Conciseness

The body is terse and imperative throughout ("Map the tool to code", "Packet and source first") with no explanations of concepts Claude already knows, and the domain caveats ("Target content language is not the authenticated account's UI language") are non-obvious and earn their place. It is not 5 because a few guardrails are repeated ("Do not invent a LinkedIn result", "do not invent one to complete the live check", "Do not create fake success or failure files") and the ~40 lines of generic MCP HTTP handshake boilerplate could be tightened or extracted; it is clearly above 3, which expects noticeable padding.

Actionability

Nearly everything is copy-paste ready: the argument parser ("NUM=$(echo \"$ARGUMENTS\" | sed -E ...")"), "gh issue view $NUM --repo $REPO --comments", the port-picking and 30s startup-wait loop with failure tails, the curl initialize/initialized/tools/call sequence with session-id extraction, the jq meta-file capture, and the cleanup block. It is not 5 because the tool-call template ("TOOL=\"<TOOL>\"", "ARGS_JSON='{<ARGS>}'") is never instantiated with a worked example, leaving a minor gap in covering the common case.

Workflow Clarity

The four-step sequence (Read the issue → Packet and source → Optional live check → Report) is explicit with validation at every stage: input validation with exit 1, "This step is complete when the report names the issue, the code SHA...", "If the workspace is dirty, ask before continuing", server-death and never-bound checks with log tails, session-id and protocol-error checks, and a fixed report template with a "Next" decision field. Error recovery and stop rules ("A protocol or validation error is an execution limit. Do not retry around it.") give it the feedback loops and checklist structure of anchor 5.

Progressive Disclosure

No bundle files exist and the body is well-sectioned (## 1–4 plus "## Non-negotiables") so navigation is easy and nothing is buried. It does not reach 5: the skill exceeds the ~50-line simple-skill threshold and inlines content that could live one level deep, notably the generic MCP HTTP handshake boilerplate (initialize, session-id, notifications/initialized curl blocks) that is invariant across runs; it is well above 3, which expects inline content that clearly belongs elsewhere with weak signaling.

Specificity

"Reproduce #N", "investigate #N", "try #N locally", and "verify the bug in #N" list several concrete, distinct actions. It falls short of 5 because the target of those actions is only the cryptic placeholder "#N" — the domain (GitHub issues in a specific repo) is never named, leaving a coverage gap; it is above 3, which expects only 1-2 concrete actions.

Completeness

The "what" is present ("Reproduce #N, investigate #N, try #N locally, or verify the bug in #N") but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps this dimension at 3 per the rubric guidelines. This matches anchor 3 (clear what, when missing) exactly — not 4, which requires both what and when.

Trigger Term Quality

"Reproduce", "investigate", "try ... locally", "verify the bug" are phrases a user would naturally say for this task. It sits below 5 because common synonyms and variations are missing — the words "issue", "bug report", "repro", or "triage" never appear, and "#N" is a placeholder convention rather than a natural term; it is above 3, which expects only minimal relevant keywords.

Distinctiveness Conflict Risk

"verify the bug in #N" overlaps with the sibling skill /3-verify-pr-fix (verifying a fix), and "Reproduce #N" is generic enough to fire for any repository's issues since no project is named. This is somewhat specific but could still overlap with a closely related skill, matching anchor 3; it is not 4 because the overlap risk with the sibling skill is unmitigated by any disambiguation in the description itself.
