<!-- CODEX:PROJECT-REFERENCE-LOADING:START -->Codex compatibility note:
- Invoke repository skills with
$skill-namein Codex; this mirrored copy rewrites legacy Claude/skill-namereferences.- Task tracker mandate: BEFORE executing any workflow or skill step, create/update task tracking for all steps and keep it synchronized as progress changes.
- User-question prompts mean to ask the user directly in Codex.
- Ignore Claude-specific mode-switch instructions when they appear.
- Strict execution contract: when a user explicitly invokes a skill, execute that skill protocol as written.
- Subagent authorization: when a skill is user-invoked or AI-detected and its protocol requires subagents, that skill activation authorizes use of the required
spawn_agentsubagent(s) for that task.- Do not skip, reorder, or merge protocol steps unless the user explicitly approves the deviation first.
- For workflow skills, execute each listed child-skill step explicitly and report step-by-step evidence.
- If a required step/tool cannot run in this environment, stop and ask the user before adapting.
Codex Project-Reference Loading (No Hooks)
Codex uses static project-reference loading instead of runtime-injected project docs. When coding, planning, debugging, testing, or reviewing, open project docs explicitly using this routing.
Always read:
docs/project-config.json(project-specific paths, commands, modules, and workflow/test settings)docs/project-reference/docs-index-reference.md(routes to the fulldocs/project-reference/*catalog)docs/project-reference/lessons.md(always-on guardrails and anti-patterns)
Missing/stale context route: If docs/project-config.json, the docs index, lessons.md, CLAUDE.md, AGENTS.md, or any task-required reference doc is missing or stale, auto-run $project-init or the narrow setup route ($project-config, $docs-init, $scan-all, $scan --target=<key>, $claude-md-init) before ordinary project-specific work. If Codex mirrors or AGENTS.md are missing/stale, ask the user to run $sync-codex; do not auto-run it.
Situation-based docs:
- Backend/CQRS/API/domain/entity changes:
backend-patterns-reference.md,domain-entities-reference.md,project-structure-reference.md - Frontend/UI/styling/design-system:
frontend-patterns-reference.md,scss-styling-guide.md,design-system/README.md - Spec authoring,
docs/specs/pathing, or TC format:feature-spec-reference.md,spec-system-reference.md,spec-principles.md - Behavior/public-contract changes or spec-test-code sync:

integration-test-reference.md - E2E test implementation/review:
e2e-test-reference.md - Code review/audit work:
code-review-rules.mdplus domain docs above based on changed files
Do not read all docs blindly. Start from docs-index-reference.md, then open only relevant files for the task.
Quick Summary
Goal: Convert one or more canonical 8-section Feature Specs into a complete, sprint-ready PBI backlog.
Canonical input: docs/specs/{Bucket}/README.{Feature}.md (one tech-free 8-section Feature Spec per capability). There is no separate A-E engineering bundle — code is the technical source of truth.
Primary outputs:
team-artifacts/pbis/{date}-pbi-{slug}.mdfor each generated PBI.team-artifacts/backlog/spec-to-pbi-{date}-backlog.mdwith priority order and dependency graph.plans/reports/spec-to-pbi-{date}-{bucket}.mdwith coverage matrix and unresolved questions.
Universal Rules:
- MUST ATTENTION define success criteria before execution and loop until observable verification passes.
- MUST ATTENTION when creating/reviewing specs or tests, name
Business Intent / Invariant Guardedor the protected business intent/invariant and ensure the test would fail if that intent breaks. - [BLOCKING] Tech-agnostic output: PBI / backlog / report prose stays tech-agnostic per
docs/project-reference/spec-principles.md§3 — no framework/product/language/design-pattern names; source paths and class names appear ONLY in evidence fields (**Evidence**,[Source:]), frontmatter, and Mermaid. - [BLOCKING] Inherit M1-M5 + logical-ID carry: See
.claude/skills/shared/sdd-artifact-contract.md→ "AI-SDD Mandates (M1-M6)" for BLOCKING criteria. Every generated PBI MUST satisfy M1-M5. Carry each requirement's logical ID (FR-/BR-) from the spec's requirement/rule statements into the PBI as the PRIMARY citation spine, keeping the spec's[Source: namespace/service/id]abstract-anchor evidence as the SECONDARY carrier (KEEP it). Generated acceptance criteria stay tech-agnostic and observable — one valid interpretation, named failure modes, no implementation details.
When to Use
- User wants to create all PBIs from an existing Feature Spec (or a bucket of them).
- User wants to split a very large Feature Spec into small sprint-ready PBIs.
- User wants a dependency-aware and priority-ranked backlog from
docs/specs/. - User wants shared/foundation tasks identified before feature PBIs.
When Not to Use
- Raw product vision without any Feature Spec -> use
$workflow-idea-to-spec(then chain back here for the backlog). - One informal idea -> use
$workflow-idea-to-pbi. - Spec creation/update only -> use
$workflow-code-to-spec(from code) or$workflow-idea-to-spec(from an idea). - Implementation after PBIs are ready -> use
$workflow-featureor$workflow-big-feature.
Protocol
1. Activate
Run $start-workflow workflow-spec-to-pbi with the user's prompt as context.
2. Load Spec Context
Locate and read, per target capability:
docs/specs/{Bucket}/INDEX.md— the bucket catalog (which capabilities exist)docs/specs/{Bucket}/README.{Feature}.md— the canonical 8-section Feature Spec. Each PBI is decomposed from its sections:- §1 Overview / §3 User Stories & Acceptance Criteria → PBI scope + acceptance criteria
- §4 Business Rules (
BR-) + §3 (US-/AC-) → logical-ID citation spine (M3) - §5 Domain Model (Mermaid ERD) → entity/aggregate impact for
## Domain Impact - §6 Process Flows → vertical-slice story boundaries
- §7 Permissions & Roles → access-control acceptance criteria
- §8 Test Specifications (
TC-) → expected TC categories per PBI
If the spec path is missing or ambiguous, ask the user for the exact bucket / Feature Spec path before generating PBIs.
3. Freshness Gate
Run $spec-index in audit mode before PBI generation.
- If stale behavior is found, run/update the impacted spec sections before generating PBIs.
- If only structural/doc formatting is stale, record the risk and continue.
- If critical domain/API/business-rule sections are stale, stop and ask whether to update specs first.
4. Coverage Matrix
Create a matrix with one row per independently deliverable item:
| Spec Source | Capability | Feature/Operation | Domain Impact | Shared Dependency | PBI Type | Status |
| ---------------- | -------------- | ----------------- | ------------------------- | ----------------- | --------------------------------------------- | ------- |
| {Feature §sec} | {capability} | {feature} | entity/state/event/API/UI | yes/no | feature/foundation/shared/migration/test-data | planned |
Every source feature/operation must map to exactly one of:
- Generated PBI
- Shared/foundation PBI
- Existing PBI reference
- Explicit out-of-scope decision with reason
5. Large Spec Decomposition
Apply these scale rules before creating PBIs:
| Scope | Required Breakdown | | -------------------------- | --------------------------------------------------------------------- | | 1-3 capabilities | Process inline with one task per capability and feature group | | 4-10 capabilities | Split by capability, then feature/operation group | | 10+ capabilities | Incremental capability-group batches with coverage matrix checkpoints | | Any PBI > 8 story points | Split with SPIDR until each PBI is <= 8 story points | | Cross-cutting prerequisite | Create shared/foundation PBI before dependent feature PBIs |
6. Domain Analysis Gate
Run $domain-analysis when any spec item includes:
- New or changed entities, aggregates, value objects, or ownership boundaries
- State machines or lifecycle transitions
- Cross-service event ownership or synchronization
- Data migration or seed/test-data needs
Record domain findings in each affected PBI under ## Domain Impact.
7. PBI Generation Loop
For each matrix row that needs a new PBI:
- Run
$refineto create the PBI artifact. - Run
$review-artifact --type=pbi. - Run
$storyto create vertical-slice stories. - Run
$review-artifact --type=story. - Run
$pbi-challenge. - Run
$dor-gate. - Run
$pbi-mockuponly when UI is involved.
Each PBI MUST include:
- Logical requirement IDs (
FR-/BR-) carried from the spec as the primary citation spine (M3). - Source spec references with
file:sectionevidence (secondary, re-anchorable carrier — KEEP). - GIVEN/WHEN/THEN acceptance criteria — tech-agnostic and observable (M1/M4).
- Story points and complexity.
- Dependencies table with
must-before,can-parallel,blocked-by, orindependent. - Priority input data for
$prioritize. - Test specification needs, including expected TC categories.
- Domain impact and shared/foundation task references.
8. Cross-PBI Prioritization
After all PBI loops finish, run $prioritize once across the full generated set.
The backlog artifact MUST include:
- Rank and recommended implementation order.
- Dependency graph and first-do/blocked/defer groups.
- Foundation/shared tasks first when other PBIs depend on them.
- RICE or MoSCoW rationale.
- DoR status per PBI.
- Remaining open questions.
8.5 Near-Final Documentation Synchronization
Run $docs-update after $prioritize and before $workflow-end.
Purpose:
- Sync generated PBIs/stories/backlog outputs back into the canonical Feature Specs where applicable.
- Sync Feature Spec §8 Test Specifications with the generated TC needs.
- Verify Feature Specs, derived bucket
INDEX.md, and TDD/spec docs do not drift after PBI generation. - Record skipped sub-phases explicitly when no impacted docs exist.
9. Completion Criteria
Workflow can close only when:
- Every spec source item is represented in the coverage matrix.
- Every generated PBI has dependency and priority fields.
- Shared/foundation PBIs are explicit and ordered before dependents.
- Domain-analysis findings are attached where domain changes are implied.
- The final backlog artifact ranks all PBIs and explains what to do first.
$docs-updatehas run as the near-final sync gate, with Feature Specs (§8) and derived bucket indexes either updated or explicitly marked unchanged.

<!-- /SYNC:critical-thinking-mindset --> <!-- SYNC:ai-mistake-prevention -->Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.
<!-- /SYNC:ai-mistake-prevention --> <!-- SYNC:incremental-persistence -->AI Mistake Prevention — Failure modes to avoid on every task:
Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting. Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing. Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first. Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done. Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect. Assume existing values are intentional — ask WHY before changing. Before changing a constant, limit, flag, wording, or pattern, read nearby context and history. Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk. Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.

- Return to main agent: Summary only (per SYNC:subagent-return-contract) with

Everything beyond the summary lives in the

- MANDATORY Parent workflow rows do not replace child phase tracking; expand phases and link the parent when nested.
- MANDATORY Orchestrators pre-expand child skill phases before invocation; use

Hookless Prompt Protocol Mirror (Auto-Synced)
Source: .claude/.ck.json + .claude/skills/shared/sync-inline-versions.md (:full blocks) + .claude/scripts/lib/hookless-prompt-protocol.cjs
[WORKFLOW-EXECUTION-PROTOCOL] [BLOCKING] Workflow Execution Protocol — MANDATORY IMPORTANT MUST CRITICAL. Do not skip for any reason.
Generic portability boundary: Reusable skills and protocol text stay project-neutral; project-specific conventions are discovered from docs/project-config.json and docs/project-reference/. Apply shared AI-SDD from shared/sdd-artifact-contract.md. Read docs/project-config.json and docs/project-reference/docs-index-reference.md, then open the project reference docs named there. For spec, test-case, behavior-change, public-contract, or docs/specs/ work, route through the local spec docs named by the docs index: feature-spec-reference.md, spec-system-reference.md, spec-principles.md, and workflow-spec-test-code-cycle-reference.md when specs/tests/code must stay synchronized. If either file or a required reference doc is missing or stale, auto-run $project-init (or the narrow lower-level route such as $project-config, $docs-init, $scan-all, or $scan --target=<key>) before ordinary project-specific work. Any supported AI tool may execute when this shared context and local docs are available.
- DETECT: If the prompt starts with an explicit slash skill/workflow command, execute it directly. Otherwise match the prompt against the workflow catalog and skill list.
- ANALYZE: Choose the best option: execute directly, invoke a skill, activate a standard workflow, or compose a custom step combination.
- AUTO-SELECT: Pick the best option yourself. Do not ask the user to choose between direct execution, skill, standard workflow, or custom workflow.
- ACTIVATE: For a selected workflow, call
$start-workflow <workflowId>; for a selected skill, invoke that skill; for a custom workflow, sequence custom steps directly; for direct execution, proceed with the task. - CREATE TASKS: task tracking for ALL workflow/skill/custom steps before execution when the selected path has multiple steps.
- EXECUTE: Advance per the Workflow Step Advancement & Parallel Phases rule in your context instructions — model-driven; a sub-agent completion advances a step identically to an inline call; a parallel-phase group is an all-return barrier (advance only after ALL members return, never serialize it)

- Keep reusable AI-SDD principles in
.claude; put repository-specific paths, commands, owners, products, and formats in project config/reference docs.- Preserve cycle:
spec -> plan -> tasks -> implement -> verify -> update spec/docs.- Trace every requirement or invariant through decision, task, TC/test, source evidence, and docs/spec update.
- Treat code-to-spec extraction as reference-only until accepted by the canonical spec owner.

[LESSON-LEARNED-REMINDER] [BLOCKING] Task Planning & Continuous Improvement — MANDATORY. Do not skip.
Break work into small tasks (task tracking) before starting. Add final task: "Analyze AI mistakes & lessons learned".
Extract lessons — ROOT CAUSE ONLY, not symptom fixes:
- Name the FAILURE MODE (reasoning/assumption failure), not symptom — "assumed API existed without reading source" not "used wrong enum value".
- Generality test: does this failure mode apply to ≥3 contexts/codebases? If not, abstract one level up.
- Write as a universal rule — strip project-specific names/paths/classes. Useful on any codebase.
- Consolidate: multiple mistakes sharing one failure mode → ONE lesson.
- Recurrence gate: "Would this recur in future session WITHOUT this reminder?" — No → skip
$learn. - Auto-fix gate: "Could
$code-review/$code-simplifier/$security-review/$lintcatch this?" — Yes → improve review skill instead. - BOTH gates pass → ask user to run
$learn. [CRITICAL-THINKING-MINDSET] Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination principle: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination. AI Attention principle (Primacy-Recency): Put the 3 most critical rules at both top and bottom of long prompts/protocols so instruction adherence survives long context windows. Goal-driven execution: Define success criteria first, loop until verified, and stop only when observable checks pass. Tests verify intent: Tests must protect business rules/invariants and fail when the protected intent breaks, not only mirror current behavior.
Common AI Mistake Prevention (System Lessons)
- Re-read files after context compaction. Edit requires prior Read in same context; compaction wipes read state. Re-read before editing.
- Grep for old terms after bulk replacements. AI over-trusts find/replace completeness. Grep full repo after bulk edits for missed refs in docs/configs/catalogs.
- Check downstream references before deleting. Deletions cascade doc/code staleness. Map referencing files before removal.
- After memory loss, check existing state before creating new. Compaction wipes prior-work memory. Query current state to resume — never blindly duplicate.
- Verify AI-generated content against actual code. AI hallucinates APIs, class names, method signatures. Grep to confirm existence before documenting/referencing.
- Trace full dependency chain after edits. Changing a definition misses downstream consumers. Trace the full chain.
- When renaming, grep ALL consumer file types. Some file types silently ignore missing refs (no compile error). Search code, templates, configs, generated files.
- Trace ALL code paths when verifying correctness. Code existing ≠ code executing. Trace early exits, error branches, conditional skips — not just happy path.
- Update docs that embed canonical data when source changes. Docs inlining derived data (workflows, schemas, configs) go stale silently. Update all embedding docs alongside source.
- Verify sub-agent results after context recovery. Background agents may finish while parent compacted — grep-verify output, don't trust assumed completion.
- Cross-check full target list against sub-agent assignments. Parallel sub-agents by category miss boundary items. Reconcile union of assignments against target list before proceeding.
- Sub-agents inherit knowledge only from their agent .md definition — use custom agent types, not built-in Explore. Tool adoption = permission + knowledge + enforcement (numbered workflow step).
- Persist sub-agent findings incrementally, not as a final batch. Long sub-agents hit cutoffs before final write — findings lost. Instruct append-per-section to report file.
- When debugging, ask "whose responsibility?" before fixing. Trace caller (wrong data) vs callee (wrong handling). Fix at responsible layer — never patch symptom site.
- Grep ALL removed names after extraction/refactoring. Primary file "done" ≠ secondary files clean. Grep entire scope for every removed symbol before declaring complete.
- Assume existing values are intentional — ask WHY before changing. Pattern-matching as "wrong" skips context. Before changing any constant/limit/flag: read comments, git blame, surrounding code.
- Verify ALL affected outputs, not just the first. One build green ≠ all green. Multi-stack changes (backend/frontend/tests/docs) require verifying EVERY output.
- Evaluate fit before copying a nearby pattern. Closest example ≠ matching preconditions — verify the new context shares the same constraints, base classes, scope, lifetime.
- Holistic-first debugging — resist nearest-attention trap. Don't dive into first plausible cause. List EVERY precondition (config, env vars, paths, DB, endpoints, creds, versions, DI, data). Verify each against evidence (grep/query — not reasoning). Ask "what would falsify this?" — if nothing, it's not a hypothesis. Most expensive failure: going deeper in "obvious" layer while bug sits in layer never questioned.
- Surgical changes — apply the diff test (context-aware). Two modes: (1) Bug fix → every line traces to the bug; no restyling; orphan cleanup only for imports YOUR changes made unused. (2) Review/enhancement → implement improvements AND announce as "Enhancement beyond main request: [what]". Never silently scope-creep. Diff test: "Would this line exist if I wasn't asked to do X?" — if no, delete or announce.
- Surface ambiguity before coding — don't pick silently. Multiple valid interpretations → present each with effort: "[Request] could mean (1) [N h], (2) [N h]. Which matters?" List scope/format/volume/constraints assumptions first. If simpler path exists, say so. Never silently pick.
- [MANDATORY FIRST ACTION] ALWAYS activate a suitable skill or workflow BEFORE responding. Match task against workflow catalog + skill list; invoke via skill invocation or
$start-workflow <workflowId>. NEVER answer or write code before checking. Skip = protocol violation. - Why-Review adversarial mindset — apply when reviewing any plan, decision, or design. Default SKEPTIC not VALIDATOR: steel-man a rejected alternative, invert each stated reason ("what does it sacrifice?"), stress-test top 2-3 assumptions, run pre-mortem ("ships, fails in 3 months — what breaks?"), surface 1-2 alternatives author missed. Section presence ≠ quality; quality = causal reasoning + concrete mitigations + evidence, not "it's better" or "monitor closely".
- Front-load report-write in sub-agent prompts for large reviews. Many-file sub-agents hit budget before final write — findings lost. Design prompts so: (1) report-write is first explicit deliverable, (2) append per-file/section (not batched), (3) scope bounded so reads don't exhaust budget. Truncated mid-sentence with no report file → spawn narrower scope, don't retry same prompt.
- After context compaction, re-verify all prior phase outcomes before continuing. Summaries describe intent, not environment state (git index, filesystem, processes). On resume, FIRST audit: git status, re-read modified files, verify filesystem. Every "completed" claim is an untested hypothesis until evidence confirms.
- OOM/memory: check row count before row size. Triage: (1) Unbounded query — no DB filter for trigger? Push filter to DB; eliminates OOM. (2) Large rows? Projection reduces proportionally. Row reduction > projection in ROI.
- Keep domain concepts out of generic/shared/infrastructure layers. Reusable layer (shared library, framework, infra module) must reference NO consumer-specific domain concept — tenant/customer/product IDs, business entities, feature rules. Leak compiles + runs → passes review silently while coupling the "reusable" layer to one consumer. Keep shared type domain-free; push domain fields/logic down into the consumer via subclass/composition. — why: a layer coupled to one consumer's domain is no longer reusable.
