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 | $0.06009 | $0.06009 |
| Opus 5 | $0.03004 | $0.03004 |
| Sonnet 5 | $0.01202 | $0.01202 |
| Haiku 4.5 | $0.00601 | $0.00601 |
Grade B, and why
hs-to-rocq CLAUDE.md scanned grade B 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 11d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
**Container job gotcha**: Container jobs use `--allow-different-user` for stack commands (ownership mismatch between host-mounted workspace and container user). For docker-coq-action, use `before_script` with `sudo chown How it starts

Project Overview
hs-to-rocq converts Haskell source code to Coq (Gallina) using the GHC API. It is part of the DeepSpec/CoreSpec project. The tool parses Haskell via GHC, applies user-specified "edits" to guide the translation, and pretty-prints valid Coq output.
- Current target: GHC 9.10.3, Coq 8.20 (branch
ghc910-coq820) - Languages: Haskell (the tool, ~14K LOC in
src/), Coq (generated output and proofs)
Build Commands
stack build # Build hs-to-rocq executable
stack exec hs-to-rocq -- -e edits -o output/ Input.hs # Run on a file
make # Build base + base-thy + containers
make -C examples/base-src vfiles # Re-generate base/ from Haskell sources
make -C examples/tests # Unit tests (.hs → .v → coqc)
make -C examples/base-tests # Tests requiring base/
make -C examples/containers # containers lib + theories (regenerates + builds)
make -C examples/transformers # transformers lib
make -C examples/ghc clean && make -C examples/ghc # Regenerate+compile GHC lib + theories
cd examples && ./boot.sh # Full bootstrap (all examples)
# Individual Coq dirs: cd <dir> && coq_makefile -f _CoqProject -o Makefile && make -j
Use relative path instead of absolute path when cd to a directory.
CI commands
/ci— run CI checks locally, report pass/fail/ci-fix— run CI checks, diagnose and fix failures, commit fixes
Architecture
Translation Pipeline
- Parse & typecheck Haskell via GHC API (
src/lib/HsToRocq/ProcessFiles.hs) - Load edits from
.editsfiles (src/lib/HsToRocq/Edits/Parser.y,Types.hs) - Convert GHC AST → Coq Gallina AST (
src/lib/HsToRocq/ConvertHaskell/) - Pretty-print Gallina to
.vfiles (src/lib/HsToRocq/Rocq/Pretty.hs) - Output
.h2ciinterface files for cross-module translation
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.

hs-to-rocq CLAUDE.md is an instructions file published in the GitHub repository plclub/hs-to-rocq (96 stars, last pushed 2mo ago), licensed MIT. It adds 6,009 tokens to every session, about $0.0300 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
