# Session Search
Answers "which of my past sessions was about X" and then pulls that session's context in.
## Step 1: Check the graph exists and is fresh
```bash
obsidian-wiki sessions-query "<topic>" --json
```
If this exits 1 with "run sessions-build first", tell the user and offer `/session-brain`. If
`graph.json` is more than ~7 days old, mention it and offer a rebuild — but **do not silently
rebuild**, since that is a multi-second operation the user did not ask for.
## Step 2: Rank
The scoring already combines four signals, so take the ordering as given rather than re-ranking:
- **similarity** — TF-IDF cosine against the session's text
- **cluster lift** — a session inside the best-matching topic scores higher even if its own words
never matched. This is why a session that never said "telemetry" can still surface for it.
- **bookmark boost** — a human already flagged this session as worth keeping
- **time decay** — 90-day half-life, applied with a floor so an old exact match still outranks a
fresh weak one
Useful filters: `--project NAME`, `--cluster N`, `--since DATE`, `--top N`.
## Step 3: Present
Show the top ~5 as a compact table — title, project, date, topic, and the `why` string, which
already explains the match. Do not dump the raw JSON at the user.
Two things must be stated honestly rather than glossed over:
- Entries with `loadable: false` are **history-only**: the transcript has been pruned from disk
and only the prompts survive. They are listed in `unloadable` with a reason. Say the transcript
is gone; do not imply it can be retrieved.
- If everything relevant is unloadable, answer from the prompt text that *is* there and say that
is all that remains.
## Step 4: Load — hand off, do not reimplement
`should_load` holds at most 3 session ids worth opening, already filtered to ones with
transcripts.
**Prefer an existing loader skill if the user has one installed:**
- `claude-session-load` — loads a Claude session by id
- `bookmark-load` — use when the hit is bookmarked
⚠️ Those skills live in the user's personal skills directory (`~/.claude/skills/`), **not in this
repo**. They may not exist. Do not assume them and do not error if they are absent — fall back to
reading the transcript directly:
```bash
# the path is in the query result as `transcript`
obsidian-wiki sessions-show <session-id> --pretty
```
The transcript is JSONL and can be tens of MB. **Never read one whole.** Filter to the human turns
first:
```bash
grep -c '' <transcript> # size check before anything else
python3 -c "
import json,sys
for line in open(sys.argv[1], errors='replace'):
try: r = json.loads(line)
except ValueError: continue
if r.get('type')=='user' and not r.get('isSidechain') and not r.get('isMeta'):
c = (r.get('message') or {}).get('content')
if isinstance(c,str) and not c.lstrip().startswith('<'): print('>', c[:400])
" <transcript>
```
## Step 5: Answer
Synthesise from what you loaded and cite the session ids you used. If the answer came from a
history-only session's prompts rather than a real transcript, say so — the user needs to know how
much of the context you actually have.

Install targets
Codex install prompt
Install the "session-search" agent skill from https://github.com/Ar9av/obsidian-wiki/tree/main/.skills/session-search. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Find a past agent session by topic and load its context into the current conversation. Searches the session-brain topic graph, ranking by relevance, topic membership, and time decay, then loads the winning transcript. Use when the user says "/wiki-sessions <topic>", "which session did I do X in", "find the session where I fixed X", "when did I last work on Y", "what was that session about Z", "load the session where I set up X", "have I done this before". Read-only — never writes to the vault. Requires a graph built by the session-brain skill. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"ar9av-session-search","task":"Install session-search","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: .skills/session-search/SKILL.md. Recorded revision: 3f29e56d0ba9a175d7c87b3bb2e99b9cddd2b11a. Confirm the source matches these instructions.
