learn-pattern

A command for saving a recurring error pattern, its meaning, and its fix in memory for later recognition. For example, it can record that Kubernetes' ImagePullBackOff means a container image could not be downloaded.

In plain words
What is it for?
Recording errors such as ImagePullBackOff, explaining what they mean, and noting practical checks or fixes such as inspecting the image name, tag, registry credentials, pod details, and events.
Why use it?
It prevents useful troubleshooting knowledge from being lost and makes familiar errors easier to recognize and resolve in future work.

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

learn-pattern 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.

Overview

Save a new error pattern to memory for future recognition.

Underlying Skill: learn_pattern

This command is a wrapper that calls the learn_pattern skill. For detailed process information, see skills/learn_pattern.md.

fix No -

Usage

Examples

skill_run("learn_pattern", '{"pattern": "OOMKilled", "meaning": "Container exceeded memory limit", "fix": "Increase memory limits"}')
/learn-pattern

## Details

## Usage

When you discover an error pattern and its fix, teach the AI to remember it:

```text
skill_run("learn_pattern", '{"pattern": "OOMKilled", "meaning": "Container exceeded memory limit", "fix": "Increase memory limits"}')
```text

## Categories

- **pod_errors**: Kubernetes pod issues (CrashLoopBackOff, ImagePullBackOff, etc.)
- **log_patterns**: Error messages found in logs
- **network**: Network-related issues
- **general**: Default category

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.
