diagnose

diagnose is a command for coding agents from kouroshez/coding-os. It costs 0 tokens per session (103 once invoked), scanned A, original, Apache-2.0.

A command for running health checks on the coding system and explaining the results.

In plain words
What is it for?
Use it to inspect overall system health, understand failed or warned checks, and get the exact commands needed for repairs.
Why use it?
It helps find configuration, database, adapter, or link problems and separates warnings from failures that need fixing.

Getting it into your agent

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

diagnose 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 3d 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

Run system health diagnostics and interpret the results.

Steps:

  1. Run cos doctor — deep health check (scaffold, DB schema, adapter, symlinks). Use cos health for a fast summary if doctor is too slow.
  2. For each FAIL item: explain what's wrong and give the exact fix command
  3. For each WARN item: explain if it matters for the current environment
  4. Summarize: what's healthy, what needs attention, and prioritized fix order
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.

diagnose is a command published in the GitHub repository kouroshez/coding-os (6 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 103 tokens. 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 2026-08-31.
