plano-observability-debugging

plano-observability-debugging is a skill for Claude Code, Codex from katanemo/plano. It costs 32 tokens per session (212 once invoked), scanned A, original, Apache-2.0.

A set of instructions for using Plano, an observability tool that records request paths and timings, to investigate routing and performance.

In plain words
What is it for?
Use it to configure trace sampling, add useful details to spans, query traces, and produce commands for reproducing and checking findings.
Why use it?
It helps replace guesses about why a request was routed incorrectly or became slow with evidence from recorded traces.

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

plano-observability-debugging 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 4d 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

Plano Observability and Debugging

Use this skill to make routing and latency behavior inspectable and debuggable.

When To Use

  • "Enable tracing correctly"
  • "Add useful span attributes"
  • "Debug why a request routed incorrectly"
  • "Inspect filter/model latency from traces"

Apply These Rules

  • observe-tracing
  • observe-span-attributes
  • observe-trace-query

Execution Checklist

  1. Enable tracing with environment-appropriate sampling.
  2. Add useful static and header-derived span attributes.
  3. Use planoai trace filters to isolate route and latency issues.
  4. Prefer trace evidence over assumptions in recommendations.
  5. Return exact commands to reproduce and validate findings.
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.
