beam

beam is a skill for Claude Code from openclaw/agent-skills. It costs 21 tokens per session (1,881 once invoked), scanned A, original, MIT.

A tool for publishing a redacted local coding session to an authenticated, read-only Beam catalogue.

In plain words
What is it for?
Use it when explicitly asked to beam, publish, or share the current coding session with an authenticated Beam receiver.
Why use it?
It lets others view a safe summary without exposing raw transcripts, prompts, credentials, cookies, or terminal access.

About the project

OpenClaw Agent Skills is a shared repository of reusable workflows for coding agents working on OpenClaw projects. It provides skills for activities such as code-review closeout, behavior validation, session handoff, remote testing, transcript provenance, and viewing agent sessions. The catalogue entries are the project’s distributed skills and instruction.

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

beam 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 2d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/beam-handoff.js, scripts/beam-handoff.test.mjs, scripts/beam-session.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.
  • Ordinary publishing shares a read-only snapshot. A separately requested handoff releases the source Beam identity and moves its logical conversation to Team. After handoff, use Beam's authenticated read and continue commands for subsequent work; do not resume independent source work or publish another transcript copy.
  • Team owns one durable conversation after release. The source history imports once; reads, reconnects and continuations resolve that same conversation. Native provider runtime IDs need not survive. Do not connect a node, expose a terminal, transfer credentials or grant filesystem/tool access.
  • Require HTTPS except for loopback development endpoints.
  • Guests use their existing personal Cloudflare Access sign-in or BEAM_ACCESS_TOKEN; never request, share, or copy a Gateway token for guest uploads. BEAM_AUTH_TOKEN remains the ordinary operator Gateway-auth fallback, not a guest credential. Never print token 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:

export BEAM_ENDPOINT="https://gateway.example.com/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:

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

Changes

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.
