Testing

Testing

Select the smallest real proof that exercises the changed behavior, then widen only as the repo contract and risk surface require.

When To Use

• Choose validation for code, docs, config, workflow, skill, or eval changes.
• Fix failing tests, classify validation ownership, or design coverage.
• Prove completion before handoff, PR, merge, release, or closeout claims.

Inputs

• Target repo, changed files, nearest instructions, claim under test, repo command contracts, wrapper working directory, environment or credential materialization, prior failures, and known blockers.

Outputs

• Exact commands with pass, fail, or blocked outcomes.
• Failure ownership plus the evidence artifact: log, trace, schema output, eval fixture, package receipt, or workflow-closeout receipt.
• Coverage gaps and next minimal diagnostic.
• When delivery is in scope, the validated report path, delivery receipt path, and exact command that checked each artifact.

Workflow

1. Read the repo instructions and command contracts.
2. Inspect the changed behavior, existing tests or fixtures, and the canonical wrapper that owns them. Identify what is already proved, what rejection or boundary behavior is missing, and whether the wrapper changes into a package root or rewrites paths.
3. Name the exact invariant and proof lane: structural, deterministic behavior, trace analysis, calibrated judge, baseline comparison, regression retention, production guardrail, or delivery receipt.
4. Run the narrowest command that exercises production code, a real CLI/script, validator, schema, artifact path, or installed/package path.
5. If it fails, classify ownership and fix only the in-scope cause. Rerun the same proof before widening. Use the exact same command when it was valid; when the failure came from wrapper-relative paths, working-directory semantics, tool shims, environment materialization, or unsupported flags, preserve the failed command and rerun the corrected canonical command.
6. For validators, schemas, parsers, policy gates, and artifact contracts, require at least one accepted case and one rejected case for each meaningful invariant. Include boundary or false-positive protection when widening detection.
7. Widen through the canonical wrapper, affected suite, schema or artifact lane, and repository-required diff or generated-state checks. Run hosted, review, external, Tessl, runtime, or delivery lanes only when they are in scope.
8. Report only the lanes actually proven. When durable delivery is required, validate the report and delivery receipt after code and test proof.

Evidence shape: unit/workflow; lane; given/should/actual/expected; reproduce command; ownership; status.

Ownership values should distinguish current patch, pre-existing repository defect, unrelated dirty-worktree or generated-state interference, invalid or unsupported command shape, wrapper working-directory mismatch, environment or toolchain failure, trust or credential failure, certificate or network failure, hosted policy or approval boundary, external or runtime dependency, and unknown after bounded diagnostics.

Default widening ladder:

1. Focused regression for the exact invariant.
2. Direct CLI, validator, fixture, or artifact probe of the changed behavior.
3. Canonical package or repo wrapper proving the focused test is wired into the maintained validation route.
4. Wider affected suite, schema spine, typecheck, or scenario/eval preview.
5. Diff, formatting, generated-state, or changed-files checks required by the repository contract.
6. Hosted checks, review-thread state, external review, Tessl, runtime, or delivery receipts only when those lanes are in scope.

Skip a rung when it does not apply, but record the reason. Do not treat a later rung as a substitute for missing earlier behavior proof.

Command Templates

• Skill package: ./bin/ask skills package verify Skills/agent-ops/testing --json --robot
• Strict audit: ./bin/ask skills audit Skills/agent-ops/testing --level strict --json --robot
• External review: ./bin/ask skills external-review Skills/agent-ops/testing --json --robot
• Focused repo proof: run the discovered command, then report Command: <exact command> -> pass|fail|blocked (<reason>).

Examples

• For a change to Skills/agent-ops/testing/SKILL.md, run the strict audit, inspect its JSON status and findings, fix a current-patch header-order failure, and rerun the same audit before package verification.
• For a validator change, retain one accepted fixture and one rejected fixture, run their focused test, then run the canonical wrapper that owns that test. Report behavior proof separately from wrapper wiring and hosted checks.

Failure Mode

Gotchas

• A broad green suite does not prove a touched path unless the command exercises it.
• A process exit code is not enough when the JSON receipt says status: error.
• A validator that accepts known-good fixtures but has no known-bad fixture may prove loading without proving enforcement.
• A top-level success status is not enough when the claim depends on nested counts, findings, validation rows, digests, selected profiles, or receipt fields. Name the semantic fields that establish or contradict the claim.
• When summary fields disagree with detailed artifacts, report the contradiction and prefer the field designated authoritative by the repository contract.

Anti-Patterns

• Reporting a command as green when only a summary or stale artifact was inspected.
• Letting a judge decide objective properties that a parser, schema, or fixture can check.
• Claiming one evidence lane passed because a neighboring lane passed.

Validation

• Prefer repo-native wrappers: ./bin/ask, bash Infrastructure/scripts/validation-and-linting/verify-work.sh, bash Infrastructure/scripts/validation-and-linting/validate-codestyle.sh, package scripts, just, or documented validators.
• Testing evidence must use: Command: <exact command> -> pass|fail|blocked (<reason>).
• Fail fast: stop at the first failed required gate; do not proceed to wider proof until that gate is fixed or classified blocked.
• Blocked steps must name the blocker, the nearest meaningful validation that did run, and what would unblock the exact proof.
• Treat repeated failures, conflicting instructions, dirty worktrees, credentials, network, Tessl, external-review, and runtime checks as separate blocker lanes.
• Before running a discovered wrapper, determine whether it changes directories, rewrites paths, requires a trusted tool configuration, or expects credentials through an approved wrapper. Do not infer a source regression from a path, trust, shim, certificate, or environment-materialization failure.
• When command shape changes, report both attempts and explain why they exercise the same proof lane rather than silently replacing the failed invocation.
• Redact secrets, tokens, credential values, and sensitive log content from commands, receipts, traces, fixtures, and reported evidence.
• Do not run destructive commands unless explicitly requested and allowed.
• Schema-bound outputs include schema_version.

References

• Start with this active contract.
• Load only the reference needed for the current repo and change surface: harness assurance, skill package validation, eval artifact proof, repo route matrix, or persona lenses.
• For imported capsules, use knowledge capsule routing, knowledge capsule index, manifest, and knowledge demand; treat references/evals.yaml and references/evals notes as evidence, not runners.

Execution Boundaries

Run only commands that the repository supports and the user has authorized, starting with the smallest relevant proof. Do not invoke destructive, hosted, or live-evaluation paths merely to improve coverage, and do not widen a blocked lane without classifying the blocker.

Cross-Lane Gotcha

One passing command does not validate adjacent lanes. Preserve exact command shape, distinguish reruns from new evidence, and do not silently replace a blocked production path with a narrower local check.
