description: >-
  Recall past knowledge before working — prior decisions, solved problems, preferences,
  project history. Use at the start of any task, when the user references earlier work, when
  re-entering a project after time away, or before proposing an approach that may already
  have history. Covers query shaping, scoping, session-start catch-up, and when to escalate
  to graph exploration.

Recalling knowledge from Forgetful

Retrieval quality is decided by how the query is shaped and scoped, and by treating coverage as something to judge rather than assume. Recall before proposing; history usually exists.

Invoking operations

Operations are named by registry name (`query_memory`, `get_recent_memories`, ...). Invoke via whichever surface this agent has:

• **MCP**: `execute_forgetful_tool(tool_name="query_memory", arguments={...})`
• **CLI**: `forgetful call query_memory --args '{"query": "..."}' --json`

Get any operation's schema at runtime: `how_to_use_forgetful_tool` (MCP) or `forgetful tools info <operation>` (CLI) — schemas are deliberately not repeated here.

Step 1 — Shape the query

`query_context` is a required parameter alongside `query`; the call errors without it. The vector search embeds `query` alone. When cross-encoder reranking runs, it also uses `query_context` to refine the ranking. Include exact identifiers in `query` when they matter, but search does not guarantee literal matches.

Done when: both `query` and `query_context` are written, not just a bare keyword.

Step 2 — Scope deliberately

Reads are cross-project by default, and usually should stay that way — knowledge transfers. Narrow with `project_ids` when the task is project-bound; add `strict_project_filter=True` to also keep linked memories inside those projects (the default `False` lets links cross them). Use `importance_threshold` to cut noise — it excludes anything scored below the value given, pairing naturally with `forgetful-remember`'s rubric, where 5 is the noise floor for bulk/automated captures. Adjust `k` to trade breadth for focus. These are filters layered on top of semantic search, which stays the primary retrieval mechanism throughout.

Done when: the scope is a choice, not a default accident.

Step 3 — Judge coverage

Results are budgeted (about 8000 tokens / 20 memories), so assess coverage rather than non-emptiness:

• `truncated: true` → narrow the query (raise the threshold, scope the project) instead of

accepting silent loss.

• A miss on the first angle → re-query from a different facet (the feature area, the

technology, the error text) before concluding the knowledge doesn't exist.

Done when: results are judged sufficient, or absence is confirmed from more than one angle.

Step 4 — Expand or escalate

Promising hits get `get_memory` for full content and links. When hits arrive as fragments, reference entities, or trail across domains, the flat list is the wrong shape — switch to `forgetful-explore` and walk the graph instead.

Done when: enough context is in hand, or the exploration skill has taken over.

Step 5 — Report

This skill is the single source of truth for the retrieval reporting convention:

• Found context: "Found N memories about X" with the load-bearing ones named.
• Nothing relevant: say so explicitly — "No existing memories about X."
• Off-target results: flag them — "Retrieved some context but it seems tangential."

A clean miss is also a signal: note the gap as a `forgetful-remember` candidate once the task resolves it.

Done when: the user knows what memory contributed, even when the answer is "nothing".

Session-start catch-up

Re-entering a project after time away: `get_recent_memories` scoped to that project's ID is the catch-up move — recent decisions and milestones without guessing queries. Run it as a deliberate step, then continue into normal recall as the task demands.
