At a glance
Registers lifecycle hooks on an agent run to observe, mock or intervene at each step, dispatching them in the order they were registered.
- Observing or logging every step of an agent run
- SKILL.md covers Hook Types, Key Files, Registration and Events, plus 3 more sections
- Needs HOOK_TOKEN
- Mocking a tool call during a test run
What it does
Hooks are registered by passing a hooks array into the agent runner, and a dispatcher stores them per operation, firing sixteen hook types across five categories such as before and after each step. A table of key files maps each concern to its implementation, covering the event types themselves, registration and webhook delivery, local mocks, tool-call context building, tool notifications, step events, human-intervention continuation, terminal completion events and sub-agent events.
A hook can define a local handler function, a webhook, or both; local dispatch always calls the handler, while queued dispatch sends the serialized webhook instead, and only the webhook configuration survives a process restart since functions cannot be serialized. Registrations are cleaned up automatically once an operation completes.
When your agent uses it
- Observing or logging every step of an agent run
- Mocking a tool call during a test run
- Delivering agent events to a webhook instead of a local handler
Example prompts
- “Register a beforeStep hook that logs the current operation.”
- “Set up a webhook hook so queued runs notify our endpoint.”
- “Which file handles human-intervention continuation in the agent runtime?”
What it can do on your machine
Read from SKILL.md and the folder at commit 1863542. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
HOOK_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Runtime Lifecycle Hooks loads about 2.8k tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 799 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 799 words (~2,766 tokens).
“Register lifecycle hooks through execAgent({ hooks }). HookDispatcher stores them per operation and dispatches them in registration order.”

When should I use Agent Runtime Lifecycle Hooks?
Agent Runtime Lifecycle Hooks fits situations like: observing or logging every step of an agent run; mocking a tool call during a test run; delivering agent events to a webhook instead of a local handler.
How do I install Agent Runtime Lifecycle Hooks in Claude Code?
Run `npx skills add lobehub/lobehub --skill agent-runtime-hooks -a claude-code`. Or copy the skill folder (.agents/skills/agent-runtime-hooks in lobehub/lobehub) into .claude/skills/agent-runtime-hooks in your project. Claude Code loads it when a task matches its description.
How do I install Agent Runtime Lifecycle Hooks in Codex?
Run `npx skills add lobehub/lobehub --skill agent-runtime-hooks -a codex`. Or copy the skill folder (.agents/skills/agent-runtime-hooks in lobehub/lobehub) into .agents/skills/agent-runtime-hooks in your project. Codex loads it when a task matches its description.
Can I use Agent Runtime Lifecycle Hooks in Cursor, Gemini CLI or GitHub Copilot?
