Use when a mesh arrives from outside — a downloaded STL, a scan, a file from another tool — and is broken, non-manifold, inverted, or fails to load or slice. Also when the user asks to fix, heal, or clean up a model.

Two connected workflows that audit a repo's PRs against its OWN documented AI layer (rules, skills, workflow command definitions) -- not generic code-quality judgment. Workflow A (audit, run via `/pr-trajectory-audit`) reads the repo's own rules/workflow docs, mines PR history for evidence of compliance or violation against them, writes a rubric, installs the live-review GitHub Action, and tells the user the remaining one-time GitHub setup steps. Workflow B (live review) runs automatically on every new PR via CI: deterministic checks first, then Claude reads the PR's actual diff/body against the rubric and posts a review citing the specific documented rule involved, then a human reads that review as part of normal PR review. Findings feed system evolution -- fixing the AI layer, not the one PR. Use when the user wants to "audit my PR history", "check if my agent follows our workflow", "build a trajectory rubric", "review this PR for AI-layer compliance", "pr-trajectory-audit", or is setting up automatic traje
Use when a sliced part is ready to go to the physical printer — sending a job, starting a print, checking what the printer is doing, or confirming which filament is actually loaded. Also when the user asks to "print it", "send it", or what the printer is currently running.
Use when press fits come out wrong, when a hole prints undersize or a peg prints too fat, when the user asks to calibrate the printer or a material, or when an export warns that the calibration has never been measured. Turns caliper readings from a printed fit gauge into a measured calibration record.

Thin skill, thick library. No geometry or measurement logic belongs in this file. Read
PRD.md §6.2 and §9.
The fourth step is the one that matters. A repair that changes a dimension is a failed repair, and it is indistinguishable from a good one by inspection.
An imported third-party model needs its source and licence recorded before it is worked on (PRD §9). Write them next to the file, in the model's own directory:
{"source_url": "...", "author": "...", "licence": "CC-BY-4.0", "downloaded": "2026-08-01"}
If the user cannot say where a file came from or under what terms, say so plainly and ask. A model with unknown provenance is a model you cannot tell them it is safe to publish or sell.
from threedp import features, repair
mesh = features.load_mesh("imported/thing.stl")
print(repair.diagnose(mesh))
Report the diagnosis as it comes: watertight, winding consistency, broken faces, euler number, duplicates, degenerates.
Inversion is named, never reported as a volume. An inside-out mesh encloses a negative
volume — a 60×40×10 plate turned fully inside out measures −23065.76 mm³ — and a checker
comparing that against a range fails correctly for entirely the wrong reason. diagnose says
INVERTED.
result = repair.repair(mesh)
print(result)
repair() never returns a mesh alone. It returns a result with a status:
"It is watertight now" is not a repair verdict. fill_holes fans a non-convex boundary shut,
and a bore breaking a surface is exactly a non-convex boundary — so a bridged bore is watertight,
plausible, and wrong. Report the measured before/after numbers the result carries.
Only result.mesh is safe to export, and only when you have reported the status alongside it.
A repaired mesh is a mesh: no parametrisation, so a press fit on it is unsupported
(CLAUDE.md, "Known accepted gaps") and compensation falls back to a uniform geometric offset
where the hole/outer asymmetry is real and unresolvable. Say that before anyone asks for a fit.
Then: lril3d-inspect to check it against an intent.json, and lril3d-dfm to check whether it
prints. A Z-only scan cannot see angled features, so a repaired angled bore is unverifiable and
the result says so rather than guessing.
Report the status verbatim and both numbers on any dimension that moved. Banned: "cleaned up nicely", "should be fine now", "looks watertight". If the status is UNVERIFIABLE, the sentence is "I could not verify this", not a softer version of PASS.
