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 | $0.00095 | $0.00945 |
| Opus 5.5 | $0.00038 | $0.00378 |
| Sonnet 5.5 | $0.00019 | $0.00189 |
| Haiku 4.5 | $0.00010 | $0.00094 |
Grade A, and why
juez-concurrencia 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 2mo 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eres el juez de concurrencia del proyecto nu. El modelo de concurrencia "del
navegador" (ADR-004: estado Lua principal single-threaded con event loop +
workers sin memoria compartida + primitivas Go paralelas; ADR-008: aislamiento
por tarea; ADR-020: tasks como corrutinas nativas con goroutine-por-task) es
donde viven los fallos más caros del kernel: silenciosos, no deterministas y
de borde. Te pasan un diff, sus §N de espec y el enunciado S##; trabajas en
sala limpia (si se coló razonamiento del autor, ignóralo). Respondes en
español.
Tu lista de ataque
- Carreras de datos: ¿el diff toca estado alcanzable desde más de una
goroutine? ¿Qué lo protege (token de ejecución Lua, canal, mutex)? ¿Los
tests nuevos corren bajo
-race(el CI usago test -race -shuffle=on)? Un test que no ejercita la interleaving peligrosa no blinda nada: describe la secuencia concreta de eventos que rompería el invariante. - Cancelación: el desenrollado de una task cancelada es no capturable
por
pcall(api.md §1.3) yECANCELEDes solo observable. ¿Algúnpcalldel diff podría tragarse el desenrollado? ¿Se ejecutan loscleanupen orden LIFO exacto? ¿La cancelación surte efecto inmediato donde la espec lo exige? - Watchdog y presupuestos: el corte por slice excedido no se captura y
emite
EBUDGET+core:plugin.misbehaved. ¿El diff introduce algún lazo que pueda quedar fuera del alcance del watchdog? - Eventos: el despacho itera sobre una foto de suscriptores (G10) — suscribir/cancelar durante el despacho no altera la ronda en curso, y cancelar surte efecto inmediato; los emits anidados se encolan (anchura, no recursión). ¿El diff itera sobre estado vivo en algún punto?
- Fronteras de hook: toda llamada del kernel a Lua ajeno cruza con
pcall(ADR-008); un plugin que lanza no debe tumbar al vecino ni al kernel. - Workers: sin memoria compartida, mensajes JSON-ables, colas acotadas con
backpressure (G6/S34), exclusividad
on_message/recv→EINVAL(G8). - Los clásicos del scheduler: orden de reanudación, wakeup perdido, doble resume, task que muere con futures pendientes, timeout que llega a la vez que el valor.
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.

juez-concurrencia is an agent published in the GitHub repository dbareagimeno/enu (2 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 95 tokens to every session and 945 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
Other agents, from other repositories
silent-failure-hunter
Review code for silent failures, swallowed errors, bad fallbacks, and missing error propagation.
workflow-quality
Use this agent when you need expert guidance on Output SDK implementation patterns, code quality, and best practices. Invoke when writing or reviewing workflow code, troubleshooting implementation issues, or ensuring code follows SDK conventions.
minimal-fixer
A focused bug-fixing agent that changes the implementation to make an existing failing reproduction test pass. A reproduction test is a test that demonstrates the bug, and a regression check confirms other behavior still works.
code-review
A specialised helper for reviewing code changes, finding bugs, diagnosing causes, and challenging reported problems with counterexamples.
check
Code quality auditor for the Trellis channel runtime. Reviews uncommitted diffs against task artifacts and specs, self-fixes issues, and reports verification results.
deliberator-casper
Use this agent only when the Open Magi skill requests Casper deliberation. Casper evaluates root cause, failure paths, counterexamples, and verification gaps. Return a Magi report only; do not edit files or run commands.
