What it does

Debug Agent is an agent skill from bitsocialnet/5chan. Investigate a reported bug using source, tests, or runtime evidence to establish its cause.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A peer-to-peer 4chan alternative. The licence is GPL-3.0.

Example prompts

  • “/debug-agent”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Establish the expected behavior, reproduction, affected environment, and success criteria. Inspect file history when the report identifies…
  2. Trace the real execution path. Use existing tests, stack traces, logs, and runtime evidence before creating more instrumentation.
  3. State the plausible causes and choose the cheapest check that distinguishes them. A failing regression test or deterministic source-level…
  4. Reproduce autonomously using available tools when possible. Ask for a user-only reproduction step only when access or missing information…
  5. Apply the smallest fix supported by the evidence, preserving unrelated changes.
  6. Verify the original failure and relevant edge cases. Follow the repository's verification requirements once for the final state.
  7. Remove temporary instrumentation and files owned by this task after verification, and report the cause, fix, and evidence. Do not require…

What it can do on your machine

Read from SKILL.md and the folder at commit a31f565. 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

Debug Agent loads about 663 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 360 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~663

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.

Debug a Bug

  1. Establish the expected behavior, reproduction, affected environment, and success criteria. Inspect file history when the report identifies a file or line.
  2. Trace the real execution path. Use existing tests, stack traces, logs, and runtime evidence before creating more instrumentation.
  3. State the plausible causes and choose the cheapest check that distinguishes them. A failing regression test or deterministic source-level error can be sufficient; not every bug needs a logging server.
  4. Reproduce autonomously using available tools when possible. Ask for a user-only reproduction step only when access or missing information prevents progress; reuse the agreed method in later iterations.
  5. Apply the smallest fix supported by the evidence, preserving unrelated changes.
  6. Verify the original failure and relevant edge cases. Follow the repository's verification requirements once for the final state.
  7. Remove temporary instrumentation and files owned by this task after verification, and report the cause, fix, and evidence. Do not require another confirmation when the authorized automated check proves success.

When instrumentation is needed

  • Add a small number of logs tied to specific hypotheses; avoid credentials, personal data, and arbitrary content dumps.
  • Prefer the application's existing logger or test harness. Use an existing local debug service if useful; do not install or require a new daemon by default.
  • Use a task-specific log file and mark temporary code clearly. Never clear another session's logs.
  • Collect before/after evidence. If a hypothesis fails, remove its speculative fix and revise the investigation.
  • If user-only verification remains pending, state the limitation and retain only the instrumentation needed for that verification, unless the user requests cleanup.

Optional file discovery

If ordinary search leaves a large but explicit source shortlist, Jev file questions can help prioritize direct inspection. Supply task-specific bounded questions and only task-authorized files; live calls require explicit --live and a budget. Keep negative and uncertain results visible, inspect their source/dependencies when needed, and read source before editing. This is optional evidence selection, not a command runner or proof of a diagnosis. The initial pilot did not establish workflow savings; do not run it routinely or treat low API cost as justification. Prefer direct reading when it is cheaper.

Can I use Debug Agent 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 bitsocialnet/5chan --skill debug-agent -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/debug-agent, .gemini/skills/debug-agent, .github/skills/debug-agent and .opencode/skills/debug-agent in your project.

What does Debug Agent need to run?

SKILL.md names no scripts, command-line tools or credentials: Debug Agent is instructions for the agent only.

Does Debug Agent access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Debug Agent 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 Debug Agent use?

Debug Agent is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Debug Agent use?

About 663 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
