graphics-architecture (Graphics and Peony; skill maturity: planning-gated).
Define display backends, software buffers/rendering, formats, damage, synchronization, scaling, and future acceleration.
Use for requests mentioning graphics, framebuffer, display buffer, software renderer, or when a dependency points to this skill. Load only after repository entry and before design or implementation.
Requires isolated userspace, IPC, input, and a display resource path. Do not load it only because a future FinnOS document mentions the subsystem.
task-planningcross-architecture-designperformance-engineeringRead the full prerequisite closure in topological dependency order. If one cannot be satisfied, move the task to Blocked or Deferred; do not omit the dependency.
Conditional skills:
Implementation gates are roadmap/runtime conditions, not additional documents to load automatically:
UI_GUIDELINES.mddocs/architecture/peony.mdHARDWARE_SUPPORT.mdRe-read implementation and tests referenced by those documents. The documents establish intent/status boundaries, not runtime proof.
Only GOP metadata and a full-screen kernel fill exist; no display driver, renderer, buffer protocol, or multi-display support.
Registry verification used base commit d21a477 plus the dirty worktree context "base commit plus uncommitted audit and agent-system worktree" on 2026-07-16. This is not an integrated-revision claim. Reverify after HEAD, active PRs, or relevant source changes.
git status, recent history, active related issue/PR, and selected roadmap item.An evidence-backed graphics architecture result with scoped artifacts, tests, documentation, and handoff. Include acceptance evidence, residual limitations, and next dependency rather than only code.
./tools/finn check
Run commands from the repository root. A command listed here is a baseline/gate, not evidence that absent future functionality has a runnable target.
State shared semantics explicitly; isolate x86-64 and ARM64 mechanisms.
State guest architecture separately from host architecture and emulator model. Maintain a parity row for changed semantics and document intentional differences.
Preserve the boundary described by the current state: Only GOP metadata and a full-screen kernel fill exist; no display driver, renderer, buffer protocol, or multi-display support. Apply .agents/checklists/pre-change.md; for kernel, driver, security, architecture, or UI work also apply the matching checklist.
Make Defer GPU/multi-display until reference workload and driver model observable with a negative case, then run the narrow and aggregate gates. Do not permanently hard-code test counts; counts belong to dated evidence reports.
Update the canonical behavior/status document, relevant architecture/reference material, test/build instructions, limitations, and this skill registry if any command, gate, or current-context statement changes.
Gate on userspace/IPC/display ownership before relying on downstream assumptions.Use .agents/templates/handoff-template.md. Include objective, starting/final Git state, task state, skills used, files, exact commands/results, evidence classification, docs/status changes, unknowns, blockers, risks, next action, and next skills. Distinguish locally verified worktree changes from integrated behavior.
Request: "Work on graphics." Correct response: begin by gate on userspace/ipc/display ownership, then define buffer format/stride/ownership/lifetime, and require evidence for defer gpu/multi-display until reference workload and driver model before changing status. Incorrect response: create a plausible subsystem scaffold and mark the roadmap item complete because it compiles.
Canonical source: .agents/scripts/skill_registry.py. Increment version for material policy/workflow/gate changes, update last_verified only after reinspection, run python3 .agents/scripts/render_skills.py, review generated diffs, then run python3 .agents/scripts/validate.py --all. Follow .agents/GOVERNANCE.md; never hand-edit generated skills.
