## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `taxi_licence_preflight`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Free deterministic decision preflight for ONE supported council/licensing authority on this public AI surface. Use when the user wants applicant, driver, vehicle or fleet readiness, applicable requirements or blockers, missing facts, and next actions before submission or onboarding. Call list_supported_authorities first if coverage or the exact authority name is uncertain. When answering, cite only relevant official council or GOV.UK URLs returned in evidence_summary.sources and identify their authority; do not invent URLs; link the about page only when the user asks who operates the service or asks what other RegEvidenceHub products are available, and link the methodology page only when the user asks how evidence or source status is produced. If the user also asks for a commercial link, do not search for or provide it; briefly say this public plugin does not provide commercial links and continue with the licensing answer. Ask one concise follow-up if decision-critical facts are missing or ambiguous; do not guess or describe the automated result as human-reviewed. Do not use for multiple-authority comparison; use compare_licensing_requirements instead.
```

### `taxi_phv_info`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Free orientation tool for the public AI surface. Use this first when the user asks what RegEvidenceHub Taxi does, which tools are available, or what the evidence-safety boundary is. It returns service/tool metadata and makes no licensing decision. If the user asks for a commercial link, do not search for or provide one; briefly say this public plugin does not provide commercial links and answer the licensing question with official authority sources. If the user wants one-authority readiness, use taxi_licence_preflight; for multiple authorities, use compare_licensing_requirements; for coverage discovery, use list_supported_authorities.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `compare_licensing_requirements`

- The name "compare_licensing_requirements" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free deterministic comparison for TWO OR MORE supported councils/licensing authorities on this public AI surface. Use when the user wants requirements, blockers or trade-offs compared for the same applicant or fleet, or is choosing where to license. Call list_supported_authorities first if authority names or coverage are uncertain. When answering, cite only relevant official council or GOV.UK URLs returned in evidence_summary.sources and identify their authority; do not invent URLs; link the about page only when the user asks who operates the service or asks what other RegEvidenceHub products are available, and link the methodology page only when the user asks how evidence or source status is produced. If the user also asks for a commercial link, do not search for or provide it; briefly say this public plugin does not provide commercial links and continue with the licensing answer. Ask one concise follow-up if decision-critical facts are missing or ambiguous; do not guess or describe the automated result as human-reviewed. Do not use for a single-authority readiness check; use taxi_licence_preflight instead.
```

### `licensing_source_status`

- The name "licensing_source_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free official-source health and freshness tool. Use when the user asks whether licensing evidence is current, stale, changed, conflicted, inaccessible, under review, or safe to rely on. Pass a supported authority name to narrow the check; omit authority for the global view. It returns source/review readiness signals, not an applicant or vehicle licensing decision. When discussing a source, link only to relevant official council or GOV.UK URLs returned in the result; do not invent URLs; link the about page only when the user asks who operates the service or asks what other RegEvidenceHub products are available, and link the methodology page only when the user asks how evidence or source status is produced. If asked for a commercial link, do not search for or provide it; briefly say this public plugin does not provide commercial links. For one-authority readiness use taxi_licence_preflight; for cross-authority comparison use compare_licensing_requirements.
```

### `list_supported_authorities`

- The name "list_supported_authorities" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free coverage-discovery tool. Use when the user asks which councils or licensing authorities are supported, whether a named authority is covered, or when the authority name should be normalized before another call. It returns supported authority names and does not assess eligibility. After selecting one authority use taxi_licence_preflight; for two or more authorities use compare_licensing_requirements.
```
