What it does
Agent Communication Debugger is an agent skill from aiskillstore/marketplace. Diagnoses and debugs A2A agent communication issues including agent status, message routing, transport connectivity, and log analysis. Use when agents aren't responding, messages aren't being delivered, routing is incorrect, or when debugging orchestrator, coder-agent, tester-agent communication problems.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `README.md`, `common_issues.md` and `scripts/test_message.py`).
It sits in Development. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Agents arent responding
- Messages arent being delivered
- Routing is incorrect
- Debugging orchestrator
Example prompts
- “t responding, messages aren”
- “Use the agent-communication-debugger skill to diagnose and debugs A2A agent communication issues including agent status, message routing, transport…”
- “/agent-communication-debugger”
Requirements
- Python 3
- A credential in OPENAI_API_KEY
- A credential in API_KEY
- Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob
Workflow steps
9 steps, taken from the step headings in SKILL.md.
- Check Agent Status
- Inspect Agent Configurations
- Check Agent Logs
- Verify Message Transport
- Test Message Sending
- Diagnose Routing Issues
- Check Environment Variables
- Restart Agents (if needed)
- Common Issues and Solutions
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
OPENAI_API_KEYAPI_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Communication Debugger loads about 2.8k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 747 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:157
grep -E "(model|MODEL)" .env 2>/dev/null | sed 's/=.*/=***HIDDEN***/' || echo "No .env file" - NoteMentions a .env fileSKILL.md:299
# Or add to .env file - NoteMentions a .env fileSKILL.md:300
echo "OPENAI_API_KEY=your-key-here" >> .env - NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Grep, Glob
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 747 words (~2,805 tokens).
“Debug and diagnose issues with the A2A (Agent-to-Agent) communication system, including the orchestrator, coder-agent, tester-agent, and message transport layers.”
