# CLAUDE.md

Working notes for AI agents in the Scout monorepo.

## This repo holds two shipping artifacts

| Path | Artifact | Read next |

|---|---|---|

| `plugin/` | The Scout Claude Code plugin + Python engine (`scoutctl`) | `plugin/CLAUDE.md` |

| `apps/macos/` | The Scout macOS menu-bar app (SwiftUI) | `apps/macos/CLAUDE.md` |

**Work in the subtree that owns the change, and read that subtree's `CLAUDE.md`

first.** The two have different languages, test runners, and release flows.

## Rules that span both subtrees

- **`.claude-plugin/marketplace.json` lives at the REPO ROOT**, not in `plugin/`.

`claude plugin marketplace add` reads it from there. `plugin.json` — the

canonical version — lives at `plugin/.claude-plugin/plugin.json`.

- **Everything the plugin needs at runtime must stay under `plugin/`.**

`CLAUDE_PLUGIN_ROOT` resolves to the materialized `plugin/` subtree only; a

plugin file that reaches outside it is broken for every installed user, and

nothing in this repo will tell you.

- **Tags are prefixed:** `plugin/vX.Y.Z`, `app/vX.Y.Z`. Never push a bare

- **Contract artifacts are generated, never hand-edited.** The connector roster

and schedule snapshot each have ONE canonical file under

`plugin/engine/scout/`, generated from its `.yaml`, and every client copy

under `apps/*/` is a byte copy of it. To change one, from `plugin/engine`:

edit `scout/connectors.yaml` (or `scout/defaults/schedule.yaml`), regenerate

the canonical file with

`.venv/bin/python -m scout.scripts.connectors_snapshot --no-also-write-app-fixture`

(or `schedule_snapshot`), then from the repo root `cp` it over every client

copy `contract.yml` checks. **Always pass

`--no-also-write-app-fixture`** — the default also writes into a sibling

`~/scout-app` checkout outside this repo, and never into `apps/`.

`contract.yml` fails the build if a copy drifts. See

`docs/superpowers/specs/2026-09-03-monorepo-consolidation-design.md` §7.

- **The parser corpus has one canonical copy too:**

`plugin/engine/tests/fixtures/contract/parser-corpus.json`. Edit it, set

`EXPECTED_SHA256` (`plugin/engine/tests/unit/test_parser_corpus_checksum.py`)

and `canonicalSHA256`

(`apps/macos/ScoutTests/ActionItems/ParserContractTests.swift`) to its new

`shasum -a 256`, then `cp` it to

`apps/macos/ScoutTests/Fixtures/parser-corpus.json` — all in one commit.

(scout-iOS-app vendors a copy in its own repo; see `apps/macos/CLAUDE.md`.)

- **Never edit a `*.snapshot.json` by hand.** That is what broke the shipped

connector roster for four months.

- **Plugin history was absorbed with `git subtree`, SHAs preserved.** `git blame

plugin/<file>` crosses the merge to the original commits, but `git log --

plugin/<file>` stops at the merge commit — for a plugin file's earlier

history run `git log <subtree-merge>^2 -- <path without the plugin/ prefix>`

(the first subtree merge is the commit titled "absorb scout-plugin into

plugin/").

## Cross-cutting changes

A change touching both subtrees (a new `scoutctl` subcommand the app calls, a

snapshot schema change) lands as ONE commit, and `contract.yml` is the gate.

That is the entire reason these repos were merged — do not split such a change

across two PRs out of habit.
