Context Security Layer

Context Guard now protects both your work state (compaction recovery) and your context content (security scanning).

New: 4 Detection Engines (Pure Bash)

Engine What it detects
Injection Scanner Instruction override, identity reassignment, tag injection, jailbreak (15+ patterns)
Leakage Scanner API keys, AWS credentials, private keys, JWT, GitHub/GitLab tokens (13+ patterns)
File Guard Sensitive file reads: .env, .pem, SSH keys, credentials (20+ patterns)
Manipulation Scanner Fake system tags, hidden instructions, zero-width characters

New: Security Hooks

  • PreToolUse — scans tool inputs before execution (can block or warn)
  • PostToolUse — scans tool outputs after execution (warns via systemMessage)

3 Security Modes

Mode Behavior
warn (default) Alerts without blocking — safe for daily use
block Prevents dangerous tool calls
log Silent audit trail

New Components

  • context-security-lib.sh — scanning library (4 engines, ~300 lines)
  • security-pre-tool.sh / security-post-tool.sh — hook entry points
  • config/security-config.sh — feature toggles, mode selection
  • config/allowlist.txt — suppress known-safe patterns
  • /cg-security-status — security dashboard skill
  • /cg-security-config — manage settings skill
  • context-security-rules.md — hookify protection rules

Stats

  • 17 files changed, 1358 insertions
