aithy: Skill for Claude Code

.claude/skills/ax-agent-rlm/SKILL.md

ax-agent-rlm is a skill for Claude Code from dosco/aithy. It costs 88 tokens per session (7,356 once invoked), scanned A, a copy of ax-agent-rlm, Apache-2.0.

A coding guide for AxAgent's runtime where an agent can execute code and ask a language model for help during a task. It covers runtime context, prompt controls, recursion, and limits on generated output.

In plain words
What is it for?
Use it when building AxAgent code-execution workflows, semantic helper calls with llmQuery, runtime context policies, recursive agents, or agent tests.
Why use it?
It helps keep large inputs and long-running agent work manageable while controlling what enters prompts, what stays available at runtime, and how much execution is allowed.

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

ax-agent-rlm 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 3d 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.

AxAgent RLM Runtime Rules (@ax-llm/ax)

Use this skill for code-runtime agents and llmQuery(...) semantic-helper behavior. For ordinary agent setup, child agents, tool namespaces, clarification, and bubbleErrors, use ax-agent. For callbacks and logs, use ax-agent-observability. For memories and skill loading, use ax-agent-memory-skills.

Use These Defaults

  • Use agent(...), not new AxAgent(...).
  • In stdout-mode RLM, use one observable console.log(...) step per non-final actor turn.
  • Rely on autoUpgrade (ON by default) for oversized inputs you did not declare in contextFields: any input value over ~8k serialized chars is kept runtime-only automatically, with a 1,200-char prompt preview plus a contextMetadata line, while the full value stays live in the runtime as inputs.<field>. Declare a field in contextFields only when you want a specific inline policy (promptMaxChars / keepInPromptChars) or need a large required non-string field kept out of the prompt (those are left inline by auto-upgrade).
  • Default to contextPolicy: { preset: 'checkpointed', budget: 'balanced' } for most RLM tasks.
  • Prefer contextPolicy: { preset: 'adaptive', budget: 'balanced' } when older successful turns should collapse sooner while live runtime state stays visible.
  • Use contextMap for recurring long-context corpora when the distiller should start future runs with a small persisted orientation cache.
  • Prefer promptLevel: 'default' for normal use.
  • Use promptLevel: 'detailed' when you want extra anti-pattern examples and tighter teaching scaffolding in the actor prompt.
  • Prefer executorModelPolicy when the actor may need to upgrade after repeated error turns or discovery in specific namespaces without also upgrading the responder.
  • Use explicit child agents in functions: [...] when the task needs specialist agents with their own tools/runtime.
  • Use llmQuery(...) only for focused semantic questions over narrowed context; it does not spawn a tool-using child AxAgent.
  • Prefer maxSubAgentCalls only when you need an explicit cap on llmQuery(...) sub-query usage.

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.
