What is corpus-reconvert?

A measurement workflow for checking how a converter change affects a test corpus. A corpus is a collection of representative inputs; the workflow compares outputs, checks markers, rebuilds results, and groups the differences.

Use it to measure a converter's changed outputs across targets, inspect differences, and repeat the conversion and build checks.

It shows whether a conversion change altered more inputs than expected and helps separate real output changes from build or comparison noise.

Token cost

What it costs to keep this loaded

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	$0.00041	$0.14982
Opus 5	$0.00020	$0.07491
Sonnet 5	$0.00008	$0.02996
Haiku 4.5	$0.00004	$0.01498

Security

Grade C, and why

corpus-reconvert scanned grade C with 1 finding 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 today.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.

corpus-reconvert is a skill published in the GitHub repository ritchiecarroll/go2cs (399 stars, last pushed today), with no licence file. It adds 41 tokens to every session and 14,982 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-13.
