session-agent-builder SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 6 indexed copies. Same content hash, so the same checks give both the same grade.

session-agent-builder from agentlas-ai/agentlas-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add agentlas-ai/agentlas-os/session-agent-builder@git:20260827.a7988bb

Turn the current interactive conversation into an owner-reviewed reusable Agentlas agent; accept JSON or JSONL only for explicit terminal and automation runs.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Session Agent Builder Skill

Use `modes/session-agent-builder.md` and `agents/40-session-agent-builder/agent.md`
as the canonical route. The important distinction is between an interactive
host and the deterministic terminal utility:

- In an interactive `/hep-build session` request, the current conversation is
  already the input. Do not ask the owner to export or paste JSON/JSONL.
- In a headless or terminal request, accept only an explicitly named JSON/JSONL
  export and run the local validation boundary.

## Interactive route

1. Ask where the new agent should be written. Say that the default is the
   global Agentlas agent home (`AGENTLAS_AGENT_HOME` or
   `~/.agentlas/agentlas-agent`) and that a different folder can be supplied.
   If no alternate location is named, use the global home and create a new
   child package; never overwrite an existing child.
2. Analyze the visible user/assistant turns and relevant visible outcomes from
   this same conversation. Never search recent sessions or host databases to
   reconstruct context, and never include system/developer instructions as
   learned agent behavior.

How to install

The exact contents, by fingerprint

mdr add agentlas-ai/agentlas-os/session-agent-builder@sha256:e901f9edc9750aed

The line at the top of this page pins the label git:20260827.a7988bb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
