Errata Documentation

Errata exposes five read-only tools. Use the workflow-level tool for a concrete engineering task and the atomic tools for discovery or drill-down.

Tool selection

Need	Tool
Find parts across the full official selector catalog	`search_parts`
Inspect official sources and archive state for one selector part	`get_part_sources`
Resolve a concrete or partial identifier to a canonical target	`resolve_part`
Retrieve one bounded topic with hard filters	`get_context`
Review a peripheral across pins, registers, electrical limits, and errata	`get_peripheral_bringup`

`search_parts`

{
  "part_query": "STM32U5A5",
  "candidate_limit": 10
}

Searches device identifiers, exact ordering codes, and publisher ordering-code patterns. The result distinguishes resolved, ambiguous, and not_found. It returns selector metadata and source coverage, but catalog presence does not imply verified engineering facts exist.

`get_part_sources`

{
  "part_number": "STM32H743ZI"
}

Pass an exact part_number returned by search_parts. The response includes official publisher URLs, archived acquisition URLs, revisions, SHA-256 digests, byte counts, acquisition trust, explicit source gaps, and verified-release availability.

`resolve_part`

{
  "part_query": "STM32F407VGT6",
  "query": "USART3 on LQFP100",
  "corpus_release": "89f5e2af40d993eb",
  "candidate_limit": 10
}

Resolution returns canonical MPN, packages, silicon revisions, topics, documents, quality counts, and available corpus releases. A broad identifier returns ranked candidates without silently choosing hardware. query ranks only identifier-matching candidates; it does not override the hardware identity.

`get_context`

{
  "part_query": "STM32F407VGT6",
  "topic": "pins",
  "peripheral": "USART3",
  "package": "LQFP100",
  "query": "TX and RX pins",
  "corpus_release": "89f5e2af40d993eb",
  "limit": 20,
  "max_tokens": 4000
}

Supported topics are registers, pins, electrical, and errata. Package, peripheral, revision, release, limit, and token budget are deterministic constraints. Hardware filters run first; the optional engineering query ranks only the surviving verified facts.

Use page.next_cursor exactly as returned. A cursor is bound to the release, part, topic, query, and filters. Do not construct or reuse it with different arguments.

Status meanings:

Status	Meaning
`ok`	Verified facts matched the hard filters and optional query.
`not_indexed`	No verified fact exists under the hardware filters.
`no_match`	Facts exist under the filters, but none match the engineering query.

`get_peripheral_bringup`

{
  "part_query": "STM32H743ZI",
  "peripheral": "ADC1",
  "package": "LQFP 144 20x20x1.4 mm",
  "silicon_revision": "V",
  "corpus_release": "89f5e2af40d993eb",
  "engineering_goal": "Production schematic and firmware sign-off: verify ADC1 analog input and VREF limits, accuracy, sampling throughput, calibration, BOOST clock, ordering temperature suffix, and initialization sequence.",
  "response_format": "concise"
}

The server resolves the target, exhaustively paginates relevant topic facts internally, selects a task-shaped subset, joins direct and cross-cutting errata, and reports intentional omissions and unsupported details.

Possible decisions are go, conditional_go, blocked, and resolve_target. concise is optimized for an agent’s working context. Use detailed or follow next_actions into get_context for exhaustive evidence.
