Use **bash** (with optional background mode) for all coding agent work. Simple and effective.

Timing attacks exploit variations in execution time to extract secret information from cryptographic implementations. Unlike cryptanalysis that targets theoretical weaknesses, timing attacks leverage implementation flaws - and they can affect any cryptographic code.

Coverage analysis is essential for understanding which parts of your code are exercised during fuzzing. It helps identify fuzzing blockers like magic value checks and tracks the effectiveness of harness improvements over time.

Crow gives your AI agent a wallet to pay for APIs and services autonomously — within spending rules set by the wallet owner.

Differential analysis to verify commits address security findings without introducing bugs.

Goal: reorder a previous Foodora order safely (preview first; confirm only on explicit user “yes/confirm/place the order”). Hard safety rules - Never run `ordercli foodora reorder ... --confirm` unless user explicitly confirms placing the order. - Prefer preview-only steps first; show what will happen; ask for confirmation. - If user is unsure: stop at preview and ask questions. Setup (once) - Country: `ordercli foodora countries` → `ordercli foodora config set --country AT` - Login (password...

A fuzzing dictionary provides domain-specific tokens to guide the fuzzer toward interesting inputs. Instead of purely random mutations, the fuzzer incorporates known keywords, magic numbers, protocol commands, and format-specific strings that are more likely to reach deeper code paths in parsers, protocol handlers, and file format processors.

Codebases often contain anti-fuzzing patterns that prevent effective coverage. Checksums, global state (like time-seeded PRNGs), and validation checks can block the fuzzer from exploring deeper code paths. This technique shows how to patch your System Under Test (SUT) to bypass these obstacles during fuzzing while preserving production behavior.

Quick start - `gemini "Answer this question..."` - `gemini --model <name> "Prompt..."` - `gemini --output-format json "Return JSON"` Extensions - List: `gemini --list-extensions` - Manage: `gemini extensions <command>` Notes - If auth is required, run `gemini` once interactively and follow the login flow. - Avoid `--yolo` for safety.

A fuzzing harness is the entrypoint function that receives random data from the fuzzer and routes it to your system under test (SUT). The quality of your harness directly determines which code paths get exercised and whether critical bugs are found. A poorly written harness can miss entire subsystems or produce non-reproducible crashes.

Assess and harden the host running Otto, then align it to a user-defined risk tolerance without breaking access. Use Otto security tooling as a first-class signal, but treat OS hardening as a separate, explicit set of steps.
