea

Use when exploring a new idea before writing formal specifications. Guides users through iterative discovery, research, and critical analysis to crystallize vague ideas into validated requirement drafts. Includes anti-pseudo-requirement checks, competitive research, demand evidence gathering, and "What if we don't build this?" analysis. Supports pause/resume across sessions, stores ideas in the project's ideas/ directory, and graduates validated ideas into the spec-forge auto chain (idea → decompose → tech-design + feature specs).

prd-generation

Generates professional Product Requirements Documents (PRDs) following industry-standard methodologies. This skill activates when the user asks to write PRD, create a product requirements document, draft product requirements, do product planning, do feature planning, write a product spec, or create a product document. It synthesizes best practices from the Google PRD framework, the Amazon Working Backwards methodology, and the Stripe Product Spec approach to produce comprehensive, actionable PRDs tailored to the user's project.

Code & Development Listed

review

Review spec-forge generated documents (tech-design + feature specs) for quality, completeness, and internal consistency. Finds issues like incomplete sections, contradictions, missing traceability, and vague specs, then optionally auto-fixes them. Supports iterative review-fix cycles with a maximum of 2 iterations.

srs-generation

Generates professional Software Requirements Specification (SRS) documents based on IEEE 830, ISO/IEC/IEEE 29148, and Amazon technical specification standards. This skill activates when the user needs a requirements document, requirements specification, SRS, functional requirements, non-functional requirements, software requirements, requirements analysis, or requirements engineering. It formalizes product needs into structured, testable, and traceable requirements with unique IDs, acceptance criteria, use cases, a CRUD matrix, and a full traceability matrix linking back to the upstream PRD.

Web & Frontend Listed

tech-design-generation

Generates professional Technical Design Documents following industry-standard engineering practices. This skill activates when the user asks to write a technical design, create an architecture design, draft a design doc, write a technical proposal, do system design, create a technical design document, write an RFC, create a design document, or produce an architecture document. It synthesizes best practices from the Google Design Doc format, the RFC template structure, and Uber/Meta engineering design standards to produce comprehensive, implementable technical designs tailored to the user's project and codebase.

Testing & QA Listed

test-cases-generation

Generates structured test case sets with multi-dimensional coverage from project code analysis or specification documents. This skill activates when the user asks to write test cases, generate tests, supplement tests, create test coverage, or improve test completeness. It auto-scans the project to extract testable units (APIs, functions, components, CLI commands, tool definitions), identifies coverage gaps, designs test cases across multiple dimensions (coverage depth, input types, interaction patterns), and produces a structured test case document with coverage matrix. Includes test strategy and methodology by default. Use --formal flag to add management sections (environment, roles, schedule, defect management).

Testing & QA Listed

test-plan-generation

Generates professional Test Plan and Test Cases documents following IEEE 829 test documentation standards, ISTQB testing methodologies, and Google Testing Blog best practices. This skill activates when the user asks to write a test plan, create test cases, draft a test plan document, create a test cases document, define a test strategy, write a QA document, produce a testing document, draft a test specification, or build a quality assurance plan. It produces comprehensive, structured test documentation that ensures thorough coverage, traceability to requirements, and a clear path from test design through execution and defect management.

spec-forge

Professional specification system for Codex. Use when the user asks to create, improve, review, audit, analyze, or propagate product/software documentation, including ideas, PRDs, SRS documents, technical designs, architecture/RFC docs, feature specs, test cases, documentation audits, document landscape analysis, and full idea-to-spec chains. Supports complex multi-skill orchestration: idea -> decompose -> tech-design + feature specs -> review, with optional PRD, SRS, test-cases, audit, analyze, and propagate workflows.

propagate

Walk an upstream documentation change downstream — when a PRD, SRS, tech-design, or feature spec is edited, find every dependent document, identify which sections are now stale, and interactively update them to keep the entire doc chain consistent. Use after editing any spec-forge document, or run periodically with --since to catch accumulated drift.
