## Description

Publish a redacted local coding session to an authenticated read-only Beam catalog.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Beam

Use when the user explicitly asks to beam, publish, or share the current local coding session with an authenticated OpenClaw receiver.

## Contract

- Treat invoking this skill as approval for one snapshot upload to the named destination.
- Never upload raw JSONL, reasoning, system/developer prompts, tool output, environment values, credentials, browser state, cookies, or local paths.
- The helper is self-contained: it resolves and parses exact Claude Code or Codex transcripts, then uploads only locally redacted user/assistant messages and compact tool counts.
- Beam is a read-only projection. Do not connect a node, expose a terminal, resume the local harness remotely, or grant the receiver filesystem/tool access.
- Require HTTPS except for loopback development endpoints.
- Authenticate with `BEAM_ACCESS_TOKEN`, `BEAM_AUTH_TOKEN`, or an interactive `cloudflared access login`. Never print those values.
- Live synchronization is opt-in persistent behavior. Do not install hooks unless the user explicitly asks for live Beam updates.

## Snapshot

Set or obtain the destination receiver URL first:

```bash
export BEAM_ENDPOINT="https://example.internal/api/v1/beam/sessions"
```

Prefer the harness-specific exact identifier. Resolve the directory containing this `SKILL.md` as `BEAM_SKILL_DIR` first.

Claude Code exposes the current session id:

```bash
node "$BEAM_SKILL_DIR/scripts/beam" publish \
  --endpoint "$BEAM_ENDPOINT" \
  --session-id "${CLAUDE_SESSION_ID}"
```

In Codex, resolve the directory containing this `SKILL.md` as `BEAM_SKILL_DIR`; normal shell-tool children expose the current thread id:

```bash
node "$BEAM_SKILL_DIR/scripts/beam" publish \
  --endpoint "$BEAM_ENDPOINT" \
  --thread-id "$CODEX_THREAD_ID"
```

Prefer exact harness metadata when available:
