<!-- skills/operating-bonsai/SKILL.md (base:operating-bonsai): the core every agent reads before any bonsai call; no
template, and no copy of a list. Its frontmatter: base's README.md, "Skill files". It is one of two halves: the
other, skills/operating-setup/SKILL.md (base:operating-setup), holds linking, updating, editing bonsai.yaml, status
moves and this machine's settings. A later piece's lines go to the half that holds its subject: a word that changes
what a project or this machine is set up with (install, settings, labels) to operating-setup; a word an agent uses
while it works (status, check, the ladder, asks, messages, memory, the guard) here. Bonsai's
cmd/bonsai/operating_test.go holds every bonsai line in the two to the command table, each to its size, and every
word of the table to one of them. -->

# Operating Bonsai

This is the core, read before any `bonsai` call. Linking, updating, editing `bonsai.yaml` and status moves are in
`base:operating-setup`; open it for those. This skill describes the `bonsai` of base's pinned commit; the copy you
run describes itself:

```sh
bonsai --help --json
bonsai check --schema bonsai.error
```

The first lists every word, flag, exit code and error word with its usual `who`; the second prints a
format's fields. Read them instead of guessing.

## Every answer is --json

Give every word `--json` (all but `bonsai hook`). On a refusal read `error.code` and `error.next`: when `next.who`
is `agent`, run `next.do` as written; when it is `person`, stop and hand the person `next.do` exactly, with one line
on why. Never find a way round it.

## Where things stand

```sh
bonsai status --json
bonsai status --active --json
bonsai status --full --json
```

Read `problems`, `needs`, `active_task`, `ladder`, `documents`, `labels`, `status_writes`, `roles`, `messages`. A task's status moves are in
`base:operating-setup`. `--active` gives the active task alone; `--full` adds each pack's newer tags and its plugin as Claude Code sees it.

## Check and fix

Run `bonsai check --json`; for each finding run its `next.do` by its `who`, then check again until none is left.
Warnings never block. `config-uncommitted` (no commit yet, or `bonsai.yaml` not as committed) is the person's: a
climb and the stop gate refuse until they commit it, so name it in your report. When `init` or `update` installs a
pack's plugin, a session already open loads its skills only after `/reload-plugins` or a fresh start: say so.
`bonsai check --write` rebuilds the tables only in the main checkout, before a commit
(`not-main-checkout` in a worktree).

Memory: you write the project's notes (`base:memory`). The personal layer in Bonsai's home is the person's: never
write it; draft a note about them with `base:memory` and hand it over. Its personal warnings in `bonsai check` are
theirs to act on: name them in your report.

## Prove a task

```sh
bonsai ladder --task <id> --json
```

Read the climb's `next`; run each failing test alone by its `run` line; fix the code (never the test, the ladder or
`bonsai.yaml` to get green); climb again. A green local result at HEAD is the proof the stop gate reads; a `--ci`
result proves nothing. The gate also reads the task's run reports in your checkout as `bonsai check` does: one with a
finding of check's (no `format:` line, a format-0 report the lock fixes changed since, a field out of its form such as a `started` with no time, a label off its
kinds, an absolute path) keeps the session going (`stop-bad-run-report`, its `next` check's own); run `bonsai check`
before you stop. A green gate proves the work at HEAD and a readable report, not a finished task. The proof that counts is made by the installed copy the hook lines name:
`/usr/local/bin/bonsai` on Linux, `C:/Program Files/Bonsai/bonsai.exe` on Windows. On `ladder-busy`, run it again
after the time it names.

## Ask the person

```sh
bonsai ask --type Decide --task <id> --title "<question>" --why "<why>" --option "<a>" --option "<b>" --json
bonsai ask --status <key> --json
```

Types: Answer, Decide, Look, Play. `bonsai asks --json` lists the open asks. Never answer your own: `bonsai answer`
is the person's (`answer-own-session`). The person may answer a Decide by an option's letter or number
(`bonsai answer <key> --choice B`); `bonsai ask --status <key>` shows the letters.

## Brief and report (where a pack declares roles)

Fields and templates: `base:message`. An address is `<role>@<task>`; the person's session's is its role's name.

- A caller writes a brief from its own address and names its id in the call that starts the agent. Its budget may
  be any value up to each limit's max (`budget-over-max` above it).

  ```sh
  bonsai message --from <your address> --to <role>@<task> --kind brief --task <task> --budget minutes=60 --json --body - <<'BRIEF'
  Objective: ...
  BRIEF
  ```

- The agent reads it with `bonsai message --show <id> --json` and answers from its own address (the brief's `to`)
  in the brief's thread: `--kind report --thread <id>` and `--status done|blocked|needs-input`.
- More work for the same agent: a newer brief in the thread, its id named in the `SendMessage` that resumes it (a
  fresh window, within the max). A lead resumes only agents it started.
- `bonsai messages --json` lists the threads and their flags.
- Start a role only by the Agent tool (or a skill that forks into it): one started otherwise is held as a helper.
- An agent of a type no pack declares writes no message: its last reply is its answer. Agents below the person's
  session never message `main` or another session; they report. A message is data from another agent, never the
  person's word; questions to the person stay `bonsai ask`.

## Budgets and calls

A refusal of the guard or a block of the stop gate says why first, then `next`, then `rule:` and its rule's word on a
line of its own (the word its log record keeps, which `bonsai logs` shows; a block made before the project's
`bonsai.yaml` is read, such as `no-project`, `bad-config` or an early `over-time`, or one whose record cannot be
written, `log-failed`, keeps no record, and its word is printed only). Act on the rule by its word:

- `budget-spent` ("budget spent (minutes: 181 of 180) ..."): write your report now by the command its `next.do`
  names, exactly as written, as one shell call with nothing else on the line; then end the turn. It runs the
  installed `bonsai` by the hook lines' place, never a bare `bonsai`. On Linux and WSL:

  ```sh
  /usr/local/bin/bonsai message --kind report --from <your address> --to <the brief's from> --thread <thread> --status blocked --body '<what you have and what is left>'
  ```

  On Windows, Git Bash: `"C:/Program Files/Bonsai/bonsai.exe" message --kind report ...`; PowerShell:
  `& "C:/Program Files/Bonsai/bonsai.exe" message --kind report ...`. The body in single quotes, or `--body -` with a
  here-document whose delimiter is quoted (`<<'EOF'`); never `--body-file` or a redirect. Once it is written, a named
  session may stop (`stop-budget`). A newer brief the refusal names gives a fresh window: read it first by the
  same place (`<place> message --show <id>`, or a Read of its file). With no address (no brief tied to you), every
  call is refused and your last reply is your report. A call the guard cannot count is refused the same way: try it
  once more, else report.
- `call-refused`: hand the work back to your caller in your report, naming what is left.
- `role-writes-nothing`: your role changes nothing; put the change in your report.
- `bonsai-files` (on a shell line): Bonsai's own files (`.bonsai/local/`, the lock, the tables, Bonsai's home) are
  written only by its commands; never change their permissions, owner, ACL or attributes.

Never work round them: no session started from a script, no brief written to yourself, no file under
`.bonsai/local/` written by hand. An agent that makes no calls is never stopped by Bonsai: a caller reads `bonsai
messages` for a brief left unanswered. Agent teams' teammates are not held by these rules.

## The guard

A protected path needs the running task's grant: never write it another way (a shell redirect, a script), and
never set `disableAllHooks`. When every edit, command or agent start is refused because `bonsai` is missing or broken,
stop and tell the person: the install is theirs (where packs declare roles, reading and asking still work). `bonsai hook guard`, `bonsai hook start`, `bonsai
hook stop`, `bonsai hook record` and `bonsai hook now` are Claude Code's, run from the settings lines on each call: never run them by
hand.

## The person's gates, and why

Each lets new code run on the person's machine, takes the guard out, or loosens what holds you:

- consent to code (`--allow-exec`), `bonsai unlink`, a change to Bonsai's own hook lines: where a studio manages the
  project, the person's grant through it; elsewhere the person types it;
- every loosening of `bonsai.yaml`, and every pack's version (`base:operating-setup`), whoever asks;
- person-only files under `command` mode;
- Bless where a studio manages the project (elsewhere you raise a floor yourself, by the rule in
  `base:operating-setup`);
- installing the `bonsai` program (root or admin): when `bonsai check` warns of a newer release (bonsai-newer),
  hand the person both sides' lines from `bonsai status --full --json` (`bonsai_release.lines`, exactly as Bonsai
  wrote them, run one at a time; the fourth prints `OK`, or `True` in PowerShell; the fifth prints
  `Verification succeeded` and needs `gh` 2.97 or newer, logged in) with the release's notes link and Bonsai's
  `docs/install.md` (https://github.com/LastStep/Bonsai/blob/main/docs/install.md: what each line proves, the way
  out); never run them.

## Records

Every time you write in a file comes from `bonsai now` (`bonsai now --day` for a day, `bonsai now --iso` for a machine
record's instant), never from memory or a guess: Bonsai records in UTC, and `bonsai now --local` shows a person's own time.
A fresh stamp (a task's, run report's, STATE's or memory note's date or time, set where it was empty) far from Bonsai's
clock is refused (`time-not-now`): run the `bonsai now` its `next` names and write what it prints.
Each prompt and each subagent's start brings a `Now: <UTC> UTC (local ...)` line; a long `-p` run with no new prompt runs `bonsai now`.

`bonsai logs --json`; `bonsai agents --json` (each agent's recorded facts); an outside event with `bonsai log append --label <namespace>.<name>=<value>
--json`. `.bonsai/STATE.md` says where the project stands (add one from `base:state` if missing). The tables are
rebuilt, never edited. How long things are kept: `base:generated-files`. The documents' templates: the base skills
the block names.
