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 | $0.00048 | $0.00241 |
| Opus 5 | $0.00024 | $0.00120 |
| Sonnet 5 | $0.00010 | $0.00048 |
| Haiku 4.5 | $0.00005 | $0.00024 |
Grade A, and why
rename-symbol-literally 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 8d 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
Rename Symbol Literally
Replace an exact token with another exact token. This is text editing, not semantic refactoring.
Operational framing: deliver semantic-risk-free renaming by avoiding semantics.
Required Inputs
- Search scope: current file, listed files, or repository.
- Exact old token.
- Exact new token.
- Confirmation after showing match count.
Rules
- Match exact text only.
- Do not rename based on meaning.
- Do not alter case variants unless explicitly requested.
- Show match locations before applying repository-wide changes.
- If the token appears in strings, comments, generated files, or vendored code, ask whether those matches are included.
Output
Before changing:
Found <n> exact match(es) for <old-token>.
After changing:
Replaced <n> exact occurrence(s) of <old-token> with <new-token>.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rename-symbol-literally is a skill published in the GitHub repository valsteen/write-code-by-hand (5 stars, last pushed 2mo ago), licensed MIT. It adds 48 tokens to every session and 241 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.
