What it does
Debugging is an agent skill from dxos/dxos. Use when instrumenting code with runtime logs to test a hypothesis — @dxos/log debug lines captured to app.log (browser), test.log (node tests), or test-browser.log (browser tests/storybook), and querying them with query-logs.mjs. Reference for the log-exfiltration pipeline and instrumentation mechanics, not a debugging workflow.
Its SKILL.md is about 1.8k 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 Debugging. It works with Storybook and Vitest. The repository describes itself as: TypeScript implementation of the DXOS protocols, SDK, toolchain and Composer.
When your agent uses it
- Instrumenting code with runtime logs to test a hypothesis — @dxos/log debug lines captured to app.log (browser)
- Test.log (node tests)
- Test-browser.log (browser tests/storybook)
- Querying them with query-logs.mjs
Example prompts
- “/debugging”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Rotate the sink before each reproduction — app.log only self-truncates on dev-server restart, so clear it between iterations, but move the…
- Reproduce (yourself via browser tools whenever possible — see debugging-ui).
- Check size first (wc -l), then extract only your lines
What it can do on your machine
Read from SKILL.md and the folder at commit f0fc12a. 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
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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
Debugging loads about 1.8k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 807 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 807 words (~1,818 tokens).
“Mechanics for hypothesis-testing with runtime logs. The debugging process — hypotheses, isolation, verification, user interaction — is owned by the calling skill (debugging-ui for UI bugs) or workflow; this skill is only how to get signals out of running code…”

When should I use Debugging?
Debugging fits situations like: instrumenting code with runtime logs to test a hypothesis — @dxos/log debug lines captured to app.log (browser); test.log (node tests); test-browser.log (browser tests/storybook); querying them with query-logs.mjs.
How do I install Debugging in Claude Code?
Run `npx skills add dxos/dxos --skill debugging -a claude-code`. Or copy the skill folder (.agents/skills/debugging in dxos/dxos) into .claude/skills/debugging in your project. Claude Code loads it when a task matches its description.
How do I install Debugging in Codex?
Run `npx skills add dxos/dxos --skill debugging -a codex`. Or copy the skill folder (.agents/skills/debugging in dxos/dxos) into .agents/skills/debugging in your project. Codex loads it when a task matches its description.
Can I use Debugging in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add dxos/dxos --skill debugging -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/debugging, .gemini/skills/debugging, .github/skills/debugging and .opencode/skills/debugging in your project.
What does Debugging need to run?
Going by SKILL.md and its folder, Debugging needs the command-line tools its instructions call (node).
Does Debugging access the network?
SKILL.md names 1 domain. As links in the text: github.com. This is read from the text; nothing was executed.
Is Debugging safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Debugging use?
Debugging has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Debugging use?
About 1.8k tokens (SKILL.md is roughly 7.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
