Conciseness

The ~26-line body is lean with no padding and no explanations of concepts Claude already knows — every line ("Check if `<hindsight_memories>` in the current context already contains relevant results", "use the Hindsight MCP `recall` tool") earns its place. This matches the 'lean and efficient; assumes Claude's competence' anchor.

Actionability

Guidance is concrete for an instruction-only skill: it names the exact context tag (`<hindsight_memories>`), the exact MCP tools (`recall`, `reflect`), and a specific config path (`.cursor/mcp.json`). It falls short of 5 because no example queries or argument guidance are given for `recall`/`reflect`, leaving minor gaps in how to actually invoke them.

Workflow Clarity

The 5-step workflow is clearly sequenced and includes an explicit conditional checkpoint ("If session memory already covered it, use those memories directly"), plus a conflict-handling rule in Guardrails. It is not a 5 because there is no guidance for the case where `recall` returns nothing or irrelevant results — no feedback loop for retrying or reformulating the search.

Progressive Disclosure

At under 50 lines with no need for external references (no references/, scripts/, or assets/ bundles exist), the well-organized Trigger / Workflow / Guardrails / Output sections fully satisfy the simple-skill exception for progressive disclosure. Navigation is trivial and nothing is inlined that belongs in a separate file.

Specificity

"Search long-term memory for relevant context from past coding sessions" names the domain (long-term memory, past sessions) and one concrete action (search), matching the 'names domain and 1-2 concrete actions' anchor. It is above a bare 'Processes PDF files'-style phrase because it adds a purpose, but below score 4 because only a single action is covered with no enumeration of capabilities.

Completeness

The 'what' is clear ("Search long-term memory for relevant context ... using Hindsight MCP tools") but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 2 because the 'what' is concrete and specific, not vague.

Trigger Term Quality

Keywords like "long-term memory", "past coding sessions", and "context" are relevant, but common natural variations users would say — "remember", "recall", "previously decided", "history" — are absent. This fits the 'some relevant keywords but missing common variations or synonyms' anchor rather than the comprehensive coverage of a 5.

Distinctiveness Conflict Risk

Naming "Hindsight MCP tools" carves out a clear niche distinct from generic memory or search skills, with only minor overlap risk against other memory/context skills. It falls short of a 5 because without trigger phrases like 'use when the user asks about past decisions', it could still fire for overlapping memory-related requests.
