figmirror-dc3604 — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited figmirror-dc3604 (Agent Skill) and scored it 74/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 2 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Enable references/three-d-prompting.md only when the user asks for a 3D figure, the reference is visibly 3D, or the parsed data requires a 3D encoding such as x/y/z, surfaces, trajectories, layered profiles, closed objects, 3D small multiples, 3D bars, or plane projections. Do not use this insert to turn an ordinary 2D task into 3D.

figmirror-drawer custom subagent through theTask tool with subagent_type="figmirror-drawer" and run_in_background=false. It writes each iteration's matplotlib script, render, notes, and floor self-check in the staged workdir.
figmirror-reviewer custom subagent through theTask tool with subagent_type="figmirror-reviewer" and run_in_background=false. It sees only the staged audit view: the far-view composite, full-resolution reference/draft near views, the Reviewer prompt, the aesthetic library, fixed diagnostics, and optional fixed 3D audit material. It returns strict JSON including boxes; figannot.py review-decision validates and records the result before any Drawer or finalization decision. The Task tool carries a single text prompt and has no attachment channel, so the Orchestrator gives the Reviewer an ordered list of absolute image paths and the Reviewer opens each one with Read, once, in that order.

references/three-d-prompting.mdplus references/three-d/ beside the normal prompts. The router selects exactly one mode file: three-d/style-transfer.md for ordinary user-data figures, or three-d/strict-reproduction.md for reproduction, comparison, or candidate/control replacement. For strict 3D reproduction runs that need quantitative candidate diagnosis, also stage scripts/score_3d_candidates.py; do not use that scorer for ordinary style transfer. The top-level Orchestrator owns final selection and must run the selected mode's rendered-image gates before copying any candidate to the final figure. Always stage scripts/figannot.py; it is the deterministic operator for building audit composites and drawing Reviewer boxes.
references/orchestrator-claude.md anddispatches figmirror-drawer for each iter. Every Drawer prompt includes the exact trace line Iter: <N> with the current non-negative decimal iteration. The Drawer writes figure_iter<N>.py, img_iter<N>.png, notes_iter<N>.md, and floor_selfcheck_iter<N>.txt; the Orchestrator verifies those files before any Reviewer handoff.
audit_view_<N>, run scripts/figannot.py compose to createcomposite.png and review_prompt.txt, fit the staged near views with scripts/fit_images.py, and dispatch figmirror-reviewer as described in references/orchestrator-claude.md. List composite.png, reference_clean.png, and draft_fullres.png as an ordered set of absolute paths for the Reviewer to Read exactly once each; append the optional strict-3D accepted control as a fourth entry when present. The Reviewer sees only those images plus the aesthetic library, fixed diagnostics, and optional 3D insert, then returns strict JSON without re-reading an image it has already opened, and without reading review/Drawer history.
scripts/figannot.py review-decision after every Reviewer result. Aclean result before the run reaches min_reviews total valid Reviewer calls starts another Reviewer on the same immutable draft with no Drawer in between. Actionable feedback permits scripts/figannot.py draw --max-iters <max_iters> and another Drawer when below the hard max_iters cap. The helper must succeed before spawning that Drawer. A missing, malformed, empty, or inconsistent Reviewer result returns retry_reviewer: it does not count, never triggers Drawer, and starts one fresh Reviewer on the same immutable draft. A second consecutive invalid result fails closed. Pass both --min-reviews and --max-iters to every review-decision invocation, plus --strict-3d when the router selected three-d/strict-reproduction.md.
ship: the quality floor passed,the verdict is clean, and at least min_reviews valid Reviewer calls have completed across the run. Default max_iters=5; it is always a hard Drawer cap. If the gate returns stop_at_cap, do not draw again: select under the existing hard-cap policy and finalize an existing iteration.
