Use during code authoring + spec-review. Four practices bundled: (1) impact-aware test selection — run tests the changed files transitively reach, not just the ones you wrote; (2) anti-over-mock cue — no mocks outside test files; (3) complexity-delta gate during review — measure lines vs behaviour; (4) dual-reader ambiguity probe at SPEC review — second reviewer asks 'what does this permit/forbid that disagrees'.

Evidence Cluster

Four practices bundle here because they share one root: the artefact has to do the right thing, not just exist.

Use Cases

Invoke this skill when implementing a behaviour change (impact-aware tests + anti-over-mock), when reviewing a diff (complexity-delta gate), when reviewing a SPEC (dual-reader ambiguity probe).

The Four Practices

1. Impact-Aware Test Selection

Before declaring a behaviour change done:

Identify the files you modified.
Identify tests that transitively reach those files (import graph, not just sibling tests).
Run THAT set, not just the tests you wrote.
Cite the test run as a tool-receipt (execution-discipline-cluster cross-ref).
If a predicate or contract gates behavior, execute it against the live filesystem/runtime before sign-off (file://specs/2026-06-22-fleet-sync-self-reconcile/SPEC_EVIDENCE.md SE-1).

For the BES fleet today the helpers are:

bash .claude/hooks/tests/run-tests.sh — fleet hook impact.
bash agents/scripts/<helper>.sh --self-test — per-helper impact.

2. Anti-Over-Mock Cue

Rules:

NEVER add mock, jest.mock, vi.mock, MagicMock, etc. outside test files. Production code that needs a mockable seam should use dependency injection at module boundaries (per standards §U15 boundary validation).
One mock per test, not many. Over-mocked tests test the mock, not the behaviour.
If you find yourself mocking the database in more than half your tests the architecture is test-hostile. Surface it.

3. Complexity-Delta Gate (during review)

When reviewing a diff:

Measure lines added vs behaviour added.
If the code added is roughly an order of magnitude more than the behaviour warrants, flag as complexity-bloat. (Calibration: a ~200-line PR that adds one new public-API function is fine; ~2000 lines for that same one function is suspect — ~10x too much. Advisory cue, not a lint-enforced ratio.)
Check imports added — every new dep is a long-lived liability; new deps without deps_added SPEC declaration are blocked by block-undeclared-deps.sh but advisory deps inside a node_modules churn warrant review.

4. Dual-Reader Ambiguity Probe (at SPEC review)

When cross-family reviewing a SPEC:

Pick one normative claim per major section.
Ask: "What behaviour does this permit / forbid that another reader might disagree on?"
If the answer is "nothing" you've read it tightly; if the answer reveals interpretive surface, surface the ambiguity as a finding.

This is distinct from existing diff-review — the ambiguity probe targets the SPEC TEXT's interpretive surface, not the implementation.

Hard Rules

Do not declare a behaviour change done without running impact-aware tests.
Do not add mocks to non-test files.
Do not let a PR whose size dwarfs its behaviour by ~an order of magnitude land unchallenged (see the complexity-delta cue above).
Do not skip the ambiguity probe on Contract SPECs — Contract is the most-binding artefact type.

repo-orientation

buildepicshit/agentic-installation-methodology

Use at the start of work in any BES repo to build a current, cited map of instructions, repo state, verification gates, active plans, and likely risk before editing.

approved-spec-decomposition

buildepicshit/agentic-installation-methodology

BLOCKING. Use after a SPEC.md is approved and before in-execution to emit one TASK.md per executable slice into specs/<id>/tasks/. Each TASK.md carries primary/cross-validation/verification model lanes and gates the parent SPEC's transition approved -> decomposed -> in-execution. Tasks are the source-of-truth dispatchable units that agents execute directly; no external tracker (Linear) or dispatcher (Symphony) is required.

code-review

buildepicshit/agentic-installation-methodology

Use for reviewing local diffs, branches, or PRs. Prioritises bugs, regressions, missing tests, unsafe assumptions, and broken repo contracts over surface polish. Do not use to author or review SPEC.md / IDEA.md artefacts — use spec-review for that BLOCKING gate.

cross-agent-cli-invocation

buildepicshit/agentic-installation-methodology

Use when you (an agent) intend to invoke another agent's CLI from Bash — claude calling copilot, copilot calling claude, or any equivalent cross-agent pattern. Read at session start whenever you might fire `claude` or `copilot` from a Bash tool call. The skill documents the gotchas, points at the validator helper, and explains where the mechanical block fires.

diagnosis

buildepicshit/agentic-installation-methodology

Use when debugging a failure, flaky behavior, regression, broken command, or unclear root cause. Builds a fast deterministic feedback loop before fixing.

execution-discipline-cluster

buildepicshit/agentic-installation-methodology

Use during every execution-phase task AND whenever answering any question with a knowledge gap. Six practices bundled: (1) tool receipts; (2) in-flight failure disclosure; (3) receiving-code-review; (4) ground before you answer; (5) confidence-band declarations on completion-report claims; (6) escalation rubric — stop and surface or reset rather than grind. Inherits the canonical exit-code mapping from the CLI invocation contract.
