What is st-develop?
The st-develop skill is a specialized toolset designed for engineers working on the State Threads (ST) library, which serves as the core concurrency model for the SRS (Simple Realtime Server). This skill facilitates deep-level manipulation of C coroutines, enabling agents to handle everything from high-level scheduler analysis to low-level assembly context switching. By leveraging Openclaw Skills, developers can ensure that the complex ST codebase is managed with precision, maintaining the high performance and stability required for real-time media streaming.
This skill is essential for tasks that involve modifying the ST source, adding support for new CPU architectures, or debugging intricate memory and synchronization issues. It enforces a strict workflow that includes loading a comprehensive knowledge base and running mandatory verification scripts to prevent regressions in the core SRS threading model.
st-develop Use Cases
- Porting State Threads to new CPU architectures or operating systems using platform-specific assembly.
- Debugging coroutine context switching and internal scheduler behaviors (sched, stk, sync).
- Resolving complex memory issues detected by ASAN, Valgrind, or SEH.
- Updating the srs-coroutines.md knowledge base to reflect changes in the concurrency model.
- Developing and executing unit tests for TCP connections and coroutine lifecycle management.
How st-develop Works
- Dynamically resolves the SRS_ROOT directory by checking environment variables, workspace paths, or user input.
- Loads the mandatory srs-coroutines.md knowledge base to provide the AI agent with technical context.
- Retrieves the complete ST source tree, including core C files, headers, and platform assembly, to ensure no partial analysis occurs.
- Facilitates code modifications or debugging sessions within the 3rdparty/st-srs directory.
- Executes platform-specific build targets (e.g., linux-debug-utest) to compile the library and link unit tests.
- Runs the dedicated verification script to validate all changes against the existing SRS infrastructure via Openclaw Skills.
st-develop Setup
To use this skill, ensure your environment has access to the SRS repository. The skill dynamically resolves the project root, but you can explicitly set it for consistency.
# Optional: Define the SRS root path
export SRS_ROOT=~/git/srs
# Ensure the verification script is executable
chmod +x scripts/verify.sh
The skill requires the Google Test-based unit test suite located in trunk/3rdparty/st-srs/utest/ to be present for verification.
st-develop Data Schema & Taxonomy
The skill organizes its operations around the SRS source tree. Below is the metadata taxonomy and file organization:
| Component | Location | Description |
|---|---|---|
| Knowledge Base | memory/srs-coroutines.md |
Required technical documentation for ST internals. |
| Core Source | trunk/3rdparty/st-srs/*.c |
Implementation of sched, sync, io, and event logic. |
| Platform ASM | trunk/3rdparty/st-srs/md_*.S |
Assembly for Darwin, Linux, and Cygwin context switching. |
| Unit Tests | trunk/3rdparty/st-srs/utest/ |
GTest files for coroutine and network validation. |
| Build System | trunk/3rdparty/st-srs/Makefile |
Defines targets for debug, utest, and gcov builds. |
st-develop Advanced Features
- Multi-platform support for Darwin, Linux, and Cygwin64 build environments.
- Automated GCOV integration for measuring code coverage during coroutine testing.
- Dynamic path resolution to handle varying developer workspace configurations without hardcoding.
- Full-stack source loading requirement to prevent errors during complex refactoring.
- Integrated verification workflow through Openclaw Skills to maintain library integrity.
