fastly-cli

Executes Fastly CLI commands for managing CDN services, Compute deploys, and edge infrastructure. Use when running `fastly` CLI commands, creating or managing Fastly services from the terminal, deploying Fastly Compute applications, managing backends/domains/VCL snippets via command line, purging cache, configuring log streaming, setting up TLS certificates, managing KV/config/secret stores, checking service stats, authenticating with Fastly SSO, or working with fastly.toml. Also applies when working with Fastly service IDs in CLI context, or with `fastly service`, `fastly compute`, `fastly auth`, or any Fastly CLI subcommand. Covers service CRUD, version management, autocloning, and troubleshooting common CLI errors.

Quality

Content

92%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.

A well-structured CLI reference with highly actionable copy-paste patterns, a fully validated setup workflow, and clean progressive disclosure through a real references bundle. The only weakness is mild repetition of a few key gotchas across sections.

Suggestions

Consolidate the autoclone guidance so it is explained once (e.g. in Common Flag Examples) and only briefly referenced elsewhere, to remove redundancy.

Trim conversational padding such as 'waste time cloning manually' to keep the body token-lean.

The 'Covers:' line under Trigger and scope largely duplicates the References table and description; consider collapsing it to avoid restating the same scope twice.

DimensionReasoningScore

Conciseness

Mostly lean and dense with valuable CLI-specific gotchas, but a few points are repeated across sections (autoclone appears in Key Patterns, Common Flag Examples, and inline) and minor phrases like 'waste time cloning manually' could be trimmed.

4 / 5

Actionability

Copy-paste-ready commands with explicit CORRECT/WRONG contrast (boolean flags, domain --name, host header override) and concrete flags throughout, covering the common cases directly.

5 / 5

Workflow Clarity

The 'New VCL Service Setup Workflow' is a 6-step sequence with explicit validation checkpoints (version validate, propagation verify), expected outcomes, and error-recovery feedback loops for the destructive activation steps.

5 / 5

Progressive Disclosure

A clear References table maps each topic to a real one-level-deep file in references/ with a 'Use when...' column, and the body stays an overview that points to those files for detail; all referenced files exist.

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.

A strong, well-scoped description that clearly states capabilities and an explicit 'Use when' trigger clause with abundant natural trigger terms. It is comprehensive without resorting to vague buzzwords.

DimensionReasoningScore

Specificity

Lists many concrete actions (Compute deploys, backends/domains/VCL snippets, cache purging, log streaming, TLS certs, KV/config/secret stores, stats, SSO auth) with comprehensive coverage and no vague filler.

5 / 5

Completeness

Explicitly answers both 'what' ('Executes Fastly CLI commands for managing CDN services, Compute deploys, and edge infrastructure') and 'when' ('Use when running fastly CLI commands...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Covers natural trigger phrasing users would say ('running fastly CLI commands', 'fastly service', 'fastly compute', 'fastly auth', 'fastly.toml', 'Fastly service IDs') plus subcommand synonyms and file-name triggers.

5 / 5

Distinctiveness Conflict Risk

Scoped tightly to the Fastly CLI with Fastly-specific triggers (fastly.toml, fastly service/compute/auth), giving it a clear niche and minimal conflict risk with other skills.
