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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01984 |
| Opus 5 | $0.00024 | $0.00992 |
| Sonnet 5 | $0.00010 | $0.00397 |
| Haiku 4.5 | $0.00005 | $0.00198 |
Grade A, and why
refactor-simplifying-method-calls 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 9d 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.

Refactor: Simplifying Method Calls
Overview
These 14 techniques improve method interfaces -- making them easier to understand, call correctly, and maintain. Clean method signatures are your code's API contract; unclear signatures lead to misuse and tight coupling.
When to Use
- Method name doesn't describe what it does
- 4+ parameters
- Boolean flag parameters switch behavior
- Caller extracts data just to pass as parameters
- Method does both query and command (side effects + return value)
Quick Reference
| Technique | Problem | Solution |
|---|---|---|
| Rename Method | Name doesn't communicate intent | Descriptive name |
| Add Parameter | Method needs additional data | Add parameter (consider alternatives first) |
| Remove Parameter | Parameter unused | Delete it |
| Separate Query from Modifier | Returns value AND changes state | Split into query + command |
| Parameterize Method | Multiple methods do same thing with different values | One method with a parameter |
| Replace Parameter with Explicit Methods | Parameter switches between different behaviors | Separate method per value |
| Preserve Whole Object | Extracting values from object to pass as params | Pass the whole object |
| Replace Parameter with Method Call | Callee can obtain the value itself | Callee gets value directly |
| Introduce Parameter Object | Same group of params appears together | Bundle into an object |
| Remove Setting Method | Field should not change after creation | Remove setter, set in constructor |
| Hide Method | Method not used outside its class | Make private |
| Replace Constructor with Factory Method | Constructor too limited | Factory method |
| Replace Error Code with Exception | Special return values indicate errors | Throw exceptions |
| Replace Exception with Test | Exception used for control flow | Check condition before calling |
Techniques in Detail
1. Rename Method
The simplest and most valuable refactoring.
// Before
function dt(d1: Date, d2: Date): number { /* ... */ }
// After
function daysBetween(start: Date, end: Date): number { /* ... */ }
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.

refactor-simplifying-method-calls is a skill published in the GitHub repository mickeyyaya/refactoring-skills (6 stars, last pushed 5mo ago), licensed MIT. It adds 49 tokens to every session and 1,984 once invoked, about $0.0002 per session on Opus 5. 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.
