refactor: agents and skills move to a client-neutral source that renders per client
`.claude/agents/` was the source of truth, which made every role Claude-Code shaped. Adding a second client meant rewriting each role in that client's syntax and maintaining both copies — the drift this scaffold exists to prevent, one layer up. Roles and skills now live under `.agents/` and render into each registered client. `.claude/agents/`, `.claude/skills/` and `.codex/agents/` are generated; `scripts/sync-agent-integrations.py --check` fails on drift and belongs in CI. The role metadata is portable rather than vendor-named: `reasoning_tier` (deep/balanced/fast/vision), `capabilities`, `mutation`, `invocation`, and an optional `preload_skills`. A client manifest maps those to native syntax and must declare what it cannot express — `codex.yaml` declares `tier_policy: unsupported` and its adapters say so in the file, rather than the tier silently evaporating and leaving the repository to believe it was enforced. The port is behaviour-preserving where it should be and a fix where it should not. Every instruction body is byte-identical — the whole diff to `.claude/agents/` is 18 added lines and zero deletions. What changed is frontmatter that was missing: - four agents (`code-reviewer`, `tdd-guardian`, `dependency-audit`, `pr-creator`) declared no `tools:` and therefore inherited the ENTIRE tool pool, so three review-only agents could edit and write the code they were reviewing. All eight now declare capabilities explicitly. - the six read-only roles gain a non-editing permission mode, so the constraint is enforced by the client rather than by the prompt asking nicely. - `mutation` is now explicit, which records the two roles that genuinely need to write: `pr-creator` (external-write — it pushes a branch and opens a PR) and `dependency-audit` (workspace-write — package managers rewrite lockfiles). `pr-creator` keeps `shell` because opening a PR needs it, but it is now the only agent here with a write mutation and a declared reason for it, instead of one of four with unlimited access by omission.

## Scan Categories
|
||||
|
||||
### 1. Secrets Detection
|
||||
|
||||
**Patterns to detect:**
|
||||
```regex
|
||||
# AWS Keys
|
||||
AKIA[0-9A-Z]{16}
|
||||
aws_secret_access_key\s*=\s*['\"][^'\"]+['\"]
|
||||
|
||||
# API Keys
|
||||
api[_-]?key\s*[:=]\s*['\"][^'\"]{16,}['\"]
|
||||
secret[_-]?key\s*[:=]\s*['\"][^'\"]+['\"]
|
||||
|
||||
# Tokens
|
||||
ghp_[a-zA-Z0-9]{36} # GitHub Personal Access Token
|
||||
sk-[a-zA-Z0-9]{48} # OpenAI API Key
|
||||
xox[baprs]-[0-9a-zA-Z-]+ # Slack Token
|
||||
|
||||
# Database URLs
|
||||
(postgres|mysql|mongodb)(\+\w+)?://[^:]+:[^@]+@
|
||||
|
||||
# Private Keys
|
||||
-----BEGIN (RSA |EC |OPENSSH )?PRIVATE KEY-----
|
||||
```
|
||||
|
||||
**Commands:**
|
||||
```bash
|
||||
# Search for potential secrets
|
||||
grep -rniE "(password|secret|api.?key|token)\s*[:=]\s*['\"][^'\"]+['\"]" src/
|
||||
grep -rn "AKIA" src/
|
||||
grep -rn "ghp_" src/
|
||||
```
|
||||
|
||||
### 2. SQL Injection
|
||||
|
||||
**Vulnerable patterns:**
|
||||
```python
|
||||
# BAD - String formatting
|
||||
query = f"SELECT * FROM users WHERE id = {user_id}"
|
||||
cursor.execute(f"DELETE FROM items WHERE id = '{item_id}'")
|
||||
|
||||
# BAD - String concatenation
|
||||
query = "SELECT * FROM users WHERE email = '" + email + "'"
|
||||
```
|
||||
|
||||
**Secure patterns:**
|
||||
```python
|
||||
# GOOD - Parameterized queries
|
||||
cursor.execute("SELECT * FROM users WHERE id = %s", (user_id,))
|
||||
|
||||
# GOOD - ORM
|
||||
User.query.filter_by(id=user_id).first()
|
||||
|
||||
# GOOD - SQLAlchemy
|
||||
stmt = select(User).where(User.id == user_id)
|
||||
```
|
||||
|
||||
### 3. XSS (Cross-Site Scripting)
|
||||
|
||||
**Vulnerable patterns:**
|
||||
```typescript
|
||||
// BAD - dangerouslySetInnerHTML without sanitization
|
||||
<div dangerouslySetInnerHTML={{ __html: userInput }} />
|
||||
|
||||
// BAD - Direct DOM manipulation
|
||||
element.innerHTML = userContent;
|
||||
```
|
||||
|
||||
**Secure patterns:**
|
||||
```typescript
|
||||
// GOOD - Use text content
|
||||
element.textContent = userContent;
|
||||
|
||||
// GOOD - Sanitize if HTML is required
|
||||
import DOMPurify from 'dompurify';
|
||||
<div dangerouslySetInnerHTML={{ __html: DOMPurify.sanitize(content) }} />
|
||||
```
|
||||
|
||||
### 4. Path Traversal
|
||||
|
||||
**Vulnerable patterns:**
|
||||
```python
|
||||
# BAD - User input in file path
|
||||
file_path = f"/uploads/{user_filename}"
|
||||
with open(file_path, 'r') as f:
|
||||
return f.read()
|
||||
```
|
||||
|
||||
**Secure patterns:**
|
||||
```python
|
||||
# GOOD - Validate and sanitize
|
||||
import os
|
||||
|
||||
def safe_file_read(filename: str, base_dir: str) -> str:
|
||||
# Remove path traversal attempts
|
||||
safe_name = os.path.basename(filename)
|
||||
full_path = os.path.join(base_dir, safe_name)
|
||||
|
||||
# Verify path is within allowed directory
|
||||
if not os.path.realpath(full_path).startswith(os.path.realpath(base_dir)):
|
||||
raise ValueError("Invalid file path")
|
||||
|
||||
with open(full_path, 'r') as f:
|
||||
return f.read()
|
||||
```
|
||||
|
||||
### 5. Insecure Dependencies
|
||||
|
||||
**Commands:**
|
||||
```bash
|
||||
# Python
|
||||
pip-audit
|
||||
safety check
|
||||
|
||||
# Node.js
|
||||
npm audit
|
||||
npx audit-ci --critical
|
||||
|
||||
# Rust
|
||||
cargo audit
|
||||
```
|
||||
|
||||
### 6. Hardcoded Configuration
|
||||
|
||||
**Vulnerable patterns:**
|
||||
```python
|
||||
# BAD - Hardcoded values
|
||||
DATABASE_URL = "postgresql://user:password@localhost/db"
|
||||
API_ENDPOINT = "https://api.production.com"
|
||||
DEBUG = True
|
||||
```
|
||||
|
||||
**Secure patterns:**
|
||||
```python
|
||||
# GOOD - Environment variables
|
||||
import os
|
||||
from pydantic_settings import BaseSettings
|
||||
|
||||
class Settings(BaseSettings):
|
||||
database_url: str
|
||||
api_endpoint: str
|
||||
debug: bool = False
|
||||
|
||||
settings = Settings()
|
||||
```

### Critical Issues
|
||||
|
||||
#### [CRIT-001] Hardcoded AWS Credentials
|
||||
**File:** `src/config.py:42`
|
||||
**Type:** Secrets Exposure
|
||||
|
||||
**Vulnerable Code:**
|
||||
```python
|
||||
AWS_SECRET_KEY = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
|
||||
```
|
||||
|
||||
**Remediation:**
|
||||
1. Remove the secret from code immediately
|
||||
2. Rotate the exposed credential
|
||||
3. Use environment variables or AWS Secrets Manager:
|
||||
```python
|
||||
AWS_SECRET_KEY = os.environ.get("AWS_SECRET_ACCESS_KEY")
|
||||
```
