Conciseness

The body is lean and procedural: exact grep/curl/docker commands, minimal code snippets, and short 'Why' notes ('NO_PROXY bypasses the OneCLI HTTPS proxy... so they reach Ollama directly instead of going through the credential gateway') that capture non-obvious, project-specific rationale Claude could not know. No space is spent explaining general concepts; every section earns its place, matching anchor 5 rather than anchor 4's 'minor instances of over-explanation'.

Actionability

Every step is copy-paste ready: 'grep -c 'blockedHosts' src/container-config.ts src/container-runner.ts', a concrete container.json env block, an exact settings.json snippet, and docker inspect verification commands with expected output ('api.anthropic.com:0.0.0.0 in ExtraHosts'). The common case plus revert and troubleshooting are covered — a direct match for anchor 5; it cannot be 4 because there are no missing key details.

Workflow Clarity

Prerequisites, six numbered steps, a check-before-change branch ('If either count is 0, apply the changes in steps 1a and 1b'), an explicit verification step with expected results, a revert procedure, and a troubleshooting section covering failure modes (model loading cold, name mismatch, proxy bypass). That is a clear sequence with explicit validation and error-recovery feedback loops, matching anchor 5 rather than anchor 4's 'minor validation gaps'.

Progressive Disclosure

The skill bundle contains no references/, scripts/, or assets/ directories, and the body is well organized into single-load sections that all belong inline for a procedural skill. However, both the description and the body point to 'docs/ollama.md', a path that does not exist in the bundle, leaving a dangling reference — a minor organization gap consistent with anchor 4 rather than the fully resolved, well-signaled structure of anchor 5.

Specificity

Names the domain and several concrete actions — 'Route a NanoClaw agent group to a local Ollama model instead of the Anthropic API', 'just env var overrides and a model setting' — including the mechanism ('Ollama speaks the Anthropic API natively (v1/messages), so no provider code changes are needed'). Not 5 because it describes essentially one routing operation with two sub-steps rather than multiple comprehensive capabilities; not 3 because the actions named are specific and the how is explicit, exceeding '1-2 concrete actions'.

Completeness

Explicitly answers what ('Route a NanoClaw agent group to a local Ollama model... just env var overrides and a model setting') and when ('Use when the user wants to run their agent locally, cut API costs, or experiment with open-weight models') with concrete trigger phrases — a direct match for the anchor-5 example. It is above anchor 4 because the 'when' clause is explicit and specific, not merely present.

Trigger Term Quality

Contains natural phrases users would say: 'run their agent locally', 'cut API costs', 'experiment with open-weight models', 'local Ollama model', 'Anthropic API'. Good coverage but misses common variations like 'local LLM', 'self-hosted', or 'offline', so it falls just short of the comprehensive-with-synonyms anchor 5 and clearly above anchor 3's 'missing common variations'.

Distinctiveness Conflict Risk

The combination of 'NanoClaw agent group' and 'local Ollama model' carves out a clear niche with distinct triggers; virtually no other skill would fire on these phrases. Minimal conflict risk, matching anchor 5; it cannot be 4 because there is no meaningful overlap with a 'closely related skill' — the target is a specific platform and provider swap.
