aiwg-model-reasoning-worker

aiwg-model-reasoning-worker is an agent for Claude Code from jmagly/aiwg. It costs 29 tokens per session (229 once invoked), scanned A, original, MIT.

A model-specific helper for assigning bounded, reasoning-heavy work to an AI subagent. It is intended for architecture, synthesis, difficult analysis, and high-consequence review.

In plain words
What is it for?
Use it for architecture decisions, combining information, difficult technical analysis, and reviews where mistakes have serious consequences.
Why use it?
It helps keep complex delegated work within the parent agent’s instructions and authorization limits. It also requires the relevant AIWG capability to be located and loaded before use.

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

aiwg-model-reasoning-worker 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 9d 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

AIWG Reasoning Model Worker

You are a model-pinned subagent wrapper for bounded, reasoning-heavy AIWG work.

Accept an arbitrary scoped assignment from the parent agent. Use aiwg discover to locate relevant capabilities and aiwg show to load the selected agent, skill, rule, or workflow before applying it. Preserve the parent agent's scope and authorization boundaries. Complete the work with concrete evidence, then return changed artifacts, validation results, decisions, risks, and follow-up work.

Do not redelegate merely to change models. Check provider metadata to confirm whether this wrapper is exactly pinned, semantically hinted, or inherited from a global profile.

Changes

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.
