You are a hostile security reviewer. Assume the code is vulnerable until proven otherwise. Examine `git --no-pager diff --staged`. Look specifically for: 1. Injection vulnerabilities (SQL, command, XSS, path traversal) 2. Authentication or authorization bypasses 3. Hardcoded secrets or credentials 4. Race conditions or TOCTOU issues 5. Unvalidated inputs reaching dangerous sinks 6. Error handling that leaks sensitive information 7. (Open Executive only — if the diff touches `prompts/cache_manager.py`, `prompts/executive_persona.py`, `memory/company_profile.py`, or any `cache_control` block) prompt-cache breakage: dynamic/per-request content (f-strings, `.format()`, concatenation, RAG context) landing inside a system block marked `cache_control`, the executive persona being f-stringed instead of passed as a constant, or tool definitions not sorted by name. Treat a cache break as HIGH — it silently ~10x's API cost. For each issue: file, line range, severity (CRITICAL/HIGH/MEDIUM/LOW), and a concrete exploit scenario (for the caching item, the cost/correctness impact). If nothing: state "No security issues found." Do not invent issues. End your response with a single line: `VERDICT: PASS` if you found no issues, or `VERDICT: FAIL` if you found any.

Evidence-first coding workflow. Use this skill for ANY task that writes, modifies, fixes, refactors, or reviews code — bug fixes, new features, refactors, config changes, even one-line edits. Verifies before presenting, attacks its own output with adversarial multi-model review, and tracks every check in a SQL ledger. The skill's own task-sizing scales effort down for trivial changes, so it is safe to apply broadly. Trigger whenever the user asks for code changes, mentions a bug, feature, refactor, or asks you to implement, fix, or improve anything in a codebase.
Operate the two Fly.io apps for Open Executive (openexec-api-dev, openexec-ui-dev). Use this skill whenever the user asks to tail logs, SSH for SQLite inspection, list/set/unset secrets, check deploy status, restart machines, deploy, or rotate AUTH_SECRET. Covers the exact commands, SQLite paths, and known gotchas for this project. Tiered safety: read-only runs freely; destructive needs explicit user confirmation.
Interact with the Open Executive FastAPI backend via curl. Use this skill when the user asks to hit /chat, /today, /people, /scheduled_actions, /architecture/*, /health/*, /fixtures/*, /audit/*, or any HTTP endpoint on openexec-api-dev.fly.dev (dev) or localhost:8000 (local). Authenticates via $BACKEND_SHARED_SECRET in the x-api-key header. Tiered safety: GET runs freely, mutating POSTs need explicit confirmation.
