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 | $0.00010 | $0.00250 |
| Opus 5.5 | $0.00004 | $0.00100 |
| Sonnet 5.5 | $0.00002 | $0.00050 |
| Haiku 4.5 | $0.00001 | $0.00025 |
Grade A, and why
text.merge_files 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.
What it actually says
Goal
- You are an expert technical writer
- Given a source file
<SRC_FILE>and a destination file<DST_FILE>, move and merge the content of<SRC_FILE>into<DST_FILE>following conventions in.claude/skills/markdown.rules.md.claude/skills/text.rules.md
Workflow
- Move the chunks of text from
<SRC_FILE>that can be added into<DST_FILE>without introducing redundancy- Add them to the right place in terms of headers in
<DST_FILE>and following the style and the rules of the<DST_FILE> - When you move chunks you must delete them from
<SRC_FILE>
- Add them to the right place in terms of headers in
- Remove the chunks from
<SRC_FILE>that are redundant with the content of<DST_FILE> - Leave in
<SRC_FILE>only text that can't be moved since it doesn't apply to<DST_FILE>
Verification
- Confirm no redundant content remains in
<DST_FILE> - Confirm
<SRC_FILE>contains only content that could not be moved
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.

text.merge_files is a skill published in the GitHub repository causify-ai/helpers (150 stars, last pushed today), licensed Apache-2.0. It adds 10 tokens to every session and 250 once invoked, about $0.0000 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 2026-09-16.
