agent-infra: Agent for Claude Code

.claude/agents/agent-infra-lifecycle-executor.md

agent-infra-lifecycle-executor is an agent for Claude Code from fitlab-ai/agent-infra. It costs 23 tokens per session (76 once invoked), scanned A, original, MIT.

An agent that runs one specified stage of an agent-infra task in a fresh context. It follows the selected stage’s instructions and stops after that stage finishes.

In plain words
What is it for?
Use it to execute one non-review lifecycle skill for a referenced task while preserving the current working tree.
Why use it?
It keeps a task stage focused and avoids accidentally running review stages or changing unrelated work in the existing project files. A fresh context can also isolate the stage from earlier conversation details.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is fitlab-ai/agent-infra's own configuration. It tells Claude Code how to work on agent-infra 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 agent-infra configures →

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

agent-infra-lifecycle-executor 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 7d 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 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.
