## Changes things (4)

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

### `revit_clash_detect`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Perform a lightweight clash analysis between two Revit categories (e.g. Mechanical Equipment vs Structural Framing) using bounding-box overlap where available, falling back to shared-Level proximity, then annotate with any matching VDC rules stored in the D1 database.
When NOT to use: Do not use as a substitute for Navisworks Manage for contractual clash reports — this is a first-pass coordination sniff test, not a certified Clash Detective run.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — verify model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only against APS. May read from D1 vdc_rules table if present. Idempotent.
```

### `revit_export_ifc`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Kick off a Model Derivative translation of a previously uploaded Revit URN into IFC (IFC2x3 Coordination View 2.0 by default) so the model can be exchanged with non-Autodesk tools (Solibri, BIMcollab, Tekla, openBIM workflows).
When NOT to use: Do not use for SVF/SVF2 web viewing (that happens automatically in revit_upload), and do not call repeatedly while a prior IFC job is still inprogress — poll the manifest instead.
APS scopes: data:read data:write viewables:read (Model Derivative job + manifest).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add data:write. 404 URN not found — confirm model_id was translated. 409 not applicable. 429 rate limited — back off. 5xx APS upstream — retry with jitter up to 3x.
Side effects: Creates a Model Derivative job and, on completion, a new IFC derivative inside the model's manifest. Safe to re-run (APS deduplicates) but each call with x-ads-force may retranslate.
```

### `revit_run_schedule`

- The name "revit_run_schedule" says "run": a word for a change.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Build a tabular, spreadsheet-style schedule (rows = elements matching a keyword, columns = up to 15 shared parameters) from a translated Revit model — useful for Door Schedules, Wall Schedules, Room Schedules, and QA/QC exports.
When NOT to use: Do not use when you only need raw element metadata (use revit_get_elements) or parameter schema (use revit_get_parameters).
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
```

### `revit_upload`

- The name "revit_upload" says "upload": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
When to use: Ingest a Revit (.rvt / .rfa / .rte / .rft) file into Autodesk Platform Services by downloading it from a publicly reachable URL, uploading it to an OSS bucket, and starting an SVF2 translation so downstream revit_* tools can read elements, parameters, sheets, and views.
When NOT to use: Do not call if you already have a translated URN (use the existing model_id instead), if the file is not a Revit source file, or if the URL requires authentication the worker cannot satisfy.
APS scopes: data:read data:write data:create bucket:read bucket:create viewables:read (OSS bucket create + object PUT + Model Derivative job).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh credentials and retry. 403 scope insufficient — request data:write + bucket:create. 404 bucket/object not found — confirm bucket was created. 409 bucket exists — safe to ignore, reuse it. 429 rate limited — back off with exponential delay. 5xx APS upstream — retry with jitter up to 3x, then surface.
Side effects: Creates a new transient OSS bucket named scanbim-revit-<timestamp>, uploads the object, and starts a Model Derivative translation job. NOT idempotent — each call creates a fresh bucket and new URN.
```

## Only reads (4)

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

### `revit_get_elements`

- The name "revit_get_elements" says "get": a word for reading.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: After a Revit model has finished translating, fetch the first ~100 elements belonging to a Revit category (e.g. Walls, Doors, Windows, Structural Columns) with their objectid, name, externalId, and property bag.
When NOT to use: Do not call before translation completes (manifest.status must be success), and do not use for free-text searches across the whole model — filter by category here or use revit_run_schedule for tabular views.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — confirm model_id and that translation has run. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
```

### `revit_get_parameters`

- The name "revit_get_parameters" says "get": a word for reading.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Enumerate the Revit parameters (type + instance) that appear on elements in a given category, or on one specific element by objectid. Returns unique values per parameter and how many elements carry it — ideal for schema discovery before building a schedule.
When NOT to use: Do not use when you just need the elements themselves (use revit_get_elements), or to modify values — this is read-only.
APS scopes: data:read viewables:read (Model Derivative metadata + properties).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — verify model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
```

### `revit_get_sheets`

- The name "revit_get_sheets" says "get": a word for reading.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Enumerate the drawing sheets (title blocks with sheet number + sheet name like 'A-101: First Floor Plan') published from a translated Revit model, so an agent can pick which sheet to render, review, or cross-reference.
When NOT to use: Do not use to list model views like floor plans or 3D views (use revit_get_views) — this returns only 2D sheet entries.
APS scopes: data:read viewables:read (Model Derivative metadata + object tree).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
```

### `revit_get_views`

- The name "revit_get_views" says "get": a word for reading.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
When to use: Return every view (both 2D — floor plans, ceiling plans, elevations, sections, sheets — and 3D — default {3D}, perspective views, isometric views) in the translated Revit model, including each view's GUID, name, role, and whether it is the master view.
When NOT to use: Do not use when you only want drawing sheets (use revit_get_sheets) or element data inside a view (use revit_get_elements / revit_run_schedule).
APS scopes: data:read viewables:read (Model Derivative metadata + object tree).
Rate limits: APS default ~50 req/min per app per endpoint; Model Derivative translation jobs ~60 req/min; OSS uploads size-limited per file to 100MB for direct upload, larger via resumable.
Errors: 401 APS token expired — refresh. 403 scope insufficient — add viewables:read. 404 URN not found — check model_id. 429 rate limited — back off. 5xx APS upstream — retry with jitter.
Side effects: Read-only. Idempotent.
