Почему упала сборка

diagnose_deploy

Read-only

Why a deploy failed — with the cause parsed out, not a raw log.

Without `deploy` the latest build is used; that is what reflects the
current state. To examine a specific older one, pass its id.

The response is not a log tail but the neighbourhood of the fatal line:
the platform has already picked out what matters. Read `verdict` and the
summary, fix the code, deploy again — you close this loop yourself,
without involving the person.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`deploy`	No	id конкретной сборки. Без него берётся самая свежая — она и отражает текущее состояние проекта.
`project`	Yes	Проект: слаг (`my-site`) или id. Слаг — то, что видно в адресе сайта; если пользователь назвал сайт словами, возьми слаг из `my_projects`.

A4.5/5.0

Behavior4/5

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

Beyond the readOnlyHint annotation, the description discloses that the response is not a log tail but a pre-parsed 'neighbourhood of the fatal line', and that it contains verdict and summary fields. It also reveals the default behavior of using the latest build. This adds meaningful behavioral context.

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

Conciseness5/5

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

The description is about five short sentences, each earning its place. It front-loads the core purpose, then covers parameter behavior, response nature, and workflow—no filler or redundancy.

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 presence of an output schema, the description doesn't need to detail return fields. It covers the tool's purpose, default behavior, response semantics (verdict/summary), and the self-service workflow. It is sufficiently complete for an agent to select and invoke it correctly.

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%, so the baseline is 3. The description adds extra value by explaining the semantic implication of the deploy parameter: omitting it uses the latest build, which 'reflects the current state'. This clarifies the mental model beyond the schema's 'default: null'.

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 opens with a specific verb and resource: 'Why a deploy failed — with the cause parsed out, not a raw log.' It clearly differentiates from raw-log tools like deploy_logs by emphasizing the parsed cause and the 'neighbourhood of the fatal line', making it distinct among siblings.

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?

It gives explicit context about the deploy parameter: without it the latest build is used, and to analyze an older one you pass its id. It also implicitly excludes raw log use by stating 'not a raw log', though it does not name a specific alternative tool.

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

A3.7/5.0

Disambiguation3/5

Most tools are distinct, but there's real confusion risk between the deploy-related set (cancel_deploy, retry_deploy, deploy_logs, diagnose_deploy) and the site-inspection set (site_status, read_site, site_issues, site_screenshot) where purposes overlap. compose_landing vs compose_landing_submit are differentiated mostly by an obscure note rather than naming. Several tools address similar concepts (landing composition, publishing, deploy) making agent misselection plausible.

Naming Consistency3/5

Most tools use a clean verb_noun pattern (list_deploys, connect_domain, check_domain, publish_landing, read_site, rollback). However, conventions are mixed: some use compose/x/check/y (check_copy, check_domain, check_performance) while others use site_x (site_status, site_analytics, site_issues, site_screenshot) with inconsistent ordering. Descriptions mix English and Russian heavily, though that's content not naming.

Tool Count4/5

27 tools is a large but arguably justified surface for a full site-building/deploying/monitoring platform spanning composition, domain management, deploys, performance, analytics, and environment configuration. It sits slightly above what feels tight, but each tool has a defined role in the overall workflow.

Completeness4/5

The surface covers the full landing lifecycle: compose, publish, deploy, monitor, rollback, diagnose, and connect external resources (domain, analytics, integrations). Minor gaps: no explicit tool for site deletion/teardown, only read_site for editing with refactor_site being narrow, and no way to update an existing landing's text beyond refactor. Still, core CRUD and operational flows are covered.
