errors_list

Retrieve grouped error memory for a project with a computed promote-or-revert verdict. Filter by release, function, or error kind to inspect errors after a deployment.

Instructions

Grouped, release-baselined error memory for a project, verdict-first: every page leads with a computed promote-vs-revert verdict (the gateway's numbers — never recomputed here), then the collapsed error identities. The post-promote watch: right after an apply/promote activates a release, call errors_list with new_in set to the just-activated release id (the promote response's next_actions carries a ready-made watch_errors command for the CLI equivalent). verdict.new_fingerprints > 0 means the release introduced NEW error identities — inspect errors[] (each row has samples with request ids + a runnable logs command) and consider reverting; new_fingerprints === 0 with healthy verdict.invocations_in_window means clean under real traffic (0 errors over 0 invocations is absence of signal, not proven health). Filter by since/until/function/kind/fingerprint; pass fingerprint_id to fetch one fingerprint's full detail (all samples + also_seen_in_functions). Quality tier coarse = the function predates the error side-channel; redeploy to upgrade fidelity. Read-only, own-project service-key auth; cursors are opaque.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
kindNoRestrict to one choke-point class: uncaught | boot_crash | invoke_failed | handled_5xx.
limitNoPage size (default 50, max 200).
sinceNoISO-8601 window start. Default window is the last 24h (gateway resolves `until` − 24h).
untilNoISO-8601 window end. Defaults to now (gateway-side).
cursorNoOpaque `next_cursor` from a prior page. Returns the next page. Never parse cursors.
new_inNoA release id, or the literal "active" (gateway resolves the live release). Selects error identities FIRST seen under that release and drives the verdict's new_fingerprints / baseline — the promote-gate signal.
functionNoRestrict to one function by name.
project_idYesProject whose errors to read. Authorized with the project's OWN service key; a key for a different project gets 403, never a 404.
fingerprintNoRestrict the list to one exact fingerprint identity (`fp_…`).
fingerprint_idNoFetch ONE fingerprint's full detail (all samples, per-sample fetch_logs commands, also_seen_in_functions) instead of a page. When set, all filter params (since/until/function/kind/fingerprint/new_in/limit/cursor) are rejected.
Behavior5/5

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

With no annotations, the description fully carries the transparency burden. It discloses read-only nature, auth requirements ('own-project service-key auth'), cursor opacity, quality tier implications, and behavioral traits like verdict computation and promote-watch semantics. No contradictions.

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?

The description is lengthy but well-structured, front-loading the core purpose and verdict-first approach. Every sentence provides valuable context, though it could be slightly more concise by grouping related behaviors. The length is justified by the tool's complexity.

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?

Given the lack of output schema, the description thoroughly explains return values (verdict, errors, fingerprints, samples, fetch_logs commands), pagination, filtering, and edge cases (e.g., '0 errors over 0 invocations is absence of signal'). Covers error codes and auth. Complete for a tool with 10 parameters.

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 description coverage is 100%, but the description adds significant contextual meaning beyond schema fields. For example, it explains the promote-watch use case for 'new_in', details about 'fingerprint_id' fetching full detail, and implications of 'kind' enums. This raises the score above baseline 3.

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

Purpose5/5

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

The description clearly states the tool's purpose: 'Grouped, release-baselined error memory for a project, verdict-first...' It specifies the resource (errors), action (list), and unique approach (verdict-first with promote vs revert). It distinguishes from sibling tools like get_function_logs by focusing on error identities and verdicts.

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 description provides explicit usage guidance, e.g., 'right after an apply/promote activates a release, call errors_list with new_in...' and explains when to inspect new fingerprints. However, it does not explicitly state when not to use this tool or mention alternatives beyond the implicit contrast with other tools.

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