Metadata

  • Commit Message: feat(security): add safety profile model and enforcement stubs
  • Branch: feature/post-safety-profile

Background

SafetyProfile model includes allowed skill categories, sandbox/checkpoint requirements, human-approval flag, and max cost/retry limits. safety_profile field is added to the Action model. Plan-level safety resolution (plan > action > project > global) returns NotImplementedError for enforcement in local mode.

Acceptance Criteria

  • Add SafetyProfile model with allowed skill categories, sandbox/checkpoint requirements, human-approval flag, and max cost/retry limits per spec.
  • Add safety_profile field to Action model and persistence mapping (no legacy compatibility).
  • Add plan-level safety resolution stub (plan > action > project > global) that returns NotImplementedError for enforcement in local mode.
  • Document safety profile schema, defaults, and stub enforcement behavior in docs/reference/safety_profile.md.

Definition of Done

This issue is complete when:

  • All subtasks below are completed and checked off.
  • A Git commit is created where the first line of the commit message matches
    the Commit Message in Metadata exactly, followed by a blank line, then
    additional lines providing relevant details about the implementation. The
    commit body should be appropriate in size for a commit message and relatively
    complete in describing what was done.
  • The commit is pushed to the remote on the branch matching the Branch in
    Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and
    merged before this issue is marked done.

Subtasks

  • Add SafetyProfile model with allowed skill categories, sandbox/checkpoint requirements, human-approval flag, and max cost/retry limits per spec.
  • Add safety_profile field to Action model and persistence mapping (no legacy compatibility).
  • Add plan-level safety resolution stub (plan > action > project > global) that returns NotImplementedError for enforcement in local mode.
  • Document safety profile schema, defaults, and stub enforcement behavior in docs/reference/safety_profile.md.
  • Tests (Behave): Add model validation scenarios for safety profile field parsing and constraint validation.
  • Tests (Robot): Add Robot smoke test that loads a safety profile from YAML and prints serialized output.
  • Tests (ASV): Add benchmarks/safety_profile_model_bench.py for validation overhead.
  • Verify coverage >=97% via nox -s coverage_report. If coverage is <97% then review the current unit test coverage report at build/coverage.xml and use it to write new Behave based unit tests to improve coverage. Specifically, write Behave style unit tests that are descriptively named and specifically improves coverage on whichever file has the most uncovered lines by writing tests that will target the uncovered lines in the report. Once that is done rerun nox -s coverage_report to verify all tests pass and coverage is above >=97%. Only mark this as complete once coverage is >=97%, if not repeat this task as many times as is needed until coverage reaches >=97%.
  • Run nox (all default sessions, including benchmark), fix any errors if needed ensuring nox passes across entire code base, do not ignore any failure even if it seems unrelated to this commit, fix it.

Code Review Fixes Applied — SafetyProfile (commit 165d442)

All findings from the code review of commit 165d442 (branch feature/post-safety-profile) have been addressed. Below is a summary of each fix.

High Priority

ID Finding Fix
H1 Missing Alembic migration for safety_profile_json column Created c4_001_safety_profile_column.py — adds nullable Text column to actions table. Down-revision: c0_002_merge_skill_registry (current head).
H2 DEFAULT_SAFETY_PROFILE was mutable (validate_assignment=True instead of frozen=True) Replaced validate_assignment=True with frozen=True in SafetyProfile.model_config. The default constant is now immutable.
H3 No documented precedence when both SafetyProfile and AutomationProfile exist Added module docstring and class docstring documenting that SafetyProfile takes precedence for overlapping safety flags (require_sandbox, require_checkpoints, allow_unsafe_tools).

Medium Priority

ID Finding Fix
M1 No cross-field validation — max_cost_per_plan could exceed max_total_cost Added @model_validator(mode="after") that raises ValueError when max_cost_per_plan > max_total_cost.
M2 _sanitize_categories crashed on non-string/non-list input Added isinstance(v, list) and isinstance(item, str) type guards with descriptive ValueError messages.
M3 Field naming inconsistency: require_checkpoint (singular) vs spec's require_checkpoints (plural) Renamed to require_checkpoints across all files: model, feature file, step definitions, robot helper, benchmarks, vulture whitelist, and docs.

Low Priority

ID Finding Fix
L1 Robot helper _test_from_yaml() leaked temp files (delete=False without cleanup) Wrapped in try/finally to ensure os.unlink() always runs.
L2 Module docstring referenced non-existent spec section "Safety Profiles" Updated to reference correct sections: "Automation Profiles" and "Guardrails".
L3 Missing allow_unsafe_tools field (defined in spec on AutomationProfile, absent from SafetyProfile) Added allow_unsafe_tools: bool = Field(False, ...) with proper description.

Files Modified

  • src/cleveragents/domain/models/core/safety_profile.py — Core model rewrite
  • features/safety_profile.feature — 27 BDD scenarios (was 20)
  • features/steps/safety_profile_steps.py — Step definitions rewrite

There an issue with this feature:

The specification has no concept of "SafetyProfile" as a standalone model. The three boolean safety flags (require_sandbox,                    require_checkpoints, allow_unsafe_tools) are defined as fields of the Automation Profile (spec lines 27689, 27704-27706). The spec's built- n profile matrix (line 27714-27729) shows these fields living alongside the 11 confidence thresholds in a single profile.                     

     The commit introduces a separate SafetyProfile domain model with require_sandbox, require_checkpoints, and allow_unsafe_tools — creating an overlapping authority with the existing AutomationProfile. The documentation (safety_profile.md:65-79) attempts to resolve this by stating "SafetyProfile takes precedence for overlapping safety flags," but the specification never defines this precedence — it places all 14 fields (11 thresholds + 3 booleans) on one profile.

     Risk: When AutomationProfile says require_sandbox: false but SafetyProfile says require_sandbox: true, there's no spec-defined resolution. 
     The precedence rule exists only in the new docs, not in the specification.           
                                                                    
     Recommendation: Either (a) treat SafetyProfile as a subset/view extracted from AutomationProfile with a clear mapping, or (b) get the spec amended to recognize SafetyProfile as a separate concept. At minimum, document this as a deviation from the spec, not as spec-aligned behavior.  

I think that AutomationProfile should inherit those properties from the SafetyProfile or some other common ancestor

Good catch, Luis. You're right that this creates overlapping authority between SafetyProfile and AutomationProfile for the three shared booleans, and the precedence rule exists only in the new docs rather than the spec.

I think the cleanest resolution is composition: remove require_sandbox, require_checkpoints, and allow_unsafe_tools from AutomationProfile's top-level fields and instead give AutomationProfile a safety: SafetyProfile field. This way:

  • SafetyProfile becomes the single source of truth for all safety constraints (the 3 booleans + the new fields like allowed_skill_categories, cost limits, etc.)
  • AutomationProfile composes it rather than duplicating it — no dual authority
  • Existing built-in profiles would set their safety values via the nested safety field (e.g., safety=SafetyProfile(require_sandbox=True, ...))
  • Actions that only need safety constraints (without full automation thresholds) can use SafetyProfile standalone

One thing to reconcile: AutomationGuard.max_total_cost and SafetyProfile.max_total_cost have overlapping names but different scopes — Guard's is a per-invocation budget check while SafetyProfile's is a broader plan-level limit. These should be clearly distinguished in naming or docs.

I'll update the spec to recognize SafetyProfile as a first-class extracted concept rather than treating this as a deviation. Please refactor the PR with the composition approach before we merge.

Spec & ADR Updates for SafetyProfile Composition

The specification and architecture docs have been updated to recognize SafetyProfile as a first-class composed sub-model within AutomationProfile. The following files were changed:

New

  • docs/adr/ADR-041-safety-profile-extraction.md — New ADR documenting the decision to extract safety constraints into a composed SafetyProfile sub-model. Covers the composition design, field schema, relationship to Guards, constraints, consequences, and alternatives considered (inheritance, mixin, flat).

Updated

  • docs/specification.md — Glossary now defines Safety Profile as a concept. The "Automatable Tasks" section is split into threshold fields and a new "Safety Profile (Composed Sub-Model)" sub-section. The built-in profile matrix groups safety fields under safety.* prefix. YAML examples updated to use nested safety: block.
  • docs/adr/ADR-017-automation-profiles.md — Profile Fields table updated to show safety: SafetyProfile as a composed field instead of flat booleans. Built-in profiles table, constraints, and risks updated. Cross-reference to ADR-041 added.
  • docs/reference/automation_profiles.md — "Safety Fields" section renamed to "Safety Profile (Composed Sub-Model)" with full field table. Built-in profile matrix updated. Custom profile and guards YAML examples updated to use nested safety: block.
  • docs/schema/automation_profile.schema.yaml — Flat require_sandbox/require_checkpoints/allow_unsafe_tools replaced with nested safety object including all SafetyProfile fields.
  • docs/adr/index.md — ADR-041 added to Tier 3 inventory. ADR-017 summary updated to note SafetyProfile composition.

Luis — please align the PR refactor with these spec changes. The key implementation points:

  1. AutomationProfile gets a safety: SafetyProfile field (composition, not inheritance)
  2. Remove require_sandbox, require_checkpoints, allow_unsafe_tools from AutomationProfile's top level
  3. All eight built-in profiles set safety values via safety=SafetyProfile(...)
  4. SafetyProfile model stays as-is (frozen, with cross-field validation) but is now the sole owner of those fields
