Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00106 | $0.01013 |
| Opus 5.5 | $0.00042 | $0.00405 |
| Sonnet 5.5 | $0.00021 | $0.00203 |
| Haiku 4.5 | $0.00011 | $0.00101 |
Grade A, and why
archlang-export 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Export a plan
Produce drawing files from a .arch plan.
If archlang is not on the path, write npx -y @chanmeng666/archlang in its place.
Never run a bare arch: on Linux, macOS and Git Bash that name is the coreutils command.
This skill is a workflow, not a language reference. archlang compile --help lists every format and
flag; archlang spec describes the paper and scale statements.
Steps
- Check the plan compiles.
archlang compile plan.arch --jsonwrites nothing and reportsokand the diagnostics. Do not export a plan with errors; fix it first. - Make sure it is a sheet. A plan with no
paperstatement has no physical size.archlang finish plan.arch --only sheet --dry-run --jsonshows the sheet statements the plan lacks (paper, scale, dimensions, title block, room schedule, legend).archlang finish plan.arch --only sheetadds them on the smallest sheet the drawing fits. - If the user names a paper size or a scale, edit the plan's
paperandscalestatements to those values and compile again. If the drawing does not fit the sheet the plan declares,archlang finish plan.arch --reissue -o issued.archwrites a copy in which onlypaperandscaleare replaced by ones that fit. Tell the user when the sheet they asked for cannot hold the drawing at that scale. - Export. Pick the format by what the file is for:
- SVG, for the web or further editing:
archlang compile plan.arch -o plan.svg --json - PDF, for print at true size:
archlang compile plan.arch -f pdf -o plan.pdf --install --json - PNG, for a document or a chat:
archlang compile plan.arch -f png -o plan.png --install --json(-s 2doubles the raster scale) - DXF, for CAD:
archlang compile plan.arch -f dxf -o plan.dxf --json
- SVG, for the web or further editing:
- Multi-storey plans. A plan written with
levelblocks compiles to one file per storey, named<stem>.L<level>.<ext>, and the JSON result lists them inoutputs[]. To write one storey to one named file, add--level <n>. - Many plans at once. Create the output directory first;
batchdoes not create it. Thenarchlang batch a.arch b.arch -f pdf -o out/ --jsonrenders each input into it and returns one result row per input. - Confirm what was written. Read
output(oroutputs[]for a multi-storey plan) andbytesin the JSON result and list the files for the user. For a PNG you can look at it; for the other formats report the path, the sheet size and the scale.
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.

archlang-export is a skill published in the GitHub repository ChanMeng666/archlang (18 stars, last pushed today), licensed MIT. It adds 106 tokens to every session and 1,013 once invoked, about $0.0004 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 2026-10-10.

document-processing
Use when the deliverable is a document's bytes or its literal content — text/tables out of PDFs, AcroForm fill and flatten, page merge/split, PDF/DOCX from templates, OCR of image-only scans. NOT schema-typed fields pulled from text (that is structured-extraction), NOT signature routing (e-signature) or spreadsheet…
ocr-and-documents
Extract text from PDFs and scanned documents. Use webextract for remote URLs, pymupdf for local text-based PDFs, marker-pdf for OCR/scanned docs. For DOCX use python-docx, for PPTX see the powerpoint skill.
nano-pdf
Edit PDFs with natural-language instructions using the nano-pdf CLI. Modify text, fix typos, update titles, and make content changes to specific pages without manual editing.
foundry-hosted-agent-validation
Step-by-step process for validating a Python Foundry hosted agent sample (under python/samples/04-hosting/foundry-hosted-agents/) end to end — running it locally (native runtime and azd ai agent run) and after deploying it to an Azure AI Foundry project with azd. Use this when asked to validate a hosted agent sample.
report-to-pdf
Narrow conversion skill. Invoke only when the user explicitly asks to convert an existing Data Analytics report, dashboard, or inline chart export into a PDF artifact.
pdf-official
Use this skill whenever a PDF file is being produced, opened, transformed, filled, or read. That includes: extracting text or tables from an existing PDF; combining, carving, rotating, cropping, or watermarking pages; composing a fresh PDF (report, invoice, certificate); filling AcroForm fields or overlaying text onto…
