Quality

Content

67%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 a well-structured, actionable guide to driving Signal Sciences through the Membrane CLI, with concrete commands and a clear connection-state workflow. It is held back from the top band by a redundant concept intro and a duplicated command, plus placeholder-only examples that lack a worked end-to-end run.

Suggestions

Trim the opening WAF concept paragraph and consolidate the duplicated `action list` command into a single section to tighten token efficiency.

Add one fully-worked end-to-end example with realistic values (a concrete connection id and action id) so the run/proxy flow is copy-pasteable without guessing placeholders.

DimensionReasoningScore

Conciseness

The body is mostly efficient with concrete commands, but the opening WAF concept-explanation ("a web application firewall (WAF) that protects applications...") states what Claude already knows, and the `action list` command is duplicated across "Searching for actions" and "Popular actions".

3 / 5

Actionability

It provides mostly executable, copy-paste-ready commands (install, login, connection ensure, action run, proxy) plus a flag table, with minor gaps from unfilled placeholders like `<actionId>` and `CONNECTION_ID` and no fully-worked end-to-end example.

4 / 5

Workflow Clarity

There is a clear install→authenticate→connect→poll→search→run sequence with a state-handling feedback loop (poll until READY; re-poll after CLIENT_ACTION_REQUIRED), leaving only minor validation gaps.

4 / 5

Progressive Disclosure

As a single self-contained file with no bundle files, it is well-organized into Overview / Working with Signal Sciences / Best practices sections plus a clearly signaled official-docs link; it exceeds the 50-line simple-skill threshold, so it is not a 5, but structure and placement are good.

Description

57%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 correctly names the product and includes an explicit "Use when..." trigger, satisfying the completeness floor, but relies on generic action language rather than concrete Signal Sciences capabilities. Trigger term coverage is narrow, missing the natural synonyms (WAF, Fastly, firewall) users are likely to say.

Suggestions

Replace the generic "Manage data, records, and automate workflows" with concrete Signal Sciences actions such as reviewing signals, managing rules, blocking requests, and working with sites and lists.

Expand the trigger to include natural synonyms a user would actually say, e.g. "Use when the user wants to work with Signal Sciences — its WAF signals, rules, sites, or request logs (Signal Sciences / Fastly WAF)."

DimensionReasoningScore

Specificity

"Manage data, records, and automate workflows" names the Signal Sciences domain but the actions are minimal and generic, with no concrete capabilities like blocking requests, reviewing signals, or managing rules.

2 / 5

Completeness

Both a "what" (integration, manage data/records, automate workflows) and an explicit "Use when the user wants to interact with Signal Sciences data" trigger are present, though both remain somewhat generic rather than concrete.

4 / 5

Trigger Term Quality

"Signal Sciences" and "data" are relevant natural keywords, but common variations and synonyms a user would say (WAF, Fastly, firewall rules, signals) are missing.

3 / 5

Distinctiveness Conflict Risk

"Signal Sciences" is a distinctive named product giving a clear niche with minimal conflict risk, but the generic action verbs (manage data, records) create minor overlap with adjacent integration skills.
