• aws___get_presigned_urloutputSchema declared

  Generate pre-signed S3 URLs for uploading or downloading files. Use BEFORE run_script when an operation requires a local file. Use for direct S3 uploads/downloads. Max upload 5 GB; larger files use multipart. For uploads: generates PUT URL. For downloads: generates GET URL. No special headers needed unless s3_params provided—then corresponding HTTP headers MUST be included or request fails with SignatureDoesNotMatch.

  Input requests: array

  • requests: arrayrequired

    Array of 1-25 presigned URL requests.

• aws___get_regional_availabilityNo outputSchema

  AWS resource availability per region. - Max 10 regions; multi-region needs `filters`; single-region supports `next_token`. - Status: isAvailableIn | isNotAvailableIn | isPlannedIn | Not Found. - Response key: products | service_apis | cfn_resources. Not for region counts/docs/vague queries -- use `search_documentation` / `list_regions`. Filter values must EXACTLY match AWS's catalog names; guessed, partial, or pluralized names are rejected ("values in filter parameter do not exist"). If unsure of the exact name, first call once for a single region with resource_type set and NO filters to list

  Input filters?: array, next_token?: string, region?: string, regions?: array, resource_type: string

  • filters?: arrayoptional

    Use exact AWS product or sub-feature name. - product: 'Amazon Bedrock' (service), or sub-features like 'Comprehend Auto Scaling', 'Latency-Based Routing', 'PrivateLink Support'. When the user names a specific sub-feature, filter on the sub-feature -- do NOT generalize to the parent service ('Amazon Comprehend'); that returns availability for the wrong scope. - api: 'SdkServiceId+Operation' (e.g. 'CloudFormation+CreateStack', 'IAM+GetSSHPublicKey') or 'SdkServiceId' (e.g. 'EC2'). Use a literal '+' between service and operation -- not space, colon, or hyphen. - cfn: 'AWS::EC2::Instance', 'AWS::L

  • next_token?: stringoptional

    Pagination token. Single-region, no filters only.

  • region?: stringoptional

    Unused; use `regions`.

  • regions?: arrayoptional

    AWS region codes (max 10). Multi-region requires `filters`; single-region supports `next_token`.

  • resource_type: stringrequired

    Required: 'product' | 'api' | 'cfn'.

• aws___get_tasksoutputSchema declared

  Poll status of long-running tasks. Use after a tool call returns task_id with status "working". Up to 3 IDs per call. Tasks expire after 5 min. Pass poll_iteration (start at 1, increment each call) and follow the recommended_wait_seconds in the response before polling again.

  Input poll_iteration?: any, task_ids: array

  • poll_iteration?: anyoptional
  • task_ids: arrayrequired

    One or more task IDs (up to 3) from previous tool invocations.

• aws___list_regionsNo outputSchema

  Retrieve a list of all AWS regions.

  Input No parameters

• aws___read_documentationNo outputSchema

  Fetch full AWS doc pages as markdown. `search_documentation` already returns verbatim page chunks, so don't re-read a URL whose chunk you already have to "confirm" or "round out" an answer -- the chunk is the real page text; treat it as authoritative. Reading the full page is justified ONLY when the chunks genuinely lack the content: - an enumeration or aggregation ("list all X", "how many X") needs the complete set and the chunks show only part of it; - no search result is on-topic after refining the query, and a known doc URL would have the answer. Otherwise, answer from the chunks. Use exac

  Input requests?: array

  • requests?: arrayoptional

    List of `{url, max_length?, start_index?}`. Batch 2-5.

• aws___retrieve_skillNo outputSchema

  Retrieve an AWS skill (workflows, references). Returns SKILL.md, or `file` if given. Call `search_documentation` FIRST and copy `skill_name` verbatim -- it is an opaque registry ID. Never guess or fabricate `skill_name` or `file`.

  Input file?: string, skill_name: string

  • file?: stringoptional

    Optional file path within the skill, copied as cited (e.g. `references/architecture.md`). Don't add or strip a `references/` prefix. Omit for SKILL.md.

  • skill_name: stringrequired

    Required. Exact `skill_name` from a search_documentation result, copied verbatim. Do not invent or modify.

• aws___run_scriptNo outputSchema

  Execute Python code in sandboxed environment with AWS API access via `call_boto3`. No network except `call_boto3`. ```python async def call_boto3( *, service_name: str, operation_name: str, region_name: str | None = None, params: dict | None = None, ) -> dict: ... ``` ``operation_name`` MUST be the PascalCase AWS API operation name (e.g. ``ListBuckets``, ``GetTable``, ``StartQueryExecution``). Do not use the snake_case boto3 method name (``list_buckets``, ``get_table``); exact matches are corrected only as a runtime fallback. Response includes `api_calls` list—verify APIs ran before trusting `

  Input code: string

  • code: stringrequired

    Python code to execute

• aws___search_documentationNo outputSchema

  AWS docs search. Each result's `context` is verbatim page text -- a real chunk of the actual page, not a short snippet -- and usually already contains the answer, so answer directly from it. Use `read_documentation` only when the chunks genuinely lack the needed detail. Pick ONE topic. Add a 2nd ONLY if query genuinely spans domains. Extra topics dilute ranking. - reference_documentation -- API/SDK/CLI specs, config params - current_awareness -- new/released/announced - troubleshooting -- errors, "how to fix" (NOT for conceptual/feature questions) - amplify_docs -- Amplify (+ language) - cdk_d

  Input limit?: integer, search_phrase: string, topics?: array

  • limit?: integeroptional

    Maximum number of results to return (default 4).

  • search_phrase: stringrequired

    Keywords; preserve exact error strings and all task terms verbatim.

  • topics?: arrayoptional

    Up to 3 from: reference_documentation, current_awareness, troubleshooting, amplify_docs, cdk_docs, cdk_constructs, cloudformation, agent_skills, strands_docs, general. Default ["general"].
