# Windsurf-Hooker: Enforcement Gaps Analysis ## Current Status Windsurf-hooker has 3 primary pre-write enforcement hooks: 1. ✅ `pre_write_code_escape_detection.py` - Blocks subprocess, socket, etc. 2. ✅ `pre_write_code_policy.py` - Enforces prohibited patterns, logic preservation 3. ⚠️ `pre_write_diff_quality.py` - Warns but doesn't enforce (except in SHIP mode) ## Intended Purpose vs Reality ### Intent (from AGENTS.md) Windsurf-hooker should enforce: - ✅ Comprehensive commentary throughout code - ✅ Everything debuggable by default - ❌ **No TODOs, FIXMEs** - ❌ **No simplified/placeholder code** - ❌ **No mock data** - ❌ **No stub code** - ✅ Real, working, 100% correct code ### What's Actually Enforced | Rule | Enforcement | Gap | |------|-------------|-----| | No TODOs/FIXMEs | ✅ Checked in policy | ⚠️ Only if in `prohibited_patterns` | | No mock data | ✅ Checked in escape detection | ✅ OK | | No stub code | ✅ Checked in policy | ⚠️ Only if patterns match | | No simplified code | ⚠️ Partial (logic preservation) | ❌ Doesn't check code quality/depth | | Comprehensive comments | ❌ **NOT ENFORCED** | 🔴 CRITICAL GAP | | Debuggability | ❌ **NOT ENFORCED** | 🔴 CRITICAL GAP | | 100% complete code | ❌ **NOT ENFORCED** | 🔴 CRITICAL GAP | --- ## Critical Gaps ### Gap 1: No Comment/Documentation Enforcement **Missing:** Validation that code has sufficient, high-quality comments. Current state: `pre_write_diff_quality.py` only warns about generated code lacking comments in SHIP mode. **Should enforce:** - Functions must have docstrings - Complex logic must have inline comments explaining WHY (not WHAT) - Public APIs must document parameters, return values, exceptions - No code without accompanying explanation ### Gap 2: No Completeness Check **Missing:** Validation that code is 100% implemented (no TODOs masked as comments). Current state: Regex checks `prohibited_patterns` but: - May not catch all variants (e.g., `# TODO: `, `// FIXME:`, `/* todo */`) - Doesn't catch semantic TODOs like `pass`, `return None`, `raise NotImplementedError` **Should enforce:** - No TODO, FIXME, XXX comments (any case variant) - No `pass` statements (except empty except blocks) - No `raise NotImplementedError` or `raise TODO` - No placeholder returns like `return None` or `return {}` - All control paths must lead to real code ### Gap 3: No Code Quality/Depth Enforcement **Missing:** Validation that written code is actually good/thoughtful. Current state: No checks for: - Overly simplified implementations - Missing error handling - Hardcoded values instead of parameterization - Lack of type annotations (Python/TypeScript) - No validation of business logic correctness ### Gap 4: No Debuggability Enforcement **Missing:** Validation that code is debuggable and traceable. **Should enforce:** - Meaningful variable names (not `x`, `temp`, `data`) - Functions are reasonably sized (< 100 lines typical) - Error messages are informative (not generic) - State changes are trackable - No silent failures or swallowed exceptions --- ## Comparison: ATLAS-GATE vs Windsurf-Hooker ### ATLAS-GATE (server-side, post-write) From `write_file.js` GATE 4: ```javascript // GATE 4: ENTERPRISE CODE ENFORCEMENT (OBJECTIVE 3) // HARD BLOCK: No stubs, mocks, placeholders, TODOs, or non-enterprise code detectStubs(contentToWrite, normalizedPath); ``` Also in GATE 2.5 (write-time policy): ```javascript // GATE 2.5: WRITE-TIME POLICY ENGINE (FAIL-CLOSED) // - Universal denylist (TODOs, empty catches, debug bypasses) // - Language-specific rules (Rust unwrap, TS any, Python randomness) ``` ### Windsurf-Hooker (client-side, pre-write) Supposed to catch the same issues **before** reaching ATLAS-GATE, but: - Less comprehensive - More warnings than blocks - Doesn't enforce code quality depth --- ## Proposed New Hooks ### 1. `pre_write_comprehensive_comments.py` (NEW) **Purpose:** Enforce detailed, meaningful commentary. ```python # Checks: # - Every function/class has a docstring # - Complex logic has inline comments (min ratio) # - Comments explain WHY not WHAT # - No empty docstrings or one-liners for complex code # - Comments are accurate to code ``` ### 2. `pre_write_completeness.py` (NEW) **Purpose:** Enforce 100% implementation (no TODOs, no stubs). ```python # Checks: # - No TODO, FIXME, XXX, HACK (any case) # - No pass statements (except catch-all except blocks) # - No raise NotImplementedError # - No placeholder returns (None, {}, [], etc. as full function) # - All control paths have real code # - No unimplemented features ``` **Patterns to block:** ```python r"\b(TODO|FIXME|XXX|HACK|BUG|NOTE|TEMP)\b" # Comments r"^\s*pass\s*$" # pass keyword r"raise\s+(NotImplementedError|TODO)" # Stub raises r"^\s*return\s*$" # Empty return r"^\s*return\s+(None|{}|\[\])\s*$" # Placeholder return r"^\s*\.\.\.\s*$" # Ellipsis placeholder r"^\s*unimplemented" # Rust unimplemented ``` ### 3. `pre_write_code_quality.py` (NEW - Enhanced) **Purpose:** Enforce thoughtful, production-grade code. ```python # Checks: # - Function length (flag >100 lines) # - Variable naming (no x, temp, data, val, etc.) # - Error handling completeness # - Type annotations present (Python/TS) # - Hard-coded values are parameterized # - No debug/test code in production # - No commented-out code (use git history) ``` ### 4. `pre_write_debuggability.py` (NEW) **Purpose:** Ensure code is debuggable and traceable. ```python # Checks: # - Meaningful error messages (not "Error" or "Failed") # - No silent failures (unhandled exceptions logged) # - Exception context preserved # - Variable names convey intent # - No magic numbers without explanation # - State changes have audit trails ``` --- ## Implementation Priority ### Phase 1 (CRITICAL) 1. `pre_write_completeness.py` - Block TODOs, stubs, incomplete code 2. Enhance `pre_write_code_policy.py` - Tighter prohibited pattern matching ### Phase 2 (HIGH) 3. `pre_write_comprehensive_comments.py` - Enforce documentation standards 4. `pre_write_code_quality.py` - Enforce thoughtful implementations ### Phase 3 (MEDIUM) 5. `pre_write_debuggability.py` - Enforce debuggability standards --- ## Current Policy File Status From `/windsurf-hooker/windsurf/policy/policy.json`: ```json "prohibited_patterns": { "placeholders": ["TODO", "FIXME", "XXX", "pass", "unimplemented", "stub"], "mock_artifacts": ["mock data", "fake data", "demo data", "hardcoded test"], "assumptions_and_hacks": ["assume", "temporary", "for now", "hack", "workaround"], "escape_attempts": [ "os\\.system", "subprocess", "exec\\(", "eval\\(", "\\bopen\\(" ] } ``` ### Problems: 1. Pattern matching is loose (e.g., `"TODO"` matches `# This is about todos in general`) 2. No enforcement of comment quality 3. No check for function/class documentation 4. Doesn't catch masked TODOs (different case, different wording) 5. No semantic checking (e.g., empty `return` statements) --- ## Enforcement Architecture ``` ┌─────────────────────────────────────────┐ │ Windsurf IDE │ │ (User writes code) │ └──────────────────┬──────────────────────┘ │ ┌──────────▼──────────┐ │ PRE-WRITE HOOKS │ (Enforced by windsurf-hooker) │ │ │ 1. pre_user_prompt_gate │ 2. pre_intent_classification │ 3. pre_plan_resolution │ ↓↓↓ CODE QUALITY GATES ↓↓↓ │ 4. pre_mcp_tool_use_atlas_gate │ 5. pre_write_code_escape_detection ✅ │ 6. pre_write_code_policy ✅ │ 7. pre_write_comprehensive_comments ❌ MISSING │ 8. pre_write_completeness ❌ MISSING │ 9. pre_write_code_quality ❌ MISSING │ 10. pre_write_debuggability ❌ MISSING │ 11. pre_write_diff_quality ⚠️ (warnings only) │ ↓↓↓ EXECUTION GATES ↓↓↓ │ 12. pre_filesystem_write │ 13. pre_filesystem_write_atlas_enforcement │ 14. pre_run_command_* └──────────────────┬─────────────────────┘ │ ┌──────────────────▼──────────────┐ │ ATLAS-GATE MCP SERVER │ (Server-side enforcement) │ │ │ GATE 2: Plan enforcement │ │ GATE 2.5: Write-time policy │ │ GATE 4: Enterprise enforcement │ │ GATE 4.5: Preflight validation │ │ GATE 5: Audit logging │ └─────────────────────────────────┘ ``` --- ## Example: How Completeness Gap Affects System ### Scenario: Developer writes incomplete code ```javascript // User writes: function processUser(user) { // TODO: validate user object // TODO: sanitize inputs console.log("Processing", user.name); // TODO: implement actual processing return; } ``` ### What Happens Now: 1. **Windsurf hook `pre_write_code_policy`** - Looks for "TODO" in `prohibited_patterns` - If configured, might catch it ✅ - But could miss variants like "FIXME:", "TO-DO", etc. - Pattern matching is fragile ⚠️ 2. **ATLAS-GATE server `detectStubs()`** - Catches it after transmission ✅ - But it's wasted bandwidth - Windsurf IDE should have caught it first ### What Should Happen: 1. **Windsurf hook `pre_write_completeness`** - Comprehensive check - Catches "TODO" and all variants - Rejects immediately ✅ - Never reaches server --- ## Recommendation **Implement Phase 1 + Phase 2 immediately:** 1. Create `pre_write_completeness.py` - Mandatory completeness validation 2. Create `pre_write_comprehensive_comments.py` - Mandatory documentation validation 3. Update policy patterns to be more precise 4. Integrate into windsurf-hooker hook chain This would **enforce the entire intended standard BEFORE ATLAS-GATE**, reducing: - Network round-trips - Rejection rate - Wasted computation - IDE friction --- ## Supporting Evidence From `write_file.js`: ```javascript // GATE 4: ENTERPRISE CODE ENFORCEMENT (OBJECTIVE 3) // HARD BLOCK: No stubs, mocks, placeholders, TODOs, or non-enterprise code detectStubs(contentToWrite, normalizedPath); ``` This gate exists at the server. Windsurf-hooker should implement the same gate (or tighter) at the client. --- ## Status - **Current:** Windsurf-hooker covers ~60% of enforcement - **Needed:** 4 additional hooks to reach 95%+ coverage - **Timeline:** Can be implemented in phases - **Impact:** Shift enforcement left (IDE-side) vs late (server-side)
