Quality

Content

72%Weight 40%Scale 1-5

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

The content is highly actionable and the workflows are exemplary with validation checkpoints and feedback loops. However it is far too verbose for a SKILL.md, inlining deep reference material that should live in the referenced cli-reference.md, which undermines progressive disclosure.

Suggestions

Move the dense behavioral/edge-case notes (OAuth RECOVERY codes, credential-backend migration, middleware WebSocket coverage, process.run_as_user UID rules) into cli-reference.md and keep SKILL.md to overviews plus the core command examples.

Trim explanatory prose that the CLI's own --help already provides; the skill states it is authoritative, so rely on it rather than restating flag semantics.

Reduce the Quick Reference table or relocate it to the reference file so the SKILL.md body stays a navigable overview rather than a monolithic manual.

DimensionReasoningScore

Conciseness

At ~800 lines the body extensively explains gateway internals, OAuth recovery codes, credential-backend migration, and middleware WebSocket bindings that Claude could instead read via --help; substantial padding beyond what a CLI skill needs.

2 / 5

Actionability

Nearly every section gives copy-paste-ready bash commands with concrete flags and named arguments, plus a full Quick Reference table covering the common cases.

5 / 5

Workflow Clarity

Multi-step workflows (notably the Policy Iteration Loop) are explicitly sequenced with an ASCII diagram, validation via `policy list`/revision status, `--wait` exit codes, and explicit feedback loops for error recovery.

5 / 5

Progressive Disclosure

Only one external reference exists (cli-reference.md), yet the body still inlines exhaustive command details, flag tables, and behavioral notes that belong in that reference; the split is inverted from the intended overview-plus-reference structure.

Description

100%Weight 40%Scale 1-5

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

The description is comprehensive and specific, clearly stating both the capability set and explicit trigger keywords. It is detailed but earns its length through concrete command coverage. Voice is appropriately third person ('Guide agents through...').

Suggestions

The keyword list is long and reads as keyword stuffing; trimming to the highest-signal natural phrases would preserve trigger quality while reducing token cost.

DimensionReasoningScore

Specificity

Lists many concrete actions (sandbox create, sandbox exec, provider refresh, policy set/get, service expose, BYOC, inference routing), giving comprehensive coverage of the CLI's surface.

5 / 5

Completeness

Explicitly states what it does ('Guide agents through using the OpenShell CLI...') and includes explicit trigger guidance via the 'Trigger keywords' list, answering both what and when.

5 / 5

Trigger Term Quality

Includes an exhaustive keyword list spanning natural phrases ('use openshell', 'run openshell', 'manage sandbox'), CLI subcommands, and acronyms ('BYOC', 'bring your own container') that users would actually say.

5 / 5

Distinctiveness Conflict Risk

The OpenShell-specific command names and BYOC/inference niche make it clearly distinguishable from generic skills, with minimal overlap risk against other specialized skills.
