Summary

This PR fixes issue #3443: the agents plan rollback confirmation prompt was missing the checkpoint's descriptive label, relative creation time, and side-effects count (decisions invalidated / child plans cancelled).

Before:

Rollback plan 01HXM7A9 to checkpoint 01HXM7B2? [y/N]:

After:

Roll back plan 01HXM7A9 to checkpoint 'before-db-migration' (created 42 minutes ago)?
This will invalidate 12 decisions and cancel 2 child plans. [y/N]:

Motivation

Users performing a rollback had no context about which checkpoint they were rolling back to — only an opaque ID was shown. This made it easy to accidentally roll back to the wrong checkpoint. The enriched prompt shows the human-readable label, how long ago the checkpoint was created, and the scope of the rollback's side effects, giving users the information they need to make an informed decision.

Approach

New helper: _format_relative_time(dt)

A pure helper function that converts a datetime to a human-readable relative string (e.g. "42 minutes ago", "2 hours ago", "3 days ago"). Handles both timezone-aware and timezone-naive datetimes, and guards against future timestamps (clock skew) by returning "just now" for negative deltas.

Changes to rollback_plan

  • get_container() and checkpoint_service() are now called before the confirmation block so checkpoint metadata is available for the prompt.
  • When --yes is not passed, svc.get_checkpoint(checkpoint_id) is called to fetch the checkpoint label (metadata.reason) and creation time.
  • Decisions created after the checkpoint are counted via decision_service.list_decisions(); DecisionType.SUBPLAN_SPAWN and DecisionType.SUBPLAN_PARALLEL_SPAWN decisions are counted as child plans.
  • The side-effects line is only shown when at least one count is non-zero, and only non-zero counts are included in the message (e.g. "This will invalidate 12 decisions." when there are no child plans).
  • Falls back gracefully to the original simple prompt if checkpoint metadata cannot be fetched (catches CleverAgentsError, including ResourceNotFoundError; programming errors propagate).

Error handling

  • The outer except catches only CleverAgentsError (domain/infrastructure errors). Programming errors (AttributeError, TypeError, etc.) propagate correctly.
  • The inner except around decision counting also catches only CleverAgentsError.

Tests

Added to features/plan_cli_coverage_r2.feature and features/steps/plan_cli_coverage_r2_steps.py:

Scenario What it tests
Rollback confirmation prompt shows checkpoint label and creation time Happy path: label + relative time appear in prompt
Rollback confirmation prompt shows side effects count Side effects line with decisions + child plans
Rollback confirmation prompt falls back when checkpoint not found ResourceNotFoundError → simple prompt, no crash
Rollback confirmation prompt handles future checkpoint timestamp gracefully Negative total_seconds"just now"
Rollback confirmation prompt shows only decisions when no child plans Zero child plans → message omits child plans part
Rollback confirmation prompt counts parallel spawn decisions as child plans SUBPLAN_PARALLEL_SPAWN counted correctly

Refactored existing rollback mock helpers into _make_rollback_container() to reduce duplication and wire both checkpoint_service and decision_service mocks consistently.

Test results: 29 scenarios, 148 steps — all passing (nox -s unit_tests -- features/plan_cli_coverage_r2.feature).

Type/ label ⚠️ PR has no labels. CONTRIBUTING.md requires exactly one Type/ label (e.g., Type/Bug).

Specification Compliance

The issue (#3443) references the spec's agents plan rollback Command → Behavior → Confirmation section, which defines the prompt format as:

Roll back plan 01HXM7A9 to checkpoint 'before-db-migration' (created 42 minutes ago)?
This will invalidate 12 decisions and cancel 2 child plans. [y/N]: y

Observations:

  1. The PR adds checkpoint label display (tested via "before-db-migration" assertion)
  2. The PR adds relative creation time (tested via "created" assertion)
  3. The PR adds side-effects counting (tested via "invalidate 3 decisions" and "cancel 1 child plan" assertions)
  4. Graceful fallback when checkpoint metadata is unavailable

Concern — Prompt format ordering vs. spec: The PR description states the side-effects line is printed before the prompt, but the spec shows it after the rollback question on the same [y/N] line. The test only checks that both strings appear in the output, not their relative ordering. This may be an intentional UX improvement (showing side effects before asking for confirmation is arguably better), but it deviates from the spec's literal format. Please confirm this is intentional.

Behavior Correctness

Positive:

  • The _make_rollback_container() helper properly wires both checkpoint_service and decision_service mocks, ensuring the enriched confirmation path has all dependencies available.
  • The _make_checkpoint() helper creates proper Checkpoint domain objects with CheckpointMetadata(reason=label).
  • The fallback scenario (get_checkpoint raises ResourceNotFoundError) correctly tests graceful degradation.

Concerns:

  1. [BEHAVIOR] Existing scenario assertions weakened — The "Rollback plan succeeds with --yes flag in rich format" scenario on master checks for "Rollback Summary", "Changes Reverted", "Impact", "Post-Rollback State", and "Rollback complete" (5 assertions). The branch version only checks for "Rollback complete" and "Restored files" (2 assertions). This is a regression in test coverage — the rich output panel structure is no longer verified. Was this change intentional? If the rich output format was also changed, the test should still verify the new format's key elements.

  2. [BEHAVIOR] _format_relative_time not directly tested — The helper function is only tested indirectly through the scenario that checks for "created" in the output. This is a weak assertion — it would pass even if the time formatting is broken, as long as the word "created" appears somewhere. Consider adding a dedicated unit test or a more specific assertion (e.g., "created 42 minutes ago" or similar).

Edge Cases

  1. Missing test: zero decisions, zero child plans — The side-effects scenario tests 3 decisions and 1 child plan, but there's no test for the case where decisions exist but no child plans (should show "invalidate N decisions" without the child plans part), or vice versa. The PR description says the side-effects line is only shown "when counts > 0", but this boundary isn't tested.

  2. Missing test: subplan_parallel_spawn decision type — The PR description mentions both subplan_spawn and subplan_parallel_spawn are counted as child plans, but the test only uses DecisionType.SUBPLAN_SPAWN. If the implementation also counts SUBPLAN_PARALLEL_SPAWN, this should be tested.

  3. _format_relative_time edge cases not tested:

    • Very recent checkpoints (seconds ago)
    • Very old checkpoints (days/weeks/months ago)
    • Timezone handling — the test creates checkpoints with tzinfo=UTC, but what happens with naive datetimes? The _format_relative_time helper should handle both or explicitly require timezone-aware datetimes.
  4. Decision filtering by time — The PR description says "Decisions created after the checkpoint are counted." The test creates decisions with after_time = cp_time + timedelta(minutes=5). But what about decisions created at exactly the checkpoint time? Is this an off-by-one boundary? The test should verify the boundary condition.

Code Quality (from test file analysis)

  1. All step definitions have proper type annotations (context: Context, return -> None)
  2. Imports are at the top of the file (new imports for Checkpoint, CheckpointMetadata, UTC, Decision, DecisionType are properly placed)
  3. Mock cleanup pattern is consistent with existing code
  4. No # type: ignore suppressions
  5. ⚠️ Steps file size — The file grew from ~25.9KB to ~30KB. While I can't verify the exact line count, this file is getting large. Not a blocker, but worth monitoring against the 500-line limit.

Summary

The PR addresses the core issue requirements well — checkpoint label, creation time, and side-effects count are now shown in the confirmation prompt, with graceful fallback. The implementation approach is sound and follows existing patterns.

Items requiring attention:

# Severity Issue
1 Medium PR missing milestone (v3.7.0) and Type/ label — required by CONTRIBUTING.md
2 Medium Existing rollback rich-output scenario assertions were weakened (5 → 2 checks) — potential test coverage regression
3 Low Side-effects line ordering may differ from spec's literal format — confirm intentional
4 Low Missing edge-case tests: zero child plans, SUBPLAN_PARALLEL_SPAWN, _format_relative_time boundaries
5 Low Weak assertion for relative time display ("created" vs. a more specific pattern)

Decision: COMMENT — The core implementation looks correct and well-tested for the happy path. The metadata issues (#1) should be fixed before merge. The test coverage concerns (#2, #4, #5) are worth addressing but are not blocking.

Reviewer focus: error-handling-patterns, edge-cases, boundary-conditions

Reviewed PR #3470 which adds an enriched confirmation prompt to agents plan rollback displaying the checkpoint label, relative creation time, and side-effects count. The intent is correct and well-motivated by issue #3443. However, several issues need to be addressed before merge.


Required Changes

1. [ERROR-HANDLING] Bare except Exception: pass violates project error-handling rules

  • Location: src/cleveragents/cli/commands/plan.py — the new code in rollback_plan (two instances)

  • Issue: There are two bare except Exception: pass blocks:

    • Outer: wraps the entire checkpoint metadata fetch + decision counting
    • Inner: wraps just the decision counting logic

    These silently swallow all exceptions, including programming errors (AttributeError, TypeError, KeyError, etc.) that indicate real bugs. This directly violates the project's error-handling rules from CONTRIBUTING.md:

    "Exceptions must be allowed to propagate to the top-level handlers. Errors should never be suppressed."
    "Exceptions should only be caught when they can be handled meaningfully (e.g., for retries or resource cleanup), not just for logging."

  • Required:

    • The outer except should catch only the specific exception types that represent "checkpoint not found" scenarios (e.g., ResourceNotFoundError, CleverAgentsError). Programming errors should propagate.
    • The inner except Exception: pass around decision counting should be removed entirely or narrowed to specific expected exceptions. If the decision service is unavailable, that's a meaningful error the user should know about.
    • At minimum, unexpected exceptions should be logged at debug level so they're visible during development/troubleshooting.

2. [EDGE-CASE] _format_relative_time does not handle future timestamps

  • Location: src/cleveragents/cli/commands/plan.py_format_relative_time() function (new code around line 143)

  • Issue: If dt is in the future (e.g., due to clock skew between the CLI host and the server that created the checkpoint), total_seconds will be negative. For small future offsets (< 60s), the function returns "just now" which is acceptable. But for larger offsets, it produces nonsensical output:

    • 2 minutes in the future → total_seconds = -120-120 < 3600 is True → minutes = -120 // 60 = -2 → returns "-2 minutes ago"
  • Required: Add a guard at the top: if total_seconds < 0: return "just now". Add a Behave scenario testing this edge case.

3. [EDGE-CASE] Side-effects message displays zero counts awkwardly

  • Location: src/cleveragents/cli/commands/plan.py — side effects formatting in rollback_plan
  • Issue: The condition if decisions_count > 0 or child_plans_count > 0 means the message is shown when either count is non-zero. But the message always includes both counts: "This will invalidate 0 decisions and cancel 2 child plans." — the "0 decisions" part is misleading when there are no decisions to invalidate.
  • Required: Only include non-zero counts in the message. For example:
    • Both non-zero: "This will invalidate 12 decisions and cancel 2 child plans."
    • Only decisions: "This will invalidate 12 decisions."
    • Only child plans: "This will cancel 2 child plans."

4. [METADATA] PR missing required Type/ label and milestone

  • Location: PR metadata
  • Issue: Per CONTRIBUTING.md, every PR must have exactly one Type/ label and be assigned to the same milestone as its linked issue. This PR has no labels and no milestone. Issue #3443 is assigned to milestone v3.7.0.
  • Required: Add Type/Bug label and assign milestone v3.7.0.

Observations (Non-blocking)

  1. str(d.decision_type) is unnecessary: Since DecisionType is a StrEnum, the values already compare equal to their string representations. You can use d.decision_type in ("subplan_spawn", "subplan_parallel_spawn") directly, or better yet, compare against the enum members: d.decision_type in (DecisionType.SUBPLAN_SPAWN, DecisionType.SUBPLAN_PARALLEL_SPAWN). The latter is more type-safe and refactor-friendly.

  2. Container initialization moved before confirmation: The get_container() and checkpoint_service() calls are now executed before the user sees the confirmation prompt. This means container initialization errors will occur before the user can even decline. This is acceptable for the enriched prompt feature, but worth noting.

  3. Test coverage for subplan_parallel_spawn: The test only exercises SUBPLAN_SPAWN for child plan counting. Consider adding a scenario that includes SUBPLAN_PARALLEL_SPAWN decisions to ensure both types are counted.

  4. Spec alignment note: The spec's example confirmation prompt (line 15968) shows a simple format (Rollback plan ... to ...? [y/N]:), while the enriched format comes from the issue description. This is fine — the issue represents a spec refinement — but the spec itself should eventually be updated to match.


Good Aspects

  • Clean refactoring of rollback mock helpers into _make_rollback_container() — reduces duplication nicely
  • Proper handling of naive vs. timezone-aware datetimes in _format_relative_time
  • Graceful fallback to simple prompt when metadata is unavailable (intent is correct, execution needs refinement)
  • Well-structured Behave scenarios covering the three main cases (label, side-effects, fallback)
  • Commit message follows Conventional Changelog format correctly
  • Single atomic commit with implementation + tests together ✓

Addressed all required changes from the REQUEST CHANGES review:

Required Changes Fixed

1. [ERROR-HANDLING] Bare except Exception: pass violations

  • Outer except: Changed from except Exception to except CleverAgentsError — only catches domain/infrastructure errors (including ResourceNotFoundError which is a subclass). Programming errors (AttributeError, TypeError, etc.) now propagate correctly.
  • Inner except: Changed from except Exception to except CleverAgentsError — only catches errors from the decision service being unavailable. Programming errors propagate.

2. [EDGE-CASE] _format_relative_time future timestamp handling

  • Added guard at the top: if total_seconds < 0: return "just now" — handles clock skew between CLI host and server gracefully.
  • Added Behave scenario: "Rollback confirmation prompt handles future checkpoint timestamp gracefully"

3. [EDGE-CASE] Side-effects message with zero counts

  • Refactored to build message parts independently — only non-zero counts are included:
    • Both non-zero: "This will invalidate 12 decisions and cancel 2 child plans."
    • Only decisions: "This will invalidate 12 decisions."
    • Only child plans: "This will cancel 2 child plans."
  • Added Behave scenario: "Rollback confirmation prompt shows only decisions when no child plans"

4. [METADATA] PR missing Type/ label and milestone

  • Added Type/Bug label ✓
  • Assigned milestone v3.7.0

Additional Improvements (from non-blocking observations)

  • str(d.decision_type) removed: Now compares directly against DecisionType.SUBPLAN_SPAWN and DecisionType.SUBPLAN_PARALLEL_SPAWN enum members — more type-safe and refactor-friendly.
  • SUBPLAN_PARALLEL_SPAWN test coverage: Added Behave scenario: "Rollback confirmation prompt counts parallel spawn decisions as child plans"

Test Results

All quality gates pass:

  • nox -s lint
  • nox -s typecheck
  • nox -s unit_tests -- features/plan_cli_coverage_r2.feature ✓ (29 scenarios, 148 steps — up from 26/133)

Code Review — PR #3470 (Re-review after new commits)

Focus Areas: performance-implications, resource-usage, scalability

Overview

This PR adds checkpoint label, creation time, and side effects to the rollback confirmation prompt. The previous review was stale — new commits have been pushed. This is a fresh review of the current state.


PR Metadata (Previously Flagged — Now Fixed)

Check Status
Type label Type/Bug
Milestone v3.7.0
Closing keyword Closes #3443 (in commit)

Specification Compliance

The rollback confirmation prompt now includes:

  • Checkpoint label (e.g., 'before-db-migration')
  • Relative creation time (e.g., created 42 minutes ago)
  • Side effects count (e.g., invalidate 3 decisions and cancel 1 child plan)

This matches the spec's format for agents plan rollback confirmation.

Performance Implications (Deep Dive)

The PR adds two new service calls to the rollback confirmation path:

  1. checkpoint_service.get_checkpoint(checkpoint_id) — fetches checkpoint metadata
  2. decision_service.list_decisions(plan_id) — fetches decisions to count side effects

Performance analysis:

  • Both calls are made only when the user is prompted for confirmation (interactive path), not in the --yes flag path. This is acceptable — the user is waiting for a prompt anyway.
  • The list_decisions() call fetches all decisions for the plan to count those after the checkpoint time. For plans with many decisions (hundreds), this could be slow. Consider adding a count_decisions_after(plan_id, timestamp) method to avoid fetching all decisions just to count them.
  • The _format_relative_time() helper is a pure computation — no performance concerns.

Resource Usage

  • No new persistent resources (connections, file handles) are introduced.
  • The checkpoint and decision service calls use the existing DI-wired services — no new connections.
  • The _make_rollback_container() helper correctly wires both services for testing.

Scalability

  • The side-effects count (list_decisions() + filter) is O(n) where n is the number of decisions in the plan. For typical plans (dozens of decisions), this is fine. For very large plans (thousands of decisions), this could be slow.
  • The _format_relative_time() helper is O(1) — no scalability concerns.

⚠️ Observations (Non-blocking)

  1. list_decisions() for counting: Fetching all decisions just to count those after a timestamp is inefficient. A dedicated count_decisions_after(plan_id, timestamp) query would be more efficient at scale.

  2. Graceful fallback: The PR correctly handles the case where get_checkpoint() raises ResourceNotFoundError — the prompt falls back to the basic format. This is good defensive coding.

  3. _format_relative_time edge cases: The helper should handle timezone-naive datetimes gracefully. If checkpoint.created_at is timezone-naive and datetime.now(UTC) is timezone-aware, the subtraction will raise TypeError. Verify this is handled.

Summary

The implementation is correct and well-tested. The performance concern (fetching all decisions for counting) is non-blocking but worth tracking as a follow-up optimization. The PR metadata issues from the previous review have been addressed.
