The full skill.

Original instructions from the publisher’s SKILL.md

# 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:

- Claude Code: `${CLAUDE_SESSION_ID}` identifies the current local conversation; the helper finds its transcript.
- Codex shell tools: `CODEX_THREAD_ID` identifies the current thread.
- Hook adapters: pass their JSON to `beam hook`; `transcript_path` is authoritative.
- Exact fallback: Beam scans only the native Claude/Codex session roots for the supplied id and fails closed on no match or ambiguity.

Useful options:

```bash
node "$BEAM_SKILL_DIR/scripts/beam" publish --endpoint "$BEAM_ENDPOINT" --session /path/to/session.jsonl
node "$BEAM_SKILL_DIR/scripts/beam" publish --endpoint "$BEAM_ENDPOINT" --thread-id "$CODEX_THREAD_ID"
node "$BEAM_SKILL_DIR/scripts/beam" publish --endpoint "$BEAM_ENDPOINT" --title "Fix upload flow"
node "$BEAM_SKILL_DIR/scripts/beam" publish --endpoint "$BEAM_ENDPOINT" --complete
node "$BEAM_SKILL_DIR/scripts/beam" publish --endpoint "$BEAM_ENDPOINT" --dry-run
```

`--dry-run` prints the sanitized payload locally and performs no network request.

On success, return only the Beam URL and a short disclosure summary: source harness, shared message count, whether older entries were truncated, and whether the beam is complete. The URL uses the endpoint-derived Control UI base path followed by `/beam/<title-slug>-<id-prefix>`, for example `https://gateway.example.com/beam/fix-upload-flow-0123456789ab`. The title comes from `--title` or the first shared user message. The stable ID suffix identifies the session; links with an earlier title remain valid.

The helper also accepts bare `/beam/<id-prefix>` links and, during rollout, the current server's exact `/chat/<agent>?catalog=beam&host=gateway&thread=<full-beam-id>` response. It still rejects the obsolete `?session=catalog:...` beta form.

## Live Hooks

The helper accepts the snake_case JSON emitted by both Claude Code and Codex lifecycle hooks:

```bash
node "$BEAM_SKILL_DIR/scripts/beam" hook --endpoint "$BEAM_ENDPOINT" --quiet
```

Configure root `Stop` hooks for turn-by-turn updates. Claude Code can also use `SessionEnd` for finalization; Codex finalization uses an explicit `publish --complete`. See:

- `references/claude-code-hooks.json`
- `references/codex-hooks.toml`

Hook failures must not block the coding session. Keep them quiet on success; log one concise redacted error on failure.
