debug-infra

A guided process for investigating infrastructure problems across networking, permissions, service health, and logs. Infrastructure means the cloud services and network resources that applications run on.

In plain words
What is it for?
Use it to investigate failed deployments, timeouts, connection errors, 5xx responses, permission failures, missing resources, and unexpected service behavior.
Why use it?
It gives developers an ordered set of checks instead of requiring them to guess whether the problem is connectivity, permissions, deployment, or service health.

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.

Made for: Claude Code.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 443 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

debug-infra 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 yesterday.

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

Debug Infrastructure

Systematically diagnose infrastructure issues.

Steps

  1. Gather symptoms. Ask the user what they are experiencing:

    • Can't connect to a service
    • Deployment failed
    • Timeouts or high latency
    • 5xx errors
    • Permission denied
    • Resource not found
    • Unexpected behavior
  2. Identify the affected resource. Call terror_status to list resources and ask the user to confirm which resource or service is affected.

  3. Systematic checks. Based on the symptom, run through the relevant checks in order:

    Connectivity issues (can't connect, timeout):

    • Check resource health via terror_health
    • Verify the resource is running and in the correct state
    • Check security groups / firewall rules for the relevant ports
    • Verify DNS resolution if a domain is involved
    • Check VPC routing and subnet configuration
    • Test from the same network context (public vs private)

    Permission errors (403, permission denied):

    • List IAM bindings on the resource (gcp_iam_list, aws_iam_list)
    • Check the service account or role being used
    • Verify the required permissions for the operation
    • Check for org-level policies or SCPs that might block access

    5xx errors:

    • Check service health and recent deployments
    • Look at resource utilization (CPU, memory, connections)
    • Check dependent services (database, cache, external APIs)
    • Review recent configuration changes

    Deployment failures:

    • Check the deployment logs
    • Verify the container image or artifact exists
    • Check resource quotas and limits
    • Verify IAM permissions for the deployment service account
  4. Hypothesis and resolution. After gathering data:

    • State the most likely root cause
    • Propose a fix with the specific Terror commands to run
    • Use the decision gate before applying any changes
    • Verify the fix resolves the issue

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.
