Pascal THUET 490566847c feat(cli): honor SPECIFY_INIT_DIR in the specify CLI project resolver (#3186)
* feat(cli): honor SPECIFY_INIT_DIR in the specify CLI project resolver

The shell resolver honors SPECIFY_INIT_DIR (#2892), but the Python CLI did
not: it resolved the project as Path.cwd() + a .specify/ check and never read
the override. So setup-plan.sh respected it while `specify integration install`
ignored it, and you still had to cd into the member project.

Route project resolution through a shared _resolve_init_dir_override() that
applies the shell resolver's validation rules (relative to cwd, must exist and
contain .specify/, hard error, no fallback, same error strings). It's wired into
_require_specify_project() — the chokepoint for every project-scoped subcommand
(integration/extension/workflow/preset/...) — and the `workflow run <file>`
standalone path, which re-applies its symlinked-.specify guard on the override
branch too. init is unchanged: it creates .specify/, so the must-pre-exist rule
doesn't apply.

The resolver canonicalizes symlinks via Path.resolve() while the shell keeps the
logical path; they agree for non-symlinked paths (documented in the resolver).

Tests in tests/test_init_dir_cli.py mirror the strict cases from test_init_dir.py
through the CLI; conftest now strips SPECIFY_* for the whole suite so a stray
export can't perturb the now-env-reading resolver. Docs note the CLI applies the
same rules.

Discussion: github/spec-kit#2834

(Disclosure: I used an AI coding agent to audit the call sites and resolver,
draft the change, and run an adversarial code review; reviewed by me.)

* fix(cli): honor SPECIFY_INIT_DIR for bundle commands

* fix(bundler): refuse symlinked .specify on the SPECIFY_INIT_DIR override path

find_project_root refuses a symlinked .specify (following it could read/write
outside the tree, and a test pins that), but the SPECIFY_INIT_DIR override added
for bundle commands returned early and skipped that guard:
_resolve_init_dir_override validates .specify with is_dir(), which follows
symlinks. So `specify bundle` accepted via the override a layout the cwd path
rejects. Re-check the override result with the same guard, plus a regression test.

(Disclosure: found via an AI code review and fixed with an AI coding agent;
reviewed by me.)

* fix(cli): keep SPECIFY_INIT_DIR strict for bundles

Treat an explicit symlinked SPECIFY_INIT_DIR project as a hard bundle error instead of returning no project, which could initialize the current directory. Align the docs with the actual unset resolver behavior.

Assisted-by: Codex (model: GPT-5, autonomous)

* docs(core): note symlinked .specify handling differs across CLI surfaces

A symlinked .specify is followed by integration/extension/workflow (matching the
shell resolver) but refused by bundle and workflow run <file> (write
confinement). Document the asymmetry so it reads as intentional.

(Disclosure: AI-assisted; reviewed by me.)

* docs(core): reframe symlinked .specify note around the override invariant

Per maintainer feedback on #3186: SPECIFY_INIT_DIR relocates where the project
is, not how a surface treats symlinks. Each surface keeps its cwd-path stance
(write surfaces refuse a symlinked .specify, read/config surfaces follow it),
so the split is one policy relocated, not an inconsistency.

* docs: address Copilot review on resolver docstrings

- _project.py: the error messages "mirror" the shell wording rather than
  "match" it (the CLI renders a Rich `Error:` line, the shell a plain `ERROR:`).
- find_project_root: document that honoring SPECIFY_INIT_DIR when start is None
  can raise typer.Exit / BundlerError, so the Path | None signature isn't
  surprising to direct callers.

* docs(bundler): note require_project_root inherits the override raise behavior

find_project_root can raise typer.Exit / BundlerError under the SPECIFY_INIT_DIR
override (start=None); require_project_root inherits that, so document it
alongside its own BundlerError-on-missing-project.

* docs: clarify symlinked project root behavior

# Using Spec Kit in a Monorepo
A Spec Kit project is **directory-scoped**: the project is whichever directory
contains `.specify/`. A monorepo can hold several independent Spec Kit projects
under one repository root, each with its own `.specify/`, `specs/`, constitution,
and feature numbering.
Root resolution already prefers the **nearest** `.specify/` over the Git
toplevel, so commands run from inside a member project resolve to that project,
not the repo root.
## Layout
```text
my-monorepo/
├── .git/ # one Git repository at the root
├── apps/
│ ├── web/
│ │ └── .specify/ # Spec Kit project "web"
│ │ └── memory/constitution.md
│ └── api/
│ └── .specify/ # Spec Kit project "api"
│ └── memory/constitution.md
└── packages/
└── ui/
└── .specify/ # Spec Kit project "ui"
```
Initialize each member project independently:
```bash
specify init apps/web --integration claude
specify init apps/api --integration claude
```
Each project keeps its own `specs/` directory and numbers features
independently (`apps/web/specs/001-…`, `apps/api/specs/001-…`).
## Working inside a member project
The default workflow is unchanged: change into the project directory and run the
slash commands. Root resolution finds the nearest `.specify/`.
```bash
cd apps/web
# then run /speckit.specify, /speckit.plan, … in your agent
```
## Targeting a member project from the repo root
For non-interactive or CI runs where you do not want to `cd`, set
**`SPECIFY_INIT_DIR`** to the member project root (the directory *containing*
`.specify/`). Relative paths resolve against the current directory.
```bash
# operate on apps/web from the monorepo root (no cd required)
export SPECIFY_INIT_DIR=apps/web
```
The path must exist and contain `.specify/`. If it does not, the command
**errors and does not fall back** to the current directory or the Git toplevel.
This is deliberate: a typo never writes specs into the wrong project. A
nonexistent path is reported as you typed it; a path that exists but is not a
Spec Kit project is reported as its resolved absolute path:
```text
# SPECIFY_INIT_DIR=apps/wbe (typo: no such directory)
ERROR: SPECIFY_INIT_DIR does not point to an existing directory: apps/wbe
# SPECIFY_INIT_DIR=apps (exists, but has no .specify/ of its own)
ERROR: SPECIFY_INIT_DIR is not a Spec Kit project (no .specify/ directory): /home/you/my-monorepo/apps
```
`SPECIFY_INIT_DIR` selects the **project**; `SPECIFY_FEATURE_DIRECTORY` selects
the **feature** within it. They compose: set both to pick a project and a
feature non-interactively. See the
[`SPECIFY_INIT_DIR` reference](../reference/core.md#environment-variables) for
the full contract and the two-axes model.
The `specify` CLI's project-scoped subcommands honor the same variable, so they
target a member project from the root without `cd` too:
```bash
export SPECIFY_INIT_DIR=apps/web
specify workflow list # lists apps/web's workflows
specify integration status # reports apps/web's integration
```
The validation rules are the same: the path must exist and contain `.specify/`,
with no fallback to the current directory.
## How `SPECIFY_INIT_DIR` reaches your agent
`SPECIFY_INIT_DIR` is read by the shell scripts that the slash commands invoke
(`get_repo_root` in Bash, `Get-RepoRoot` in PowerShell). It takes effect only
when it is present in the environment of the shell that runs those scripts.
- **Scripted / CI runs:** export it in the same shell that drives the commands;
it is reliable there.
- **Interactive agents:** whether an exported variable reaches the shell tool an
agent uses is agent-specific. Export `SPECIFY_INIT_DIR` *before* launching the
agent, and verify once (e.g. run `/speckit.specify` and confirm the new feature
landed under the intended project's `specs/`).
## Git in a monorepo
> [!NOTE]
> Spec Kit project files are scoped to the **resolved project root**, but Git
> operations still run in the containing Git work tree. In a monorepo with a
> single Git repository at the root and projects in subdirectories, feature
> branch creation creates or switches branches in the shared root repository.
> Spec directories still live under the selected member project, while the Git
> branch namespace is shared by the whole monorepo. Manage branches and commits
> at the repository root, or initialize Git per member project if you want
> isolated per-project branch namespaces.
## Constitutions
Each member project has its own `.specify/memory/constitution.md` and
`/speckit.constitution` edits the local project's file. Spec Kit does not provide
a built-in base/inheritance mechanism; if you want one constitution to reference
shared rules elsewhere in the monorepo, you need to maintain that wiring yourself.
Otherwise, duplicate or sync shared engineering rules per project.
