Verification Lifecycle
This skill defines the complete verification lifecycle that agents must follow for every change: confirm quality gates, classify, check tooling, fail fast, plan, execute, codify (turn each passing verification into a regression test), spec conformance (verify shipped work matches the spec), and loop.
Verification Lifecycle
Agents must follow this mandatory sequence for every change:
- Confirm Quality Gates
- Classify
- Check Tooling
- Fail Fast (if blocked)
- Plan
- Execute
- Codify (turn each passing verification into a regression test)
- Spec Conformance
- Loop
1. Confirm Quality Gates
Confirm that quality gates (tests, typecheck, lint, format) pass. These are prerequisites, NOT verification. Do not count them as verification — they are enforced automatically by hooks and CI. If quality gates fail, fix them before proceeding.
2. Classify
Determine which empirical verification types apply based on the change. Check each type in the Verification Types table in .claude/rules/verification.md against the change scope. Every applicable type requires running the actual system and observing results — not just running tests.
3. Check Tooling
For each required verification type, discover what tools are available in the project. Use the Tool Discovery Process below.
Report what is available for each required type. If a required type has no available tool, proceed to step 4.
If a required verification type needs sign-in or other credentials, exhaust credential sources before declaring the verification blocked. Check credential sources in this order:
- Project e2e / Playwright config and fixtures, including files such as
e2e/constants.ts, e2e/fixtures/api-login.ts, seeded test users, and OTP-bypass patterns such as 555555.
.lisa.config.local.json and environment variables.- Documented ticket credentials, including a
Sign-in Required or equivalent section in the issue, ticket, PRD, or linked implementation notes.
Report which sources were checked. Do not say credentials are unavailable until all three source classes have been checked or proven absent.
4. Fail Fast
If a required verification type has no available tool and no reasonable alternative, escalate immediately using the Escalation Protocol. Do not begin implementation without a verification plan for every required type.
If credentials are genuinely unavailable after the credential lookup order above is exhausted, treat the work item as blocked rather than done. Post a clear tracker comment stating exactly what runtime behavior could not be verified and which credential sources were checked, transition the item to the configured blocked state, and apply the configured needs-human / human-review label, creating that label if the tracker supports label creation and it is missing.
5. Plan
For each verification type, state:
- The specific tool or command that will be used (NOT test/typecheck/lint — those are quality gates, not verification)
- The expected outcome that constitutes a pass
- Any prerequisites (running server, seeded database, auth token)
A verification plan that only lists bun run test, bun run typecheck, or bun run lint is NOT a verification plan. Those are quality gates handled in step 1.
For a user-visible Fix, or a Build change that affects user-visible behavior, the verification plan must include the highest practical observation level for the reported surface. If the project has a browser, device, or end-to-end harness for the affected platform, plan a deterministic regression spec against that surface and the empirical command that observes the same surface. Unit-level or API-only verification does not satisfy a UI-surface defect when browser/device automation is available.
The lead cannot waive, defer, or demote this regression spec as optional, "if cheap", or equivalent. The only acceptable exits are a recorded absence of an end-to-end harness for the platform, or a genuine technical blocker that is captured before merge as a linked build-ready follow-up ticket referenced from the PR and source work item.
6. Execute
After implementation, run the verification plan. Execute each verification type in order.
Evidence output must explicitly label each verification result as either verified empirically or artifact-only / verification deferred. Artifact-only evidence can support a blocked escalation packet, but it cannot mark a required runtime verification complete.
For a required user-visible regression spec, evidence must prove execution, not only existence. Record a CI log line, reporter output, or equivalent artifact that names the new spec and shows it ran and passed in the PR. A green CI run without named execution proof is not enough; explicitly check for test.skip, suite-level environment gates, shard filters, and "0 tests" passes.
If auto-merge is enabled while the regression spec is still in flight, disable auto-merge or apply an equivalent merge gate until the spec commit is pushed and its CI execution proof is available. Do not let the PR merge before the required regression deliverable is satisfied or formally blocked through the linked follow-up path.
7. Codify
After each empirical verification produces PASS evidence, invoke the codify-verification skill to encode the verification as an automated regression test. The manual proof becomes a repeatable check that catches future regressions.
The codify-verification skill maps the verification type to the appropriate framework (Playwright for browser/UI, integration test for API/DB/auth, benchmark for performance, etc.), generates a deterministic test that asserts the same observable outcome the verification just confirmed, runs it in isolation to confirm PASS, and commits it in the same PR as the change.
Codification is mandatory for every empirical verification type with one exception set: PR, Documentation, Deploy, and Investigate-Only spikes — those have inherently non-behavioral proof. For every other type, skipping codification is not allowed; if codification is genuinely impossible (e.g., the test framework does not exist and cannot be installed in scope), escalate via the Escalation Protocol rather than silently skipping.
For UI-surface defects with an available browser/device/e2e harness, codification must happen in that harness or the nearest surface-equivalent automated harness. Lower-level tests may be added for diagnosis or edge cases, but they do not replace the reported-surface regression spec.
A change is not "verified" in the lifecycle sense until each empirical verification has both passed AND been codified.
8. Spec Conformance
After empirical verification produces evidence, run spec conformance as a separate, mandatory step. Invoke the spec-conformance skill (or delegate to the spec-conformance-specialist agent) with the spec source — plan file, JIRA/Linear/GitHub key, or PRD.
Spec conformance answers a question empirical verification does NOT: does the shipped work match what was asked, section-by-section? It consumes the empirical evidence from step 6 and builds a coverage matrix over every requirement (acceptance criteria, Out of Scope, technical commitments, Validation Journey assertions, deliverables).
Required outputs:
- Coverage matrix with one row per requirement
- Scope creep findings (Out-of-Scope violations, surfaced separately from misses)
- Untraceable change findings (diff not traceable to any requirement)
- Verdict:
CONFORMS, PARTIAL, or DIVERGES
PARTIAL or DIVERGES blocks completion. Fix the gaps (implement the miss, remove the creep, capture the missing evidence) and re-run both empirical verification AND spec conformance. Never skip this step — it catches failures that empirical verification by itself does not, such as a feature that works but wasn't asked for, or a spec item that was quietly dropped.
9. Loop
If any verification, codification, or spec-conformance check fails, fix the issue and re-verify. Do not declare done until all required types pass, all empirical verifications are codified, AND the spec-conformance verdict is CONFORMS. If a verification, codification, or conformance check is stuck after 3 attempts, escalate.
Tool Discovery Process
Agents must discover available tools at runtime rather than assuming what exists. Check these locations in order:
- Project manifest — Read the project manifest file for available scripts (build, test, lint, deploy, start, etc.) and their variants
- Script directories — Search for shell scripts, automation files, and task runners in common locations (
scripts/, bin/, project root)
- Configuration files — Look for test framework configs, linter configs, formatter configs, deployment configs, and infrastructure-as-code definitions
- MCP tools — Check available MCP server tools for browser automation, observability, issue tracking, and other capabilities
- CLI tools — Check for available command-line tools relevant to the verification type (database clients, HTTP clients, cloud CLIs, container runtimes)
- Environment files — Read environment configuration for service URLs, connection strings, and feature flags that indicate available services
- Documentation — Check project README, CLAUDE.md, and rules files for documented verification procedures
If a tool is expected but not found, report the gap rather than assuming it doesn't exist — it may need to be installed or configured.
Verification Surfaces
Agents may only self-verify when the required verification surfaces are available.
Verification surfaces include:
Action Surfaces
- Build and test execution
- Deployment and rollback
- Infrastructure apply and drift detection
- Feature flag toggling
- Data seeding and state reset
- Load generation and fault injection
Observation Surfaces
- Application logs (local and remote)
- Metrics (latency, errors, saturation, scaling)
- Traces and correlation IDs
- Database queries and schema inspection
- Browser and device automation
- Queue depth and consumer execution visibility
- CDN headers and edge behavior
- Artifact capture (video, screenshots, traces, diffs)
If a required surface is unavailable, agents must follow the Escalation Protocol.
Tooling Surfaces
Many verification steps require tools that may not be available by default.
Tooling surfaces include:
- Required CLIs (cloud, DB, deployment, observability)
- Required MCP servers and their capabilities
- Required internal APIs (feature flags, auth, metrics, logs, CI)
- Required credentials and scopes for those tools
If required tooling is missing, misconfigured, blocked, undocumented, or inaccessible, agents must treat this as a verification blocker and escalate before proceeding.
Proof Artifacts Requirements
Every completed task must include proof artifacts stored in the PR description or linked output location.
Proof artifacts must be specific and re-checkable. A proof artifact should contain enough detail that another agent or human can reproduce the verification independently.
Acceptable proof includes:
- Automated session recordings and screenshots for UI work
- Request/response captures for API work
- Before/after query outputs for data work
- Metrics snapshots for performance and scaling work
- Log excerpts with correlation IDs for behavior validation
- Benchmark results with methodology for performance work
Statements like "works" or "should work" are not acceptable.
Self-Correction Loop
Verification is not a one-shot activity. Agents operate within a three-layer self-correction architecture that catches errors at increasing scope. Each layer is enforced automatically — agents do not need to invoke them manually.
Layer 1 — Inline Correction
Trigger: Every file write or edit.
Hooks run formatting, structural analysis, and linting on the single file just written. Errors are reported immediately so the agent can fix them before writing more files. This prevents error accumulation across multiple files.
Agent responsibility: When a hook blocks, fix the reported errors in the same file before proceeding to other files. Do not accumulate errors.
Layer 2 — Commit-Time Enforcement
Trigger: Every commit.
Checks run on staged files: linting, formatting, secret detection, commit message validation, and branch protection. This layer catches errors that span multiple files or involve staged-but-not-yet-checked changes.
Commit-time checks cannot be bypassed. Agents must discover what specific checks are enforced by reading the project's hook configuration.
Layer 3 — Push-Time Enforcement
Trigger: Every push.
The full project quality gate runs: test suites with coverage thresholds, type checking, security audits, unused export detection, and integration tests. This is the last automated checkpoint before code reaches the remote.
Handling failures: When a push fails, read the error output to determine which check failed. Fix the root cause rather than working around it. Agents must discover what specific checks are enforced by reading the project's hook configuration.
Regeneration Over Patching
When the root cause of errors is architectural (wrong abstraction, incorrect data flow, fundamentally broken approach), delete and regenerate rather than incrementally patching. Incremental patches on a broken foundation accumulate tech debt faster than the self-correction loop can catch it.
Signs that regeneration is needed:
- The same file has been edited 3+ times in the same loop without converging
- Fixing one error introduces another in the same file
- The fix requires disabling a lint rule or adding a type assertion
Standard Workflow
Agents must follow this sequence unless explicitly instructed otherwise:
- Restate goal in one sentence.
- Identify the end user of the change.
- Confirm quality gates pass (tests, typecheck, lint, format) — these are prerequisites, NOT verification.
- Classify empirical verification types that apply to the change (UI, API, Database, etc.).
- Discover available tools for each verification type.
- Confirm required surfaces are available, escalate if not.
- Plan verification: state tool, command, and expected outcome for each type. Do NOT list test/typecheck/lint here — those are quality gates from step 3.
- Implement the change.
- Execute verification plan — run the actual system and observe results.
- Collect proof artifacts.
- Codify — for each passing empirical verification, invoke
codify-verification to encode it as a regression test (Playwright for UI, integration test for API/DB/auth, benchmark for performance, etc.) and commit the test in the same PR.
- Run spec conformance — build coverage matrix against the spec source (plan/ticket/issue), flag scope creep and untraceable changes, produce verdict.
- Summarize what changed, what was verified, what was codified, conformance verdict, and remaining risk.
- Label the result with a verification level.
Task Completion Rules
- Run the proof command before marking any task complete
- Compare output to expected result
- If verification fails: Fix and re-run, don't mark complete
- If verification blocked (missing tools, services, etc.): Mark as blocked, not complete
- Must not be dependent on CI/CD if necessary, you may use local deploy methods found in the project manifest, but the verification methods must be listed in the pull request and therefore cannot be dependent on CI/CD completing
- Evidence manifest satisfied (leaf work units): For a leaf work unit (Bug / Task / Sub-task / Improvement) whose ticket carries a Validation Journey, do not mark the ticket complete or transition it out of in-progress until every
[EVIDENCE: name] marker declared on the ticket has a corresponding captured, non-empty artifact attached to the ticket. A missing or empty artifact for any declared marker blocks completion exactly like a failed verification — fix and re-capture, or escalate; never close with an unsatisfied manifest. Epics / Stories / Spikes are exempt (coordination containers, not work units).
- No artifact-only completion for required runtime verification: If empirical verification is required and cannot run because credentials are missing, do not mark the item done on artifact-only evidence. Exhaust the credential lookup order first; if still blocked, post the blocker comment, move the item to the configured blocked state, and apply the configured
needs-human / human-review label.
Escalation Protocol
Agents must escalate when verification is blocked, ambiguous, or requires tools that are missing or inaccessible.
Common blockers:
- VPN required
- MFA, OTP, SMS codes
- Hardware token requirement
- Missing CLI, MCP server, or internal API required for verification
- Missing documentation on how to access required tooling
- Production-only access gates
- Compliance restrictions
- Missing runtime credentials after checking project e2e / Playwright config and fixtures,
.lisa.config.local.json / environment, and documented ticket credentials
When blocked, agents must do the following:
- Identify the exact boundary preventing verification.
- Identify which verification surfaces and tooling surfaces are missing.
- Attempt safe fallback verification (local, staging, mocks) and label it clearly.
- Declare verification level as PARTIALLY VERIFIED or UNVERIFIED.
- Produce a Human Action Packet.
- Pause until explicit human confirmation or tooling is provided.
For tracker-backed work items, also post the packet to the tracker, transition to the configured blocked state, and apply the configured needs-human / human-review label. If the label is missing and the tracker supports label creation, create it before applying it.
Agents must never proceed past an unverified boundary without surfacing it to the human overseer.
Human Action Packet Format
Agents must provide:
- What is blocked and why
- What tool or access is missing
- Exactly what the human must do
- How to confirm completion
- What the agent will do immediately after
- What artifacts the agent will produce after access is restored
Example:
- Blocked: Cannot reach DB, VPN required.
- Missing: Database client access to
db.host and internal logs viewer.
- Human steps: Connect VPN "CorpVPN", confirm access by running connectivity check to
db.host, provide credentials or endpoint.
- Confirmation: Reply "VPN ACTIVE" and "ACCESS READY".
- Next: Agent runs migration verification script and captures schema diff and query outputs.
Agents must pause until explicit human confirmation.
Agents must never bypass security controls to proceed.
Environments and Safety Rules
Allowed Environments
- Local development
- Preview environments
- Staging
- Production read-only, only if explicitly approved and configured for safe access
Prohibited Actions Without Human Approval
- Writing to production data stores
- Disabling MFA or security policies
- Modifying IAM roles or firewall rules beyond scoped change requests
- Running destructive migrations
- Triggering external billing or payment flows
If an operation is irreversible or risky, escalate first.
Artifact Storage and PR Requirements
Every PR must include:
- Goal summary
- Verification level
- Proof artifacts links or embedded outputs
- How to reproduce verification locally
- Known limitations and follow-up items
Preferred artifact locations:
- PR description
- Repo-local scripts under
scripts/verification/
- CI artifacts linked from the build
Definition of Done
A task is done only when:
- End user is identified
- All applicable verification types are classified and executed
- Verification lifecycle is completed (classify, check tooling, plan, execute, codify, spec conformance, loop)
- Required verification surfaces and tooling surfaces are used or explicitly unavailable
- Proof artifacts are captured
- Every passing empirical verification is codified as a regression test (or has an explicit, documented skip reason from the allowed set)
- For a leaf work unit, every
[EVIDENCE: name] marker declared in its Validation Journey has a captured, non-empty artifact attached to the ticket (the evidence manifest is fully satisfied)
- Spec conformance verdict is
CONFORMS (not PARTIAL, not DIVERGES)
- Verification level is declared
- Risks and gaps are documented
If any of these are missing, the work is not complete.
