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 | $0.02445 | $0.02445 |
| Opus 5.5 | $0.00978 | $0.00978 |
| Sonnet 5.5 | $0.00489 | $0.00489 |
| Haiku 4.5 | $0.00245 | $0.00245 |
Grade A, and why
mcp-htmleditor AGENTS.md 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md, mcp-htmleditor
Overview
WYSIWYG HTML editor plus MCP server, with PPTX and DOCX export. LLM agents modify HTML files on disk; the browser renders them in an iframe and reloads on mtime change. Python 3.13+, uv, click, FastMCP, python-pptx, BeautifulSoup4, pandoc for DOCX.
Key commands
make is the only entry point. Never call uv, ruff, mypy or pytest directly.
make sync # uv sync (deps + dev group)
make check # GATE: check-generated + lint + format-check + typecheck + security + test-cov (80 %)
make test # pytest -v (ARGS='-k pptx' for a subset)
make test ARGS='-m slow' # real 30 s and 5 min HTTP bounds, literal 60 s / 900 s test limits, 30 s stdio bound (minutes, not run by make check)
make install # uv tool install (with the render extra) + templates + log dir + Pi skill
make install-browser # Chromium for `render` (needs the render extra)
make run ARGS='export pptx in.html out.pptx'
make docker-build / run-up / run-down
make bootstrap-ei # regenerate the EI bootstrap from the EI reference
make sync-medical-css # propagate the medical charter CSS to the reference decks
make check-generated # verify both generated template families are fresh (writes nothing)
make help # every target
CLI (same after make install):
mcp-htmleditor --version
mcp-htmleditor templates # ei, carbon, medical, doc, doc-perso, doc-ei, mail, website
mcp-htmleditor new ei pres.html --serve
mcp-htmleditor new medical talk.html --serve
mcp-htmleditor serve file.html [-v|-q] [--host] [--port] [--poll] [--no-browser]
mcp-htmleditor mcp # MCP server (stdio)
mcp-htmleditor export pptx in.html out.pptx
mcp-htmleditor export docx in.html out.docx
mcp-htmleditor arch-layout in.html # compute arch-diagram positions from topology
mcp-htmleditor arch-checklist # print the editable arch-diagram QA checklist
mcp-htmleditor skill # skill core (rules, tools, topic index)
mcp-htmleditor skill --type <topic> # one of the 15 topics
mcp-htmleditor skill --all # core then every topic
mcp-htmleditor requests file.html # requests queued from the editor, oldest first
mcp-htmleditor request-done file.html R-0001
mcp-htmleditor request-skip file.html R-0002 --reason "why"
mcp-htmleditor review file.html [--write list.json] # AI suggestions; --write replaces them
mcp-htmleditor skill-audit [--json] # sizes, tool list, stale statements; exit 1 on a problem
mcp-htmleditor render file.html [--slide ID] [--scale 0.5] [--report] [--json] # PNG of a slide in <tmp>/htmleditor-render
mcp-htmleditor render file.html --report-only [--json] # layout problems of every slide, no picture; exit 1 on a problem
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.
