Conciseness

The body is lean and domain-specific throughout — no explanations of concepts Claude already knows, and directives like 'do not silently rebuild' and 'Never read one whole' are operationally earned. Not a 5: a few spots could be trimmed, e.g. the aside 'This is why a session that never said "telemetry" can still surface for it' and 'Two things must be stated honestly rather than glossed over' spend tokens restating what the surrounding bullets already imply; not a 3 because there is no genuinely unnecessary explanation or padding.

Actionability

Every step ships executable material: 'obsidian-wiki sessions-query "<topic>" --json', the filter flags (--project, --cluster, --since, --top), 'obsidian-wiki sessions-show <session-id> --pretty', and a copy-paste-ready python snippet for filtering human turns from JSONL, plus a 'grep -c' size pre-check. Guidance covers the common cases including the fallback when loader skills are absent — matching 'fully executable; copy-paste ready; specific examples cover the common cases'.

Workflow Clarity

Steps 1-5 are clearly sequenced with explicit checkpoints and feedback loops: exit-1 handling for a missing graph in Step 1, stale-graph detection with a user-consent gate, handling of 'loadable: false' / all-unloadable cases in Step 3, a conditional fallback in Step 4 when personal skills don't exist, and a cite-your-sources requirement in Step 5. The skill is read-only, so no destructive-operation cap applies; this matches 'clear sequence with explicit validation steps; feedback loops for error recovery'.

Progressive Disclosure

A single-file skill with well-organized step sections, a 'Related' section that clearly distinguishes sibling skills (/session-brain, wiki-query, wiki-agent), and no nested or buried references — everything referenced (commands, skills) is one level deep. Not a 5: at ~90 body lines it exceeds the under-50-line simple-skill threshold, and some detail (the four ranking-signal explanations and the transcript-filtering recipe) could plausibly live in a reference file to keep the overview leaner; not a 3 because structure is clean and navigation is easy.

Specificity

The description names the domain ('session-brain graph', 'past agent session by topic') and exactly two concrete actions — 'Search the session-brain graph... by topic' and 'load the winning transcript into the current conversation' — matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. Not a 4: the supporting steps (ranking, presenting results, filtering) are absent, so coverage has minor gaps beyond the two stated actions; not below 3 because both actions are concrete and explicitly scoped ('Read-only; requires a session-brain graph').

Completeness

It explicitly answers 'what' ('Search the session-brain graph... and load the winning transcript into the current conversation') and 'when' with concrete trigger phrases ('Use for finding which session handled X, when Y was last worked on, or whether this was done before'), directly matching the anchor-5 good example. Both halves are present, explicit, and trigger-phrased, so 4's 'when could be more explicit' does not apply.

Trigger Term Quality

'Use for finding which session handled X, when Y was last worked on, or whether this was done before' provides natural user phrasings ('which session handled', 'last worked on', 'was this done before') plus terms like session, transcript, topic. Not a 5: common synonyms users might say — 'chat history', 'conversation history', 'previous session' — are only partially covered; not a 3: keyword coverage is genuinely good with natural phrase-shaped triggers, not just domain jargon.

Distinctiveness Conflict Risk

It carves a clear niche — searching a specific 'session-brain graph' for past agent sessions, explicitly noting it 'requires a session-brain graph' — with triggers ('which session handled X', 'whether this was done before') unlikely to fire for generic search or wiki skills. Minimal conflict risk; the anchor-5 'clear niche with distinct triggers' fits.
