SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00951 |
| Opus 5 | $0.00016 | $0.00476 |
| Sonnet 5 | $0.00006 | $0.00190 |
| Haiku 4.5 | $0.00003 | $0.00095 |
Grade A, and why
map-perf scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Map performance
Run when pnpm design:route includes map-perf. It proves the changed topology
gesture's work cost; add the separate motion change fact when temporal output
also changed.
This skill exists because a 2026-07-31 node-drag report was dismissed six times while the measurement was actually panning the background. The two gestures look the same from outside.
Why grabbing a node is difficult
| Node drag | Background pan | |
|---|---|---|
| Cursor | grabbing |
grabbing |
| Visible motion | one node | whole map |
| Physics | reheats through heatRef |
remains idle |
| Measured cost at 3,000 nodes | about 140 ms/frame | about 2 ms/frame |
A pointer cursor is not proof of a grab. If sim.hasNode() is false, capture
fails silently and becomes a pan.
Instrumentation: ?e2e=1
The query enables a test-only window.__atlasMap surface:
window.__atlasMap.nodes()
// [{ id, kind, label, x, y, draggable, hidden, radius, agentFocus }]
window.__atlasMap.interaction()
// { kind: "node" | "pan" | "idle", nodeId }
// Call during the gesture. A "pan" result invalidates the sample.
window.__atlasMap.backing()
// { width, height, dpr }
It also exposes edges(), edgeAt(), camera(), selection(), and chips().
Implementation: the final effect in
src/widgets/ontology-map/ui/use-topology-loop.ts.
Procedure
pnpm build && npx serve out -l 4173
node scripts/perf-node-drag.mjs
Discard output unless the harness explicitly reports a successful node grab.
Four rules
- Use real CDP mouse input through
page.mouse.*. Synthetic PointerEvents are untrusted, cannot capture the pointer, and become pans. - Run headed. Headless rendering lacks display vsync and compositor backpressure; it measured 44fps where the real device measured 7fps. Only JS work cost transfers reliably.
- Report
work, not framegap. Gap includes refresh rate and CDP round trips (about 24ms); work is time owned by Atlas. - Measure a control group such as
synth=31besidesynth=3000. The observed 139.9ms versus 1.0ms exposes size-dependent cost directly.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

map-perf is a skill published in the GitHub repository wlsdks/ontology-atlas (100 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 951 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
