Retire/remove `iflow` (iFlow CLI) integration — product discontinued

[mnriem]

The `iFlow CLI` integration (`src/specify_cli/integrations/iflow/`) targets a product that has been shut down.

• iFlow announced it stopped maintenance on 2026-03-20 and officially closed on 2026-04-17 (UTC+8). The repo `iFlow-AI/iflow-cli` carried a shutdown banner and the team directed users to migrate elsewhere.
• `install_url` currently points to `https://docs.iflow.cn/en/cli/quickstart\`.

Suggested action: deprecate and remove the `iflow` integration (subpackage, registry entry in `integrations/init.py`, catalog entry, and `tests/integrations/test_integration_iflow.py`).

Bug Assessment: Retire/Remove iflow Integration — Product Discontinued

• Slug: retire-iflow-integration
• Created: 2026-06-25T21:46:00Z
• Source: issue Retire/remove iflow (iFlow CLI) integration — product discontinued #3166
• Verdict: valid
• Severity: medium

Report (summarized)

Reported by @mnriem. The iflow integration (src/specify_cli/integrations/iflow/) targets iFlow CLI, a product that was officially shut down — shutdown announced 2026-03-20, final closure 2026-04-17. The upstream repo (iFlow-AI/iflow-cli) carried a shutdown banner and directed users to migrate. The integration's install_url (`(docs.iflow.cn/redacted) is dead. Suggested action: remove the integration, its test file, registry entry, catalog entry, and related references.

Symptom

Users who run specify init --integration iflow receive a functioning file scaffold, but the underlying product no longer exists, the install URL is broken, and any user who follows it reaches a dead endpoint. The integration continues to appear in the CLI help, issue templates, and catalog as though it is a supported, active tool.

Reproduction

1. Clone spec-kit and run specify init my-project --integration iflow.
2. Observe that .iflow/commands/ is scaffolded successfully — no runtime error.
3. Follow the install_url (`(docs.iflow.cn/redacted) — page is unreachable (product shut down 2026-04-17).
4. Note that specify integration list and CLI help still present iflow as a valid option.

Suspected Code Paths

• src/specify_cli/integrations/iflow/__init__.py:1–23 — IflowIntegration class; install_url points to dead endpoint.
• src/specify_cli/integrations/__init__.py:67 — import of IflowIntegration in _register_builtins().
• src/specify_cli/integrations/__init__.py:106 — _register(IflowIntegration()) call.
• tests/integrations/test_integration_iflow.py:1–11 — dedicated integration test; must be removed with the integration.
• tests/test_agent_config_consistency.py:30 — "iflow" in the expected-agents list.
• tests/test_agent_config_consistency.py:295–315 — three iflow-specific consistency tests.
• tests/integrations/test_registry.py:26 — "iflow" in registry key list.
• integrations/catalog.json:267–275 — "iflow" catalog entry.
• docs/reference/integrations.md:25,192 — two documentation table rows referencing iflow.
• .github/ISSUE_TEMPLATE/bug_report.yml:81 — iFlow CLI option in agent dropdown.
• .github/ISSUE_TEMPLATE/feature_request.yml:75 — same.
• .github/ISSUE_TEMPLATE/agent_request.yml:11 — iFlow CLI listed among currently supported agents.

Root Cause Hypothesis

The iFlow CLI product was shut down in early 2026 after the integration was added in spec-kit v0.3.2 (PR #1875, March 2026 newsletter). No automated check exists to detect when an upstream CLI product goes dark. The integration persists because it was never removed; no deprecation or removal PR has been filed. Confidence: high — the external shutdown is the direct, sole cause.

Proposed Remediation

Preferred: Remove the integration completely. This is the cleanest resolution given the product is gone with no successor under the same CLI name.

1. Delete src/specify_cli/integrations/iflow/ (directory and __init__.py).
2. Remove the IflowIntegration import and _register(IflowIntegration()) call from src/specify_cli/integrations/__init__.py.
3. Delete tests/integrations/test_integration_iflow.py.
4. Remove the "iflow" entry from tests/test_agent_config_consistency.py (expected-agents list at line 30, and the three test methods at lines 295–315).
5. Remove "iflow" from tests/integrations/test_registry.py (line 26).
6. Delete the "iflow" block from integrations/catalog.json (lines 267–275).
7. Remove both rows referencing iflow from docs/reference/integrations.md (lines 25, 192).
8. Remove iFlow CLI from the agent dropdown lists in .github/ISSUE_TEMPLATE/bug_report.yml, feature_request.yml, and agent_request.yml.

Alternatives:

• Soft-deprecate (add a warning): Mark the integration deprecated in its config dict and emit a CLI warning on use. Trade-off: keeps dead code alive; misleads users who see the option; requires a follow-up removal PR anyway. Not recommended.

Files likely to change:

• src/specify_cli/integrations/iflow/__init__.py (delete)
• src/specify_cli/integrations/__init__.py
• tests/integrations/test_integration_iflow.py (delete)
• tests/test_agent_config_consistency.py
• tests/integrations/test_registry.py
• integrations/catalog.json
• docs/reference/integrations.md
• .github/ISSUE_TEMPLATE/bug_report.yml
• .github/ISSUE_TEMPLATE/feature_request.yml
• .github/ISSUE_TEMPLATE/agent_request.yml

Tests to add or update:

• No new tests needed — the existing test_registry.py and test_agent_config_consistency.py suites will implicitly verify absence of iflow once the removal lines are deleted.
• Run the full test suite after removal to confirm no orphaned references remain.

Risks & Considerations

• Existing user projects: Any project that has already run specify init --integration iflow will have .iflow/ files on disk. Removing the integration from spec-kit doesn't delete those files, so existing users are unaffected at the filesystem level. No migration path is needed.
• No API breakage: iflow is not referenced as a dependency by other integrations.
• CHANGELOG: A brief entry should be added noting the removal and the reason (product discontinued 2026-04-17).

Open Questions

• None — the shutdown is confirmed and all affected files are identified.
