Get Actor run

get-actor-run

Read-onlyIdempotent

Get detailed information about a specific Actor run.

Instructions

Get detailed information about a specific Actor run.

Returns run result: status, storages (datasets/keyValueStores alias map), stats, summary, nextStep.

summary describes the past (e.g. "SUCCEEDED in 22s. 47 items; 3 fields available.").
nextStep prescribes one primary follow-up action with identifiers interpolated (e.g. "Use get-dataset-items with datasetId=...").
waitSecs (0–45, default 30) waits up to that many seconds for terminal status before returning.

USAGE:

Use to check the status of a run started by any Actor-running tool.
Pass waitSecs > 0 to block until terminal (or until the cap elapses).

USAGE EXAMPLES:

user_input: Show details of run y2h7sK3Wc
user_input: Wait for run y2h7sK3Wc to finish

Input Schema

Name	Required	Description	Default
`runId`	Yes	The ID of the Actor run.
`waitSecs`	No	Maximum seconds to wait for the run to reach a terminal state (SUCCEEDED, FAILED, ABORTED, TIMED-OUT). 0 returns immediately with the current status. Cap: 45. Default: 30.

Output Schema

Name	Required	Description
`tip`	No	Advisory guidance RAG Web Browser wrote to its key-value store under the reserved "TIP" key
`runId`	Yes	Actor run ID
`stats`	No	Run statistics
`status`	Yes	Run status: READY \| RUNNING \| TIMING-OUT \| TIMED-OUT \| ABORTING \| ABORTED \| SUCCEEDED \| FAILED
`actorId`	Yes	Stable Apify Actor ID from the run record
`summary`	Yes	Past-tense summary of the run state
`exitCode`	No	Actor process exit code; populated for terminal states (especially FAILED)
`nextStep`	Yes	One primary follow-up action with identifiers interpolated
`storages`	Yes	Dataset and key-value store metadata, keyed by alias. "default" is always the primary entry.
`actorName`	No	"username/actor-name"
`startedAt`	No	ISO timestamp when the run started
`finishedAt`	No	ISO timestamp when the run finished (terminal states only)
`statusMessage`	No	Pass-through from Apify run.statusMessage
`apifyConsoleUrl`	No	Personalized Apify Console link to the run; present only for Console sessions

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, but the description adds real behavioral context beyond them: the summary vs. nextStep semantics, and that waitSecs blocks for up to 45s (default 30) before returning the current state. This is substantive added value, though it doesn't cover error/failure modes.

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

Conciseness4/5

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

Front-loaded with the core purpose, then segmented into Returns/USAGE/EXAMPLES blocks. Every line carries information, though the two usage examples are somewhat redundant with the USAGE prose, adding minor length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and 100% parameter coverage, the description need only orient the agent, which it does fully: purpose, when to use, wait semantics, and concrete invocation examples. Nothing needed to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description goes further by framing waitSecs as a blocking/wait mechanism with its cap and default, and by describing what runId's run produces. Slight above-baseline value over the schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Get detailed information about a specific Actor run') and enumerates the returned result fields (status, storages, stats, summary, nextStep). It does not explicitly distinguish itself from siblings like call-actor or abort-actor-run, so it falls just short of the 5 benchmark.

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?

The USAGE block names the condition ('check the status of a run started by any Actor-running tool') and explains when to pass waitSecs > 0 to block until terminal. It gives clear context but stops short of explicit exclusions or naming the sibling to use for other run operations.

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