Conciseness

The body assumes Claude's competence throughout — it never explains what MCP, OAuth, or a CLI is — and every table and command carries operational fact. A few passages could still be trimmed (e.g. the long wiring paragraph in the readiness check), which matches the 4 anchor (efficient, minor over-explanation) rather than the perfectly lean 5 anchor.

Actionability

Guidance is copy-paste ready: "npx mcporter list | grep cloudbase", "npx mcporter call cloudbase.queryEnv action=list --output json", a complete mcporter.json config block, exact endpoints, an env-variable table, and concrete tool/action names (auth(action="status"), manageStorage, deployBuild). Specific examples cover the common cases, matching the 5 anchor.

Workflow Clarity

The readiness check is a clearly sequenced triage: four numbered failure modes, a state→call→expected-result table, explicit validation ("require auth_status: READY plus the expected current_env_id before any cloud write"), and feedback loops ("follow next_step", reconnect_plugin, auth(action="set_env")). Explicit checkpoints and error recovery place it at the 5 anchor, not 4.

Progressive Disclosure

The body is a well-organized overview with clearly signaled one-level-deep references: references/issue-report.md exists in the bundle and is cited with when-to-read guidance, and bulk MCP setup detail is correctly split out to ../cloudbase/references/mcp-setup.md rather than inlined. Navigation is easy and the missing-sibling case is handled explicitly, matching the 5 anchor.

Specificity

The description enumerates multiple concrete actions — "connecting local or remote MCP", "calling tools from the shell with mcporter", "reading tool schemas", "setting site, region, cloud mode, or plugin flags", "contributing a fix to the open-source MCP server" — with comprehensive coverage of the skill's domain. It sits at the 5 anchor rather than 4 because no meaningful capability area is missing.

Completeness

Both parts are explicit: the what ("CloudBase MCP reference" plus the enumerated task areas) and a clear "Use when…" clause listing concrete triggers. It is not a 4 because the when-guidance is already explicit and specific, matching the 5 anchor's requirement for concrete trigger phrases.

Trigger Term Quality

Good natural keyword coverage ("connect MCP", "mcporter", "tool schemas", "endpoint", "site, region, plugin flags"), but a few natural terms users would say are absent — e.g. the "tcb"/"TCB" CLI name and "CloudBase tools" outside the product label. This matches the 4 anchor (good coverage, a few natural terms missing) rather than 5 (comprehensive including synonyms).

Distinctiveness Conflict Risk

Triggers are highly niche ("mcporter", "domestic or international endpoint", "open-source MCP server, skills, or CLI") and would not fire for unrelated skills. This fits the 5 anchor (clear niche, minimal conflict risk); no neighboring anchor fits better.
