Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00054 | $0.00324 |
| Opus 5 | $0.00027 | $0.00162 |
| Sonnet 5 | $0.00011 | $0.00065 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
preflight 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 3d 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.
What it actually says
Preflight
On-demand replacement for disabled husky gates. Run from repo root. Fix failures before continuing; do not skip unless the user says so.
Steps
- Typecheck (web + backend + callback):
pnpm typecheck
- React Compiler bailouts:
pnpm compiler:check
- Lint (whole tree; former lint-staged scope was staged files only):
pnpm lint
- Commit hygiene (manual — hooks are off):
- No
Co-authored-by: Cursor/Made-with: Cursorin commit messages - No stray lone
@line in the message (PowerShell here-string leak)
- No
Notes
- Do not run
convex codegenas part of preflight (uploads to the linked deployment). - Husky hooks under
.husky/are commented out on purpose; re-enable there if you want gates back on every commit/push. - Optional format pass on dirty files:
./node_modules/.bin/lint-staged(needs staged files) or Prettier on specific paths.
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.

preflight is a skill published in the GitHub repository vvedantb/eva (101 stars, last pushed 4d ago), licensed MIT. It adds 54 tokens to every session and 324 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 2026-08-30.
