Workaround for write_file failures caused by special characters (apostrophes, backticks, template literals) using a Python heredoc script, with mandatory post-write verification via read_file and cleanup of /tmp helper scripts.
Workaround for write_file failures caused by special characters (apostrophes, backticks, template literals) using a Python heredoc script, plus a reliable TypeScript type-checking step that filters output to only the newly-written files to avoid being misled by pre-existing errors.
Use shell Python heredoc as fallback when code sandbox fails
Debug Python code execution failures by capturing partial traces, isolating failing functions, and incrementally verifying outputs
Debug Python PDF generation errors by using unbuffered output and stderr inspection to reveal actual tracebacks
Debug Python script execution failures by capturing full tracebacks and verifying working directory
Debug Python scripts with proper error surfacing and working directory verification
Debug Python script execution failures by capturing full output with exit codes and verifying working directory before file operations
Systematic Python debugging workflow for spreadsheet tasks to isolate environment issues from script logic
Explain, implement, or debug TqSdk Python workflows for wait_update or is_changing update loops, market data retrieval, historical download, account type selection, funds or positions or orders or trades, field meanings, order placement or cancelation, target-position tools, simulation, backtest, and common TqSdk errors. Use when a request mentions TqSdk, TqApi, TqAuth, TqAccount, TqKq, TqKqStock, TqSim, TqSimStock, TqMultiAccount, TqBacktest, TargetPosTask, TargetPosScheduler, DataDownloader, market data, K-line, tick, historical data, positions, trades, orders, account data, order placement, cancelation, position adjustment, field meanings, wait_update, debugging, 行情, K线, 历史数据, 持仓, 成交, 委托, 账户, 下单, 撤单, 调仓, 字段含义, or 报错.
Use when the user asks to "update libtmux", "bump libtmux", "upgrade libtmux dependency", "check for new libtmux version", or when investigating whether tmuxp needs a libtmux update. Guides the full workflow: studying upstream changes, updating the dependency, migrating code and tests, and producing separate atomic commits with rich messages.
Detects timing side-channel vulnerabilities in cryptographic code. Use when implementing or reviewing crypto code, encountering division on secrets, secret-dependent branches, or constant-time programming questions in C, C++, Go, Rust, Swift, Java, Kotlin, C#, PHP, JavaScript, TypeScript, Python, or Ruby.
Creates devcontainers with Claude Code, language-specific tooling (Python/Node/Rust/Go), and persistent volumes. Use when adding devcontainer support to a project, setting up isolated development environments, or configuring sandboxed Claude Code workspaces.
Configures Python projects with modern tooling (uv, ruff, ty). Use when creating projects, writing standalone scripts, or migrating from pip/Poetry/mypy/black.
Builds and queries multi-language source code graphs for security analysis. Includes pre-analysis passes for blast radius, taint propagation, privilege boundaries, and entry point enumeration. Use when analyzing call paths, mapping attack surface, finding complexity hotspots, enumerating entry points, tracing taint propagation, measuring blast radius, or building a code graph for audit prioritization. Supports 16 languages including Solidity, Cairo, Circom, Rust, Go, Python, C/C++, TypeScript.
Run profile-driven bottleneck optimization across Apache Fory implementations (Java, C++, Python/Cython, Go, Rust, Swift, C#, JavaScript/TypeScript, Dart, Kotlin, Scala). Use when improving serialize/deserialize throughput or latency, recovering regressions against a reference commit, diagnosing flamegraphs, fixing perf-related CI failures, or porting proven optimizations across languages without protocol or API regressions.
