vishal-gandhi 237e918f11 feat(integrations): add Devin for Terminal skills-based integration (#2364)
* feat(integrations): add Devin for Terminal skills-based integration

- Register DevinIntegration as a SkillsIntegration with .devin/skills/ layout
- Add catalog entry, docs row, and supported-agents listing
- Display /speckit-<command> hyphen syntax in init "Next Steps" panel
  (matches Claude/Cursor/Copilot skills mode, since Devin invokes skills
  by directory name)

Closes #2346

* fix(devin): implement -p non-interactive dispatch; clarify skills comment

Addresses Copilot review on PR #2364:

- Override build_exec_args() in DevinIntegration to emit
  'devin -p <prompt> [--model X]' for non-interactive text dispatch
  (verified Devin CLI supports -p / --print). Returns None when
  output_json=True since Devin has no structured-output flag, so
  CommandStep workflows that require JSON cleanly raise
  NotImplementedError instead of crashing on an unknown CLI flag.
  requires_cli=True is retained for tool detection.

- Extend the skills-integrations enumeration comment in
  specify_cli/__init__.py to include copilot and devin so the
  comment matches the code below it.

* fix(devin): always return exec args; document plain-text stdout

Addresses third Copilot review comment on PR #2364.

Returning None from build_exec_args() when output_json=True
incorrectly used the codebase's IDE-only sentinel: workflow
CommandStep checks 'impl.build_exec_args("test") is None' to
detect non-dispatchable integrations (test_workflows.py exercises
this with WindsurfIntegration). The previous implementation made
Devin appear non-dispatchable to all command steps even though it
runs fine via 'devin -p'.

Always return the args list. When output_json is requested, Devin
is still dispatched and returns plain-text stdout instead of
structured JSON; the docstring documents this explicitly.

* docs(devin): include claude in skills-integrations enumeration comment

Addresses Copilot review on PR #2364: the comment listing skills
integrations omitted Claude, which is also a SkillsIntegration
subclass. Updated to keep the comment accurate for future readers.

* test(devin): add build_exec_args regression tests; bump catalog updated_at

Addresses Copilot review on PR #2364, per @mnriem's request to
'address the Copilot feedback, especially the testing ask':

- tests/integrations/test_integration_devin.py: add TestDevinBuildExecArgs
  with three regression assertions:
    * build_exec_args returns args (not the None IDE-only sentinel)
    * --output-format is never emitted, regardless of output_json
    * --model flag is passed through correctly
- integrations/catalog.json: bump top-level updated_at to reflect the
  Devin entry addition so downstream catalog consumers can detect the
  change reliably.

# Supported AI Coding Agent Integrations
The Specify CLI supports a wide range of AI coding agents. When you run `specify init`, the CLI sets up the appropriate command files, context rules, and directory structures for your chosen AI coding agent — so you can start using Spec-Driven Development immediately, regardless of which tool you prefer.
## Supported AI Coding Agents
| Agent | Key | Notes |
| ------------------------------------------------------------------------------------ | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| [Amp](https://ampcode.com/) | `amp` | |

| Generic | `generic` | Bring your own agent — use `--integration generic --integration-options="--commands-dir <path>"` for AI coding agents not listed above |
## List Available Integrations
```bash
specify integration list
```
Shows all available integrations, which one is currently installed, and whether each requires a CLI tool or is IDE-based.
## Install an Integration
```bash
specify integration install <key>
```
| Option | Description |
| ------------------------ | ------------------------------------------------------------------------ |
| `--script sh\|ps` | Script type: `sh` (bash/zsh) or `ps` (PowerShell) |
| `--integration-options` | Integration-specific options (e.g. `--integration-options="--commands-dir .myagent/cmds"`) |
Installs the specified integration into the current project. Fails if another integration is already installed — use `switch` instead. If the installation fails partway through, it automatically rolls back to a clean state.
> **Note:** All integration management commands require a project already initialized with `specify init`. To start a new project with a specific agent, use `specify init <project> --integration <key>` instead.
## Uninstall an Integration
```bash
specify integration uninstall [<key>]
```
| Option | Description |
| --------- | --------------------------------------------------- |
| `--force` | Remove files even if they have been modified |
Uninstalls the current integration (or the specified one). Spec Kit tracks every file created during install along with a SHA-256 hash of the original content:
- **Unmodified files** are removed automatically.
- **Modified files** (where you've made manual edits) are preserved so your customizations are not lost.
- Use `--force` to remove all integration files regardless of modifications.
## Switch to a Different Integration
```bash
specify integration switch <key>
```
| Option | Description |
| ------------------------ | ------------------------------------------------------------------------ |
| `--script sh\|ps` | Script type: `sh` (bash/zsh) or `ps` (PowerShell) |
| `--force` | Force removal of modified files during uninstall |
| `--integration-options` | Options for the target integration |
Equivalent to running `uninstall` followed by `install` in a single step.
## Upgrade an Integration
```bash
specify integration upgrade [<key>]
```
| Option | Description |
| ------------------------ | ------------------------------------------------------------------------ |
| `--force` | Overwrite files even if they have been modified |
| `--script sh\|ps` | Script type: `sh` (bash/zsh) or `ps` (PowerShell) |
| `--integration-options` | Options for the integration |
Reinstalls the current integration with updated templates and commands (e.g., after upgrading Spec Kit). Defaults to the currently installed integration; if a key is provided, it must match the installed one — otherwise the command fails and suggests using `switch` instead. Detects locally modified files and blocks the upgrade unless `--force` is used. Stale files from the previous install that are no longer needed are removed automatically.
## Integration-Specific Options
Some integrations accept additional options via `--integration-options`:
| Integration | Option | Description |
| ----------- | ------------------- | -------------------------------------------------------------- |
| `generic` | `--commands-dir` | Required. Directory for command files |
| `kimi` | `--migrate-legacy` | Migrate legacy dotted skill directories to hyphenated format |
Example:
```bash
specify integration install generic --integration-options="--commands-dir .myagent/cmds"
```
## FAQ
### Can I use multiple integrations at the same time?
No. Only one AI coding agent integration can be installed per project. Use `specify integration switch <key>` to change to a different AI coding agent.
### What happens to my changes when I uninstall or switch?
Files you've modified are preserved automatically. Only unmodified files (matching their original SHA-256 hash) are removed. Use `--force` to override this.
### How do I know which key to use?
Run `specify integration list` to see all available integrations with their keys, or check the [Supported AI Coding Agents](#supported-ai-coding-agents) table above.
### Do I need the AI coding agent installed to use an integration?
CLI-based integrations (like Claude Code, Gemini CLI) require the tool to be installed. IDE-based integrations (like Windsurf, Cursor) work through the IDE itself. Some agents like GitHub Copilot support both IDE and CLI usage. `specify integration list` shows which type each integration is.
### When should I use `upgrade` vs `switch`?
Use `upgrade` when you've upgraded Spec Kit and want to refresh the same integration's templates. Use `switch` when you want to change to a different AI coding agent.
