Implementation Details

Phase 0: Integration Contract and ADR ✅

Created:

docs/adr/ADR-0001-openhands-execution-backend.md
docs/integrations/openhands.md
config/openhands.yaml

Key Decisions:

OpenHands owns execution, Agile-V owns acceptance
Skills teach, hooks enforce
Evidence validation is independent of agent claims
L3/L4 changes cannot be self-approved by agents

Files:

Integration responsibilities documented
Non-goals explicit (no self-approval, no bypassing briefs)
Risk mitigation strategies defined

Phase 1: OpenHands CLI Namespace ✅

Created:

src/agilev/openhands/__init__.py
src/agilev/openhands/scaffold.py (1400+ lines)
Extended src/agilev/cli.py with openhands subcommand group

Commands:

agilev openhands init      # Generate integration files
agilev openhands doctor    # Validate setup
agilev openhands scaffold  # Regenerate files
agilev openhands validate  # Validate session for task
agilev openhands handoff   # Show handoff report

Features:

Idempotent initialization (--force to overwrite)
Comprehensive validation (21 checks across skills, hooks, policies, config)
Force regeneration support
Task-specific validation

Phase 2: OpenHands Skills ✅

Created Skills:

agile-v-core (.agents/skills/agile-v-core/SKILL.md)
- Core workflow rules
- Task brief requirement before implementation
- Evidence-controlled acceptance
- Risk-level guidance (L0-L4)
- Never: remove tests, weaken security, self-approve L3/L4
agile-v-builder (.agents/skills/agile-v-builder/SKILL.md)
- Implementation workflow (inspect → plan → edit → test → document)
- Scope minimization
- Test-first mindset
- Evidence collection guidance
- Implementation summary requirements
agile-v-verifier (.agents/skills/agile-v-verifier/SKILL.md)
- Independent verification from fresh context
- Acceptance criteria mapping
- Edge case detection
- Scope creep detection
- Verification report requirements
- Cannot self-approve L3/L4
agile-v-evidence (.agents/skills/agile-v-evidence/SKILL.md)
- Evidence bundle maintenance
- Never fabricate evidence
- Git/CI as source of truth
- OpenHands metadata extensions
agile-v-risk-classifier (.agents/skills/agile-v-risk-classifier/SKILL.md)
- L0-L4 classification guidance
- Evidence requirements by level
- Examples for each level
- Escalation rules (when uncertain, escalate)

Design:

Concise enough to load efficiently
Reference Agile-V artifacts (don't duplicate methodology)
Progressive disclosure (load based on mode: builder/verifier)

Phase 3: OpenHands Hooks ✅

Created Hooks:

Hook	Lifecycle	Blocking	Purpose
`enforce_task_brief.sh`	`user_prompt_submit`	Yes	Require task ID/brief before implementation
`block_unsafe_commands.sh`	`pre_tool_use` (terminal)	Yes	Block destructive commands
`validate_scope.sh`	`pre_tool_use` (all)	Yes	Check scope (MVP: allow + warn)
`log_tool_usage.sh`	`post_tool_use`	No	Append to tool log (JSONL)
`collect_session_metadata.sh`	`session_start`	No	Record session metadata
`validate_evidence_on_stop.sh`	`stop`	Yes	Block until evidence passes
`generate_handoff_on_session_end.sh`	`session_end`	No	Generate handoff summary

Hook Configuration:

.openhands/hooks.json - Hook registry with matchers and timeouts
Hooks return JSON: {"decision": "allow|deny", "reason": "..."}
Blocking hooks exit with code 2 on deny
All hooks are executable (chmod +x)

Dangerous Command Patterns Blocked:

rm -rf /
dd if=
mkfs
Fork bombs
chmod 777
curl ... | sudo bash
And more...

Setup Script:

.openhands/setup.sh - Validates environment, makes hooks executable, checks for agilev CLI

Phase 4: Task Context Resolution ✅

Created:

src/agilev/task_context.py - TaskContextResolver class

Resolution Order:

Explicit CLI option (--task AAV-001)
Environment variable (AGILEV_TASK_ID=AAV-001)
Git branch name (aav-001-* pattern)
GitHub metadata (GITHUB_PR_TITLE, GITHUB_ISSUE_TITLE)
Latest modified task (if unambiguous within 24 hours)
Fail with clear error if ambiguous

Features:

Task ID normalization (AAV-001 → AAV-0001)
Fail-closed on ambiguity (prevents writing to wrong task)
Branch pattern matching (case-insensitive)
Validation of task existence

Policy Files Created ✅

Policy Configuration:

config/policies/openhands_dangerous_commands.yaml - Blocked command patterns
config/policies/scope_policy.yaml - Default scope behavior, security-sensitive paths
config/policies/approval_policy.yaml - Human approval requirements by risk level
config/policies/evidence_policy.yaml - Evidence requirements by risk level
config/policies/risk_level_policy.yaml - Risk classification guidance and auto-classification

Highlights:

L0: Documentation (no approval)
L1: Tests or rationale (no approval)
L2: Passing tests + verifier (reviewer approval)
L3: L2 + rollback path (domain owner approval)
L4: L3 + simulation/HIL/formal + traceability (formal approval)

Create a Task

agilev new --title "Add retry handling" --risk L2

Run OpenHands

Currently: Launch OpenHands manually and point to the repository. Skills and hooks activate automatically.

Future: agilev openhands run --task AAV-0001 --mode builder

Validate Session

agilev openhands validate --task AAV-0001

View Handoff

agilev openhands handoff --task AAV-0001

Next Steps (Remaining Phases)

Phase 5: Extend Evidence Bundle Schema

Add agent_execution section (engine, mode, session_id, tool_log_path)
Add scope_control section (allowed_paths, blocked_paths, violations)
Add verification section (builder_summary, verifier_report, result)
Maintain backward compatibility with existing evidence bundles

Phase 6: Implement Evidence Adapter

agilev openhands evidence collect --task AAV-XXXX
Map OpenHands tool log → evidence bundle
Map Git diff → changed_files (truth over agent claims)
Map test outputs → tests.results
Map CI results → checks
Never fabricate passed tests

Phase 7: Add Scope Policy Enforcement

Parse task brief YAML frontmatter for allowed/blocked paths
Compare changed files (from Git) against allowed paths
Block or warn on out-of-scope changes
Detect dependency changes (Python, Node, Rust, Go, Java)
Flag public API changes
Full implementation of validate_scope.sh hook

Phase 8: Add Builder/Verifier Workflow

agilev openhands run --task AAV-XXXX --mode builder
agilev openhands verify --task AAV-XXXX --fresh-context
Separate builder and verifier sessions
Verifier read-only by default
Verifier report schema and validation
L2+ requires verifier

Phase 9: Add GitHub Actions Workflows

.github/workflows/agilev-openhands-builder.yml
.github/workflows/agilev-openhands-verifier.yml
.github/workflows/agilev-gates.yml
Label-driven automation
PR comment with evidence summary
Merge blocking on failed gates

Phase 10: Add Event Ledger

Append-only event log (events.jsonl)
Hash chain for tamper detection
Event types: TaskBriefCreated, ToolUsed, EvidenceUpdated, etc.
Ledger validation command

Phase 11: Add Reports and Handoff

agilev report --task AAV-XXXX
Deterministic from files/evidence (not agent memory)
Suitable for PR comments and human review
Handoff includes: objective, changed files, tests, risks, next action

Phase 12: Documentation and Examples

Quickstart guide
Integration patterns (builder + verifier)
Example task packages (L0-L4)
Troubleshooting guide
Video walkthrough

Test Coverage

✅ OpenHandsScaffold initialization
✅ Doctor validation (21 checks)
✅ Task context resolution
✅ File creation and permissions
⏳ Hook execution (not yet tested)
⏳ Evidence adapter (not yet implemented)
⏳ Scope validation (not yet implemented)

Risks and Mitigations

Risk	Mitigation	Status
Agent bypasses task brief	`enforce_task_brief.sh` hook blocks	✅ Implemented
Agent removes tests	Skill forbids; evidence tracks delta	✅ Skill documented
Agent expands scope	`validate_scope.sh` hook (MVP: warn)	⏳ Partial (warns only)
Agent self-approves L3/L4	Policy enforces human approval; CI blocks	✅ Policy defined
Agent fabricates evidence	Evidence adapter uses Git/CI truth	⏳ Not yet implemented
Hook or skill ignored	Stop hook blocks; CI fails	✅ Stop hook implemented

Lessons Learned

What Worked Well

Skill-based progressive disclosure: Skills are concise, loadable, and extensible
Hook-based enforcement: Mechanical gates that don't rely on agent compliance
Policy-driven design: YAML policies are human-readable and version-controllable
Task context resolution: Flexible resolution order reduces friction
Idempotent scaffolding: Safe to re-run, respects existing files

Challenges

Python environment issues: Testing required PYTHONPATH workarounds
Scope validation complexity: Full implementation deferred to Phase 7
Evidence schema extension: Backward compatibility requires careful design
GitHub Actions integration: Requires OpenHands SDK or wrapper scripts

Design Trade-offs

MVP scope validation: Allow + warn vs. strict blocking (chose allow for MVP)
Hook language: Bash vs. Python (chose Bash for simplicity and no dependencies)
Evidence source: Agent claims vs. Git/CI (chose Git/CI as source of truth)
Skill size: Comprehensive vs. concise (chose concise for loadability)

Conclusion

Successfully implemented the MVP scope of the OpenHands integration for Agentic Agile-V. The foundation is solid:

✅ Control separation: Agile-V controls acceptance, OpenHands executes
✅ Skills teach: Five skills for progressive disclosure
✅ Hooks enforce: Seven lifecycle hooks with mechanical gates
✅ Policies guide: Risk-based evidence requirements
✅ Context resolves: Flexible task ID resolution

The integration is additive (doesn't break existing workflows), safe (fail-closed on ambiguity), and extensible (ready for Phases 5-12).

Next Priority: Phase 5 (Evidence schema extension) and Phase 6 (Evidence adapter) to close the loop between OpenHands execution and Agile-V validation.
