```


## Deletes or cancels (7)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_deploy`

- The name "cancel_deploy" says "cancel": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Stop a build that is still running.

    The live address does not change — the previous version stays on it.
    
```

### `data_api_grant`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Who may call a method of a table or a function: shows the SQL and
    applies it after consent.

    OPENS DATA TO THE INTERNET. Call it without `apply` first: the platform
    returns the commands and warnings (for example "row-level security is
    off — a visitor will get every row"). Show them to the person. With
    apply=true a client with forms asks the person itself; without forms get
    consent in the chat and pass confirmed=true together with expected_sql
    from the preview.

    Methods you do not name keep their current level. Exactly the shown
    commands are applied: if the grants changed meanwhile, the platform
    refuses — show the new ones. Needs a token with the admin scope, for the
    preview too.
    
```

### `data_api_keys`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
The database's Data API keys: list, issue, revoke.

    The list never contains key values. Issuing and revoking need the
    person's consent: a client with forms asks by itself; without forms ask
    in the chat and pass confirmed=true. The value of an issued key is
    returned once: the platform does not store secret keys. Hand it to the
    person for their server and do not repeat it afterwards.

    Revoking breaks everyone who uses the key — including the site, if the
    key is baked into its build (`in_build`). Issuing and revoking need a
    token with the admin scope.
    
```

### `data_api_origins`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Sites allowed to call the database from a browser: list, add, remove.

    Addresses of the connected projects and their branches are allowed
    automatically — do not add them. An added site opens no data by itself:
    what can be read and written is decided by access levels. Adding and
    removing need the person's consent; a removed site is refused on every
    request. Needs a token with the admin scope.
    
```

### `env_vars`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Project environment variables: list names, set them, remove them.

    VALUES ARE NEVER READ BACK — not by you, not by the platform in its
    response. Only names and lengths are returned. This is a deliberate rule
    rather than an implementation limit: anything that reaches your answer
    settles into the conversation history, and a secret that lands there
    cannot be taken back. If the user asks "what is my key", say plainly
    that you cannot show it and offer to set a new one.

    `set` does not require knowing the other variables — the platform keeps
    them. `unset` removes only the named ones.

    A change needs a new deploy: variables are picked up at build time, not
    on the fly. Say so, or the user will think nothing happened.
    
```

### `project_settings`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Build settings of a project: read them, or change them without the
    dashboard — the way out when detection guessed wrong (wrong folder,
    wrong type, wrong command).

    `get` returns `settings` (what is saved on the project; null — not set,
    the platform decides), `resolved` (what the next build will actually use,
    per field: `value`, `source`, `policy`) and `last_build` (what the latest
    ready build was really built with). Precedence is `layero.json` in the
    repository > project settings > detection > framework default: a field
    with `policy: "locked_by_file"` is set by `layero.json`, and changing the
    project setting will not change the build — edit the file instead.

    `update` CHANGES HOW THE PROJECT IS BUILT — ask the person first unless
    they asked for exactly this change. Prefer `layero.json` in the repository
    for anything that should live with the code; use this tool for what the
    file cannot hold (`root_directory`, `project_type`) and for projects you
    cannot push to. Nothing is rebuilt by the update itself: apply it with
    `retry_deploy(redeploy=true)` or a push.
    
```

### `rollback`

- The description's first verb is "put": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Put the previous working build back on the live address.

    CHANGES WHAT VISITORS SEE — ask the person before calling unless they
    asked for a rollback explicitly. The action is reversible (you can roll
    forward again), but the time visitors spent on the wrong version cannot
    be taken back.

    ⚠[U+FE0F] For apps (`ssr_next`, `node_web`, `python_web`, `streamlit`, `gradio`,
    `flask`) a rollback works differently from static sites and is often
    impossible: an app has no ready artifact to simply switch to. If the
    platform refuses, explain that to the person plainly and suggest
    rebuilding the earlier commit — do not repeat the call.
    
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `publish_landing`

- The name "publish_landing" says "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
DEPRECATED — use `publish_site`. Same behaviour, same arguments.

    Kept for one release (removed in the next) so that configs and prompts
    written before 17.09.2026 keep working; new instructions must call
    `publish_site`.
    
```

### `publish_site`

- The name "publish_site" says "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish a static site to Layero — from here, with no terminal.

    Takes ANY ready static bundle, so it is the answer to "deploy my site" when
    the project has no connected repository. Requirements — `index.html` at
    the root, at most 200 files, 8 MB in total, 2 MB per file. Binary files
    (images, fonts) must come with `encoding="base64"`; sent as text they are
    silently corrupted.

    Do NOT use it for a project with a connected repository (`site_status`
    shows one): the next git push would overwrite what you published.

    Publishing without a Layero account is not possible from here — the
    server requires sign-in. For that case there is the CLI:
    `npx layero@latest deploy --claim` deploys first and lets the person
    claim the site later. An empty project for a future publish is created
    with `project_create`.

    A project that still needs a build step (Vite, Next, Astro — anything
    where the answer is `npm run build`) does NOT go here: publish its build
    output, or tell the user to run `npx layero@latest deploy`, which builds
    on our side.

    Send the ACTUAL file contents: the server does not remember the bundle
    between calls. If the user edited the text after generation, pass the
    current versions, or what gets published is what used to be there.

    Pass `project` (the id of an existing project) when republishing the
    same site; without it the platform finds a project with that name or
    creates a new one.

    Returns as soon as the build finishes, or after ~40s with `status`
    `building` and the `deploy_id` — the build keeps going on its own. Never
    call this tool a second time to "retry" a build that is still running:
    that starts a SECOND build. Follow `next_action`.
    
```

## Changes things (17)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_copy`

- The name "check_copy" says "copy": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Mechanical errors of Russian typography — with the exact place and a
    replacement.

    This is CODE, not a model's judgement: the same text gives the same list
    of findings. It catches what the eye misses and the reader feels:
    non-breaking spaces, dashes, straight quotes, a dot instead of a comma in
    decimals, spaces around punctuation, double spaces.

    Every finding carries a ready replacement — apply it rather than
    rewriting the fragment your own way.

    WHAT IS NOT HERE. Plain style, sentence length, officialese, signs of AI
    slop — that is judgement, and it lives in the `layero://editorial/ru`
    resource. Read it when asked to "make the text better" rather than "fix
    the typography".
    
```

### `check_domain`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check whether a connected domain has started working.

    Runs the DNS check immediately instead of waiting for the background
    re-check. If the records have not propagated yet, that is normal — say
    so and suggest coming back later.
    
```

### `check_performance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Measure a site's speed and say whether it got worse after a deploy.

    The verdict comes FROM THE SCORE, not from timings: repeated runs of the
    same deploy vary by at most one point, while LCP and TTFB on identical
    code swing by 37-40%. A difference of 3 points or more is meaningful;
    anything smaller is measurement noise, and calling that a regression is
    inventing a problem.

    A run takes tens of seconds. With `wait=true` the tool waits for you; do
    not start a second measurement in parallel — it will occupy the queue
    and add nothing.
    
```

### `check_rules`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check the published site against Layero's anti-phishing rules
    (https://layero.ru/rules): collecting passwords, card details or wallet
    recovery phrases of another service, fake security warnings, vote and
    prize lures that send visitors to another domain.

    Checks what a visitor sees at the project address — the home page and its
    own scripts. `violations` is empty when nothing matches. `publish_site`
    and `site_status` run the same check after a deploy and add
    `rules_warnings` only when something matches, so a separate call is needed
    only when the user asks.
    
```

### `connect_analytics`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Connect Yandex Metrika to a site.

    IMPORTANT: authorisation happens IN A BROWSER, and neither you nor the
    platform can do that step for the user. The tool returns a link — show
    it and ask them to open it and grant access. Do not poll in a loop: the
    person may walk away for an hour. Check later through this same tool
    without the `branch` argument, or through `site_analytics`.
    
```

### `connect_domain`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Connect a custom domain to a site.

    IMPORTANT: between this call and a working domain stands A PERSON. You
    get DNS records — show them to the user and explain they go in at their
    domain registrar. Do not wait for readiness: DNS propagates in minutes
    to an hour, the platform re-checks on its own, and you check later via
    `check_domain`. Spinning here burns time and context for nothing.

    The address can be passed as-is: the platform reduces
    `https://shop.example.com/page` to `shop.example.com` itself.
    
```

### `data_api_methods`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The database's REST and RPC methods with an access level per HTTP method.

    The level says who may call the method: closed, visitor (any site
    visitor), user (signed-in people), server (the server only). It is read
    from the role grants in force in the database itself — exactly as the
    gateway sees them.
    
```

### `data_api_probe`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
A real request to a method through the gateway — as a visitor, a user
    or the server.

    The platform supplies the key and the token. Writes (POST, PATCH, DELETE,
    a function call) are rolled back: rows in the database do not change,
    but the rollback does not undo sequence numbers, calls from the database
    to the outside, session locks or the daily call quota. The answer is
    real: grants, row policies and refusals are the same the site will see.
    Needs a token with the admin scope.
    
```

### `deploy_logs`

- The name "deploy_logs" says "deploy": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Raw log lines — for when the `diagnose_deploy` analysis was not enough.

    Start with `diagnose_deploy`: it has already pulled out the cause and
    the neighbourhood of the fatal line. Come here when you need to look
    with your own eyes — the cause is vague, or you are interested in how
    the app behaves rather than in a failure.

    You get the TAIL. `truncated` says earlier lines were dropped; do not
    present the tail as the whole log. For build logs, package-manager
    network chatter is hidden BEFORE the tail is cut, so the tail holds
    meaningful lines; `noise_hidden` says how many were hidden and
    `include_noise=true` shows them.
    
```

### `diagnose_deploy`

- The name "diagnose_deploy" says "deploy": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info long-description, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.

    `build_facts` — how it was built: `project_type`, `framework`,
    `node_version`, `package_manager`, `install`, `build`, `output` (each
    with its origin in parentheses: default, auto-detected, layero.json,
    dashboard …), `source` (`git` / `cli`), `root_directory`, `queued_s`,
    `duration_s`. Apps built into a container (`node_web`, `python_web`,
    `ssr_next`, full-stack) also get `runtime_kind`, `start` (the start
    command), `port`, `env` and, for full-stack, `fullstack` /
    `fullstack_frontend`. A value marked `(as built)` is the platform's
    record of this very build; `(current settings: …)` is what the project
    settings resolve to now, not a fact about this build. A missing key
    means the platform did not report that fact — on a failed build often
    because it did not get that far, on a `ready` build it just is not
    recorded (static builds print more than container builds); it is not a
    sign of a problem. `sources_note` appears when a value is marked
    `(from dashboard)` / `(from hint)`: that is «saved in the project
    settings», by a person or by import-time detection — the platform does
    not record which. `candidate_app_dirs` is filled when the builder found
    several app folders in a monorepo and needs a `root_directory`.

    Three log excerpts, all untrusted: `build_log_excerpt` — the build
    itself; `launch_log_excerpt` — the platform's lines about starting the
    app after the build (container launch, readiness probe, wake-ups), empty
    for static sites; `runtime_log_excerpt` — what the app printed.

    `next_action` is the instruction for you. `next_actions` is a separate,
    machine-readable list of platform codes, possibly empty: `wait`,
    `poll_status`, `fix_config`, `fix_code`, `fix_runtime`, `check_env`,
    `inspect_logs`, `retry_deploy`, `runtime_idle` (the app is scaled to
    zero — normal, it wakes on the next request).
    
```

### `import_repo`

- The name "import_repo" says "import": a word for a change.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Create a Layero project from a repository — path (a) without the
    dashboard. From then on a push to the branch is a preview, a push to the
    production branch is production.

    After the link the tool finishes the setup wizard itself and starts the
    first build; `setup` in the result says whether that happened. Detected
    values are NOT written into the project settings: the builder detects
    the framework, build command and output folder from the repository on
    every build, so a later change in the repository is picked up. Only a
    decision is pinned — the app folder of a monorepo and the package
    manager named in `layero.json`. Until 2.1.1 the project stayed in
    `pending_setup` while the answer promised a build that never started.

    Two shapes, same as the CLI: GitHub goes through the App installation
    (project and webhook in one call); other providers create the project
    first and then connect the source — that step reports whether the
    webhook could be registered. If the provider is not connected, the result
    says `needs_connection` with the dashboard address: the person connects
    the token there, never through the chat.

    Monorepo: one project builds one app folder — pass `root_directory`.
    Several apps in one repository are several projects, one call each, with
    different `root_directory` and `name`. If the repository is already
    linked and the call would duplicate an existing project (same folder, or
    no `root_directory` given), nothing is created: the result is
    `already_linked` with `linked_projects` — slug, url, root_directory and
    branch of every project built from this repository. On `created`,
    `linked_projects` lists the OTHER projects already built from the same
    repository; `linked_projects_checked: true` says the check was made, so
    an empty list means there are none (`my_projects(repo=…)` answers the
    same question later). When the root has no
    app and detection sees a frontend + backend pair, `app_dir_candidates`
    names the folders.
    
```

### `my_projects`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The user's sites on Layero.

    Thirty most recent by default. The full list is rarely needed, while
    flooding half your context with it is easy: an active user has dozens
    of projects.

    `url` is the canonical (production) address. `repo`, `branch` and
    `root_directory` say where the project is built from: all three are
    null for a project without a repository (CLI or `publish_site`);
    `root_directory` is the app folder inside a monorepo, null for the
    repository root.
    
```

### `project_create`

- The name "project_create" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an empty project with no repository — an address reserved for a
    later `publish_site` or `npx layero@latest deploy`.

    For a project FROM a repository use `import_repo` instead. Nothing is
    built or served yet: the address answers only after the first publish.
    
```

### `refactor_site`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
One named markup transformation — with a predictable result.

    The tool PUBLISHES NOTHING. It returns the changed HTML; showing it to
    the person, getting consent and calling `publish_site` is your job.
    Never rewrite someone's site silently.

    Transformations are idempotent: a repeated call changes nothing and
    honestly answers `changed=false`. An empty list of changes is not an
    error, it means "there was nothing to apply".

    ⚠[U+FE0F] WHAT IS NOT HERE AND WHY. Fonts from third-party hosts, re-encoding
    images to webp and untangling inline styles are NOT included: they need
    the files themselves, which the server does not have, or a judgement
    about the intended look. `site_issues` names those problems — with a
    location and an explanation; whoever holds the files fixes them.

    The gain is measured with `check_performance` BEFORE and AFTER the
    publish. A difference under three points is measurement noise, not an
    improvement — say so.
    
```

### `retry_deploy`

- The name "retry_deploy" says "deploy": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run a build again — a failed one as is, or the latest commit afresh.

    Default (`redeploy=false`): queue the SAME build again. Allowed only for
    builds in the `failed` or `cancelled` state. On a running build
    (`queued`, `building`) the platform refuses — that is not an error but
    protection against a second parallel build; on a `ready` build it
    refuses too — use `redeploy=true`.

    `redeploy=true`: start a NEW build of the branch's latest commit without
    a push. This is how changed project settings (`project_settings`) or
    environment variables (`env_vars`) get applied. The result goes live the
    same way a push to that branch would — on the production branch that is
    production, so make sure the person wants that. Projects without a
    repository are rebuilt by deploying the folder again
    (`npx layero@latest deploy` or `publish_site`).

    ⚠[U+FE0F] A plain retry makes sense when the cause was external (network,
    registry, timeout). If the build failed on the code, a retry gives the
    same result: `diagnose_deploy` first, then the fix, and only then a retry.
    
```

### `site_analytics`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Site traffic: totals, direction and top sources.

    The time series is collapsed into a direction and breakdowns are cut to
    five: ninety chart points are useless in your context, and the
    conclusion is yours to draw anyway.
    
```

### `site_issues`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Concrete problems of a page — each with its location and what to do.

    This is NOT a score. The score comes from `check_performance`, and a
    score gives nothing to fix: "73 out of 100" does not say what to change.
    Here is only what has a location and a clear action: blocked indexing,
    resources from foreign hosts, raster images without webp, missing meta
    and alt, forms with no recipient.

    Findings are sorted by importance. Do not dump the list — name the two
    or three main ones and ask whether to fix them.
    
```

## Only reads (10)

Looks things up and changes nothing. Claude Code: allow.

### `data_api_status`

- The name "data_api_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Whether the database has the Data API enabled, its address, keys and
    the sites allowed to call it.

    Keys are shown as prefixes only: the platform never returns values and
    does not store secret ones. The API cannot be enabled with a tool:
    enabling gives the database a public address, and that is the person's
    decision in the dashboard.
    
```

### `list_deploys`

- The name "list_deploys" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The project's latest builds: how each one ended, how long it took and
    which one is live now.

    Use it to pick a target for `rollback` or `diagnose_deploy`. For "what is
    up with the site right now" `site_status` is enough and cheaper.

    Per build: `branch`, `source` (`git` — built on push, `cli` — an uploaded
    folder), short `commit`, `created_at` / `started_at` / `finished_at`
    (UTC), `queued_s` (wait in the queue) and `duration_s` (build time, null
    while it is still running), `failure_stage` for failed ones, `is_active`
    — the build now served on the canonical address.
    
```

### `list_domains`

- The name "list_domains" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The project's own domains and their state.
```

### `list_environments`

- The name "list_environments" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The project's environments — one per branch (or the single `cli` one),
    each with its address and the state of its latest build.

    Answers "where is the preview of my branch" and "what is on production
    now". `url` is the environment's own address (its host ends with
    `-<branch>`); the production branch is ALSO served at the project's
    canonical address from `site_status` / `my_projects`. Take addresses
    from here, never assemble them.
    
```

### `list_sources`

- The name "list_sources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which git providers Layero supports and which of them the organization
    has connected (GitHub App installations and provider tokens).

    Call before `import_repo` when you are not sure the provider is
    connected. Connecting a provider token is done by the person in the
    dashboard — never ask them to paste the token into the chat.
    
```

### `read_site`

- The name "read_site" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What is really published: headings, copy, forms, meta, links.

    Call it BEFORE changing anything on a live site and AFTER a publish, to
    make sure the expected version arrived. Without it you edit blind: what
    lies on the user's disk and what visitors are served are different
    things, and they drift apart silently.

    The result is a STRUCTURE, not raw HTML: a page with inline styles would
    eat half your context, while what you need from it is headings, copy,
    forms and meta. The full source is on the user's disk.

    `served_fallback=true` means this path was answered with the home page:
    there is no page at this address, and the storage answered the missing
    key with its `index.html` and a 200. Do not take that for success.
    
```

### `search_docs`

- The name "search_docs" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search docs.layero.ru — no token needed.

    Use it before guessing how the platform works: build settings and
    `layero.json`, environments and preview URLs, custom domains, env vars,
    runtime apps, Data API, CLI flags and JSON events. Returns the page
    title, a direct URL (with anchor) and a snippet; open the URL with your
    own fetch tool when the snippet is not enough. `score` is relative
    within one answer: a rare query word found in a page title weighs most,
    and a page matching every word ranks above one repeating a single word.

    The index is the site's own search index, refreshed hourly.
    
```

### `site_screenshot`

- The name "site_screenshot" says "screenshot": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A screenshot of the latest built version of the site — how it looks.

    Complements `read_site` (what is on the page) and `site_issues` (what is
    wrong with it) with the third question: how it looks. Useful before and
    after a visual change.

    ⚠[U+FE0F] The screenshot is taken at BUILD time, not now. Right after a publish
    a fresh one does not appear instantly — do not present the previous one
    as the result of your change.

    An image costs far more context than text. Do not call it "just in
    case": for "what is wrong with the site" `site_issues` is cheaper and
    more specific.
    
```

### `site_status`

- The name "site_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How a site is doing: where it is built from, whether the address is
    answering, and how the latest build ended.

    One call instead of three (project, deploys, live check of the address).
    `source` / `repo` / `branch` / `root_directory` say where the project is
    built from — a connected repository means deploys go through git.

    `serving` is true when the SITE ITSELF answered — any response that is
    not a Layero platform screen and not a 5xx. An API server that has no
    `/` route answers with its own 404: that is a running app, not a broken
    site — check a real route with `path`. `answered_by` tells who replied:
    `site`, `platform` (a Layero screen, named in `platform_screen`:
    `unavailable`, `coming-soon`, `starting`, `not-found`, `suspended`) or
    `none` (no response). Redirects are not followed: `redirect_to` shows
    the target.

    Waiting for a build: while the latest build is running the answer carries
    `poll_after_s` — call again after that many seconds. Or pass `wait_s` and
    the server waits for the build itself (mind your client's tool-call
    timeout, see the argument). `waited_s` says how long the call waited.

    Static sites: `served_fallback: true` means the requested `path` was
    answered with the HOME page (a missing file is replaced by `index.html`
    with code 200) — the address answers, but this page does not exist.
    
```

### `whoami`

- The name "whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Who is connected to Layero and how many projects they have.

    Call this first when you are unsure the token is configured: a clear
    error here is cheaper than one halfway through a deploy.
    
```
