Conciseness

The body is information-dense and avoids explaining basic concepts Claude already knows, but the 'courier, not a co-author' / hook-blocked / verbatim-relay doctrine is restated across the intro, 'Output contract', 'Hook-blocked tool calls', and 'Where the tool's stdout actually lives' sections with overlapping examples — noticeably more than minor trimming. It is not a 4 because the redundancy is repeated across multiple sections rather than isolated instances, and not a 2 because the content is genuinely useful and not padded with elementary explanations.

Actionability

Provides copy-paste-ready, fully executable commands for all four CLIs (e.g. `claude -p "<prompt>"`, `opencode run`, `cursor-agent -p --trust`, `codex exec`), a complete parallel `wait` block, and concrete fixes like `CLAUDECODE="" claude -p`. Placeholders for model IDs are justified by the explicit discovery guidance, so it is not a 4.

Workflow Clarity

The 4-step workflow (Parse intent → Pick model → Build & run → Present) is clearly sequenced, and the 'Self-check before sending the final message' section is an explicit validation checklist with error-recovery guidance (auth failures, native-first no-silent-fallback, missing binary). It is not a 4 because explicit validation steps and a checklist are present rather than merely implied.

Progressive Disclosure

The body is well-sectioned and offloads bulk detail to two real, one-level-deep, clearly-signaled reference files ([references/models.md], [references/runtimes.md]), keeping only a quick-start cheatsheet inline. It is not a 4 because navigation is clean and the reference split is appropriate rather than having only minor organization gaps.

Specificity

Names the domain ('Run prompts in Claude Code, OpenCode, Cursor, or Codex CLIs') and several concrete actions (run one IDE, fan-out, model comparison, relay stdout verbatim), listing multiple specific actions with only minor coverage gaps. It is not a 5 because 'relay stdout verbatim' reads more as a constraint than a capability, and not a 3 since it clearly enumerates more than 1-2 actions.

Completeness

Explicitly answers both what ('Run prompts in ... CLIs ... Relay the other runtime's stdout verbatim') and when ('Use on run in <ide>, compare <ide> vs <ide>, try on <model>, run across models') with concrete trigger phrases. The 'Use on...' clause satisfies the explicit-trigger-guidance requirement, so it is not capped at 3 and clearly fits the 5 anchor.

Trigger Term Quality

Provides natural trigger phrasings via 'Use on run in <ide>, compare <ide> vs <ide>, try on <model>, run across models' alongside the named CLIs, giving good keyword coverage. It is not a 5 because the placeholders (<ide>, <model>) stand in for concrete synonyms and file extensions rather than enumerating them, and not a 3 because the trigger phrases are clearly natural user language.

Distinctiveness Conflict Risk

The niche — running prompts in four named IDE CLIs and relaying their output verbatim from this session — is highly distinct with minimal overlap risk against other skills. It is not a 4 because there is no meaningful overlap with closely related skills; the courier/verbatim framing carves out a clear, non-conflicting niche.
