session-brain

Build and maintain a topic graph over your agent session history. Reads every Claude session transcript plus the pruned sessions that survive only in history.jsonl, clusters them by topic using local TF-IDF (no API calls, no embeddings), and writes an interactive graph you can open in a browser. Use when the user says "/session-brain", "build my session map", "cluster my claude sessions", "map my session history", "rebuild the session graph", "show me my session graph", "what have I been working on lately", "what topics have gone stale". Different from wiki-history-ingest, which distils sessions into vault pages: this builds a retrieval index over the raw sessions and never writes to the vault.

Quality

Content

90%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean, fully actionable walkthrough of a single CLI with a clear three-step workflow and useful verification/recovery guidance. It loses a point on workflow clarity (no explicit validate→fix→retry framing) and progressive disclosure (slightly over the simple-skill line with an inline flags table), but is otherwise strong.

Suggestions

Add an explicit validation checkpoint after Step 1, e.g. 'If cluster count or edge count looks unreasonable, rerun with --full before naming clusters' — a clear validate→fix→retry loop would lift workflow_clarity to 5.

Consider moving the Step 1 flags table into a references/FLAGS.md file referenced one level deep, which would tighten the main body and lift progressive_disclosure.

State the expected output location of clusters.json / names.json up front in Step 1 so the reader knows where intermediate artifacts land before Step 3 reads them.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it gives commands and flag tables without explaining what TF-IDF, embeddings, or clusters are, and every prose note (e.g. names keyed by vocabulary so they survive rebuilds) earns its place; not below 5 because there is no padding to trim.

5 / 5

Actionability

Fully executable, copy-paste-ready commands throughout — 'obsidian-wiki sessions-build --json', 'obsidian-wiki sessions-clusters --unnamed --json', the sessions-name heredoc with a concrete JSON example, and 'open ~/.claude/session-brain/graph.html' — covering the common build/name/report cases.

5 / 5

Workflow Clarity

A clear three-step sequence (Build → Name → Report) with checkpoints present (report headline numbers in Step 1, report the map in Step 3, '--full rebuilds from scratch' recovery hint in Notes); not 5 because there is no explicit validate→fix→retry loop framing, and not below 4 because verification steps are present so the batch-operation cap at 3 does not apply.

4 / 5

Progressive Disclosure

Well-organized into titled sections (comparison table, Step 1/2/3, Notes) with all content appropriately inline for a single-CLI skill and no nested or buried references; not 5 because, at ~88 lines, it slightly exceeds the under-50-line simple-skill exception and holds a flags table inline that could be split out, though it is small enough to be reasonable inline.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: it states concrete capabilities in third person, gives a rich set of natural trigger phrases, answers both 'what' and 'when' explicitly, and explicitly distinguishes the skill from a neighboring one. No vague fluff or over-claims are present.

DimensionReasoningScore

Specificity

Lists multiple concrete actions in third person — 'Build and maintain a topic graph', 'Reads every Claude session transcript plus the pruned sessions...clusters them by topic using local TF-IDF', 'writes an interactive graph you can open in a browser' — matching the comprehensive-coverage anchor; not below because coverage is broad and specific, not above because 5 is the ceiling.

5 / 5

Completeness

Explicitly answers both 'what' (build/maintain a topic graph via local TF-IDF, write an interactive graph) and 'when' ('Use when the user says...') with concrete trigger phrases, matching the top anchor; no missing element to push it below.

5 / 5

Trigger Term Quality

Provides many natural trigger phrases users would say — '/session-brain', 'build my session map', 'cluster my claude sessions', 'map my session history', 'what have I been working on lately', 'what topics have gone stale' — covering synonyms and the literal command, matching the comprehensive-coverage anchor.

5 / 5

Distinctiveness Conflict Risk

States a clear niche and explicitly differentiates from the adjacent skill — 'Different from wiki-history-ingest, which distils sessions into vault pages: this builds a retrieval index over the raw sessions and never writes to the vault' — giving distinct triggers and minimal conflict risk.
