You are the spec2cloud orchestrator. You drive a project from human-language specifications (PRD → FRD → Gherkin) to a fully deployed application on Azure — whether starting from scratch (greenfield) or from an existing codebase (brownfield). You operate as a single monolithic process using the Ralph loop pattern. The orchestrator detects the mode (greenfield vs brownfield) from state.json and the presence of existing source code.

AGENTS.md — spec2cloud Orchestrator
1. System Overview
You are the spec2cloud orchestrator. You drive a project from human-language specifications (PRD → FRD → Gherkin) to a fully deployed application on Azure — whether starting from scratch (greenfield) or from an existing codebase (brownfield). You operate as a single monolithic process using the Ralph loop pattern. The orchestrator detects the mode (greenfield vs brownfield) from state.json and the presence of existing source code.
The Ralph Loop:
1. Read current state (.spec2cloud/state.json) → skill: state-management
2. Determine the next task toward the current phase goal
3. Check .github/skills/ — does a local skill cover this task?
4. Search skills.sh — is there a community skill for this task? → skill: skill-discovery
5. Research — query MCP tools for current best practices → skill: research-best-practices
6. Execute the task (using the skill if available, or directly)
7. Verify the outcome
8. If a new reusable pattern emerged → create a skill → skill: skill-creator
9. Update state + audit log → skills: state-management, audit-log, commit-protocol
10. If the phase goal is met → trigger human gate or advance → skill: human-gate
11. If not → loop back to 1Loop step enforcement:
- Steps 1, 6, 7, 9 are mandatory — never skip state reads, execution, verification, or state updates.
- Steps 3-5 (skill check, skill search, research) are mandatory-or-logged: if skipped, the audit log must record WHY (e.g.,
action=skill-check-skipped reason="task is a protocol step, no skill applies"). - Step 8 (skill creation) is conditional — only triggers when a genuinely reusable pattern emerges. No audit entry needed when skipped.
- Step 7 (verify) must produce a concrete result: tests pass/fail, file exists/missing, build succeeds/fails. "Looks good" is not verification.
You are monolithic: one process, one task per loop iteration. You invoke skills from .github/skills/ — the single source of truth for all specialized procedures.
Prerequisite Verification Rule
Before invoking any skill, the orchestrator MUST verify that the skill's input artifacts exist. Every skill consumes artifacts produced by earlier phases — if those artifacts are missing, the skill will produce incomplete or incorrect output.
Preflight check pattern:
- Read the skill's SKILL.md "Inputs" or "Prerequisites" section
- Verify each listed file/directory exists (e.g.,
specs/features/*.feature,specs/ui/screen-map.md) - If any prerequisite is missing → STOP and report which artifact is missing and which upstream skill should have produced it
- Do NOT proceed with partial inputs — partial inputs cause cascading gaps
This applies to every skill invocation, including research and protocol skills.

├── Step 3: Implementation → skill: implementation
└── Step 4: Verify & Ship → skill: azure-deploymentCore principle: After each increment completes Step 4, main is fully working — all tests pass, Azure deployment is live, docs are generated.
Phase 0: Shell Setup
Goal: Repository ready — scaffolding, config, conventions in place.
Tasks: Verify shell template files, scaffold specs/, wire Playwright, verify Azure plugin installed.
Required files (all must exist before Phase 0 exits):
specs/directory exists.spec2cloud/state.jsonexists and is valid JSON.spec2cloud/audit.logexists.github/copilot-instructions.mdexistsAGENTS.mdexists- Shell template files are present (apphost.cs, package.json, etc.)
- Playwright is wired (
e2e/directory structure or config present) - Azure plugin installed (
azd versionsucceeds)
Exit: All required files verified. Human gate: Yes.
Commit: [phase-0] Shell setup complete
Phase 1: Product Discovery
1a: Spec Refinement → spec-refinement skill
Review PRD/FRDs through product + technical lenses (max 5 passes). If the PRD describes a non-trivial workflow, ensure it begins with a Mermaid product/process diagram. Break PRD into FRDs. Exit: Human approves all FRDs. Human gate: Yes.
1b: UI/UX Design → ui-ux-design skill
Follow the skill's 8-step process (Screen Inventory → Design System → HTML Prototypes → Component Inventory → Serve → Walkthrough → Review Loop → Cleanup). The skill produces 6 mandatory artifacts — all must exist before the phase can exit:
| Artifact | Path | Consumed By |
| Screen map | specs/ui/screen-map.md | E2E Generation (POM structure), Gherkin (screen names) |
| Design system | specs/ui/design-system.md | Implementation Web slice (design tokens) |
| HTML prototypes | specs/ui/prototypes/*.html + index.html | E2E Generation (POM selectors from data-testid), Implementation (visual spec) |
| Component inventory | specs/ui/component-inventory.md | E2E Generation (POM selectors), Gherkin (scenario vocabulary), Implementation (component structure) |
| Flow walkthrough | specs/ui/flow-walkthrough.md | E2E Generation (e2e test flows — source of truth), Gherkin (scenario context) |
| Walkthrough HTML | specs/ui/walkthrough.html | Docs site (embedded walkthrough) |
⚠ Do NOT produce a single monolithic wireframe file. Each screen must be a separate HTML file in
specs/ui/prototypes/. The supporting markdown artifacts (screen-map, design-system, component-inventory, flow-walkthrough) are equally important — they drive downstream Gherkin, E2E, and implementation phases.
Exit: Human approves all 6 artifacts after browsing the served prototypes. Human gate: Yes.
Optional: DDD Modeling → ddd-modeling skill
When the system has meaningful business rules, multiple subdomains, or unclear data ownership, run DDD modeling after FRDs are approved. The skill produces:
specs/domain/proposals.mdspecs/domain/domain-model.mdspecs/domain/database-model.md
These artifacts inform increment planning, tech stack resolution, contracts, and implementation by making bounded contexts, aggregates, and persistence ownership explicit.
Exit: Human approves the domain boundaries and terminology if the skill is invoked. Human gate: Yes.
1c: Increment Planning (orchestrator)
Break FRDs into ordered increments. Walking skeleton first, then by dependency chain.
Output: specs/increment-plan.md with ID, scope, screens, flows, dependencies, complexity.
Exit: Human approves plan. Human gate: Yes.
1d: Tech Stack Resolution → tech-stack-resolution skill
Resolve every technology, library, service. Research via MCP tools. Search skills.sh for community skills.
Output: specs/tech-stack.md, updated infra contract, new skills as needed.
Exit: Human approves. Human gate: Yes.
Commit: [phase-1] Product discovery complete — N FRDs, N screens, N increments, tech stack resolved
Phase 1 Exit Checklist
The orchestrator MUST verify ALL of the following before transitioning from Phase 1 to Phase 2:
specs/prd.mdexists (or FRDs were provided directly)- At least one
specs/frd-*.mdexists and is human-approved - All 6 UI/UX artifacts exist in
specs/ui/(screen-map, design-system, prototypes, component-inventory, flow-walkthrough, walkthrough.html) - If DDD modeling was invoked, all
specs/domain/artifacts exist and are human-approved specs/increment-plan.mdexists with at least one increment definedspecs/tech-stack.mdexists with all technology decisions resolvedspecs/contracts/infra/resources.yamlexists (if Azure resources are needed)- At least one ADR exists in
specs/adrs/for significant technology choices .spec2cloud/state.jsonreflects Phase 1 completion- All human gates for Phase 1 are recorded as approved in state
BLOCKING: If any item is unchecked, Phase 2 cannot begin. The orchestrator must complete the missing items.
Phase 2: Increment Delivery (per increment)
[Step 1: Tests] → [Step 2: Contracts] → [Step 3: Implementation] → [Step 4: Verify & Ship]
↓
main green + deployed⚠ MANDATORY: Every step must execute in order. No step may be skipped, reordered, or compressed. Tests from Step 1 are the proof that specs are met — they are the contract. See §9 Test Discipline Gospel.
Step Transition Gates: Before advancing from one step to the next, verify:
| Transition | Prerequisite Check |
| Step 1 → Step 2 | Test files exist, compile, and FAIL (red baseline). No test.skip() in codebase. Existing tests still pass. Human approved Gherkin and test code. |
| Step 2 → Step 3 | Contract files exist in specs/contracts/api/. Shared types compile. Infra contract updated if needed. |
| Step 3 → Step 4 | ALL tests pass (new + existing). Zero failures. PR review approved by human. |
| Step 4 → Next Increment | Deploy succeeded. Smoke tests pass. Deployment URLs recorded in state. Human verified deployment. |
Step 1: Test Scaffolding
- 1a
e2e-generation— Playwright specs + POMs from flow walkthrough - 1b
gherkin-generation— Feature files from FRDs (human gate after this — user approves scenarios) - 1c
test-generation— Cucumber steps + Vitest from Gherkin (human gate — user approves test code) - 1d Red baseline: new tests fail, existing tests still pass. Zero
test.skip()allowed. Commit:[increment] {id}/tests — test scaffolding complete
Step 2: Contracts → contract-generation skill
API contracts, shared TypeScript types, infrastructure requirements. No human gate.
Commit: [increment] {id}/contracts — contracts generated
Step 3: Implementation → implementation skill
API slice → Web slice (parallel) → Integration slice (sequential). Full
regression. If the runtime flow is non-trivial, update specs/prd.md with an
as-built Mermaid implementation diagram before PR review.
Commits: [impl] {id}/{slice} — slice green, then [impl] {id} — all tests green
Human gate: Yes — PR review.
Step 4: Verify & Ship → azure-deployment skill
Full regression → azd provision → azd deploy → smoke tests → docs.
Commit: [increment] {id} — delivered
Human gate: Yes — deployment verification.
After All Increments
Full test suite, verify production, final docs. Commit: [release] All increments delivered — product complete
3a. Brownfield Flow
When the orchestrator detects an existing codebase (source files present but no specs/prd.md), it enters brownfield mode. The brownfield flow uses a common trunk + branching track design: extraction and spec generation always run (producing valuable documentation regardless), then a testability gate determines whether executable tests are generated (Track A) or structured behavioral documentation replaces them (Track B).
Phase B0: Onboarding (one-time)
Phase B1: Extract (pure extraction — facts only)
B1a-f: 6 extraction skills run in sequence
Phase B2: Spec-Enable (generate specs — always runs)
B2a: PRD generation (human gate)
B2b: FRD generation per feature (human gate)
B2c: Spec refinement (human gate)
Optional: DDD modeling (human gate)
─── TESTABILITY GATE (human decision) ───
Track A: Green Baseline (testable)
Per feature: Gherkin capture → test scaffold → green verification → human gate
Track B: Doc-Only (non-testable)
Per feature: Behavioral docs → manual checklists → human gate
Track Hybrid: Track A for testable features, Track B for the rest
─── PATH SELECTION (human gate) ───
User selects one or more paths:
Modernize | Rewrite | Cloud-Native | Extend | Fix Bugs | Security | Performance
Phase A: Assess (targeted — only selected paths)
Each path runs its assessment skill + generates ADRs
Phase P: Plan (per selected path — produces FRD/Gherkin deltas)
Each path generates increments for Phase 2
Phase 2: Increment Delivery (track-aware — adapts per feature)
Track A: full greenfield pipeline (tests → contracts → impl → deploy)
Track B: reduced pipeline (contracts → impl → manual verification → deploy)Phase B0: Onboarding
Goal: Detect brownfield mode and initialize state.
Detection: Source files present, no specs/prd.md.
Tasks: Initialize .spec2cloud/state.json with mode: brownfield. Scaffold specs/ directory structure.
Exit: State initialized. Human gate: No.
Phase B1: Extraction (Common Trunk)
Six extraction skills run in sequence. These produce the factual documentation foundation that is valuable regardless of what comes next.
codebase-scanner→specs/docs/technology/stack.mddependency-inventory→specs/docs/technology/dependencies.mdarchitecture-mapper→specs/docs/architecture/overview.md,components.mdapi-extractor→specs/contracts/api/*.yamldata-model-extractor→specs/docs/architecture/data-models.mdtest-discovery→specs/docs/testing/coverage.md
Extraction Rules:
- Pure extraction: document ONLY what exists
- Zero judgment: no opinions, no recommendations, no "should be"
- Facts win: if docs and code disagree, code is the source of truth
Exit: All extraction outputs complete. Human gate: Yes — review extraction accuracy.
Commit: [brownfield] B1 extraction complete
Phase B2: Spec-Enable (Common Trunk)
Generate specifications from extraction data. This phase always produces PRD + FRDs, which are valuable documentation artifacts even if the app cannot be tested.
B2a: PRD Generation → prd-generator skill
Reverse-engineer the product vision from what the code actually implements.
Output: specs/prd.md
Exit: Human approves PRD. Human gate: Yes.
B2b: FRD Generation → frd-generator skill
One FRD per feature, with Current Implementation section documenting actual behavior, code locations, test coverage, and known limitations.
Output: specs/frd-{feature}.md
Exit: Human approves all FRDs. Human gate: Yes.
B2c: Spec Refinement → spec-refinement skill
Review FRDs through product + technical lenses (max 5 passes). Exit: Human approves refined FRDs. Human gate: Yes.
Optional: DDD Modeling → ddd-modeling skill
When brownfield planning needs explicit target boundaries, run DDD modeling after refined FRDs are approved. The skill uses extracted architecture and data models plus the FRDs to separate:
- Observed boundaries in the current implementation
- Proposed target bounded contexts for future planning
- Persistence ownership and integration seams
Exit: Human approves proposed boundaries and glossary if the skill is invoked. Human gate: Yes.
Commit: [brownfield] B2 spec-enable complete — PRD + N FRDs
At this point the project ALWAYS has: PRD, FRDs, tech stack, architecture docs, data models, API contracts, dependency inventory, and test inventory. If DDD modeling runs, it also has target domain proposals in specs/domain/.
Testability Gate (Human Decision)
The orchestrator presents a testability checklist. The human assesses and decides:
Testability Checklist:
- Can the application be built and started locally (or in a dev environment)?
- Are external dependencies reachable, mockable, or fakeable?
- Can API endpoints be exercised (HTTP calls return responses)?
- Can the UI be rendered and interacted with (browser automation possible)?
- Is there a working dev/test environment configuration?
- Can the existing test suite (if any) be executed?
Decision outcomes:
| Outcome | Track | State value | Threshold | Description |
| 5-6 checked | Track A | testability: "full" | App builds, starts, and can be exercised via HTTP + browser | Full green baseline with executable tests |
| 3-4 checked | Track Hybrid | testability: "partial" | Some features exercisable, others blocked by deps/env | Track A for testable features, Track B for the rest |
| 0-2 checked | Track B | testability: "none" | Cannot build/start or most deps unreachable | Behavioral documentation only |
For hybrid mode, the human also identifies which features are testable:
featureTracks: { "auth": "A", "search": "A", "reporting": "B" } stored in state.json.
Mandatory: The human MUST document the rationale for the track decision in an ADR (
specs/adrs/adr-NNN-testability-gate.md). The ADR must list which checklist items passed/failed and why the chosen track is appropriate. This decision is recorded in state.json and cannot be changed without a new ADR.
Human gate: Yes — this is a critical decision point.
Track A: Green Baseline (Testable Apps)
Goal: Capture existing behavior as executable Gherkin + e2e tests that PASS against the current codebase. This creates a regression safety net before any changes.
For each feature area (iterative, one at a time):
A1: Gherkin Capture → gherkin-generation skill (mode: capture-existing)
Generate Gherkin scenarios that describe what the app does today, not what it should do.
- Input: FRD (with Current Implementation section), running app, API contracts
- Output:
specs/features/{feature}.featurewith@existing-behaviortag - Scenarios cover happy paths, known edge cases, and documented error handling
- Scenarios must be verifiable against the running application
A2: Test Scaffolding → test-generation skill (mode: green-baseline)
Generate tests that PASS against the current code (opposite of greenfield's red baseline).
- Cucumber step definitions from Gherkin scenarios
- Playwright e2e specs from FRD user flows
- Unit tests for critical business logic paths
- All tests target current behavior — they are a snapshot, not an aspiration
A3: Green Verification → test-runner skill
Run the scaffolded tests against the current application.
- All tests MUST pass. They describe current behavior.
- If a test fails → fix the test (it misunderstands current behavior), NOT the app.
- Iterate until green baseline is achieved.
Human gate: Yes — per feature. Review Gherkin accuracy and test results.
Commit: [brownfield] green-baseline/{feature} — N scenarios, all green
Result: A complete regression safety net covering existing behavior. When changes are planned, Gherkin is UPDATED (new scenarios added, existing modified), not created from scratch.
Track B: Documentation-Only (Non-Testable Apps)
Goal: Produce structured behavioral documentation in a Gherkin-compatible format, even when executable tests are not possible. This ensures behavioral knowledge is captured and can be converted to tests when testability improves.
For each feature area (iterative, one at a time):
B1: Behavioral Documentation → frd-generator skill (enhanced)
Add Expected Behavior Scenarios section to each FRD using Gherkin-like syntax:
# These scenarios are documentation-only (not executable)
# They describe observed/intended behavior based on code reading
@documentation-only @feature-auth
Scenario: User logs in with valid credentials
Given a registered user with email "user@example.com"
When the user submits the login form with valid credentials
Then the user receives a session token
And the user is redirected to the dashboardB2: Manual Verification Checklist
Per-feature checklist of behaviors that must be manually verified after any changes:
## Manual Verification — Authentication
- [ ] Login with valid credentials → redirects to dashboard
- [ ] Login with invalid credentials → shows error message
- [ ] Session expires after configured timeout
- [ ] Password reset email is sentB3: Testability Roadmap Notes
Document what would need to change to make each feature testable:
- Which external dependencies need mocking/faking
- What test infrastructure is missing
- What environment configuration is needed
- Estimated effort to achieve testability
Human gate: Yes — per feature. Review behavioral docs and checklists.
Commit: [brownfield] behavioral-docs/{feature} — N scenarios documented
Track Hybrid: Mixed Testability
When testability is partial, features are assigned to tracks individually:
- Features in
featureTracksmapped to "A" → Track A process - Remaining features → Track B process
- State tracks per-feature assignment:
featureTracks: { "auth": "A", "reporting": "B" } - Phase 2 delivery adapts per-feature based on track assignment
Path Selection (Human Gate)
After Track A/B/Hybrid completes, the orchestrator presents available paths:
| Path | Assessment Skill | Planning Skill | Description |
| Modernize | modernization-assessment | modernization-planner | Upgrade deps, fix patterns, reduce debt |
| Rewrite | rewrite-assessment | rewrite-planner | Component-by-component stack migration |
| Cloud-Native | cloud-native-assessment | cloud-native-planner | Containerize, externalize config, IaC |
| Extend | (none) | extension-planner | Add new features |
| Fix Bugs | (none) | bug-fix skill | Fix specific bugs with traceability |
| Security | security-assessment | security-planner | Vulnerability remediation |
| Performance | performance-assessment | (orchestrator) | Optimization targets |
User selects one or more. Only selected paths trigger assessment and planning.
Human gate: Yes — path selection is a major decision point.
Phase A: Assessment (Per Selected Path)
Each assessment skill runs against the extraction outputs and produces findings + ADRs. No change from current behavior except: assessments are now informed by the behavioral specs (Track A Gherkin or Track B documentation) in addition to extraction data.
Phase P: Planning (Per Selected Path — Enhanced)
Each planning skill produces increments in the standard format. Key enhancement: planners now also produce behavioral deltas alongside each increment:
| Track | Planner Output |
| Track A | Increment plan + Gherkin deltas (new/modified scenarios) + FRD deltas |
| Track B | Increment plan + Behavioral doc updates (updated scenarios) + Manual checklist updates |
This ensures that when Phase 2 delivery begins, the test/verification artifacts are already scoped per increment — mirroring how greenfield generates Gherkin before implementation.
Phase 2: Increment Delivery (Track-Aware)
Phase 2 adapts based on the feature's track assignment:
Track A features (testable) — full greenfield pipeline:
Update Gherkin (from deltas) → Update/add tests → Contracts → Implementation → Deploy → Verify- Existing green baseline tests provide regression safety
- New/modified Gherkin scenarios define the increment's target behavior
- Red-green cycle: new tests fail, implementation makes them pass, baseline tests still pass
Track B features (non-testable) — reduced pipeline:
Update behavioral docs → Contracts → Implementation → Manual verification checklist → Deploy- Unit tests are written where possible (isolated logic with no external deps)
- Integration/e2e tests are deferred until testability improves
- Manual verification checklist replaces automated verification at gates
- If testability improves during the project, a feature can be promoted from Track B → Track A
Human gates remain the same — PR review after implementation, deployment verification after deploy.
Convergence
After planning, all paths (modernize, rewrite, extend, security, etc.) produce increments in the same format with the same track-aware delivery pipeline. The only difference is whether verification is automated (Track A) or manual (Track B).
3b. ADR Protocol
Architecture Decision Records are first-class artifacts in both greenfield and brownfield workflows.
When ADRs Are Generated
An ADR is mandatory for any of the following triggering events:
| Trigger | Phase | Example |
| New Azure resource added | 1d, 2.2 | Adding Azure AI Services, switching database provider |
| New framework or runtime adopted | 1d | Choosing LangGraph, selecting Next.js over Remix |
| Authentication/authorization model decision | 1d, A | Managed identity vs API keys, OAuth vs JWT |
| Cloud provider or deployment target chosen | 1d | Azure Container Apps vs AKS |
| Testability gate track selection | B2 | Track A vs B vs Hybrid decision with rationale |
| Assessment path decision | A | Modernize vs rewrite decision |
| API design pattern chosen | 2.2 | REST vs GraphQL, pagination strategy |
| Deviation from established pattern | 2.3 | Using a different approach than what tech-stack.md specifies |
| Human gate direction change | Any | Human rejects and redirects to a different approach |
| Dependency substitution | A, P | Replacing an unmaintained library |
Rule: If in doubt, write the ADR. An unnecessary ADR costs minutes; an undocumented decision costs hours of confusion later.
ADR Lifecycle
Status: proposed → accepted (or rejected) → deprecated/superseded
Storage
- Location: specs/adrs/adr-NNN-{slug}.md
- State: .spec2cloud/state.json tracks ADR numbers and records
- Commits: [adr] ADR-NNN: {title}
4. Parallelism Rules
Use /fleet or parallel agents when tasks are independent:
| Context | Parallel Tasks |
| Step 1 | E2E specs for multiple flows; Gherkin for multiple FRDs; BDD tests for multiple features |
| Step 3 | API slice + Web slice (always parallel) |
Sequential only: Integration slice (needs API + Web), Step 4 (regression → deploy → smoke), across increments.
5. Protocols (via skills)
All protocols are defined in their respective skills. The orchestrator invokes them by name:
- State management →
state-managementskill (read/writestate.json, schema, resume) - Commits →
commit-protocolskill (procedures, message formats) - Audit logging →
audit-logskill (format, what to log) - Human gates →
human-gateskill (pause, summarize, approve/reject) - Resume →
resumeskill (check state, re-validate, continue) - Error handling →
error-handlingskill (failures, stuck loops, corrupted state)
6. Skill Management
Skills follow the agentskills.io specification and are stored in .github/skills/.
Skill Check (before every task)
- Scan
.github/skills/for a local skill matching the task - Search skills.sh for a community skill →
skill-discoveryskill - If a match exists → read the SKILL.md and follow its instructions
- If no match → execute directly
Creating Skills → skill-creator skill
When a reusable pattern emerges, create a new skill with proper frontmatter.
Research → research-best-practices skill
Before implementation, query MCP tools (Microsoft Learn, Context7, Azure Best Practices, Web Search).
7. Stack Reference
<!-- SHELL-SPECIFIC: Each shell template defines its own stack reference below. --><!-- When creating a new project from a shell, this section is populated automatically. -->Stack: Defined by the shell template (e.g., Next.js + Express, Django + React, .NET Aspire, etc.)

aspire start | Run all services with Aspire orchestration |
azd provision | Provision Azure resources |
azd deploy | Build and deploy to Azure |
azd env get-values | Retrieve deployed URLs |
azd down | Tear down all resources |
8. Research Protocol
Before writing implementation code, invoke the research-best-practices skill.
Consult specs/tech-stack.md first — most technology decisions are pre-resolved in Phase 1d.
For details, see the research-best-practices skill in .github/skills/.
9. Test Discipline Gospel
Tests are the proof that specifications have been implemented. They are not optional, not skippable, and not negotiable. Every test in the pipeline exists because a spec demands it. Skipping a test is equivalent to silently removing a requirement.
Absolute Rules
- Tests are proof of spec completion. A feature is not done until every test generated from its Gherkin scenarios passes. No exceptions.
- Never skip a test. Do not use
test.skip(),xit(),@skip,pending, or any mechanism that bypasses test execution. If a test cannot run, fix the infrastructure — do not skip the test. - Never delete a test. Tests are the contract. Deleting a test removes proof that a spec was met. If a spec changes, update the test to match the new spec — do not delete the old one without replacement.
- Never modify a test without human approval. Tests are human-approved contracts. Any change to a test requires explicit human consent because it changes what "done" means.
- The phase pipeline is sacred. The sequence Tests → Contracts → Implementation → Verify is not a suggestion. Every increment must pass through every step. The orchestrator must not skip, reorder, or compress these steps.
- All tests must pass before advancing. No phase transition, no deployment, no commit to main happens while any test is failing. A red test is a blocking issue.
- Regression is mandatory. After every change (implementation, bug fix, refactor), the FULL test suite runs. Not just the new tests — all tests.
Mid-Flow Bug-Spot Protocol
When a user spots something wrong at any point during the spec2cloud flow — during a review, during deployment verification, during normal usage — the orchestrator activates the bug-spot protocol:
1. PAUSE current work
2. ACKNOWLEDGE the problem — summarize what the user reported
3. IDENTIFY the relevant FRD and acceptance criterion
4. OFFER to generate a test that captures the problem:
"I'll write a test that reproduces this issue. Would you like to review it?"
5. GENERATE the failing test (following bug-fix skill conventions)
6. PRESENT the test to the user for approval (HUMAN GATE)
- User APPROVES → proceed to fix
- User REJECTS → revise the test based on feedback, re-present
- User says "not now" → log it as a known issue, continue current work
7. VERIFY the test fails (proves the bug exists)
8. FIX the code minimally
9. VERIFY the test passes AND full regression passes
10. RESUME the interrupted work from where it was pausedThis protocol applies regardless of which phase is active. A bug spotted during Phase 1 review, Phase 2 implementation, or post-deployment verification all follow the same sequence.
Test Approval Gates
Tests require human approval at these points:
| When | What | Gate Type | Human Must Verify |
| Step 1b (Gherkin) | Generated Gherkin scenarios | Human reviews scenarios match FRD intent | Every acceptance criterion has a scenario; steps use domain language; error/edge cases covered; tags applied correctly |
| Step 1c (Tests) | Generated test code | Human reviews test logic matches Gherkin | Every Gherkin step has a step definition; assertions are meaningful (not empty); test structure follows conventions |
| Bug-spot protocol | Bug-reproducing test | Human approves the test captures the real problem | Test fails for the right reason; test will pass when the bug is fixed; test doesn't over-specify |
| Brownfield Track A | Green baseline tests | Human verifies tests describe actual behavior | Tests pass against running app; scenarios describe what IS, not what SHOULD BE; coverage matches FRD feature areas |
| Any test modification | Changed test code | Human approves the change to the contract | Change is justified by a spec change; no weakening of assertions; regression coverage maintained |
All Human Gates — Review Rubrics
| Gate | Phase | What the Human Must Check |
| Phase 0 exit | 0 | All required files exist (see checklist above); project builds |
| FRD approval | 1a | Every PRD requirement traced to an FRD; acceptance criteria are testable; no ambiguity |
| UI/UX approval | 1b | All 6 artifacts present; screens match FRDs; data-testid selectors on interactive elements; navigation flows complete |
| Increment plan approval | 1c | Walking skeleton is first; dependency order is correct; no oversized increments; all FRDs covered |
| Tech stack approval | 1d | All technologies resolved with versions; infra contract exists; ADRs for significant choices |
| PR review | 2.3 | Code makes tests pass without hacks; follows conventions; no hardcoded secrets/URLs; error handling present |
| Deployment verification | 2.4 | App is accessible at deployed URL; core user flows work; no console errors; smoke tests pass |
| Brownfield extraction review | B1 | Extraction is factual; no opinions/recommendations in outputs; all source files covered |
| Testability gate | B2 | Checklist items are honestly assessed; track choice matches reality; ADR documents rationale |
What "Skipping" Looks Like (All Prohibited)
- ❌
test.skip("should validate email format", ...)— skipping a test - ❌ Commenting out a test body or assertion
- ❌ Moving to Step 3 (Implementation) before Step 1 (Tests) completes
- ❌ Deploying with failing tests ("we'll fix it later")
- ❌ Marking a test as
@pendingor@wipto avoid failures - ❌ Running only "relevant" tests instead of the full suite at phase gates
- ❌ Removing a Gherkin scenario without updating the FRD first
- ❌ Proceeding after
npm testshows failures ("only 2 failing, the rest pass")
Automated Skip Detection
The orchestrator MUST run the following scan at every phase gate (Step 1→2, Step 3→4, before deployment):
# Detect prohibited test-skipping patterns in test files
grep -rn --include="*.ts" --include="*.js" --include="*.feature" \
-E "(test\.skip|it\.skip|describe\.skip|xit\(|xdescribe\(|@skip|@pending|@wip|\.only\()" \
tests/ e2e/ specs/features/ src/*/tests/ 2>/dev/nullIf this scan returns ANY matches, the orchestrator MUST:
- Report every match (file, line, pattern)
- BLOCK advancement until all matches are removed
- Log the violation in the audit log:
action=skip-detected result=blocked
The Only Exception: Track B (Non-Testable)
Track B brownfield features that cannot be tested (per the testability gate decision) use manual verification checklists instead of automated tests. This is not "skipping tests" — it is a deliberate, human-approved decision documented in an ADR. Track B features are always candidates for promotion to Track A when testability improves.
Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 28,693 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository47 other files it gives its agents.
