tools-paced-send

Works a named list one item at a time on a fixed cadence: reads targets from a CSV column given as an argument, refuses an ambiguous column rather than guessing, paces sends so consecutive items are at least the interval apart, and never sends an item twice across restarts.

What it is for

tools-paced-send — work a named list one letter at a time, on a fixed cadence.

Sprint 4.56. The list, the template, the column, the interval and the sending account all arrive as arguments: nothing about the client's work is known here.

Two subcommands, and the split between them is the safety property. plan reads and renders and sends nothing, so a wrong column or a broken template costs nothing to find. send does the same work and then delivers, paced, recording each attempt before moving on.

Capabilities

No public items.

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

No public items.

No pub use re-exports: every item above is declared in this crate.

Boundary

Reaches into infrastructure.

Shares tier tools with 84 other crates: tools-advisory-reach, tools-archive-guard, tools-artifact-scaffold, tools-ask-ai-core, tools-ask-ais, tools-ask-gemini, tools-book, tools-book-report, … (84 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

No workspace crate depends on this one.
