The `my` skill lets agents diagnose and adjust runtime configuration by checking or setting the model, iteration limits, context window size, token usage, and web access settings. Use it when troubleshooting failures (why web search isn't working), assessing resource availability before complex tasks, optimizing for specific workloads (fast models for repetitive tasks, larger context windows for code analysis), or answering user questions about current model and resource status. Changes persist only within the current session.

# Self-Awareness

## How to use

1. **Identify the situation** from the categories below
2. **Call the my tool** with the appropriate action
3. **If set**, warn the user before changing impactful settings such as the model or runtime limits
4. **For detailed examples**, read [references/examples.md](references/examples.md)

## When to check

<rule>
**Diagnose before explaining.** When something doesn't work, check your state first.
</rule>

<rule>
**Check budget before complex tasks.** Know your limits before committing.
</rule>

<rule>
**Recall across turns.** Store preferences in your scratchpad, read them back later.
</rule>

## When to set

<rule>
**Only set when benefit is clear and user is informed.** Warn before changing model.
</rule>

| Situation | Command |
|-----------|---------|
| Check capacity for a large task | `my(action="check", key="context_window_tokens")` |
| Switch model or context capacity | `my(action="set", key="model_preset", value="<preset-name>")` |
| Long multi-step task | `my(action="set", key="max_iterations", value=80)` |

**Tradeoff:** Bias toward stability. Only set when defaults are genuinely insufficient.

## Anti-patterns

<rule>
**Don't check every turn.** Costs a tool call. Use when you need information, not reflexively.
</rule>

<rule>
**Don't store sensitive data.** No API keys, passwords, or tokens in scratchpad.
</rule>

<rule>
**Don't set workspace.** Does not update file tool boundaries — won't work.
</rule>

## Constraints

- `model_preset` is saved for the current session; other modifications are in-memory only
- Direct `model` and `context_window_tokens` writes are rejected during active sessions because they would change the shared instance default. Use a configured `model_preset` instead.
- Protected params have type/range validation: `max_iterations` (1–100), `context_window_tokens` (4096–1M), `model` (non-empty str)
- If `tools.my.allow_set` is false, check only

| Need | Use | Persists? |
|------|-----|-----------|
| Per-session temp state | `my(action="set", key="...", value=...)` | No |
| Long-term facts | Memory skill (`MEMORY.md`, `USER.md`) | Yes |
| Permanent config change | Edit config file | Yes |

**Rule of thumb:** Tomorrow? Memory. This turn only? My.
