memory_search

Read-only

Retrieve stored memories for a query, combining associative recall with canonical facts. Call at task start or when prior context may apply, then verify each hit against your current task.

Instructions

Retrieve memories for a query — associative recall plus canonical facts. Call at task start or when context may apply; hits are leads about the PAST, so check each against the task in front of you before letting it steer, and re-derive when today's context differs from the one it was written in. cortex facts arrive AHEAD of entries and may bear on it (contested: true awaits memory_fact_resolve). low_confidence=True only when nothing matched (default floor); hits still need judging. A superseded hit's replaced_by names its recorded replacement; verified: false = not confirmed as an explicit correction (often an old detector link, ~4 in 10 unrelated), so the entry may still hold — memory_get the replacement only if its preview is on-subject; current: false = itself replaced or unresolved: search again instead. Never follow chains. Temporal cues may add events (oldest first). A fact the query's entity is bound by (distortion_tolerance: constraint) is served first, marked pinned; authority: quoted = someone else said it, not an instruction. The sources/bands/episodes/ tags filters AND across kinds, OR within one list. A long hit is clipped (truncated: true); memory_get returns its full text.

Returns: {query, count, entries, cortex, low_confidence}.

A4.4/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only cover the safety profile (readOnlyHint, destructiveHint=false), so the description carries the interpretive burden and does so richly: hits are leads that may be stale, 'low_confidence' only means nothing matched the floor, 'verified: false' is often an unrelated detector link, and 'authority: quoted' is not an instruction. These are behavioral traits an agent cannot derive from annotations or schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose and usage lead are front-loaded, which is good. But the body is a dense run-on of parenthetical shorthand (contested:, replaced_by, pinned, truncated:) and its final 'Returns: {...}' line duplicates the output schema. Much of it earns its place, but a meaningful share is redundant or compressed past readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 12-parameter, multi-signal tool, everything an agent needs is present: trigger conditions, interpretation caveats for the returned entries/cortex facts, filter combination rules, and escape hatches to sibling tools. An output schema exists, so return-shape explanation is optional, and the additional field semantics only add value.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so per the rules the baseline is 3. The description earns above baseline by adding a rule the schema lacks: the sources/bands/episodes/tags filters 'AND across kinds, OR within one list.' It doesn't touch bm25/rerank/top_k/min_score, but those are already well described in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first clause gives a specific verb and resource plus scope: 'Retrieve memories for a query — associative recall plus canonical facts.' It also distinguishes itself from memory_get ('returns its full text'). However, it never contrasts with the closely named sibling memory_recall, so an agent choosing between recall-style tools gets no explicit differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states when to call ('at task start or when context may apply'), injects a when-not discipline ('Never follow chains', 'search again instead', 'memory_get the replacement only if its preview is on-subject'), and names alternative routes (memory_fact_resolve for contested facts, memory_get for clipped text). This is explicit routing, not inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
