# Conventions

The skills plugin used to read a per-project `dev-cycle-profile.yml`.
It no longer does. There was never a parser — the profile was prose
the skill bodies told the model to read, and almost every slot was
either dead, constant across all projects, or derivable. So the
plugin now splits cleanly in two:

- **Fixed conventions** (this file) — the things that were constant
  across every project. They are not configurable; the skill and agent
  bodies name them directly.
- **Per-project facts** — the handful of things that genuinely vary
  per project (where the code lives, how to build and test it, the
  tracker slug, …). These live as prose in each project's own
  `CLAUDE.md` under a `## Skills plugin: project facts` heading. See
  `../templates/CLAUDE.md.fragment` for the template, and the section
  list at the bottom of this file.

## File layout

| Artefact | Location |
|----------|----------|
| Specs (from `specify`) | `docs/specs/` |
| Plans (from `planner`) | `docs/plans/` |

These directories are fixed. A project that keeps specs and plans
elsewhere is the rare exception and states the override in its
`CLAUDE.md` project facts.

Both directories are **git-ignored** — their contents are transient
working files, never committed (see § Lifecycle). The ignore is
**project-local**: each project commits a `docs/.gitignore` whose two
entries, `specs/` and `plans/`, are relative to `docs/` and so match
`docs/specs/` and `docs/plans/`. That `docs/.gitignore` is the one
committed thing — it travels with the repo; the spec and plan files it
covers never are. It is created once (whichever skill first writes a
working file — `specify`, or `planner` on a direct tidy dispatch —
creates it if absent) and committed like any other repo file, after
which both directories are invisible to git for every future cycle. A
new project sets this up as part of adopting the plugin
(`../templates/CLAUDE.md.fragment`).

## Lifecycle

`docs/specs/` and `docs/plans/` hold **only the active cycle's
artefacts** — they are working space, not an archive. A spec or plan is
valid for the cycle that produces it; its code shapes drift the moment
the code moves, so a stale one left lying around reads as a live API
reference and misleads the next agent that opens it.

The two directories are **git-ignored** — their contents are never
committed. A spec/plan is a working file: present on disk while its
cycle is live (readable across sessions, since the working tree
persists), and at **cycle close** — after `audit` is drift-clean — the
orchestrator **discards** it with a plain shell `rm`. There is nothing
to `git rm` (it was never tracked) and no deletion commit is produced;
the working tree is simply left without a stale artefact. This is the
same shell-delete-an-uncommitted-file mechanic `specify` already uses on
its grounding-`BLOCK` failure path.

A spec/plan is therefore **transient on disk**: present for its own
cycle, `rm`'d afterwards, and — never having been committed — leaving no
trace in git. It is **not recoverable, by design**. The durable record
of a past cycle's design intent is the **design ledger only** (where the
rationale is lifted during audit); the implementation is committed as
normal code.

**No durable artefact may cite a spec or plan** — not by number, not by
path. Code, tests, docs, and ledger entries outlive the spec/plan that
prompted them, so any reference to `docs/specs/…` or "spec NNNN" would
dangle the moment the cycle closes. Cite the **design-ledger contract**
instead (e.g. a `C`-id); it is the durable record the spec's rationale
was lifted into.

## Naming

Files are named `slug.md` — a short kebab-case identifier of the
cycle's topic (slug separator `-`). There is **no numeric prefix**:
because the directories are git-ignored, shell-`rm`'d at cycle close,
and cited by nothing (see § Lifecycle), they hold at most the active
cycle's handful of files, so a slug is already unique enough — the old
scan-for-the-next-free-number ritual bought nothing and is gone. A
`fieldtest`-produced spec takes a `fieldtest-` prefix
(`fieldtest-slug.md`) so it is recognisable in the working tree as the
next cycle's planning input rather than this cycle's own spec — it is
written after audit's cycle-close sweep and discarded by the next
cycle's sweep (see `../fieldtest/SKILL.md`).

**The file name is not the cycle number.** The **cycle number** that
appears in commit subjects (`feat(NNNN)`, `audit(NNNN)`) and in `git
log` cycle ranges is a distinct, monotonic identifier that must survive
spec/plan discard. Source it from the highest `NNNN` in the
`feat(NNNN)` / `audit(NNNN)` git-log subjects, plus one — never from a
file name (there is none) and never from a per-directory scan. Cycle
commits therefore MUST carry the zero-padded `(NNNN)` cycle number in
their subject.

## Vocabulary

The pipeline's nouns are fixed:

| Term | Meaning |
|------|---------|
| **cycle** | One round in the pipeline graph (`brainstorm → specify → planner → implement → audit → [fieldtest]`). NOT the top-level container. |
| **iteration** | A sub-unit of a cycle. |
| **milestone** | Tracker container spanning many cycles; closes only when complete AND functional (see `pipeline.md` § Milestone-close gate). |
| **contract** | A single design-ledger entry. |

When a project declares a glossary (in its CLAUDE.md project facts),
that glossary is the source of truth for domain nomenclature and
overrides these names where they collide (see `glossary-convention.md`).

## Standing reading

Every agent reads, at the start of every dispatch:

- the project's `CLAUDE.md`
- `git log -10 --format=full`

A project may add more — globally or per role — in its CLAUDE.md
project facts (`standing reading`). If the project declares a
glossary, that file is implicitly standing reading for every role
too.

## Git discipline

- **Only the orchestrator commits.** No skill agent runs `git commit`.
  Agents write into the working tree as unstaged changes; the
  orchestrator inspects, decides commit shape, and commits.
- **main HEAD is sacrosanct — below the session anchor.** Nobody runs
  `git reset` / `git revert` on user-ratified main history (or any
  protected branch). main moves forward only via orchestrator commits; a
  wrong agent diff is discarded — by the orchestrator, between
  iterations — with `git checkout -- <paths>` / `git stash`, never by
  rewinding ratified history. That discard idiom is the orchestrator's
  alone: an agent running INSIDE a multi-task `implement` iteration
  never checkouts/restores a file — nothing commits between tasks, so
  it would silently destroy sibling tasks' uncommitted work; in-loop
  recovery is forward-editing or `BLOCKED` (`implement/SKILL.md` Iron
  Law, issue #23).
  **One narrow `/boss` exception — the rollback sandbox:** inside an
  autonomous run the orchestrator anchors on the HEAD it started
  from (the last user-ratified state; under the worktree bullet below
  that is the run branch's base, so a reset moves only the branch and
  can never reach `main`) and MAY `git reset --hard` its
  *own* commits *above* that anchor — autonomous, **unpushed** work only
  — back toward (never below) the anchor when it has run into a dead end.
  A pushed commit has left the sandbox and is forward-only (`git revert`).
  See `../boss/SKILL.md` § Direction freedom.
- **Substantive work runs in a git worktree — merge is human-in-the-loop.**
  Any substantive work stream targeting `main` — a feature, a bug fix, a
  refactor; anything beyond a trivial mechanical edit — is isolated into
  a git worktree on its own branch before work starts, in every mode:
  autonomous (`/boss`, see `../boss/SKILL.md` § The run worktree) and
  interactive alike. (Background sessions are worktree-isolated by the
  harness already; this convention extends the same isolation to the
  sessions the harness does not guard.) The worktree branches from the
  current **local** HEAD — pin `worktree.baseRef: "head"` in settings;
  the harness default `fresh` bases the branch on origin's tip, which
  is routinely stale under this convention's no-autonomous-push
  discipline. Name the branch after the
  tracker issue where one exists (`issue-N-<slug>`); a live worktree
  branch is then also the visible being-worked-on signal in
  `git worktree list`. The branch reaches `main` only through a
  **user-ratified merge**: the user reviews the result, then the
  orchestrator merges — fast-forward preferred (rebase the branch onto
  `main` first if `main` has moved) — pushes (the ratification covers
  the push), and removes the worktree and
  deletes the branch. No pull request is opened, and the merge is never
  autonomous. `closes #N` markers consequently fire at merge-and-push
  time, when the commits reach the default branch.
  **One exception:** the skills meta-repo itself forbids worktree
  development outright (its `CLAUDE.md`: the install symlinks resolve to
  the primary clone, so worktree edits are silently ineffective) and
  stays direct-on-`main`.

These also appear in the universal-discipline fragment
(`../templates/CLAUDE.md.fragment`) that each project's CLAUDE.md
imports.

## Issue tracker

The tracker is **Gitea** and the commit close-marker is `closes #N`
(`refs #N` for non-closing work). Work-start is signalled by
**assignee, not label**: the actor that begins work on an issue
assigns it to the agent tracker user (`claude`) — one write, no
removal; the assignee survives the close as provenance. There is no
`in-progress` label. The live worktree branch (`issue-N-<slug>`,
§ Git discipline) is the git-side counterpart. The per-project repo slug and the
list/show commands live in the project's CLAUDE.md project facts
(see below) — the `boss` skill reads the forward queue from there and
records its fork decisions on the run's reference issue there, and an
ad-hoc `spec-skeptic` `scope-fork` dispatch reads single issues with
their comment threads from there.

Separately, `/boss` files **skill-system deficiencies** — faults in the
plugin itself, hit mid-run — against the **plugin's own** tracker (slug
derived from the plugin checkout's git remote), provenance carried by a
body block and never a new label. The skills meta-repo is not driven
through its own pipeline, so this tracker and a project's tracker never
coincide. See `../boss/SKILL.md` § Skill-system feedback.

## Pipeline

The phase set, the gates, and the conditional dispatch are **fixed**
and documented once in `pipeline.md`. There is no per-project pipeline
configuration. In particular: `brainstorm`, `specify`, `planner`,
`implement`, `audit`, `debug`, `tdd`, `fieldtest`, and `docwriter` are
always available. `tdd` is a standard entry path for test-specifiable
work — not an opt-in. `audit` is mandatory at cycle close.
`fieldtest` / `docwriter` are orchestrator-dispatched. There is no
per-project behavioural toggle: spec auto-sign is always on under
`/boss`.

## Per-project facts (in each project's CLAUDE.md)

Under `## Skills plugin: project facts`, where applicable:

| Fact | Used by | Notes |
|------|---------|-------|
| **code roots** | architect, quality-reviewer, fieldtester | Directories reviewers walk. Required. |
| **build / test command** | implement, audit | Required. Exit 0 = success. |
| **lint command** | (quality) | Optional. |
| **doc-build command** | docwriter | Optional; prints warnings on stderr. |
| **regression scripts** | audit (bencher) | Optional list; non-zero exit = regress. |
| **architect sweeps** | audit (architect) | Optional list; non-zero exit = drift suspicion. |
| **design ledger** | architect, most agents | Optional path (e.g. `design/INDEX.md`). |
| **glossary** | every role | Optional path; implicitly standing reading. |
| **design contracts / models** | docwriter, specify | Optional dirs. Aspirational-source frontmatter marker recommended (see below). |
| **bench dir** | fieldtest, bencher | Optional path. |
| **public interface** | fieldtester | Optional list — the only surface the fieldtester may read; everything else (code roots, bench) is forbidden to it. |
| **fieldtest examples** | fieldtester | Optional path where fixtures are written. |
| **by-role standing reading** | named agent | Optional; extra files/commands a specific role reads. |
| **issue tracker** | boss, spec-skeptic | Repo slug + list command + show command (the latter MUST render an issue WITH its comments). |

### Aspirational-source marker (recommendation)

Files under a project's design-models / RFCs / proposals directory
commonly carry aspirational code — constructs written before the
surface that parses them exists. To let a later `specify` tell
aspirational content from validated contract, give each such file a
frontmatter marker:

```yaml
---
status: aspirational
validated-against: <commit-sha | "no validation">
---
```

When the marker is absent the signal is simply absent — `specify`
degrades to treating the content as unmarked, never hard-failing.
Content lifted from an aspirational source is flagged as a target,
not verified fact, before it ships in a spec.
