Conciseness

The body is imperative and lean with no concept explanations Claude already knows ("Read the relevant source files", "Verify every claim with evidence"). However, the Anti-Patterns table repeats points already made in the procedure ("Repeating the full plan in every response" duplicates step 5's 'Common mistakes'; "Say 'X should work' without checking" duplicates step 2's verification rule) — minor redundancy that could be trimmed, matching 'Efficient; minor instances of over-explanation that could be trimmed' rather than the fully lean level 5.

Actionability

As an instruction-only skill the guidance is concrete and executable: exact step behaviors ("Read the relevant source files", "Present them as clear choices with trade-offs", 2-3 options max, "stop and wait" after the final plan). It falls short of level 5 only in lacking a concrete example of the expected output (e.g., a sample findings table or decision-point format), leaving minor gaps per 'Mostly executable guidance; concrete code or commands with minor gaps'.

Workflow Clarity

The seven-step procedure is clearly sequenced with an explicit validation gate (step 7: "After presenting the final plan, stop and wait") and a feedback loop routing unconfirmed questions back to step 5 ("Ask more questions → go back to step 5"). The Anti-Patterns table functions as a checklist. This matches 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists' — the 'user confirmation' checkpoint is the appropriate validation for a non-destructive discussion skill, so the destructive-operation cap does not apply.

Progressive Disclosure

There are no bundle files (references/, scripts/, assets/ are absent) and none are needed: the body is a compact procedural guide with well-organized sections (Golden Rule, Interaction Style, numbered Procedure, Anti-Patterns) and no bulk reference material that belongs in a separate file. Content is appropriately contained in the single SKILL.md, matching the well-organized-sections standard for skills needing no external references.

Specificity

"Conduct a thorough pre-implementation discussion before making significant changes" names the domain and one main action (facilitating a discussion) but does not enumerate what the discussion covers (researching sources, mapping impact surface, presenting options with trade-offs). It matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' — below level 4, which requires several specific listed actions, and above level 2 because the action named is concrete rather than generic.

Completeness

The 'what' is explicit ("Conduct a thorough pre-implementation discussion before making significant changes") and the 'when' is explicit with concrete trigger phrases ("Use when the user wants to discuss, plan, or evaluate a change before implementing it — especially when they say words like..."). This matches the level-5 anchor: both what AND when clearly answered with concrete trigger phrases.

Trigger Term Quality

Explicit natural trigger phrases are present: "'discuss', 'evaluate', 'plan', or 'let's talk about'" — terms a user would naturally say. A few common variations are missing (e.g., 'talk through', 'brainstorm', 'what do you think about', 'before you start'), so it sits at 'Good keyword coverage; a few natural terms missing' rather than the comprehensive level 5.

Distinctiveness Conflict Risk

The pre-implementation-discussion niche is fairly clear and anchored to a distinct phase (before implementation), but trigger words like 'plan' and 'evaluate' overlap with general planning/architecture skills. This is 'Mostly distinct; minor overlap risk with closely related skills' — below level 5's 'clear niche with distinct triggers' because 'plan' is a common word many skills could claim.
