Best practices for git usage, commits, and workflow
Optimizing arithmetic circuits / constraint systems (R1CS, PLONKish, AIR) for zero-knowledge proofs — minimizing multiplication constraints, rows, witnesses, and gate degree. Use when reducing constraint/witness counts, designing or golfing R1CS/PLONK/AIR gadgets (boolean ops, adders, range checks, hashes like SHA-256/Keccak/Poseidon), doing foreign-field/non-native or CRT/RNS arithmetic, choosing lookups vs arithmetic, or using SMT (cvc5) and SageMath (Gröbner basis) to synthesize, verify, and certify constraint encodings.
Writing, proving, and debugging Lean 4 + Mathlib. Use when proving theorems, filling `sorry`s, formalizing math, fixing broken proofs, or setting up a Lean project. Covers the cached-Mathlib setup and a plan-first proving workflow.
Performance-guided Rust optimization using benchmarks, sampling profilers, and agent-readable profiling artifacts. Use when optimizing Rust throughput, latency, CPU time, allocations, code size, compile/runtime hot paths, Criterion benchmarks, hyperfine measurements, Linux perf, macOS xctrace/Instruments, samply, flamegraphs, heap profilers, cargo-bloat, cargo-llvm-lines, or cargo-asm.

Pipe the prompt on stdin; use exec for non-interactive output:
echo "<prompt>" | codex exec --skip-git-repo-check
--skip-git-repo-check lets it run outside a git repo. Drop it when invoking inside a repo where codex should see git context.
-m <model> — override model (e.g. gpt-5.1-codex).-C <dir> — set working directory.-s read-only — sandbox mode (read-only, workspace-write, danger-full-access).--dangerously-bypass-approvals-and-sandbox — fully autonomous; only inside an already-sandboxed env.-i <file> — attach image(s).--output-schema <file.json> — constrain final response to a JSON schema.Heredoc for multi-line prompts:
codex exec --skip-git-repo-check <<'EOF'
Review foo.rs for race conditions.
Report findings as a bullet list.
EOF
From a file:
codex exec --skip-git-repo-check < prompt.txt
Inside a repo, read-only second opinion:
echo "Audit auth.rs for input validation gaps." | codex exec -s read-only
run_in_background and read output later.
