memory_guard_after

Record a completed tool action against its preflight receipt to validate evidence, store redacted input/output traces, and update the agent's memory for future guard decisions.

Input Schema

cwdNoWorking directory at the time of the action.
toolNoTool or command family that completed, e.g. Bash, npm test, Edit, deploy.
filesNoFile paths to fingerprint (size + mtime + content hash).
inputNoTool input. Hashed and never stored raw; redacted metadata is only stored when retain_details is true.
outputNoTool output. Same redaction and storage policy as input.
outcomeNoOutcome classification
metadataNoArbitrary structured metadata (redacted before storage).
receipt_idYesReceipt id returned by memory_guard_before.
session_idNoSession identifier for grouping related guard events.
error_summaryNoShort error description if the action failed. Redacted and truncated to 2 KB.
retain_detailsNoIf true, redacted input and output payloads are stored alongside hashes. Defaults to false.

TDQS

D1/5.0
Behavior1/5

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

Tool has no description.

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

Conciseness1/5

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

Tool has no description.

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

Completeness1/5

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

Tool has no description.

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

Parameters1/5

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

Tool has no description.

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

Purpose1/5

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

Tool has no description.

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

Usage Guidelines1/5

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

Tool has no description.

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