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 | $0.00054 | $0.01983 |
| Opus 5 | $0.00027 | $0.00992 |
| Sonnet 5 | $0.00011 | $0.00397 |
| Haiku 4.5 | $0.00005 | $0.00198 |
Grade A, and why
frontend-standards 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 8d ago.
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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend standards (mostly ESLint-enforced)
Authoritative: docs/DESIGN_SYSTEM.md, docs/PATTERNS.md.
Ports & adapters (HIGH if violated)
- No
window.api.*infeatures/,routes/,components/— use service hooks fromrenderer/services/(React Query). ESLint errors on direct access. - Data fetching — React Query via service hooks only; no
useState + useEffectfor remote data.
React Query & async mutations (HIGH on correctness)
- Invalidation must match —
invalidateQueries({ queryKey })is a prefix match; a key factory that appends a trailingundefined/optional segment (keys.x.y()→['x','y',undefined]) will not match the typed queries (['x','y','viewed']). Fix it with the correct key: the shorter prefix (['x','y']), or a deliberatepredicate— noteexact: truedoes not fix it (an exact match on the wrong shape['x','y',undefined]still misses['x','y','viewed']). After a mutation, confirm the key you invalidate hits the queries that render the affected UI (#486: shipped this twice → stale viewed/saved badges). - Mutations — never show success / apply optimistic state / emit tracking events before the mutation resolves. Two cases: (a) awaited —
await mutateAsync(), then run the success effects, intry/catch; (b) detached (void/fire-and-forget) — attach a.catchsurfacing a fixed@ajh/translationserror key (never rawerr.message) and put the success effects in.then, not on the line after the call. - Nullable at the IPC boundary — guard a contract-optional/
nullvalue (a field a command may return absent) before string/array ops (.toLowerCase()/[0]/.split()).
Design system
- Tokens —
text-brand/bg-brand/border-brand/ring-brand; CSS varsvar(--color-brand). No[#RRGGBB]in className. - Motion —
import { transition } from '@ajh/ui'(.fast/.normal/.relaxed/.slow/.spring/.modal/.overlay); no inline{ duration, ease }. - Primitives —
@ajh/ui(Button,Input,TextArea,SelectDropdown,ModalShell,GlassCard,EmptyState, …). No raw<button>/<select>/<textarea>(exception:<input type="range|file|checkbox|radio|hidden">). - Imports — import
@ajh/uidirectly, not@/components/ui/*(exceptUpdateBanner).
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.

frontend-standards is a skill published in the GitHub repository saeedkolivand/ai-job-hunter-app (55 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 1,983 once invoked, about $0.0003 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 2026-09-03.
