register

register is a command for coding agents from HoussemDjeghri/bridger. It costs 10 tokens per session (334 once invoked), scanned A, original, MIT.

A command that registers the current project as a named peer so other coding-agent sessions can send it messages.

In plain words
What is it for?
Use it to register the project, start a persistent message watcher, and let other sessions address this session by its registered name.
Why use it?
It creates a known address for cross-session communication, while the watcher allows incoming messages to be received.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

register 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 5d 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.

What it actually says

Register the current project as a bridger peer so other Claude Code sessions can message it.

Run:

"${CLAUDE_PLUGIN_ROOT}/bin/bridger" register $ARGUMENTS

If no name was given, derive a short lowercase one from the directory name (letters, digits, single dashes) and use it. Report the registered name back to the user — they will type it in the other session to address this one.

IMPORTANT — registering is only half of it. A registered session can be addressed and can send, but it cannot receive until a watcher is running: registering does not start one, and nothing else reaches this session once it goes idle. Skipping this step is the difference between joining a channel and joining it muted.

So immediately after registering, before anything else, arm the watch:

"${CLAUDE_PLUGIN_ROOT}/bin/bridger" wait --follow

Run it as a persistent background task (Monitor tool if available, otherwise a background Bash task) and leave it running for the rest of the session — never in the foreground, which would block. Each line it emits is one incoming message #<seq> <from> <type>: <body>; answer an ask from your own context with "${CLAUDE_PLUGIN_ROOT}/bin/bridger" send <from> answer "<text>" --ref <seq>.

Confirm to the user that the watch is armed, not just that the name is registered.

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.
