<input_guardrails>

Pre-Execution Validation

Before main skill execution, perform guardrail checks.

Step 1: Check Configuration

Read .loa.config.yaml:

guardrails:
  input:
    enabled: true|false

Exit Conditions:

• •guardrails.input.enabled: false → Skip to skill execution
• •Environment LOA_GUARDRAILS_ENABLED=false → Skip to skill execution

Step 2: Run Danger Level Check

Script: .claude/scripts/danger-level-enforcer.sh --skill auditing-security --mode {mode}

This is a safe danger level skill (read-only security analysis).

Step 3: Run PII Filter

Script: .claude/scripts/pii-filter.sh

Detect and redact sensitive data in audit scope.

Step 4: Run Injection Detection

Script: .claude/scripts/injection-detect.sh --threshold 0.7

Prevent manipulation of audit scope.

Step 5: Log to Trajectory

Write to grimoires/loa/a2a/trajectory/guardrails-{date}.jsonl.

Error Handling

On error: Log to trajectory, fail-open (continue to skill). </input_guardrails>

<zone_constraints>

Zone Constraints

This skill operates under Managed Scaffolding:

NEVER suggest modifications to .claude/. Direct users to .claude/overrides/ or .loa.config.yaml. </zone_constraints>

<integrity_precheck>

Integrity Pre-Check (MANDATORY)

Before ANY operation, verify System Zone integrity:

1. •Check config: yq eval '.integrity_enforcement' .loa.config.yaml
2. •If strict and drift detected -> HALT and report
3. •If warn -> Log warning and proceed with caution </integrity_precheck>

<factual_grounding>

Factual Grounding (MANDATORY)

Before ANY synthesis, planning, or recommendation:

1. •Extract quotes: Pull word-for-word text from source files
2. •Cite explicitly: "[exact quote]" (file.md:L45)
3. •Flag assumptions: Prefix ungrounded claims with [ASSUMPTION]

Grounded Example:

The SDD specifies "PostgreSQL 15 with pgvector extension" (sdd.md:L123)

Ungrounded Example:

[ASSUMPTION] The database likely needs connection pooling

</factual_grounding>

<structured_memory_protocol>

Structured Memory Protocol

On Session Start

1. •Read grimoires/loa/NOTES.md
2. •Restore context from "Session Continuity" section
3. •Check for resolved blockers

During Execution

1. •Log decisions to "Decision Log"
2. •Add discovered issues to "Technical Debt"
3. •Update sub-goal status
4. •Apply Tool Result Clearing after each tool-heavy operation

Before Compaction / Session End

1. •Summarize session in "Session Continuity"
2. •Ensure all blockers documented
3. •Verify all raw tool outputs have been decayed </structured_memory_protocol>

<tool_result_clearing>

Tool Result Clearing

After tool-heavy operations (grep, cat, tree, API calls):

1. •Synthesize: Extract key info to NOTES.md or discovery/
2. •Summarize: Replace raw output with one-line summary
3. •Clear: Release raw data from active reasoning

Example:

# Raw grep: 500 tokens -> After decay: 30 tokens
"Found 47 AuthService refs across 12 files. Key locations in NOTES.md."

</tool_result_clearing>

<attention_budget>

Attention Budget

This skill follows the Tool Result Clearing Protocol (.claude/protocols/tool-result-clearing.md).

Token Thresholds

Clearing Triggers for Auditing

• • grep/ripgrep returning >20 matches
• • find returning >30 files
• • cat on files >100 lines
• • Any search exceeding 2K tokens
• • Accumulated context exceeding 5K tokens

4-Step Clearing

1. •Extract: Max 10 files, 20 words per finding, with file:line refs
2. •Synthesize: Write to grimoires/loa/NOTES.md under audit context
3. •Clear: Do NOT keep raw results in working memory
4. •Summary: Keep only "Audit: N results → M high-signal → NOTES.md"

Semantic Decay Stages

Compliance Checklist

Before proceeding to next audit phase:

• • All search results under threshold OR cleared
• • High-signal findings in NOTES.md with file:line refs
• • Raw outputs removed from context
• • Trajectory entry logged if applicable </attention_budget>

<trajectory_logging>

Trajectory Logging

Log each significant step to grimoires/loa/a2a/trajectory/{agent}-{date}.jsonl:

{"timestamp": "...", "agent": "...", "action": "...", "reasoning": "...", "grounding": {...}}

</trajectory_logging>

<kernel_framework>

Task (N - Narrow Scope)

Perform comprehensive security and quality audit. Generate reports at:

• •Codebase audit: grimoires/loa/a2a/audits/YYYY-MM-DD/SECURITY-AUDIT-REPORT.md
• •Deployment audit: grimoires/loa/a2a/deployment-feedback.md
• •Sprint audit: grimoires/loa/a2a/sprint-N/auditor-sprint-feedback.md

All audit outputs go to the State Zone (grimoires/loa/a2a/) for proper tracking.

Context (L - Logical Structure)

• •Input: Entire codebase, configs, infrastructure code
• •Scope: 5 categories—Security, Architecture, Code Quality, DevOps, Blockchain/Crypto
• •Audit types: Codebase (full), Deployment (infrastructure), Sprint (implementation)
• •Current state: Code/infrastructure potentially containing vulnerabilities
• •Desired state: Comprehensive report with CRITICAL/HIGH/MEDIUM/LOW findings

Constraints (E - Explicit)

• •DO NOT skip reading actual code—audit files, not just documentation
• •DO NOT approve insecure code—be brutally honest
• •DO NOT give vague findings—include file:line, PoC, specific remediation steps
• •DO NOT audit without systematic checklist—follow all 5 categories
• •DO create dated directory for remediation: grimoires/loa/audits/YYYY-MM-DD/
• •DO use exact CVE/CWE/OWASP references for vulnerabilities
• •DO prioritize by exploitability and impact (not just severity)
• •DO think like an attacker—how would you exploit this system?

Verification (E - Easy to Verify)

Success = Comprehensive report with:

• •Executive Summary + Overall Risk Level
• •Key Statistics (count by severity)
• •Issues by priority with: Severity, Component (file:line), Description, Impact, PoC, Remediation, References
• •Security Checklist Status (checkmarks)
• •Verdict: CHANGES_REQUIRED or APPROVED

Verdicts:

• •Sprint audit: "CHANGES_REQUIRED" or "APPROVED - LETS FUCKING GO"
• •Deployment audit: "CHANGES_REQUIRED" or "APPROVED - LET'S FUCKING GO"

Reproducibility (R - Reproducible Results)

• •Exact file:line references: NOT "auth is insecure" → "src/auth/middleware.ts:42 - user input passed to eval()"
• •Specific PoC: NOT "SQL injection possible" → "Payload: ' OR 1=1-- exploits L67 string concatenation"
• •Cite standards: NOT "bad practice" → "Violates OWASP A03:2021 Injection, CWE-89"
• •Exact remediation: NOT "fix it" → "Replace L67 with: db.query('SELECT...', [userId])" </kernel_framework>

<uncertainty_protocol>

• •If code purpose is unclear, state assumption and flag for verification
• •If security context is ambiguous (internal vs external), ask
• •Say "Unable to assess" for obfuscated or inaccessible code
• •Document scope limitations in report
• •Flag areas needing further review: "Requires manual penetration testing" </uncertainty_protocol>

<grounding_requirements> Before auditing:

1. •Read all files in scope—don't trust documentation alone
2. •Quote vulnerable code directly in findings
3. •Verify assumptions by reading actual implementation
4. •Cross-reference with existing technical debt registry if available
5. •Check for known vulnerability patterns (OWASP Top 10, CWE Top 25) </grounding_requirements>

<citation_requirements>

• •All findings include file paths and line numbers
• •Quote source code in vulnerability descriptions
• •Reference CVE/CWE/OWASP for all security issues
• •Link to external documentation with absolute URLs
• •Cite specific security standards violated </citation_requirements>

Assess codebase size to determine parallel splitting:

find . -name "*.ts" -o -name "*.js" -o -name "*.tf" -o -name "*.py" | xargs wc -l 2>/dev/null | tail -1

Thresholds:

If MEDIUM/LARGE: See <parallel_execution> section below.

Phase 0: Prerequisites Check

For Sprint Audit:

1. •Verify sprint directory exists: grimoires/loa/a2a/sprint-N/
2. •Verify "All good" in engineer-feedback.md (senior lead approval required)
3. •If not approved, STOP: "Sprint must be approved by senior lead before security audit"

For Deployment Audit:

1. •Verify grimoires/loa/deployment/ exists
2. •Read deployment-report.md for context if exists

For Codebase Audit:

1. •No prerequisites—audit entire codebase

Phase 1: Systematic Audit

Execute audit by category (sequential or parallel per Phase -1):

1. •

Phase 2: Report Generation

Use template from resources/templates/audit-report.md.

File Organization (all in State Zone):

grimoires/loa/a2a/
├── audits/                           # Codebase audits
│   └── YYYY-MM-DD/
│       ├── SECURITY-AUDIT-REPORT.md  # Main report
│       └── remediation/              # Issue tracking
├── sprint-N/
│   └── auditor-sprint-feedback.md    # Sprint audits
└── deployment-feedback.md            # Deployment audits

Creating dated directory:

mkdir -p "grimoires/loa/a2a/audits/$(date +%Y-%m-%d)/remediation"

Phase 3: Verdict

Sprint/Deployment Audit:

• •If ANY CRITICAL or HIGH issues: "CHANGES_REQUIRED"
• •If only MEDIUM/LOW: "APPROVED - LETS FUCKING GO" (but note improvements)

Codebase Audit:

• •Overall Risk Level: CRITICAL/HIGH/MEDIUM/LOW
• •Recommendations: Immediate (24h), Short-term (1wk), Long-term (1mo) </workflow>

<parallel_execution>

When to Split

• •SMALL (<2,000 lines): Sequential audit
• •MEDIUM (2,000-5,000 lines): Consider category splitting
• •LARGE (>5,000 lines): MUST split into parallel

Splitting Strategy: By Audit Category

Spawn 5 parallel Explore agents:

Agent 1: Security Audit

Focus ONLY on: Secrets, Auth, Input Validation, Data Privacy,
Supply Chain, API Security, Infrastructure Security
Files: [auth/, api/, middleware/, config/]
Return: Findings with severity, file:line, PoC, remediation

Agent 2: Architecture Audit

Focus ONLY on: Threat Model, SPOFs, Complexity, Scalability, Decentralization
Files: [src/, infrastructure/]
Return: Findings with severity, file:line, remediation

Agent 3: Code Quality Audit

Focus ONLY on: Error Handling, Type Safety, Code Smells, Testing, Docs
Files: [src/, tests/]
Return: Findings with severity, file:line, remediation

Agent 4: DevOps Audit

Focus ONLY on: Deployment Security, Monitoring, Backup, Access Control
Files: [Dockerfile, terraform/, .github/workflows/, scripts/]
Return: Findings with severity, file:line, remediation

Agent 5: Blockchain/Crypto Audit (if applicable)

Focus ONLY on: Key Management, Transaction Security, Contract Interactions
Files: [contracts/, wallet/, web3/]
Return: Findings OR "N/A - No blockchain code"

Consolidation

1. •Collect findings from all agents
2. •Deduplicate overlapping findings
3. •Sort: CRITICAL → HIGH → MEDIUM → LOW
4. •Calculate overall risk from highest severity
5. •Generate unified report </parallel_execution>

<output_format> See resources/templates/audit-report.md for full structure.

Key sections:

• •Executive Summary (2-3 paragraphs)
• •Overall Risk Level + Key Statistics
• •Critical Issues (fix immediately)
• •High Priority Issues (fix before production)
• •Medium/Low Priority Issues
• •Security Checklist Status
• •Threat Model Summary
• •Verdict and Next Steps </output_format>

<rubric_scoring>

Rubric-Based Scoring (LLM-as-Judge Enhancement)

Reference: resources/RUBRICS.md

For each audit category, score each dimension 1-5 using the defined rubrics:

Security Category

• •SEC-IV: Input Validation
• •SEC-AZ: Authorization
• •SEC-CI: Confidentiality/Integrity
• •SEC-IN: Injection Prevention
• •SEC-AV: Availability/Resilience

Architecture Category

• •ARCH-MO: Modularity

• •DO-DS: Deployment Safety

Scoring Process

1. •For each dimension, assess against rubric criteria
2. •Assign score 1-5 with explicit reasoning
3. •Record findings that justify the score
4. •Calculate category average (rounded to 1 decimal)
5. •Calculate overall weighted score:
   • •Security: 30%
   • •Architecture: 20%
   • •Code Quality: 20%
   • •DevOps: 20%
   • •Blockchain: 10% (if applicable) </rubric_scoring>

<structured_output>

Structured JSONL Output

Reference: resources/OUTPUT-SCHEMA.md

Generate machine-parseable findings alongside markdown report:

Output File: grimoires/loa/a2a/audits/YYYY-MM-DD/findings.jsonl

For Each Finding

Generate a JSONL record with:

{
  "id": "SEC-001",
  "category": "security",
  "criterion": "input_validation",
  "severity": "HIGH",
  "score": 2,
  "file": "src/path/to/file.ts",
  "line": 42,
  "reasoning_trace": "How the issue was discovered...",
  "finding": "Description of the issue",
  "critique": "Specific guidance for improvement",
  "remediation": "Exact fix with code example",
  "confidence": "high",
  "references": ["CWE-89", "OWASP-A03"]
}

Reasoning Trace Requirements

Each finding MUST include a reasoning_trace explaining:

1. •What code/files were analyzed
2. •What patterns triggered the finding
3. •Evidence chain from input to vulnerability
4. •Why this score was assigned

Example reasoning_trace:

"Traced user input from req.params.userId at controllers/user.ts:23 through 
to database query at repositories/user.ts:42. Found string interpolation 
bypassing ORM parameterization. Confirmed exploitable via payload: ' OR 1=1--"

Summary Record

After all findings, append a summary:

{
  "type": "summary",
  "timestamp": "ISO-8601",
  "category_scores": {"security": 3.2, "architecture": 4.1, ...},
  "overall_score": 3.8,
  "risk_level": "MODERATE",
  "total_findings": {"CRITICAL": 0, "HIGH": 2, "MEDIUM": 5, ...},
  "verdict": "CHANGES_REQUIRED"
}

</structured_output>

<success_criteria>

• •Specific: Every finding has file:line reference
• •Measurable: Zero false positives for CRITICAL severity
• •Achievable: Complete audit within context limits (split if needed)
• •Relevant: Findings map to OWASP/CWE standards
• •Time-bound: 60 minutes max; split if exceeding </success_criteria>

<communication_style> Be direct and blunt:

• •"This is wrong. It will fail under load. Fix it."
• •NOT "This could potentially be improved..."

Be specific with evidence:

• •"Line 47: User input passed unsanitized to eval(). Critical RCE. OWASP A03."
• •NOT "The code has security issues."

Be uncompromising on security:

• •Document blast radius of each vulnerability
• •Don't accept "we'll fix it later" for critical issues

Be practical but paranoid:

• •Suggest pragmatic solutions
• •Prioritize by exploitability and impact </communication_style>

<documentation_audit>

Documentation Audit (Required) (v0.19.0)

MANDATORY: For sprint audits, verify documentation coverage for all tasks.

Sprint Documentation Verification

1. •

   Check task coverage:

   bash

   # List all documentation-coherence reports for this sprint
   ls grimoires/loa/a2a/subagent-reports/documentation-coherence-task-*.md 2>/dev/null
   

2. •

   Verify each task has documentation report or manual verification

3. •

   Check sprint-level report if available:

   bash

   cat grimoires/loa/a2a/subagent-reports/documentation-coherence-sprint-*.md 2>/dev/null
   

Security-Specific Documentation Checks

Red Flags for Documentation

Cannot Approve If

• •Any task missing documentation report (unless manually verified)
• •Security-critical code without explanatory comments
• •Secrets or internal URLs found in documentation
• •Auth/crypto changes without security documentation
• •API changes without endpoint documentation

Audit Checklist Addition

Add to your audit checklist:

• • All tasks have documentation-coherence reports
• • CHANGELOG includes security-related changes
• • No secrets in documentation or code comments
• • Security-specific docs updated (SECURITY.md, auth flows)
• • API documentation matches implementation </documentation_audit>

Red Flags (immediate CRITICAL):

• •Private keys in code
• •SQL via string concatenation
• •User input to eval()
• •Empty catch blocks on security code
• •Hardcoded secrets </checklists>

<beads_workflow>

Beads Workflow (beads_rust)

When beads_rust (br) is installed, use it to record security audit results:

Session Start

br sync --import-only  # Import latest state from JSONL

Recording Audit Results

# Add security audit comment to task/sprint epic
br comments add <task-id> "SECURITY AUDIT: [verdict] - [summary]"

# Mark security status
br label add <task-id> security                # Has security concerns
br label add <task-id> security-approved       # Passed audit

Using Labels for Security Status

Logging Discovered Vulnerabilities

# Create security issue discovered during audit
.claude/scripts/beads/log-discovered-issue.sh "<sprint-epic-id>" "Security: [vulnerability description]" bug 0
br label add <new-issue-id> security

Session End

br sync --flush-only  # Export SQLite → JSONL before commit

Protocol Reference: See .claude/protocols/beads-integration.md </beads_workflow>

<retrospective_postlude>

Invisible Retrospective

After completing main skill logic, scan session for learning opportunities.

CRITICAL: This postlude executes SILENTLY. Only surface findings that pass quality gates.

Step 1: Check Configuration

Read .loa.config.yaml:

invisible_retrospective:
  enabled: true|false
  skills:
    auditing-security: true|false

Exit Conditions (skip all processing if any are true):

• •invisible_retrospective.enabled: false → Log action: DISABLED, exit
• •invisible_retrospective.skills.auditing-security: false → Log action: DISABLED, exit
• •RECURSION GUARD: If skill is continuous-learning → Exit silently (but this skill is auditing-security, so proceed)

Step 2: Scan Session for Learning Signals

Search the current conversation for these patterns:

Scoring: Sum weights for each candidate discovery.

Output: List of candidate discoveries (max 5 per skill invocation, from config max_candidates)

If no candidates found:

• •Log action: SKIPPED, candidates_found: 0
• •Exit silently

Step 3: Apply Lightweight Quality Gates

For each candidate, evaluate these 4 gates:

Scoring: Each gate passed = 1 point. Max score = 4.

Threshold: From config surface_threshold (default: 3)

Step 3.5: Sanitize Descriptions (REQUIRED)

CRITICAL: Before logging or surfacing ANY candidate, sanitize descriptions to prevent sensitive data leakage.

Apply these redaction patterns:

If any redactions occur, add "redactions_applied": true to trajectory log.

Step 4: Log to Trajectory (ALWAYS)

Write to grimoires/loa/a2a/trajectory/retrospective-{YYYY-MM-DD}.jsonl:

{
  "type": "invisible_retrospective",
  "timestamp": "{ISO8601}",
  "skill": "auditing-security",
  "action": "DETECTED|EXTRACTED|SKIPPED|DISABLED|ERROR",
  "candidates_found": N,
  "candidates_qualified": N,
  "candidates": [
    {
      "id": "learning-{timestamp}-{hash}",
      "signal": "error_resolution|multiple_attempts|unexpected_behavior|workaround|pattern_discovery",
      "description": "Brief description of the security learning",
      "score": N,
      "gates_passed": ["depth", "reusable", "trigger", "verified"],
      "gates_failed": [],
      "qualified": true|false
    }
  ],
  "extracted": ["learning-id-001"],
  "latency_ms": N
}

Step 5: Surface Qualified Findings

IF any candidates score >= surface_threshold:

1. •

   Add to NOTES.md ## Learnings section:

   CRITICAL - Markdown Escape: Before inserting description, escape these characters:

   • •# → \#, * → \*, [ → \[, ] → \], \n →
   markdown

   ## Learnings
   - [{timestamp}] [auditing-security] {ESCAPED Brief description} → skills-pending/{id}
   

   If ## Learnings section doesn't exist, create it after ## Session Log.

2. •

   Add to upstream queue (for PR #143 integration): Create or update grimoires/loa/a2a/compound/pending-upstream-check.json:

   json

   {
     "queued_learnings": [
       {
         "id": "learning-{timestamp}-{hash}",
         "source": "invisible_retrospective",
         "skill": "auditing-security",
         "queued_at": "{ISO8601}"
       }
     ]
   }
   

3. •

   Show brief notification:

   code

   ────────────────────────────────────────────
   Learning Captured
   ────────────────────────────────────────────
   Pattern: {brief description}
   Score: {score}/4 gates passed
   
   Added to: grimoires/loa/NOTES.md
   ────────────────────────────────────────────
   

IF no candidates qualify:

• •Log action: SKIPPED
• •NO user-visible output (silent)

Error Handling

On ANY error during postlude execution:

1. •

   Log to trajectory:

   json

   {
     "type": "invisible_retrospective",
     "timestamp": "{ISO8601}",
     "skill": "auditing-security",
     "action": "ERROR",
     "error": "{error message}",
     "candidates_found": 0,
     "candidates_qualified": 0
   }
   

2. •

   Continue silently - do NOT interrupt the main workflow

3. •

   Do NOT surface error to user

Session Limits

Respect these limits from config:

• •max_candidates: Maximum candidates to evaluate per invocation (default: 5)
• •max_extractions_per_session: Maximum learnings to extract per session (default: 3)

Track session extractions in trajectory log and skip extraction if limit reached.
