Conciseness

The body is five tight paragraphs (~200 words) with zero padding — phrases like 'historical examples do not prove availability' and 'A disconnected direct MCP server does not prove the saved connection is unavailable' deliver dense operational rules with no explanation of concepts Claude already knows. Every token carries a rule; nothing could be cut without losing guidance.

Actionability

Guidance is high-level direction — 'Discover the connection and callable tools for this session', 'Start with composed recall using the exact project/workstream scope and access envelope' — with only two concrete identifiers (`evidenceDrilldownReceipt`, the `No projection head` error) and no named tools, commands, argument examples, or callable sequences. It describes guardrails rather than giving executable steps, matching the 'minimal concrete guidance; high-level hints but missing specific steps' anchor.

Workflow Clarity

An implicit sequence exists (discover connection → composed recall → scope correction → receipt-gated drilldown → synthesis) and there are partial checkpoints ('Correct the scope on `No projection head`', 'report that gap and continue'), but steps are never listed or ordered explicitly. This sits between anchor 2 (poorly defined steps) and anchor 3 (sequence present, checkpoints implicit) — the recovery rules lift it to 3, while the lack of any explicit ordering keeps it below 4.

Progressive Disclosure

The skill is well under 50 lines with no external reference files needed, and all content appropriately lives in SKILL.md with no nested references (the assets/ images are unreferenced but harmless). The only structural gap is that the body is header-less flowing paragraphs rather than 'well-organized sections', which keeps it below the 5 the simple-skill exception allows.

Specificity

'Fan-out search across all memory sources' names the domain (prior-context memory retrieval) and one concrete action (fan-out search), but the action set stops there — no mention of synthesis, source receipts, or drilldown that the body actually performs. This matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive'); it is above anchor 2 because the action is concrete, and below anchor 4 because coverage has clear gaps.

Completeness

It explicitly answers both questions: the 'what' is 'Fan-out search across all memory sources' and the 'when' is a full 'Triggers on:' clause with concrete trigger phrases plus the catch-all 'any vague reference to past context that needs resolution before the agent can act'. This is the anchor-5 pattern ('clearly and explicitly answers both what AND when with concrete trigger phrases'), not merely the adequate-but-looser anchor 4.

Trigger Term Quality

The trigger list is comprehensive natural language users would actually say: 'from earlier', 'remember when', 'what we discussed', 'that thing with', 'did we ever', 'you mentioned', 'we talked about', 'earlier today', 'last session', 'the other day' — covering synonyms and temporal variations, exactly matching the anchor-5 example's breadth ('PDF files, PDFs, forms, document extraction, .pdf').

Distinctiveness Conflict Risk

The niche (resolving vague references to past conversation/project context) is distinct with genuinely distinctive trigger phrases ('remember when', 'last session'), so conflict risk is low — but the catch-all 'any vague reference to past context' and overlap with general memory/notes skills leaves minor collision risk, matching anchor 4 ('mostly distinct; minor overlap risk with closely related skills') rather than anchor 5's 'minimal conflict risk'.
