Conciseness

The body is lean and assumes Claude's competence (no explanations of what MCP or SSO are), but the 'Workflow' section repeats the three step headings verbatim and 'When to Use This Skill' restates the frontmatter description, so a few tokens could be trimmed. Not anchor 5 because of this minor duplication; not 3 because nothing is padded or over-explained.

Actionability

Every step is copy-paste ready: the `PROJ=$(git rev-parse ...)` snippet, the exact `red-hat-security` JSON entry with the concrete URL `https://security-mcp.api.redhat.com/mcp`, and a verbatim user-facing message for the SSO explanation. Both common cases (existing .mcp.json vs. new file) are explicitly covered, matching the anchor-5 example of fully executable guidance covering common cases.

Workflow Clarity

The three steps are clearly sequenced (locate/create → merge without removing existing servers → write back → explain auth), and the key risk is addressed ('Merge this entry into the existing mcpServers object without removing any other servers'). Not 5 because there is no post-write validation checkpoint (e.g., verifying the merged JSON parses or that existing servers survived); not 3 because the destructive risk is explicitly handled rather than left implicit.

Progressive Disclosure

A short, self-contained skill (~80 body lines) with no external references needed, organized under clear headings (Prerequisites, When to Use, Workflow, Steps 1–3, Notes). Not 5 because the Workflow overview duplicates the step headings and the Prerequisites/Dependencies sections add marginal structure — minor organization gaps consistent with anchor 4.

Specificity

It lists several specific actions — 'Add the Red Hat Security MCP server to this project', 'Configures the HTTP transport endpoint', 'explains the Red Hat Customer Portal SSO browser login flow' — in third person with no fluff. Not 5 because it omits what the server enables (CVE/advisory lookups), leaving a minor coverage gap; not 3 because three distinct concrete actions exceed the 1–2 action anchor.

Completeness

The 'what' is clear (add the server, configure HTTP endpoint, explain SSO flow), but there is no 'Use when...' clause or equivalent trigger guidance anywhere in the description, capping completeness at 3 per the judging guidelines. This is exactly anchor 3: clear 'what', 'when' missing.

Trigger Term Quality

Relevant keywords like 'Red Hat Security MCP server', 'SSO', and 'browser login flow' are present, but the natural terms a user would say when needing this skill — 'CVE', 'advisory', 'errata', 'vulnerability', 'Red Hat security data' — are absent (they only appear in the body's Notes). This matches anchor 3: some relevant keywords but missing common variations.

Distinctiveness Conflict Risk

'Red Hat Security MCP server' names a clear niche with distinct triggers (Red Hat, MCP setup, Customer Portal SSO); no other plausible skill would collide with it. Matches anchor 5: clear niche with distinct triggers and minimal conflict risk.
