## Quality 69/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 10 of 10 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_pricing (destructiveHint, idempotentHint); get_guidance_changes (destructiveHint, idempotentHint); get_verification_evidence (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 764 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 15 tool changes in 30 days
- fail `stability.rug_pull`: 5 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 10, about 764 tokens to load them all
- tool set hash: 2e6e4a2f80b29a096d14de22187ac874
- tools last changed: 2026-10-06T21:57:54.128Z
- badge: [![protogrid quality](https://protogrid.dev/badge/uk.aios-system/public-discovery.svg)](https://protogrid.dev/servers/uk.aios-system/public-discovery)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-06 `get_verification_evidence` changed (description) **meaning changed**
  - before: Return preserved G05 verification evidence and a bounded authoritative-source excerpt. Free.
  - after: Use when an agent needs evidence for a consequential answer: authoritative source identity, verification time, provenance and a bounded excerpt from a monitored GOV.UK employment source. Free.
- 2026-10-06 `get_guidance_changes` changed (description) **meaning changed**
  - before: Return the latest preserved material change evidence for a monitored G05 source. Free.
  - after: Use when the task asks whether monitored official UK employment guidance changed, what changed, or whether earlier retained guidance differs from the latest preserved state. Free.
- 2026-10-06 `check_guidance_status` changed (description) **meaning changed**
  - before: Return current preserved G05 verification status for one or all monitored sources. Free.
  - after: Use before answering or acting when current official GOV.UK employment guidance materially matters. Returns current preserved verification status, freshness and provenance for one or all monitored sources. Free.
- 2026-10-06 `search_guidance_sources` changed (description) **meaning changed**
  - before: Search monitored GOV.UK guidance sources by ID, name or category. Free.
  - after: Use when ordinary employment/payroll language must be mapped to a monitored G05 source before checking current official guidance. Searches only the bounded GOV.UK source set. Free.
- 2026-10-06 `list_guidance_sources` changed (description) **meaning changed**
  - before: List monitored GOV.UK guidance sources using the live G05 evidence service. Free.
  - after: Use when an agent first needs to see which UK employment-guidance classes G05 can verify. Lists only the monitored GOV.UK source set; do not use as legal advice or for unrelated GOV.UK content. Free.
