Summary

CONTAINER_RESOURCE_TYPES in execution_environment_resolver.py includes "devcontainer-file", which is a read-only configuration file resource (not a running container). This causes validate_container_available() to return True when only a devcontainer-file is linked to a project — even though no actual container is available for tool execution. Tools will then be routed to "container" execution but fail because no container is running.

What Was Tested

Code-level analysis of:

  • src/cleveragents/application/services/execution_environment_resolver.pyCONTAINER_RESOURCE_TYPES (lines 54-60)
  • src/cleveragents/application/services/_resource_registry_data.pydevcontainer-file definition (lines 284-301)

Expected Behavior

validate_container_available() should only return True when an actual runnable container resource is linked — i.e., container-instance or devcontainer-instance. A devcontainer-file is a configuration file, not a container.

Per _resource_registry_data.py lines 284-301:

{
    "name": "devcontainer-file",
    "description": "A single devcontainer.json configuration file resource.",
    "capabilities": {
        "read": True,
        "write": False,
        "sandbox": False,    # NOT a sandbox
        "checkpoint": False,
    },
}

The devcontainer-file resource has sandbox: False and write: False — it cannot execute tools.

Actual Behavior

CONTAINER_RESOURCE_TYPES (lines 54-60):

CONTAINER_RESOURCE_TYPES: frozenset[str] = frozenset(
    {
        "container-instance",
        "devcontainer-instance",
        "devcontainer-file",   # ← BUG: this is a config file, not a container
    }
)

When validate_container_available(["devcontainer-file"]) is called, it returns True because "devcontainer-file" is in CONTAINER_RESOURCE_TYPES. The tool is then routed to container execution, but no container is actually running.

Impact

  • Projects that have a devcontainer-file resource linked (but no devcontainer-instance) will pass container availability validation
  • Tools routed to container execution will fail with confusing errors because no container is running
  • The error message will say "Container execution is not available" (from ToolRunner) rather than the more accurate ContainerUnavailableError message

Code Location

  • src/cleveragents/application/services/execution_environment_resolver.py, line 58

Suggested Fix

Remove "devcontainer-file" from CONTAINER_RESOURCE_TYPES:

CONTAINER_RESOURCE_TYPES: frozenset[str] = frozenset(
    {
        "container-instance",
        "devcontainer-instance",
    }
)

## Summary `CONTAINER_RESOURCE_TYPES` in `execution_environment_resolver.py` includes `"devcontainer-file"`, which is a read-only configuration file resource (not a running container). This causes `validate_container_available()` to return `True` when only a `devcontainer-file` is linked to a project — even though no actual container is available for tool execution. Tools will then be routed to "container" execution but fail because no container is running. ## What Was Tested Code-level analysis of: - `src/cleveragents/application/services/execution_environment_resolver.py` — `CONTAINER_RESOURCE_TYPES` (lines 54-60) - `src/cleveragents/application/services/_resource_registry_data.py` — `devcontainer-file` definition (lines 284-301) ## Expected Behavior `validate_container_available()` should only return `True` when an actual runnable container resource is linked — i.e., `container-instance` or `devcontainer-instance`. A `devcontainer-file` is a configuration file, not a container.

PR Review — Issue #5539 vs PR #10598

Tier 3: sonnet — Review Complete

Summary

This issue (#5539) is being addressed by PR #10598 (fix(container): remove devcontainer-file from CONTAINER_RESOURCE_TYPES). A full review of both has been completed.


1. Does PR #10598 adequately address this issue?

Yes — fully and correctly.

The issue reports that "devcontainer-file" is incorrectly included in CONTAINER_RESOURCE_TYPES in execution_environment_resolver.py, causing validate_container_available() to return True when only a read-only config file is linked (not a real container). The suggested fix was to remove "devcontainer-file" from the frozenset.

PR #10598 implements exactly that fix:

  • Removes "devcontainer-file" from CONTAINER_RESOURCE_TYPES
  • Only container-instance and devcontainer-instance now qualify as available containers
  • Tests updated to assert devcontainer-file is NOT in the frozenset

2. Is there anything remaining to do?

No implementation work remains. The fix is complete and correct.

However, there are minor non-blocking housekeeping items noted in the PR review:

  • The PR review by HAL9001 is marked stale (review was on commit d2fb54b, current head is ca050538) — a re-review or re-approval may be needed before merge
  • No milestone assigned on PR #10598 (issue is in v3.6.0)
  • Missing Forgejo dependency link (PR should block issue #5539)
  • Priority label on the issue is Priority/Medium — the reviewer noted bugs should have Priority/Critical per triaging rules

3. Should this issue be closed?

No — not manually. Issue #5539 should remain open and will be automatically closed when PR #10598 is merged (the PR body contains Closes #5539).

CI Status of PR #10598

The most recent complete CI run (run #16331) shows all gates passing:

  • lint ✓, typecheck ✓, security ✓, quality ✓, build ✓, helm ✓, e2e_tests ✓, unit_tests ✓, integration_tests ✓, docker ✓

A newer run (#16348) is still in progress (unit_tests, integration_tests, coverage, docker pending), but the complete run confirms the fix is sound.

Mergeability

PR #10598 shows "mergeable": true — no merge conflicts.

Recommendation

PR #10598 is ready to merge. Once merged, issue #5539 will be automatically closed. No further implementation work is needed.
