verify_export

Read-onlyIdempotent

Verify a signed PhaseFolio export by content hash. Returns verification status (valid/tampered/unknown), issued timestamp, methodology version, and an anonymized originating-org identifier. Use this when a user shares a PhaseFolio asset snapshot and you want to confirm it's authentic before citing the analysis.

Input Schema

NameRequiredDescriptionDefault
hashYes64-character hex SHA-256 of the signed artifact's content. Embedded in every signed PhaseFolio PDF (footer) and Excel (cover tab).

  4. First observed

TDQS

A4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds the three verification outcome states (valid/tampered/unknown), which is some extra semantic context, but since an output schema exists this is largely redundant and it says nothing about auth, rate limits, or failure behavior.

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

Conciseness5/5

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

Two tight sentences: the mechanism and return payload come first, the usage condition second. Every clause carries information and nothing is padded.

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?

An output schema exists, so the return-value sentence is not strictly required, but the description still conveys purpose, trigger condition, and outcome semantics for a simple one-parameter tool. Adequate coverage; nothing essential for correct invocation is missing.

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% and the single 'hash' parameter is fully documented (64-char SHA-256, where it is embedded). The description only restates 'by content hash' and adds no format or sourcing detail beyond the schema, so the baseline 3 applies.

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 specific verb (verify) and resource (a signed PhaseFolio export) plus the mechanism (by content hash). No sibling tool does anything similar, so the agent can distinguish it immediately from get_evidence or get_dossier.

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

Usage Guidelines4/5

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

Gives a concrete triggering situation: 'when a user shares a PhaseFolio asset snapshot and you want to confirm it's authentic before citing the analysis.' This is a clear use context, though it names no alternatives or exclusions (e.g., what to do when no hash is available).

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