sirdas CLI

Same engine as the web app and the MCP server, from the terminal. No network, no accounts, no telemetry.

#Install

npx sirdas factura.pdf       # nothing to install but Node 20+
npm i -g sirdas              # or keep it around

md is an alias of markdown.

#Conventions agents can rely on

• Exit codes: 0 success · 1 usage error (bad flags, missing input, refusing to overwrite) · 2 the file could not be processed (password-protected, damaged, not a PDF). The reason is printed to stderr in one sentence.
• stdout is the payload. markdown prints Markdown; with --json it prints one JSON object (markdown, pages, tokens_estimate, anonymized, redacted, has_text, source). Progress and warnings go to stderr.
• Anonymization is on by default for markdown; --no-anonymize keeps the original data.
• Never overwrites an existing file without --force.
• anonymize --json includes the placeholder→value mapping; keep it local.

#The anonymize → AI → restore round trip

Nothing is ever deleted. The original PDF is untouched and the mapping — which holds the real values — stays on your machine.

# 1. Anonymize, keeping the mapping
sirdas markdown historia.pdf --json | jq -r .markdown > anonima.md
sirdas anonymize anonima.md --map mapa.json > anonima-final.md

# 2. Send anonima-final.md to any model, then restore its answer locally
cat respuesta-de-la-ia.txt | sirdas restore --map mapa.json

A name always comes back whole: placeholders map to the complete original value, never a fragment.

#Examples

# Markdown for an LLM, personal data replaced
sirdas markdown historia.pdf > historia.md

# Structured output for a script
sirdas markdown contrato.pdf --json | jq '.tokens_estimate, .redacted'

# Anonymize a snippet before pasting it anywhere
echo "Paciente: Ana Gómez, C.C. 52.123.456" | sirdas anonymize

# Split the first three pages and the last one
sirdas split informe.pdf --ranges "1-3, 8-end" -d ./partes

# Pull an invoice's line items into a spreadsheet (CSV carries a BOM for Excel)
sirdas tables factura.pdf --delimiter ";" -d ./tablas

# Split a long document into chat-sized pieces
sirdas chunks informe.pdf --max-tokens 2000 -d ./partes

# Merge, then shrink losslessly
sirdas merge a.pdf b.pdf -o todo.pdf && sirdas compress todo.pdf
