Memory Search

Search past work across all sessions. Simple workflow: search -> filter -> fetch.

When to Use

Use when users ask about PREVIOUS sessions (not current conversation):

• "Did we already fix this?"

• "How did we solve X last time?"

• "What happened last week?"

3-Layer Workflow (ALWAYS Follow)

NEVER fetch full details without filtering first. 10x token savings.

Step 1: Search - Get Index with IDs

Use the search MCP tool:

search(query="authentication", limit=20, project="my-project")

Returns: Table with IDs, timestamps, types, titles (~50-100 tokens/result)

Parameters:

• query (string) - Search term

• limit (number) - Max results, default 20, max 100

• project (string) - Project name filter

• type (string, optional) - "observations", "sessions", or "prompts"

• obs_type (string, optional) - Comma-separated: bugfix, feature, decision, discovery, change

• dateStart (string, optional) - YYYY-MM-DD or epoch ms

• dateEnd (string, optional) - YYYY-MM-DD or epoch ms

• offset (number, optional) - Skip N results

• orderBy (string, optional) - "date_desc" (default), "date_asc", "relevance"

Step 2: Timeline - Get Context Around Interesting Results

Use the timeline MCP tool:

timeline(anchor=11131, depth_before=3, depth_after=3, project="my-project")

Or find anchor automatically from query:

timeline(query="authentication", depth_before=3, depth_after=3, project="my-project")

Returns: depth_before + 1 + depth_after items in chronological order with observations, sessions, and prompts interleaved around the anchor.

Parameters:

• anchor (number, optional) - Observation ID to center around

• query (string, optional) - Find anchor automatically if anchor not provided

• depth_before (number, optional) - Items before anchor, default 5, max 20

• depth_after (number, optional) - Items after anchor, default 5, max 20

• project (string) - Project name filter

Step 3: Fetch - Get Full Details ONLY for Filtered IDs

Review titles from Step 1 and context from Step 2. Pick relevant IDs. Discard the rest.

Use the get_observations MCP tool:

get_observations(ids=[11131, 10942])

ALWAYS use get_observations for 2+ observations - single request vs N requests.

Parameters:

• ids (array of numbers, required) - Observation IDs to fetch

• orderBy (string, optional) - "date_desc" (default), "date_asc"

• limit (number, optional) - Max observations to return

• project (string, optional) - Project name filter

Returns: Complete observation objects with title, subtitle, narrative, facts, concepts, files (~500-1000 tokens each)

Examples

Find recent bug fixes:

search(query="bug", type="observations", obs_type="bugfix", limit=20, project="my-project")

Find what happened last week:

search(type="observations", dateStart="2025-11-11", limit=20, project="my-project")

Understand context around a discovery:

timeline(anchor=11131, depth_before=5, depth_after=5, project="my-project")

Batch fetch details:

get_observations(ids=[11131, 10942, 10855], orderBy="date_desc")

Why This Workflow?

• Search index: ~50-100 tokens per result

• Full observation: ~500-1000 tokens each

• Batch fetch: 1 HTTP request vs N individual requests

• 10x token savings by filtering before fetching
