Prd Os

prd-os

Formal, repo-native workflow for PRD creation and PRD execution inside Claude Code. An independent reviewer is the gate at both phases: Codex, or a Claude senior-staff-engineer subagent when Codex is unavailable.

Whichever reviewer ran is recorded in the findings ledger as codex-review, codex-adversarial, claude-review, or claude-adversarial. Stamping one for another puts false provenance in a repo whose thesis is receipts. Enforcement is partial and the boundary matters: the REVIEWER_SOURCES validator in findings_writer.py refuses any value outside that set (so manual and plan cannot fill a review gate), but no checker can tell which of the four actually ran. That last step is a model decision with no gate behind it.

Status

Operational. Plugin version is authoritative in .claude-plugin/plugin.json; the state machines, commands, and gates below are shipped and enforced by the runner scripts. CHANGELOG.md carries the per-version history.

State machines

PRD: idea -> draft -> in-review -> draft (on revise) -> approved -> archived.

Issue: open -> in-progress -> closed. Receipts required between approve and close: verified, reviewed, findings_triaged.

Commands

PRD side (this plugin): /prd-start, /prd-review, /prd-triage, /prd-approve, /prd-split, /prd-archive, /prd-personas, /prd-map.

There is no /prd-revise command. A PRD returns to draft via prd_runner.py advance draft after triage.

Issue side ships in the kipi-dsse plugin, not this one: /issue-start <id>, /issue-approve, /issue-verify, /issue-review, /issue-closeout, /issue-amend. The two plugins share the .prd-os/ state directory and the findings ledger.

Bootstrap: /prd-os-init (runs once per repo to scaffold .prd-os/, write config.json, and add the runtime state dir to .gitignore). It does NOT register hooks -- that claim shipped through 0.17.0 with no code behind it (ASK-402). Hooks come from this plugin's hooks/hooks.json when the plugin is enabled.

Ledger CLI (no slash command; run through kipi judgment <subcommand>): the Judgment Compiler freezes decision-time workflow context for each triage decision into an append-only hash-chained receipt ledger. See scripts/judgment_compiler.py and the operator guide.

Non-negotiables

• PRD drafting must not drift into implementation. Scope enforcement restricts edits to the PRD file during drafting.
• Issue planning stays in open status. The stop-gate does not arm until /issue-approve transitions to in-progress.
• Empty allowed_files means deny-all except the active spec itself (control-plane carve-out). This is a fixed contract; do not propose allow-all behavior.
• Every finding gets a disposition before approve or closeout. The enum is exactly pending, accepted, rejected, deferred (DISPOSITIONS in findings_writer.py); the writer refuses anything else. No finding may be left pending. rejected and deferred require --rationale.
• Concurrent PRD and issue contexts are blocked. /prd-start refuses if an issue is in-progress; /issue-start refuses if a PRD is in-review.
• The reviewer never edits. Claude is the sole editor. Codex runs through /codex:review and /codex:adversarial-review and returns findings for Claude to triage; a Claude reviewer subagent runs read-only under the same contract.
• Runtime state (.claude/state/active-{prd,issue}.json) is never committed. The bootstrap command adds the state directory to .gitignore.
• Out-of-scope findings are never dropped. A deferred disposition auto-creates an open spillover item, and gates run stays red until it is resolved. See Spillover below.

Spillover: out-of-scope findings never vanish

An issue found mid-work that is out of scope must be CAPTURED, not mentioned. The ledger is .prd-os/spillover.jsonl; the standing gate enforces it.

• Capture: prd_runner.py spillover add --source <id> --severity <medium|high|major|blocker> --desc "..." (a deferred triage disposition does this automatically; rejected does not). A new minor/low/nit is refused (exit 2): fix it now or reject it with a reason.
• Gate: prd_runner.py gates run FAILS while any item is open — the same no-bypass re-proof as the registered gates. Forgetting an item = a red gate.
• Resolve: spillover resolve <id> --resolution-ref <closed-issue-id> (refuses unless that issue is actually closed) or --void "<reason>" for a non-item.
• Report: closeout/archive name each item, its resolving issue, the fix, and the system impact. See the .claude/rules/no-orphan-findings.md rule.

Portable core vs repo-local split

Plugin (portable): commands, runner scripts, hooks, templates, review rubric, findings schema, tests.

Repo (local): .prd-os/config.json, .prd-os/prds/, .prd-os/issues/, .prd-os/findings/, .claude/state/.

Ledger files (spillover.jsonl, gates.jsonl, judgments.jsonl) resolve to the shared worktree ledger root, so parallel worktrees write to one ledger rather than diverging copies.

Execution discipline

fable-discipline is this plugin's execution-discipline layer (recon before edit, verify against a copy with a negative self-test, single-writer chokepoints, scar-anchored why-comments). /issue-start loads it for PRD/DSSE work; the fable-discipline-auto-invoke rule loads it for everything else. Its deterministic slice (test isolation) is enforced by the fable-discipline-lint hook in this plugin's hooks.json.

Load-path warning

These commands run from the marketplace clone (~/.claude/plugins/marketplaces/<mp>/), not from a project's plugins/ directory. An edit to a project copy is inert until the clone is refreshed. Confirm which copy is live before relying on a change to command or skill text.

Upgrade policy

Plugin follows semver. MAJOR bumps may change the state machine, remove commands, or change the findings schema; they require operator action. MINOR bumps are additive. PATCH bumps are fixes. Config schema version is tracked separately in .prd-os/config.json and bumps only when the runner cannot load older configs without migration. See CHANGELOG.md.
