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 | $0.00048 | $0.01078 |
| Opus 5.5 | $0.00019 | $0.00431 |
| Sonnet 5.5 | $0.00010 | $0.00216 |
| Haiku 4.5 | $0.00005 | $0.00108 |
Grade A, and why
simplify 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/simplify — Code Simplification
When the user invokes /simplify [scope], review code for safe simplifications and apply them with user approval.
| Command | Scope | What gets reviewed |
|---|---|---|
/simplify |
uncommitted | Staged + unstaged changes (default) |
/simplify HEAD~N |
recent commits | Changes in the last N commits |
/simplify <file> |
single file | Only that file |
Workflow
1. Determine Scope
Default to uncommitted changes when no argument is provided.
git status --short --branch
For uncommitted changes:
git diff --staged --name-only
git diff --name-only
For commit range (e.g., HEAD~3):
git diff HEAD~3 --name-only
For a single file, verify it exists and read it.
Stop if:
- no changed files in the requested scope
- merge conflicts are present
2. Read And Analyze
Read the full content of each changed file (not just the diff) so that simplifications are informed by surrounding context.
Look for:
| Category | Examples |
|---|---|
| Dead code | Unused imports, unreachable branches, commented-out blocks, unused variables/functions |
| Redundant logic | Duplicate conditions, double negation, unnecessary else after return, if x return true else return false |
| Naming | Misleading names, single-letter variables in non-trivial scope, inconsistent conventions within the file |
| Type tightening | Overly broad types (any, interface{}), missing return types, unnecessary type assertions |
| Unnecessary wrappers | Trivial wrapper functions, redundant intermediate variables, over-abstracted single-use helpers |
| Simplifiable expressions | Ternaries that can be boolean expressions, verbose null checks replaceable by optional chaining, long-form iterations replaceable by standard library calls |
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.

simplify is a command published in the GitHub repository n9e/fe (308 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 1,078 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-01.
