dynamo: Skill for Claude Code

.agents/skills/dynamo-frontend-benchmark/SKILL.md

dynamo-frontend-benchmark is a skill for Claude Code, Codex from ai-dynamo/dynamo. It costs 98 tokens per session (3,791 once invoked), scanned B, original, no licence file.

A way to measure and profile Dynamo's frontend, including its HTTP handling, tokenizer, key-value router, and mock workers. Profiling shows where time or processing capacity is being used.

In plain words
What is it for?
Use it to compare frontend versions, measure latency and throughput, and profile frontend or mock-worker workloads on and off the CPU.
Why use it?
It helps reveal throughput, response-time, and CPU bottlenecks before or after a frontend change.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is ai-dynamo/dynamo's own configuration. It tells Claude Code and Codex how to work on dynamo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dynamo configures →

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 →

    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

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.

Security

Grade B, and why

dynamo-frontend-benchmark scanned grade B 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 2mo ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/analyze_folded.py, scripts/capture_offcpu.sh, scripts/env.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.

dynamo-frontend-benchmark is a skill published in the GitHub repository ai-dynamo/dynamo (8,412 stars, last pushed today), with no licence file. It adds 98 tokens to every session and 3,791 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
