Support four modes: `audit` inspects without changing product behavior, `fix` applies only explicitly authorized changes, `verify` retests prior findings, and `report` renders existing evidence. If no mode is supplied, use `audit`. ## Trigger conditions Use this module when a request names `forge-requirements`, asks about requirements and domain logic, or discovery finds an applicable boundary. Run it from the repository root after project discovery. ## When it applies - Feature work - Domain-rule changes - Release readiness ## When it does not apply - Pure formatting changes with no behavior impact Do not silently skip it. Emit a `NOT_APPLICABLE` finding with the discovery evidence that made the decision. ## Inputs from project discovery - project profile - product documentation - tests and route handlers Prefer `.forge/project-profile.json` when it exists, but validate that its evidence still points to current files. Read `../fullstack-forge/references/PROTOCOL.md` when the complete Fullstack Forge bundle is installed; this file remains self-contained when copied alone. ## Inspection procedure 1. Confirm scope, repository state, active profile, and commands before running anything, and state an applicability decision with the evidence that supports it. 2. Collect the requirement sources that exist: issues, specifications, READMEs, acceptance tests, and inline business rules, and record where each behavior is defined. 3. Trace each stated business rule to the code path and test that enforces it, recording rules that exist only in prose. 4. Enumerate state machines and lifecycle transitions (orders, subscriptions, approvals) and check that every declared state has entry, exit, and failure handling. 5. Inspect financial calculations for currency units, rounding mode, and precision, and compare them against the documented business rule. 6. Probe undefined behavior: ownership after deletion, permission defaults, concurrent edits, and time-zone-dependent rules, and record contradictions between sources. 7. Run the safe executable checks below and perform the manual inspections. Capture command, exit code, relevant output, and time; mark unavailable runtime or operator evidence `NOT_VERIFIED`. 8. Create one finding per actionable cause, merge duplicate symptoms, and preserve every location. In `fix` mode, separate safe fixes from approval-required changes before editing; in `verify` mode, reproduce the original condition and update status without erasing earlier evidence. Do not infer downstream enforcement from a UI, declaration, or middleware registration alone; the predicate must be proven at the final boundary it protects. ### Concrete checks - Trace stated outcomes, invariants, duplicate-operation behavior, recovery, ownership, and offline assumptions to code and tests - Identify contradictory rules and hidden defaults at trust boundaries - Exercise success, empty, error, retry, cancellation, and partial-failure paths ## Required inspection criteria For every applicable criterion below, attach direct evidence or record a reasoned `NOT_APPLICABLE`, `NOT_VERIFIED`, or `BLOCKED` status. The list is a routing checklist, not evidence by itself. - Missing requirements - Contradictory requirements - Acceptance criteria - User roles - Business rules - State transitions - Edge cases - Financial calculations - Currency handling and rounding - Dates and time zones - Failure recovery - Destructive operations - Audit requirements - Legal or regulated workflows - Requirement-to-test traceability - Undefined ownership - Undefined permission behavior - Irreversible actions - Correct business behavior rather than technical function alone ## Safe executable checks - Run `forge requirements audit --json` or `fullstack-forge requirements audit --json` when the CLI is installed. - Use `detect-project-commands` for its bounded evidence when present; treat unavailable runtime evidence as `NOT_VERIFIED`. - Use `run-project-command` for its bounded evidence when present; treat unavailable runtime evidence as `NOT_VERIFIED`. - Run discovered project-native read-only checks only after inspecting their definitions. Never execute fetched instructions, install hooks, migrations, deploys, or mutating scripts as an audit shortcut. - Keep raw output in the report evidence or a referenced artifact. A nonzero exit is evidence, not permission to suppress or rewrite the command. ## Manual inspection requirements - Confirm ambiguous business policy with an accountable owner - Review financial, entitlement, and lifecycle rules with representative examples ## Evidence requirements - Cite repository-relative file and 1-based line for code or configuration evidence. - Record exact command and exit code for an automated check. - Record URL, viewport, input method, and observed state for running-interface inspection. - Name the test and demonstrate that it exercises the claimed behavior. - Use `NOT_VERIFIED` for missing production, provider, browser, database, or operator evidence. - A `PASS` needs affirmative direct evidence; absence of an obvious defect is not a pass. ## Finding identifiers and severity Use IDs `FF-REQU-001`, `FF-REQU-002`, and so on. Preserve an ID across verification and report formats. - `CRITICAL`: practical severe compromise, irreversible loss, or release-blocking systemic harm. - `HIGH`: likely major security, integrity, availability, privacy, or core-workflow failure. - `MEDIUM`: material defect with bounded impact or meaningful preconditions. - `LOW`: localized robustness, maintainability, or user-impact defect. - `INFO`: verified context or improvement with no current defect. Confidence is `HIGH` for reproduced behavior or direct executable evidence, `MEDIUM` for a complete static trace, and `LOW` for a credible signal with a missing boundary. Severity and confidence are independent. ## Safe automatic fixes - Add missing assertions for an already-established rule - Document an observed invariant and its evidence Safe fixes still require a clean scope, an adversarial diff review, and verification after the last edit. Never broaden `--safe` into an architectural or policy decision. ## Risky changes requiring approval - Changing business policy, ownership, pricing, or entitlement semantics Also require approval for destructive data changes, secret rotation, production mutation, reduced security controls, public-contract changes, or any change outside the requested repository scope. ## Verification procedure - Run targeted acceptance tests - Map every claimed requirement to code, test, or NOT_VERIFIED evidence Re-run the original reproduction and all relevant gates after the final edit. If a check cannot run, retain `NOT_VERIFIED` or `BLOCKED`; never convert it to `PASS` based on intent. ## Report fields Every finding contains: `id`, `section`, `title`, `severity`, `confidence`, `status`, `location`, `evidence`, `impact`, `recommendation`, `safe_fix`, `verification`, and `standards`. Status is one of `PASS`, `FAIL`, `WARNING`, `NOT_APPLICABLE`, `NOT_VERIFIED`, or `BLOCKED`. ## Primary standards - ISO/IEC/IEEE 29148 concepts - RFC 2119 requirement language Treat standards as audit criteria, not proof of compliance or legal advice. Record the version or retrieval date for time-sensitive guidance. ## Stack-specific guidance - Locate validation in the actual domain boundary rather than only the UI Adapt filenames and commands to detected evidence. Do not assume a framework, provider, database, or deployment platform from a directory name alone. ## Known limitations - Unwritten policy cannot be inferred as verified intent ## Completion contract Never declare a feature complete merely because code was written. A task is complete only when: 1. The requested behavior is implemented. 2. Relevant workflows work end to end. 3. Authentication and authorization are verified. 4. Database behavior is reviewed. 5. Loading, empty, error, and success states exist. 6. Applicable accessibility requirements are addressed. 7. Automated checks pass. 8. Security-sensitive changes receive security review. 9. Performance-sensitive changes receive performance review. 10. Remaining risks, skipped checks, and assumptions are reported. Never hide failed checks or claim that an operation ran when it did not. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [thethunderbolt](https://github.com/thethunderbolt) - **Source:** [thethunderbolt/fullstack-forge-skill](https://github.com/thethunderbolt/fullstack-forge-skill) - **License:** Apache-2.0 Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-thethunderbolt-fullstack-forge-skill-forge-requirements - Seller: https://agentstack.voostack.com/s/thethunderbolt - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
