thread

A command-line tool for viewing all messages exchanged with a specific contact.

In plain words
What is it for?
Use it to review a contact’s message history, such as messages from a certain date or the latest 100 messages.
Why use it?
It avoids opening a messaging app and searching through a conversation manually. You can limit the results by date or number of messages.

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.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 223 The whole file, excluding the scripts and references it only reads on demand.

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

thread 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 yesterday.

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.

Instructions

  1. Check if messages CLI is installed - if which messages fails, install it:
npm install -g @cardmagic/messages
  1. Run the command:
messages thread "$ARGUMENTS"

Options

  • --after YYYY-MM-DD - Only messages after this date
  • --limit N - Maximum number of messages (default: 50)

Examples

User: /messages:thread "John Smith" --after 2024-12-01 -> messages thread "John Smith" --after 2024-12-01

User: /messages:thread Boss --limit 100 -> messages thread "Boss" --limit 100

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.
