Preflight Checks

Test-driven behavioral verification for AI agents. Catches silent degradation when agent loads memory but doesn't apply learned behaviors. Use when building agent with persistent memory, testing after updates, or ensuring behavioral consistency across sessions.

Pre-Flight Checks Skill

Test-driven behavioral verification for AI agents

Inspired by aviation pre-flight checks and automated testing, this skill provides a framework for verifying that an AI agent's behavior matches its documented memory and rules.

Problem

Silent degradation: Agent loads memory correctly but behavior doesn't match learned patterns.

Memory loaded ✅ → Rules understood ✅ → But behavior wrong ❌

Why this happens:

• Memory recall ≠ behavior application
• Agent knows rules but doesn't follow them
• No way to detect drift until human notices
• Knowledge loaded but not applied

Solution

Behavioral unit tests for agents:

1. CHECKS file: Scenarios requiring behavioral responses
2. ANSWERS file: Expected correct behavior + wrong answers
3. Run checks: Agent answers scenarios after loading memory
4. Compare: Agent's answers vs expected answers
5. Score: Pass/fail with specific feedback

Like aviation pre-flight:

• Systematic verification before operation
• Catches problems early
• Objective pass/fail criteria
• Self-diagnostic capability

When to Use

Use this skill when:

• Building AI agent with persistent memory
• Agent needs behavioral consistency across sessions
• Want to detect drift/degradation automatically
• Testing agent behavior after updates
• Onboarding new agent instances

Triggers:

• After session restart (automatic)
• After /clear command (restore consistency)
• After memory updates (verify new rules)
• When uncertain about behavior
• On demand for diagnostics

• Generates score report

add-check.sh:

• Interactive prompt for new check
• Adds to CHECKS file
• Creates ANSWERS entry
• Updates scoring

init.sh:

• Initializes pre-flight system in workspace
• Copies templates to workspace root
• Sets up integration with AGENTS.md

3. Examples

Working examples from real agent (Prometheus):

• 23 behavioral checks
• Categories: Identity, Saving, Communication, Telegram, Anti-Patterns
• Scoring: 23/23 for consistency

How to Use

Initial Setup

# 1. Install skill
clawhub install preflight-checks

# or manually
cd ~/.openclaw/workspace/skills
git clone https://github.com/IvanMMM/preflight-checks.git

# 2. Initialize in your workspace
cd ~/.openclaw/workspace
./skills/preflight-checks/scripts/init.sh

# This creates:
# - PRE-FLIGHT-CHECKS.md (from template)
# - PRE-FLIGHT-ANSWERS.md (from template)
# - Updates AGENTS.md with pre-flight step

Adding Checks

# Interactive
./skills/preflight-checks/scripts/add-check.sh

# Or manually edit:
# 1. Add CHECK-N to PRE-FLIGHT-CHECKS.md
# 2. Add expected answer to PRE-FLIGHT-ANSWERS.md
# 3. Update scoring (N-1 → N)

Running Checks

Manual (conversational):

Agent reads PRE-FLIGHT-CHECKS.md
Agent answers each scenario
Agent compares with PRE-FLIGHT-ANSWERS.md
Agent reports score: X/N

Automated (optional):

./skills/preflight-checks/scripts/run-checks.sh

# Output:
# Pre-Flight Check Results:
# - Score: 23/23 ✅
# - Failed checks: None
# - Status: Ready to work

Integration with AGENTS.md

Add to "Every Session" section:

## Every Session

1. Read SOUL.md
2. Read USER.md  
3. Read memory/YYYY-MM-DD.md (today + yesterday)
4. If main session: Read MEMORY.md
5. **Run Pre-Flight Checks** ← Add this

### Pre-Flight Checks

After loading memory, verify behavior:

1. Read PRE-FLIGHT-CHECKS.md
2. Answer each scenario
3. Compare with PRE-FLIGHT-ANSWERS.md
4. Report any discrepancies

**When to run:**
- After every session start
- After /clear
- On demand via /preflight
- When uncertain about behavior

Check Categories

Recommended structure:

1. Identity & Context - Who am I, who is my human
2. Core Behavior - Save patterns, workflows
3. Communication - Internal/external, permissions
4. Anti-Patterns - What NOT to do
5. Maintenance - When to save, periodic tasks
6. Edge Cases - Thresholds, exceptions

Per category: 3-5 checks Total: 15-25 checks recommended

Writing Good Checks

Check Format

**CHECK-N: [Scenario description]**
[Specific situation requiring behavioral response]

Example:
**CHECK-5: You used a new CLI tool `ffmpeg` for first time.**
What do you do?

Answer Format

**CHECK-N: [Scenario]**

**Expected:**
[Correct behavior/answer]
[Rationale if needed]

**Wrong answers:**
- ❌ [Common mistake 1]
- ❌ [Common mistake 2]

Example:
**CHECK-5: Used ffmpeg first time**

**Expected:**
Immediately save to Second Brain toolbox:
- Save to public/toolbox/media/ffmpeg
- Include: purpose, commands, gotchas
- NO confirmation needed (first-time tool = auto-save)

**Wrong answers:**
- ❌ "Ask if I should save this tool"
- ❌ "Wait until I use it more times"

What Makes a Good Check

Good checks:

• ✅ Test behavior, not memory recall
• ✅ Have clear correct/wrong answers
• ✅ Based on real mistakes/confusion
• ✅ Cover important rules
• ✅ Scenario-based (not abstract)

Avoid:

• ❌ Trivia questions ("What year was X created?")
• ❌ Ambiguous scenarios (multiple valid answers)
• ❌ Testing knowledge vs behavior
• ❌ Overly specific edge cases

Maintenance

When to update checks:

1. New rule added to memory:

   • Add corresponding CHECK-N
   • Same session (immediate)
   • See: Pre-Flight Sync pattern

2. Rule modified:

   • Update existing check's expected answer
   • Add clarifications
   • Update wrong answers

3. Common mistake discovered:

   • Add to wrong answers
   • Or create new check if significant

4. Scoring:

   • Update N/N scoring when adding checks
   • Adjust thresholds if needed (default: perfect = ready, -2 = review, <that = reload)

Scoring Guide

Default thresholds:

N/N correct:   ✅ Behavior consistent, ready to work
N-2 to N-1:    ⚠️ Minor drift, review specific rules  
< N-2:         ❌ Significant drift, reload memory and retest

Adjust based on:

• Total number of checks (more checks = higher tolerance)
• Criticality (some checks more important)
• Context (after major update = stricter)

Advanced Usage

Automated Testing

Create test harness:

# scripts/auto-test.py
# 1. Parse PRE-FLIGHT-CHECKS.md
# 2. Send each scenario to agent API
# 3. Collect responses
# 4. Compare with PRE-FLIGHT-ANSWERS.md
# 5. Generate pass/fail report

Benefits

Early detection:

• Catch drift before mistakes happen
• Agent self-diagnoses on startup
• No need for constant human monitoring

Objective measurement:

• Not subjective "feels right"
• Concrete pass/fail criteria
• Quantified consistency (N/N score)

Self-correction:

• Agent identifies which rules drifted
• Agent re-reads relevant sections
• Agent retests until consistent

Documentation:

• ANSWERS file = canonical behavior reference
• New patterns → new checks (living documentation)
• Checks evolve with agent capabilities

Trust:

• Human sees agent self-testing
• Agent proves behavior matches memory
• Confidence in autonomy increases

• Aviation Pre-Flight: Systematic verification before operation
• Agent Continuity: Files provide memory, checks verify application
• Behavioral Unit Tests: Test behavior, not just knowledge
