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 A, and why

runex 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 5d 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.

Runex Workflow Engine

Runex is a single-binary Elixir workflow orchestrator. It parses TOML (primary) and YAML workflow definitions, builds a DAG of steps, and executes them via pluggable drivers. It runs in standalone mode (SQLite, default — no configuration required) or federated mode (Postgres + libcluster) for multi-node deployments.

Verified against lib/runex/driver.ex's @drivers map (single source of truth for valid driver = values, Runex.Driver.names/0) — 14 registered drivers:

  • command: shell, mise, nushell
  • agent: agent, altana, awman, codex, antigravity, claude
  • workflow: workflow, runex (module Runex.Drivers.RunexSub)
  • container: container, flame
  • wasm: wasm

The 14 names are the flat @drivers map; the class labels above come from execution_class/1's module doc comment, not from the function's actual runtime behavior — that function's "workflow" guard clause matches the literal string "runex_sub", not the registered driver name "runex", so execution_class("runex") actually falls through to "other". This looks like an upstream naming-drift bug (the guard clause not being updated when the driver was registered as "runex" rather than "runex_sub"), not a documentation error here.

Current documented version: 0.0.7 (mix.exs @version). Legacy templates for older deployments remain under templates/0.1.0/ and scripts/0.1.0/.

Anti-fabrication

This skill follows core:anti-fabrication. Runex is a workspace-owned strategic surface with the fastest cadence this marketplace documents, so every claim above the fold is checked against the source tree rather than release notes. Verified against runex 0.0.7 (mix.exs @version, re-confirmed 2026-08-04, claude-skills-223): the driver list was corrected from 8 to the real 14 registered in Runex.Driver.@drivers, and workflow path resolution was corrected from 3 to the real 4 search roots in Paths.workflows_dirs/ 0. A Gate 3 pass then caught the execution_class/1 naming-drift documented above as an upstream bug, not a doc error (filed separately, claude-skills-239). Re-verify against the live lib/runex/driver.ex and mix.exs @version before asserting a driver name or version this skill doesn't cover — this is the fastest-moving source in the repo.

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.

runex is a skill published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed 3d ago), licensed MIT. It adds 56 tokens to every session and 2,876 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 2026-09-04.
