Conciseness

The body is lean and telegraphic with zero padding: "Resolve exactly one canonical mode", "Idempotent: a second run leaves exactly one entry per event", "Silence, elapsed time and tool errors are not approval". It assumes Claude's competence and never explains concepts Claude already knows; every token earns its place.

Actionability

The mode table gives concrete per-mode effects and the resolution rules are specific, but the actual execution details are missing: no commands, file contents, or hook-registration mechanics for how to "Register the SessionStart and UserPromptSubmit handlers" or what to write to `.codex/brewtools/manager/state.json`. This is "Some concrete guidance but incomplete... missing key details" rather than anchor 4's mostly-executable guidance.

Workflow Clarity

The mode-resolution logic and safety gates are explicit ("Obtain confirmation before global writes", purge must "state exactly what will be deleted before running it"), but there is no ordered end-to-end sequence and no post-action verification step (e.g., checking registration after install). This matches "Steps listed but validation gaps; sequence present but checkpoints missing or implicit" rather than anchor 4, which expects most checkpoints explicit.

Progressive Disclosure

The bundle contains seven reference files (full.md, planmode.md, architect.md, review-double.md, review-regression.md, cron.md, cron-plan.md) but the body never names or links any of them — the closest it comes is the vague "using the plan-aware reference in plan mode". References are present but not clearly signaled, matching "Some structure but... references present but not clearly signaled"; it is above anchor 2 because the body itself is well-sectioned and nothing that belongs in a separate file is inlined.

Specificity

"Configures Manager and review prompt modes" names the domain but offers only one generic action, matching "Names the domain but actions are minimal or generic" (cf. "Processes PDF files"). The concrete verbs the skill actually performs (install, enable, disable, purge) never appear, so it does not reach the 1-2 concrete actions of anchor 3.

Completeness

The "what" is stated ("Configures Manager and review prompt modes") but the "when" is only weakly implied by "Explicit user invocation only", which is a negative constraint rather than an explicit "Use when..." trigger clause. Per the judging guidelines a missing 'Use when...' clause caps completeness at 3; it is above anchor 2 because a clear what is present.

Trigger Term Quality

Only "Manager" and "review" serve as keywords, and the natural phrases a user would actually say ("manager mode", "++m", "prompt mode", "install the manager") are absent. This fits "One or two generic keywords; missing the natural phrases users say" better than anchor 3, which expects broader relevant keyword coverage.

Distinctiveness Conflict Risk

"Manager" is a distinct niche term, but "review prompt modes" overlaps with common review-related skills a user might invoke, so it "could still overlap with similar skills". The "Explicit user invocation only" guard reduces risk, but not enough for anchor 4's "minor overlap risk" given how broad "review" is.
