Conciseness

The 7-step workflow is stated three times — the 'Per-Step Agent Map' table, the full step sections, and the 'Instructions' summary — and 'Atomic (DOCTRINE 12.2.8)' is repeated in nearly every section, while the trailing 'Overview' and 'Output' sections restate the frontmatter and Output Format. Nearly all content is operational rather than concept explanation, so it sits above 'noticeably verbose' (2) but below 'efficient with only minor trims' (4).

Actionability

Gives exact dispatch strings ('Searcher — locating bug reproduction in recent changes/tests'), concrete reviewer checklists, verdict enums ('CONFIRMED', 'FALSIFIED ALL', 'PARTIALLY CONFIRMED'), a full worked example transcript, and a copy-paste output-format block — fully executable guidance for an instruction-only skill, with the common cases (failing test, symptom-patch request, intermittent bug) covered by examples.

Workflow Clarity

Seven explicitly numbered steps each gated by a Reviewer, with explicit feedback loops ('Loop back to Step 2 with a broader evidence scope', 'loop Step 5 with the Reviewer's specific objection attached'), loop limits ('After 2 full cycles, surface to user'), and an error-handling table covering repro failure, flakiness, falsified hypotheses, and missing test runner — matching the anchor for clear sequence plus validation, recovery loops, and checklists.

Progressive Disclosure

Core workflow lives in the body with one-level-deep, clearly labeled references to real bundle files ([worker-prompt.md](references/worker-prompt.md), [reviewer-prompt.md](references/reviewer-prompt.md), [memory-system.md](references/memory-system.md), [output-style.md](references/output-style.md)) and an annotated Resources section. Not 5: it also depends on paths outside the bundle ([DOCTRINE.md](../hyperflow/DOCTRINE.md), ../../agents/searcher.md, ../../agents/debugger.md) and repeatedly cites DOCTRINE rule numbers (12.2.8, 14, 18) whose meaning requires following those external links.

Specificity

Names the debugging domain and 1–2 concrete actions — 'Systematic root-cause analysis before any patch' and 'ends with a final-integration review of the fix' — but omits the skill's other capabilities (reproduction, evidence gathering, hypothesis verification, regression testing). Not 2 because the actions named are concrete rather than generic; not 4 because coverage of what the skill does is incomplete.

Completeness

Explicitly answers both: what — 'Systematic root-cause analysis before any patch — never blind-patches symptoms' — and when, with a 'Use when encountering...' clause plus a second 'Trigger with...' sentence listing concrete trigger phrases. The 'when' is maximally explicit with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Excellent natural coverage — 'bugs, test failures, runtime errors, broken builds' plus quoted user phrases 'debug this', 'find the root cause', 'why is this failing', 'this test is broken'. Not 5 because common synonyms like 'crash', 'stack trace', 'exception', and 'flaky' are absent; well above 3's 'some relevant keywords'.

Distinctiveness Conflict Risk

The 'Systematic root-cause analysis... never blind-patches symptoms' positioning carves a clear debugging niche distinct from review/deploy skills. Not 5 because the trigger surface ('bugs, test failures, runtime errors, broken builds') is broad enough to overlap a generic fix-the-test or build skill; clearly above 3's 'could still overlap with similar skills'.
