At a glance

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

  • SKILL.md covers Contract, Snapshot, Live Hooks and Development
  • Runs JavaScript scripts from its folder; calls node and cloudflared; needs BEAM_ACCESS_TOKEN and BEAM_AUTH_TOKEN

What it does

Beam is an agent skill from openclaw/agent-skills. Publish a redacted local coding session to an authenticated read-only Beam catalog.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `README.md`, `package.json` and `references/claude-code-hooks.json`).

The repository describes itself as: Useful skills for agents and claws. The licence is MIT.

Example prompts

  • “/beam”

Requirements

  • Node.js
  • A credential in BEAM_ACCESS_TOKEN
  • A credential in BEAM_AUTH_TOKEN

What it can do on your machine

Read from SKILL.md and the folder at commit 7e73306. 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

    Ships 3 files in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • cloudflared

    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:

    • BEAM_ACCESS_TOKEN
    • BEAM_AUTH_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Beam loads about 1.1k tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 22 tokens; SKILL.md has 428 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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); the scripts in this folder are not scanned.

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.

Show full SKILL.md (163 more words)Show less

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.

Full installation, authentication, data-boundary, and hook documentation: README.md.

Development

bash
node --check skills/beam/scripts/beam
node --check skills/beam/scripts/beam-session.js
node --test skills/beam/scripts/beam.test.mjs

Questions about Beam

What does Beam do?

Publish a redacted local coding session to an authenticated read-only Beam catalog. Beam is an agent skill from openclaw/agent-skills. Publish a redacted local coding session to an authenticated read-only Beam catalog.

How do I install Beam in Claude Code?

Run `npx skills add openclaw/agent-skills --skill beam -a claude-code`. Or copy the skill folder (skills/beam in openclaw/agent-skills) into .claude/skills/beam in your project. Claude Code loads it when a task matches its description.

How do I install Beam in Codex?

Run `npx skills add openclaw/agent-skills --skill beam -a codex`. Or copy the skill folder (skills/beam in openclaw/agent-skills) into .agents/skills/beam in your project. Codex loads it when a task matches its description.

Can I use Beam in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add openclaw/agent-skills --skill beam -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/beam, .gemini/skills/beam, .github/skills/beam and .opencode/skills/beam in your project.

What does Beam need to run?

Going by SKILL.md and its folder, Beam needs JavaScript for the scripts in its folder, the command-line tools its instructions call (node and cloudflared) and credentials named BEAM_ACCESS_TOKEN and BEAM_AUTH_TOKEN. Our summary lists: Node.js; A credential in BEAM_ACCESS_TOKEN; A credential in BEAM_AUTH_TOKEN.

Does Beam access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Beam safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Beam use?

Beam is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Beam use?

About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 210 tokens, read only when the agent opens those files.

What are the alternatives to Beam?

Skills that share tags, products or a category with Beam: Publish (code-yeongyu/oh-my-openagent, 70k stars), Agent Authentication (ruvnet/ruflo, 74k stars), Social Publisher (affaan-m/ECC, 274k stars) and Publish (yc-software/qm, 15k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Beam?

openclaw (a GitHub organization) maintains it in openclaw/agent-skills, which has 1,102 GitHub stars. The repository holds 7 skills in this directory. The repository was last updated on October 7, 2026.
