Which agents can use session-brain?: Claude, Cursor, and Codex can read a SKILL.md you add from the publisher's repository.

name: session-brain description: > Build or refresh a browser-viewable topic graph over Claude session history using local clustering. Use for mapping or clustering sessions, recent or stale topic analysis, or rebuilding/showing the session graph. Unlike wiki-history-ingest, it indexes raw sessions and never writes to the vault.

Session Brain

Builds a searchable topic graph over your agent session history. The output is a sidecar at ~/.claude/session-brain/ — the vault is never touched.

All the heavy lifting is deterministic Python in the obsidian-wiki CLI. Your only job is to name the clusters, which takes exactly one turn and requires reading no transcripts.

When to use which skill

Goal	Skill

Flag	When
`--full`	Ignore all caches and re-read everything
`--mutual`	Tighter, smaller clusters (mutual-kNN edges only)
`--half-life N`	Change the recency half-life (default 90 days)
`--min-sim 0.15`	Fewer, stronger edges — use if the graph is too dense to read
`--skip name`	Exclude a project. Match is substring-based; pass the bare name, because cache dirs start with `-` and argparse reads that as a flag
