What it does
Code Assist is an agent skill from qualcomm/qai-appbuilder. A professional programming assistant supporting code writing, debugging, review, refactoring, and performance optimization, as well as open-source repository analysis.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Refactoring, Performance optimization and Debugging. The repository describes itself as: QAI AppBuilder is designed to help developers easily execute models on WoS and Linux platforms. It encapsulates the Qualcomm® AI Runtime SDK APIs into a set of simplified…
When your agent uses it
- Tasks that involve Refactoring
- Tasks that involve Performance optimization
- Tasks that involve Debugging
Example prompts
- “/code-assist”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Understand requirements: first confirm the user's specific goals and constraints
- Read context: if the user provides file paths, first use the read tool to read the relevant files
- Analyze the problem: understand the existing code structure and where the problem lies
- Implement changes: use the edit tool for precise modifications, or the write tool to create new files
- Verify results: use the exec tool to run the code and confirm the changes are correct
- Report results: clearly describe what changes were made and why
What it can do on your machine
Read from SKILL.md and the folder at commit 700121f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Code Assist loads about 864 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 383 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 383 words (~864 tokens).
