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 | $0.00463 | $0.00463 |
| Opus 5 | $0.00231 | $0.00231 |
| Sonnet 5 | $0.00093 | $0.00093 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
file-conversion CLAUDE.md scanned grade A 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 7d 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
Markdown → Word conversion shells out to `pandoc` (`subprocess.run(['pandoc', ...])`). Pandoc must be installed on the host (`brew install pandoc`). The code raises a clear error if pandoc is missing rather than installi How it starts

file-conversion — operating notes
Read this when working inside this project. See requirements/requirements.md for the CLI spec and requirements/mcp.md for the MCP server spec.
Two interfaces, one library
- Library (
file_conversion.coreandfile_conversion.gxp) — pure functions that take and return file paths. No I/O side effects other than reading inputs and writing outputs. Easy to test in isolation. - CLI (
.venv/bin/file-conversion) — Click wrapper around the library, for the user and for shell scripts. - MCP server (
python -m file_conversion.mcp_server) — same library exposed to Claude Desktop. Required because the bash sandbox can't import this project's venv.
All three wrap the same functions. Bug fixes apply once.
System dependency: pandoc
Markdown → Word conversion shells out to pandoc (subprocess.run(['pandoc', ...])). Pandoc must be installed on the host (brew install pandoc). The code raises a clear error if pandoc is missing rather than installing it silently.
GxP template
md_to_docx_gxp does three things beyond the plain converter:
- Inserts a version table at the top of the document, populated from YAML frontmatter (
versions:list) or empty if absent. - Inserts a definitions table after the version table, populated from frontmatter (
definitions:list) or empty if absent. - Sets a footer on every page showing
<title> — v<version>, sourced from frontmatter (title:,version:) and overridable via CLI flags.
The frontmatter schema lives in requirements/requirements.md. Keep the parser and the spec in sync — if the schema changes, update both.
Testing before suggesting a Claude Desktop restart
When MCP code changes, smoke-test via the CLI first since both wrap the same library. The CLI requires no restart; the MCP server does.
.venv/bin/pytest # unit tests
.venv/bin/file-conversion csv-to-xlsx a.csv b.xlsx # CLI smoke
Only suggest a Claude Desktop restart after the CLI confirms the change works.
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.

file-conversion CLAUDE.md is an instructions file published in the GitHub repository jmcneil86043/file-conversion (0 stars, last pushed 13d ago), licensed Apache-2.0. It adds 463 tokens to every session, about $0.0023 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
