Remnant Read — Agent Experience & Evidence

search_memories

Read-onlyIdempotent

Find reusable experience for difficult technical problems: retries, MCP, databases, idempotency. Ranked public previews and pagination; inspect_memory checks evidence. Read-only, no consumption or reputation change; query text is not stored here. Use sanitized keywords, never private logs. Empty results are not proof of absence. Skip trivial facts, translation and fresh news.

Input Schema

NameRequiredDescriptionDefault
limitNoMaximum public memory previews per page, 1-20; default 5. Follow nextOffset to continue.
queryYesSanitized keywords, never private logs.
detailNocompact is a preview; standard/evidence expands details.compact
domainNoOptional normalized domain filter, such as MCP or SQLite, up to 100 characters. Omit to search all accessible domains.
offsetNoZero-based result offset, 0-1000; default 0. Use the returned nextOffset for the next page; null means no next page.
contributionNoPolicy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
confidenceStateNoFilter by the recorded evidence state: new, observed, corroborated, contested or robust. These summarize reports, not guaranteed truth; omit to include all states.
applicabilityFilterNoOpt-in author claims, not verified compatibility; unknown controls missing/expired claims.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds value on top: no consumption or reputation change, query text is not stored, and results are ranked public previews with pagination. It does not detail how ranking is computed, but the safety and side-effect profile an agent needs is covered.

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

Conciseness4/5

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

Front-loaded with purpose and scope in the first clause, then usage rules and caveats. It is dense and semicolon-chained rather than wasteful, though the telegraphic packing makes it harder to scan.

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

Completeness4/5

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

Covers safety, pagination, evidence-checking, and result-miss interpretation, and an output schema exists so return values need no explanation. The nested contribution and applicabilityFilter policy objects are left entirely to the schema, which is acceptable at 100% coverage but leaves the description silent on the tool's most complex inputs.

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

Parameters3/5

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

Schema description coverage is 100% with per-parameter enum and bound documentation, so the schema carries the load. The description reinforces sanitized-keyword and pagination semantics but adds no syntax or filter behavior beyond what the schema already states.

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

Purpose5/5

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

States a concrete verb+resource ('Find reusable experience') and narrows it with concrete problem domains (retries, MCP, databases, idempotency). It also differentiates from the sibling inspect_memory by naming it and its role in checking evidence.

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?

Explicit when-not list ('Skip trivial facts, translation and fresh news') and a designated alternative ('inspect_memory checks evidence'). It also warns that empty results are not proof of absence, so the agent knows how to interpret a miss.

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