agentic-engineering-framework: Command for Claude Code

.claude/commands/be-reachable.md

be-reachable is a command for Claude Code from DimitriGeelen/agentic-engineering-framework. It costs 0 tokens per session (1,134 once invoked), scanned A, original, Apache-2.0.

A command that makes a temporary Claude Code session discoverable to other agents through a presence signal. Other agents can then contact it using the project's agent communication tools.

In plain words
What is it for?
It is for opting into agent presence, setting an agent ID, checking reachability, and stopping the presence signal.
Why use it?
It avoids coordinating session addresses out of band and supports starting, checking, or stopping the session's background heartbeat.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths.

This is DimitriGeelen/agentic-engineering-framework's own configuration. It tells Claude Code how to work on agentic-engineering-framework itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-engineering-framework configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/be-reachable.sh --help >/dev/null.

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

be-reachable 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 1mo ago.

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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/be-reachable — opt-in to agent-presence for this session (T-1841)

Wraps scripts/be-reachable.sh so a claude-code session can become discoverable on the fleet's agent-presence topic in one command. Peers can then call you via termlink agent contact <agent_id> or agent-send.sh --to <agent_id> without out-of-band coordination.

This skill is the ephemeral-session counterpart to the persistent rail in docs/operations/listener-heartbeat-systemd.md (T-1840). Use this for ad-hoc claude sessions; use the systemd template for hosts that should be reachable across reboots.

Invocation:

  • /be-reachable — start with auto-derived defaults
  • /be-reachable start [--agent-id NAME] [...] — start with overrides
  • /be-reachable status — report current state
  • /be-reachable stop — terminate the background heartbeat

The wrapper is idempotent: a second start while one is already running prints the existing agent_id and exits 0 without spawning a duplicate.

Step 1: Pre-flight — confirm wrapper is present

Run:

bash scripts/be-reachable.sh --help >/dev/null

If exit non-zero: stop. Print:

be-reachable: wrapper not found at scripts/be-reachable.sh.
Ensure you're in the TermLink project root (cd /opt/termlink).

Do NOT attempt to spawn listener-heartbeat.sh directly — the wrapper applies the right defaults and writes the state file that other tools rely on.

Step 2: Dispatch the subcommand

Map the user's argument to a subcommand:

User said Run
/be-reachable (no args) bash scripts/be-reachable.sh start
/be-reachable start ... bash scripts/be-reachable.sh start <args>
/be-reachable status bash scripts/be-reachable.sh status
/be-reachable stop bash scripts/be-reachable.sh stop

Pass through any extra arguments verbatim. The wrapper validates and errors with exit 2 if anything is malformed.

Step 3: Surface the result

After start, the wrapper prints a block like:

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.

be-reachable is a command published in the GitHub repository DimitriGeelen/agentic-engineering-framework (18 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,134 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
