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 | $0.03397 | $0.03397 |
| Opus 5.5 | $0.01359 | $0.01359 |
| Sonnet 5.5 | $0.00679 | $0.00679 |
| Haiku 4.5 | $0.00340 | $0.00340 |
Grade A, and why
claude-jev AGENTS.md scanned grade A with 1 finding 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 2d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
`urllib.request` is the HTTP client. How it starts
The opening of the file, as written. The whole thing — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claude-jev
A Claude Code plugin. Five hooks send small judgments to TypeSafe's Jev, a
System One model that returns typed answers instead of text. README.md
explains what each hook decides and why. Read it before changing behavior.
Vision
VISION.md is the acceptance policy for what this plugin becomes and refuses to
become. Check a non-trivial change against its align/resist pair before
building it, and cite it when resisting.
Layout
| Path | What lives there |
|---|---|
scripts/jev.py |
API client and CLI. Every other script imports it. |
scripts/prompt_router.py |
Measurement reference for the routing eval; production runs src/prompt-router.ts under node type stripping |
scripts/rules.py |
PostToolUse on edits, PreToolUse/PostToolUse on Bash to record shell writes, and Stop — rule enforcement |
hooks/register.ts |
Experimental function-hooks module: session.compact -> node --experimental-strip-types src/compactor.ts rows, and the /claude-jev settings pane. A bridge, not a second implementation. |
src/ |
The TypeScript hook implementations the plugin runs, executed directly as source under node type stripping (needs node >= 22.18) |
adapters/afk/ |
The AFK host adapter: a TypeScript implementation of the same hooks with its own manifest, hooks.json, and README. Its known-gaps list is the contract — do not claim parity that table does not state. |
scripts/comparators.py |
ast-grep lookups the rule hook adds to a judgment |
scripts/observed.py |
Scores what a past turn actually did |
scripts/stats.py |
The Stats row in /claude-jev, or python3 scripts/stats.py — scores live decisions from the three logs under ~/.claude: jev-router-log.jsonl (router, subagent, rules), jev-compact-log.jsonl, jev-calls.jsonl (every API call, written by jev.ask) |
scripts/check_no_comments.py |
Hard ban: fails if scripts/, eval/, or hooks/ source has a # / // / /* */ comment |
eval/ |
Offline measurement. See eval/README.md. |
.claude/skills/ |
Maintainer skills for this repository, not shipped. release cuts a version: changelog section to bump, tag, push, GitHub release. |
hooks/hooks.json |
Hook registration. New hook means an entry here. modules names the function-hooks module; older Claude Code ignores the key. |
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.

claude-jev AGENTS.md is an instructions file published in the GitHub repository 0x7067/claude-jev (19 stars, last pushed 2d ago), licensed MIT. It adds 3,397 tokens to every session, about $0.0136 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.
