arm-inbox

arm-inbox is a command for Claude Code from shaharsha/claude-skills. It costs 23 tokens per session (260 once invoked), scanned A, original, MIT.

A retired setup command for cross-session messaging between coding-agent sessions.

In plain words
What is it for?
Nothing new—it only documents that the former arming and setup process has been removed.
Why use it?
It is no longer needed because messaging is enabled automatically in supported versions; older versions do not provide the messaging channel.

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

arm-inbox 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 11d 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

Retired. There is nothing to arm.

ccarm, ccsend --self and the FRESH LEASE check are gone. Cross-session messaging is on for every session ≥ v2.1.224 with nothing to enable. Below that version a session binds no socket, appears in no listing, and looks normal from the inside.

Where the content that used to live here now lives — one copy each, deliberately:

addressing · TITLE vs NAME · ccpeers      /dispatch §1   ·  /worker §1
channel failure modes (HELD/CAPPED/…)     /dispatch "The channel is better…"
what carries what, RECORD vs MESSAGE      LANE-PREAMBLE.md §8
who is stuck                              ccstatus — messaging never answered this

⚠️ Do not re-add that material here. This file was a third copy of rules that already had homes, and a rule written in two places for two readers is a disagreement waiting to be found by whoever is caught between them. Delete this file rather than growing it.

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.
