metashape-api-lookup — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited metashape-api-lookup (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.
text (not bash) so it reads as prose, not a command.```bash

When working on metashape-mcp tools, always verify API parameters against the local reference files rather than guessing.
The project contains these Metashape API references:
| File | Contents | When to Use |
|---|---|---|
api_reference.txt | Full Python API reference (text, searchable) | Primary reference for parameter names, types, defaults |
metashape_python_api_2_3_0.pdf | Official PDF API docs | Backup if text version is unclear |
metashape-pro_2_3_en.pdf | Metashape Pro user manual | For understanding workflow context and UI equivalents |
usgs_ofr20211039.pdf | USGS photogrammetry best practices | For filtering thresholds and workflow order |
When implementing or modifying an MCP tool:
Grep for: "chunk.buildModel" or "buildModel" or "Chunk.buildModel" Grep for: "SurfaceType" or "DataSource" or the specific enum classkeep_keypoints: Metashape default=False, MCP default=True (required for incremental alignment)blending_mode: Use "natural" for best quality, not necessarily the API defaultThese are verified facts from the API reference — do NOT guess these:
| Topic | Correct Answer |
|---|---|
alignChunks method param | Plain int (0=tiepoints, 1=markers, 2=cameras), NOT an enum |
RasterFormatTiles | IS the correct enum for GeoTIFF export — there is no RasterFormatGeoTIFF |
face_count param | Use Metashape.CustomFaceCount with face_count_custom=0 for unlimited |
cam.meta["key"] | Bracket access only — MetaData is C++ object, no .get() method |
chunk.tie_points.points | Can be None — always check before len() |
classifyGroundPoints | On chunk.point_cloud, NOT on chunk directly |
exportRaster | Handles both DEM and orthomosaic (use source_data parameter) |
progress callback | Callable[[float], bool] — return True to continue, raise to cancel |
