Conciseness

The body is dense with codebase-specific knowledge Claude cannot know (wrapper groups, render helpers, serde conventions, e2e discover_* pattern) and explains only the 'why' behind non-obvious rules ("stdout is reserved for data so piped output isn't polluted"). Not 5 because of minor redundancy — e.g., the archetype table's reading list overlaps Step 1's per-archetype reading list, and conventions summarized in Steps 2-4 partially duplicate what is deferred to docs/adding-a-command.md.

Actionability

Highly concrete: exact file paths (src/commands/alerts/api.rs), function signatures (render_<domain>_text(merged: &MergedResults) -> Result<()>), serde attributes, and runnable commands (cargo test --test e2e -- --ignored --test-threads=1, cx schema). Not 5 because the copy-paste code templates live in docs/adding-a-command.md rather than this body, so a few steps (e.g., the fan-out loop) remain prose rather than executable code.

Workflow Clarity

A clearly sequenced 7-step workflow with a decision gate up front (Step 0 archetype table), per-archetype branching, and an explicit validation step (Step 7: cargo build/test/clippy/fmt with 'Fix any issues before committing') plus e2e and smoke-testing of all three output formats and multi-profile behavior — a full feedback loop with checklists referenced via the PR Checklist section.

Progressive Disclosure

The body is well-sectioned and consistently defers templates to a single, clearly signaled, one-level-deep reference (docs/adding-a-command.md, cited with section pointers like § "CLI Wiring" and § "Testing"). Not 5 because no bundle reference files actually ship with the skill, and a moderate amount of convention detail inlined in Steps 2-4 duplicates what the referenced doc covers — it could be pushed down to shorten the overview.

Specificity

The description names the domain precisely ("the cx CLI", "a Coralogix API", subcommands) and the core action (adding a command), but never states what the skill actually does when invoked (e.g., an end-to-end workflow covering archetype selection, API layer, wiring, tests). It sits at the 'names domain and 1-2 concrete actions, but not comprehensive' anchor — not 4 because no list of several concrete capabilities is given, not 2 because the domain and action are concrete rather than generic.

Completeness

The 'when' is answered explicitly and thoroughly ("Use this skill when the user asks to..."), but the 'what' is never explicitly stated — the reader must infer from the triggers that the skill implements a new cx command. This matches 'what' present but only implied; not 2 because the what is strongly and consistently implied by every trigger phrase rather than absent or vague.

Trigger Term Quality

Fourteen quoted natural phrases ("add a command", "new subcommand", "build a cx command", "wire up a new command", "extend the CLI", "integrate a Coralogix API") plus a catch-all ("add new functionality to the cx CLI") and an implicit-intent clause give comprehensive synonym coverage of how users would actually phrase this request.

Distinctiveness Conflict Risk

Anchoring on cx, Coralogix, and CLI subcommands carves a clear niche with minimal conflict risk. Not 5 because a few generic triggers ("add a command", "create a command", "new CLI command") could plausibly fire for other CLI projects the user is working on.
