Summary

The automatic checkpoint trigger names and config key used in the implementation do not match the specification. This is a critical deviation that blocks v3.3.0 acceptance criteria because users configuring core.checkpoints.auto_create_on with spec-documented values (on_tool_write, on_tool_write_complete) will find them silently ignored.

Expected Behavior (from spec §Automatic Checkpoint Triggers, §Configuration Reference)

Config key: sandbox.checkpoint.auto-create-on
Default value: ["on_tool_write", "on_tool_write_complete", "on_subplan_spawn", "on_error"]
Env var: CLEVERAGENTS_CHECKPOINT_AUTO_CREATE_ON

Trigger names:

Trigger	When
`on_tool_write`	Before each write-tool execution
`on_tool_write_complete`	After each write-tool execution
`on_subplan_spawn`	Before first subplan execution attempt
`on_error`	When the Execute phase fails

From spec (line 30722):

[sandbox.checkpoint]
auto-create-on = ["on_tool_write", "on_tool_write_complete", "on_subplan_spawn", "on_error"]

Actual Behavior

Config key: core.checkpoints.auto_create_on (wrong namespace and key name)
Default value: "before_tool_execute,after_tool_execute,on_subplan_spawn,on_error" (wrong trigger names)

From src/cleveragents/application/services/config_service.py (line 480–493):

_register(
    "core",
    "checkpoints.auto_create_on",
    str,
    "before_tool_execute,after_tool_execute,on_subplan_spawn,on_error",
    ...
)

From src/cleveragents/tool/runner.py (lines 55–56):

"before_tool_execute",
"after_tool_execute",

Impact

Config key mismatch: Users following the spec and setting sandbox.checkpoint.auto-create-on will have no effect. The implementation reads core.checkpoints.auto_create_on.
Trigger name mismatch: Users disabling specific triggers by name (e.g., removing on_tool_write from the list) will find the trigger still fires because the implementation checks for before_tool_execute.
Test misalignment: features/checkpoint_auto_triggers.feature tests before_tool_execute/after_tool_execute — these tests pass but validate the wrong names.
v3.3.0 deliverable #7 at risk: The checkpoint system is functional but not spec-compliant in its configuration interface.

Steps to Reproduce

Read spec §Configuration Reference → sandbox.checkpoint.auto-create-on
Set CLEVERAGENTS_CHECKPOINT_AUTO_CREATE_ON=on_tool_write,on_subplan_spawn (disabling on_tool_write_complete)
Observe: after_tool_execute checkpoint still fires because the env var is parsed but the trigger name on_tool_write_complete is never checked — the code checks after_tool_execute

Code Locations

src/cleveragents/application/services/config_service.py lines 480–493 (wrong key namespace and trigger names)
src/cleveragents/tool/runner.py lines 55–56, 476, 480, 518, 522 (wrong trigger names)
features/checkpoint_auto_triggers.feature line 127–130 (tests validate wrong names)

Fix Required

Change config key from core.checkpoints.auto_create_on → sandbox.checkpoint.auto-create-on
Change trigger names from before_tool_execute/after_tool_execute → on_tool_write/on_tool_write_complete
Update ToolRunner to check on_tool_write/on_tool_write_complete
Update feature tests to use spec-compliant trigger names

Architect Note — Checkpoint Trigger Names

From: architect-1 (continuous architecture supervisor)
Date: 2026-04-09

This issue is already covered by PR #5163 (docs(spec): align checkpoint trigger names and config key path with implementation), which is awaiting human review.

Architect Assessment: In this case, the implementation names (before_tool_execute, after_tool_execute) are more precise than the spec names (on_tool_write, on_tool_write_complete). The implementation correctly gates these triggers on write tools via the _tool_writes flag — the trigger fires before/after tool execution, not just for write tools. The implementation names better describe the actual behavior.

Recommendation: Merge PR #5163 to update the spec to match the implementation. This is one of the rare cases where the implementation improved on the spec's naming.

Issue triaged by project owner:

State: Verified
Priority: Critical — Checkpoint auto-trigger names and config key namespace in the implementation do not match the specification. This directly blocks v3.3.0 acceptance criteria since checkpoint triggers are a core deliverable of that milestone.
Milestone: v3.3.0 — Corrections + Subplans + Checkpoints. Checkpoint trigger naming is explicitly part of the v3.3.0 spec (see spec PR #5163 which aligns trigger names).
Story Points: 3 — M — Renaming trigger constants and config keys is targeted, but requires updating all references and ensuring backward compatibility is handled.
MoSCoW: Must Have — The spec defines exact trigger names. Any mismatch means the checkpoint system cannot be configured correctly per the spec, blocking the v3.3.0 milestone.
Parent Epic: Needs linking to the Checkpoint epic under Legendary #377.
