## Description

Amend a published CLI from one of two input sources: (1) dogfood mode mines the active Claude Code session transcript for friction (missing flags, hand- rolled API payloads, silent-null returns); (2) direct-input mode accepts user-supplied asks (rename a command, add commands or feeds, fix a named bug, optionally sniff the source site for new endpoints). Confirms scope with the user, plans + executes the fix autonomously, scrubs PII, and opens a PR against mvanhorn/printing-press-library. Two user-in-loop checkpoints: scope after capture, PR draft before open. Trigger phrases: "amend the CLI", "submit a patch", "fix what I just dogfooded", "open a PR for this CLI", "patch this CLI", "add features to my CLI", "rename this command", "add these feeds to <cli>", "sniff for new APIs in <cli>", "amend with these ideas", "use printing-press-amend", "run printing-press-amend".

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# /printing-press-amend

Turn a dogfood session into a PR for a printed CLI in the public library.

```bash
/printing-press-amend                 # auto-detect target CLI from session
/printing-press-amend superhuman      # explicit short name
/printing-press-amend superhuman-pp-cli
/printing-press-amend "$PRESS_LIBRARY/superhuman"
```

This skill lives in this repo (the machine) and acts on a printed CLI in the public library. It is sibling to `/printing-press-publish` (adds a new CLI), `/printing-press-polish` (improves a CLI pre-publish), and `/printing-press-retro` (reflects on the machine itself). None of those cover post-publish CLI amendments driven by real-session friction.

The artifact this skill produces is semantically a "patch" (in the git/PR sense), tracked by the public library's `.printing-press-patches/` directory (one file per patch). Inline `// PATCH(...)` source comments are optional navigation aids when they make a customized site easier to grep. The slash-skill name is `amend` to disambiguate from the existing `cli-printing-press patch` binary subcommand (which AST-injects pre-defined features, different mechanism, different intent).

## Setup

Before doing anything else:

<!-- PRESS_SETUP_CONTRACT_START -->
```bash
# min-binary-version: 4.0.0

# Derive scope first, needed for local build detection
_scope_dir="$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")"
_scope_dir="$(cd "$_scope_dir" && pwd -P)"
