customize

Create, configure, and maintain custom agent profiles and author new skills via the `repl` tool. Use when the user wants to create an agent profile, build a custom agent, modify agent capabilities, attach or detach skills/connectors on a profile, author a skill, or inspect which connectors and tools are available. Also use whenever you need the `host.agents.*` or `host.skills.*` Python SDK.

Quality

Content

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Highly actionable with a clear, validated workflow, but the body is long and repeats the profile-mode/connector logic across sections while keeping detailed reference material inline rather than in separate files. Tightening the repetition and splitting the SDK/kernel reference into bundled files would raise the two weaker dimensions.

Suggestions

Consolidate the unrestricted-vs-curated / skill_names / connector-reach explanation into one place; the workflow steps can reference it instead of restating it three to four times.

Move the detailed host.agents/host.skills SDK signature reference and the kernel sidecar deep-dive into bundled reference files (e.g. references/sdk-reference.md, references/kernel-sidecars.md) and link to them from SKILL.md to improve progressive disclosure.

Trim restated guidance in workflow steps 5 and 6 that duplicates the intro 'Connector access' and SDK 'create'/'update' notes.

DimensionReasoningScore

Conciseness

The content is largely necessary platform-specific knowledge Claude does not already have, but the unrestricted/curated profile, skill_names, and connector-reach logic is restated across the intro, the SDK reference, and workflow steps 3/5/6, so it could be tightened; not a 1 because it does not pad with general concepts, not a 3 because of the repetition and length.

2 / 3

Actionability

Provides fully executable guidance: real host.agents/host.skills signatures, return-shape comments, the safe update-on-unrestricted pattern, attach_connector pattern usage, and runnable kernel.py examples — copy-paste ready.

3 / 3

Workflow Clarity

The scope→draft→review→create workflow is numbered 1–7 with explicit validation read-backs ("read back host.agents.list()", "read back host.agents.get(name)[\"connectors\"]"), an ask_user review gate, and error-recovery notes (CalledProcessError.stderr, iterate against sidecar_gate).

3 / 3

Progressive Disclosure

Sections are well organized and the skill-creator offload is well signaled, but no bundle/reference files exist and ~450 lines of detailed SDK reference and kernel-sidecar content are inline in a single SKILL.md rather than split into one-level-deep reference files; the under-50-line simple-skill exception does not apply.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that concretely states capabilities, gives explicit 'Use when...' triggers covering natural user phrasings, and carves out a distinct niche. No changes needed.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ("Create, configure, and maintain custom agent profiles and author new skills" plus "create an agent profile, build a custom agent, modify agent capabilities, attach or detach skills/connectors... author a skill"), matching the anchor-3 example; voice is verb-first/third-person with no first- or second-person penalty.

3 / 3

Completeness

Explicitly states both what ("Create, configure, and maintain custom agent profiles and author new skills via the repl tool") and when ("Use when the user wants to... Also use whenever you need..."), satisfying the anchor-3 what-and-when bar with explicit triggers.

3 / 3

Trigger Term Quality

Natural terms a platform user would say are well covered ("create an agent profile, build a custom agent, attach or detach skills/connectors, author a skill, inspect which connectors and tools are available"), plus the SDK trigger "whenever you need the host.agents.* or host.skills.* Python SDK".

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (meta-management of agent profiles and skills via the repl/host SDK) with distinct triggers unlikely to fire for unrelated skills.
