Conciseness

The body is lean instruction-only prose with no explanations of concepts Claude already knows, but the savings-are-unknown point is repeated three times ("Savings remain unknown in every host", "Savings are unknown: the transcript has no measured comparison", "do not establish provider token or billing savings"), which could be trimmed. Fits anchor 4 rather than 5 due to this small redundancy.

Actionability

Concrete, executable guidance throughout: print the hook report "verbatim inside a fenced code block" via hookSpecificOutput.additionalContext, direct Gemini users to "/stats model" or "/stats session", and fall back to a native report or state unavailability. Minor gaps: the --all/--since 7d/--share flags are described but how the user passes them is not stated, keeping it below anchor 5.

Workflow Clarity

A simple single-purpose skill under 50 lines whose single action is unambiguous per host: print the hook-supplied report verbatim without recomputing, route Gemini to built-in /stats commands, and otherwise report unavailability. Per the simple-skill exception (no destructive or batch operations), this matches anchor 5.

Progressive Disclosure

At under 50 lines with no bundle files needed, the content is organized by host and topic with a clearly signaled one-level reference ("See docs/HONEST-NUMBERS.md"). No section headers and a bare unexplained reference to src/hooks file paths leave minor organization gaps, so anchor 4 rather than 5.

Specificity

"Show recorded output and cache-read token usage and mode attribution" and "locate the host's native usage report" list several concrete, third-person actions, with minor gaps (e.g., response counts and aggregation flags from the body are not mentioned). Not a 5 because coverage is not comprehensive; clearly above anchor 3's 1-2 actions.

Completeness

The "what" is clear (show session usage and mode attribution, or locate the host's native report) and "Trigger: /caveman-stats" is explicit trigger guidance, so the missing-'Use when' cap does not apply. Not a 5 because the trigger is command-only with no natural-language trigger phrases describing when a user needs it.

Trigger Term Quality

Natural terms like "token usage", "cache-read token usage", "usage report", and "session" are present, but common variations users would say are missing: "cost", "spend", "tokens used", "statistics". Fits anchor 3 (relevant keywords, missing variations/synonyms) rather than anchor 4's good coverage.

Distinctiveness Conflict Risk

Scoped to "the current Claude Code session" with host-specific routing (Claude Code, Gemini CLI, other hosts) and a distinct /caveman-stats trigger, making it mostly distinct. Minor overlap risk with other token-usage/stats skills keeps it below anchor 5.
