Quality

Content

46%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is lean and well-sectioned, but it functions as a stub: all operational substance is delegated to archived references that are absent from the bundle, leaving the executor with abstract directives and no way to follow them. Validation posture (fail-fast, observable criteria) is stated but generic, with no recovery loop.

Suggestions

Ship the referenced bundle files (Infrastructure/references/contract.yaml, evals.yaml, task-profile.json, subagent-routing.md, routing-map.json, assets/icons) at the paths the body links to, or inline the essential policy — currently every link is broken and 'load the archived full guide' has no target.

Make the procedure executable: add a concrete inspection checklist (what counts as hidden coupling, a missing checkpoint, an untreated risk), a template or example of the deepened-plan output, and the action to take after a failed gate besides stopping.

Trim the meta sections (Progressive Disclosure Entry preamble, 'Use', 'Philosophy') and deduplicate the subagent-routing pointers, which appear in both 'Full Context' and 'Subagent Routing'.

DimensionReasoningScore

Conciseness

The body is short, bullet-driven, and assumes Claude's competence without explaining known concepts. Minor trimmable waste remains: the meta "Progressive Disclosure Entry" preamble, the near-empty "Use" section, and the subagent-routing link duplicated across "Full Context" and "Subagent Routing".

4 / 5

Actionability

The procedure is high-level direction ("Inspect current plan for ambiguity", "Deepen task sequencing, validation strategy, and rollback posture") with no method, template, or example of a deepened plan, and the files that would carry the concrete detail (contract.yaml, evals.yaml, task-profile.json, the "archived full guide") do not exist in the bundle — the "load the archived full guide" instruction points nowhere.

2 / 5

Workflow Clarity

A clear 3-step sequence exists and the Validation section includes an explicit fail-fast gate ("stop at first failed gate and do not proceed"), but the checkpoints are generic (no method for verifying "observable completion criteria"), there is no feedback loop beyond stopping, and the core step 2 is a single vague directive.

3 / 5

Progressive Disclosure

The entry-point shape is right — a concise SKILL.md with clearly signaled, one-level-deep references — but scored against the actual bundle, every referenced path is dangling: no references/, scripts/, or assets/ directories exist, so contract.yaml, evals.yaml, task-profile.json, subagent-routing.md, routing-map.json, and the icons are all unreachable and the disclosure structure is non-functional.

Description

67%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A solid description with a clear what/when structure and a distinct niche within its skill family. Its main weakness is trigger-term quality: the activation phrases are methodology jargon ("Harness Engineering", "he-work") rather than words a user would naturally say when they need plan hardening.

Suggestions

Add natural trigger phrases to the 'Use when' clause, e.g. "Use when the user asks to tighten, de-risk, or make an implementation plan execution-ready".

Replace or gloss the jargon terms ('Harness Engineering plan hardening', 'he-work') with plain-language equivalents so the description triggers for users outside the methodology's ecosystem.

DimensionReasoningScore

Specificity

The description names the domain (implementation-plan hardening) and three concrete facets — "sequencing, verification, and risk treatment" — but rests on a single abstract verb ("Deepen") rather than a comprehensive list of concrete actions, matching the 'several specific actions with minor gaps' anchor.

4 / 5

Completeness

Both are present: the "what" ("Deepen an existing implementation plan so sequencing, verification, and risk treatment are strong enough for execution") and an explicit "Use when..." clause. Not 5 because the when-clause relies on ecosystem jargon rather than concrete natural trigger phrases a user would actually say.

4 / 5

Trigger Term Quality

"implementation plan" is a relevant natural keyword, but the triggers lean on internal jargon ("Harness Engineering", "plan hardening", "he-work") that users would not naturally say, and common variations like "tighten this plan" or "make this plan ready" are missing.

3 / 5

Distinctiveness Conflict Risk

"Harness Engineering plan hardening before he-work" carves out a clear niche tied to a specific companion skill, keeping conflict risk low; minor overlap remains with generic planning/review skills since "deepen an implementation plan" alone is broadly applicable.
