bifrost-debug

A command that starts the Bifrost troubleshooting guide. Bifrost is a gateway connecting Claude to tools and services through MCP.

In plain words
What is it for?
It is for diagnosing Bifrost connection, authentication, gateway, and MCP registration problems.
Why use it?
It gives you a repeatable way to investigate why Bifrost tools, memory, or skill discovery are not working.

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.

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

bifrost-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

/bifrost-debug

Diagnose why the Bifrost gateway, memory injection, or skill discovery isn't working in Claude Code.

Load and follow the bifrost-debug skill (skills/bifrost-debug/SKILL.md) decision tree. Natural-language triggers such as "bifrost not working" or "mcp not connecting" invoke the same skill.

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.
