What it does

Session Search is an agent skill from Ar9av/obsidian-wiki. Search the session-brain graph for a past agent session by topic and load the winning transcript into the current conversation. Use for finding which session handled X, when Y was last worked on, or whether this was done before. Read-only; requires a session-brain graph.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management. The repository describes itself as: Framework for AI agents to build and maintain a digital brain through Obsidian wiki | Memory System for Agents. The licence is MIT.

Answer

What it can do on your machine

Read from SKILL.md and the folder at commit 709727e. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Session Search loads about 946 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 456 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~72
When it runs · the whole SKILL.md, loaded when a task matches: ~946

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: session-search
description: Search the session-brain graph for a past agent session by topic and load the winning transcript into the current conversation. Use for finding which session handled X, when Y was last worked on, or whether this was done before. Read-only; requires a session-brain graph.

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.

Show full SKILL.md (187 more words)Show less

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.

/session-brain — build or refresh the graph, survey and name topics
wiki-query — search compiled vault knowledge; this skill searches raw session history instead
wiki-agent — pull a topic out of another agent's history and distil it into the vault
