adk-debug

A command for debugging an ADK application, meaning an application built with an agent development kit. It checks the setup, reproduces the problem, reads logs and traces, finds the cause, verifies the fix, and records a regression test.

In plain words
What is it for?
Use it to investigate broken, slow, or unusual agent behavior, inspect a specific tool or workflow, reproduce errors, and add an evaluation that checks the repaired behavior.
Why use it?
It provides a repeatable path from a vague failure or pasted error to a verified fix. It also helps prevent the same bug from returning.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 325 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

adk-debug scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Load the adk-debugger and adk skills, then start debugging immediately.

If $ARGUMENTS is vague ("broken", "not working", "slow", "weird", or empty), don't ask "what's wrong?" — investigate first. Run adk check --format json and adk logs error --format json, then present what you found.

If $ARGUMENTS mentions a specific component ("the search tool", "my workflow"), go directly to traces filtered by that component.

If $ARGUMENTS contains a pasted error or stack trace, read the file at the referenced line number immediately.

Debug Workflow

  1. Run adk check --format json to rule out offline issues first.
  2. Reproduce with adk chat --single "<relevant message>" --format json.
  3. Read traces and logs: adk logs error --format json, adk traces --format json.
  4. Identify root cause using the debug workflow from the skill.
  5. Suggest a targeted fix.
  6. Verify the fix with another adk chat or adk check.
  7. Write a regression eval for the bug — load the adk-evals skill, generate the eval file using the reproduction message as the user turn and the verified behavior as assertions, save it to evals/, and run adk evals <name> to confirm it passes.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

adk-debug is a command published in the GitHub repository botpress/skills (11 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 325 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
