quoin

Convert ISO spec requirements (StR, FR, NFR) into a TDD-based project plan with dependency analysis, parallel execution tracks, quality gates, and task decomposition. Selects or starts a plan and writes a frontmatter-typed plan bundle under plan/<Plan-id>-<slug>/ (Plan + Task + index + log).

Create or update spec artifacts from a design or change request. Orchestrates authoring each requested requirement type (StR/US/FR/NFR/IT) as a discrete file using quoin catalog templates and Quire validation.

Analyze requirement statements (FR/NFR/StR) for EARS requirement-grammar conformance and author a SpecReview of the findings.

Build and maintain the requirements Test Matrix ensuring 100% coverage.

Review requirements for quality, consistency, and completeness.

Verify a targeted plan is complete and validated — every task done, the Test Matrix backed by real tracking tags in tests, and code fully traced to spec (flagging underspecified code with no owning requirement). Optional semantic review checks that intent↔test↔code actually agree. Emits a quire-validated SpecReview artifact to reviews/YY-MM-DD-<slug>.md.

Convert validated requirements into an implementation plan.

Run a composite specification review.

Audit spec domain objects, cross-references, and entity completeness across single or multi-repo ecosystems.

Review an application-type spec for completeness against UI rendering requirements and golden-path structure.

Build and update requirements test matrices.

Analyze dependencies and separate enablement from feature work.

Define verification methods and evidence artifacts for requirements.

Identify unstated failure modes, identity confusion, purity gaps, and topological edge cases in ISO-style specifications.

Use for loose, exploratory specification drafting before formal authoring, review, matrix, or planning work.

Perform quality gate analysis on ISO-style specifications to ensure completeness, consistency, and atomicity.

Identify technical risks and volatility in requirements before tasking.

Define system boundaries and allocate responsibilities for ISO-style specifications.

Analyze specifications and implementations to identify applicable security standards and generate compliance traceability documentation.
