send

send is a command for coding agents from tinhtran24/maestro. It costs 0 tokens per session (170 once invoked), scanned A, a copy of send, Apache-2.0.

A command for sending a message to an agent session that is currently running. An agent session is a live task being handled by a coding assistant.

In plain words
What is it for?
Use it to add instructions, narrow the task, correct the assistant's focus, or point it to the right file or code location.
Why use it?
It lets you correct or redirect the assistant while it works, without stopping and starting a new session.

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

send 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 3d 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.

Origin

This is a copy

92% identical to send — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

to send

Send a message to a running agent session. Use this to correct or direct a live agent mid-stream without killing and respawning it.

Syntax

maestro send [flags]

Flags

Flag Meaning Default / Required
--message string Message body Required
--session string Session id Required

Examples

# Send a correction to a running session
maestro send --session mer-3 --message "Focus only on the backend; ignore frontend files."
# Give the agent new instructions mid-task
maestro send --session mer-3 --message "The issue is in session_manager.go line 142, not in the CLI. Investigate there."
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.
