Add international text

add_international_text
Idempotent

Render PDF paragraphs in 27 international scripts, including Arabic, Hebrew, CJK, Devanagari, Thai and emoji, with BiDi, shaping and embedded fonts handled automatically.

Instructions

PDF rendering text in 27 scripts (Arabic, Hebrew, Thai, Lao, CJK, Devanagari, Bengali, Tamil, Telugu, Sinhala, Tibetan, Khmer, Myanmar, Tai Tham, New Tai Lue, Tai Le, Cham, Ethiopic, Cyrillic, Greek, Georgian, Armenian, Vietnamese, …; ha / yo / ig / sw are aliases of latin with anchored combining marks), COLRv1 colour emoji and mathematical symbols ('math': ∀ ∃ √ ∑ ∫ ∞). BiDi (UAX #9), Arabic joining and complex-script shaping are automatic; input is NFC-normalised; newlines split paragraphs. lang is a code or an array for mixed runs (['ar','emoji'], ['latin','math']). Fonts are always embedded, so embedFonts does not exist here. PDF/A, print, metadata and creationDate options as on every document tool.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
langYesLanguage / script identifier. Either a single code (e.g. 'ar'), a comma-separated list ('ar,emoji'), or an array (['ar','emoji']). Multiple codes enable multi-font run splitting (script + emoji + Latin fallback). 27 scripts; ha / yo / ig / sw (Hausa, Yoruba, Igbo, Swahili) are aliases of latin, whose combining marks are anchored.
pdfANoPDF/A level (Tagged PDF + sRGB OutputIntent + XMP). Fonts are embedded here, so the claim is valid as-is. See docs/guides/PDFA.md.
pdfxNoPDF/X-4 print exchange (ISO 15930-7). REQUIRES outputIntent with the printer's ICC profile (device class 'prtr'; CMYK or Gray — none is bundled); needs embedFonts:true for a conformant file (PDFX_NO_FONT_ENTRIES otherwise, strict:true refuses). Exclusive with pdfA and encrypt; metadata.trapped must be 'True' or 'False'; TrimBox or ArtBox, not both. Links and form fields are reported (PDFX_ANNOTATIONS). Check with validate_pdf standard:'pdf-x-4'. See the print_ready prompt.
debugNoDraw margin / block / cell guide rectangles (unmarked content — not for PDF/UA output). Geometry unchanged. Default false.
printNoPrint production (ISO 32000-1 §14.11): page boxes, `bleed` shorthand (TrimBox = MediaBox inset), crop/registration marks outside the TrimBox, /UserUnit for large formats (PDF 1.7; not under pdfa1b). See docs/guides/PRINT.md.
titleYesPDF title (rendered as page heading and stored as document metadata).
strictNoFail instead of producing a file the engine warns about: a PDFA_* diagnostic → PDF_A_COMPLIANCE_VIOLATION (e.g. PDFA_NO_FONT_ENTRIES without embedFonts), a PDFX_* one → PDF_X_COMPLIANCE_VIOLATION, any other → DIAGNOSTIC_ESCALATED. Pair with embedFonts=true.
encryptNoEncrypt at build time (AES-128 default / AES-256) and KEEP the AcroForm — unlike encrypt_pdf, which rebuilds the page tree. Exclusive with pdfA. Randomised output, never cached.
marginsNoMargins in points, all four required (0–200). Default 45 / 36 / 35 / 36.
compressNoFlateDecode the streams (smaller file, different bytes; PDF/A unaffected, XMP stays plain). Default false.
metadataNo/Info (+ XMP under PDF/A): author, subject, keywords, /Trapped.
pageSizeNoPortrait page preset (points): A4 595.28×841.89 (default), Letter 612×792, Legal 612×1008, A3 841.89×1190.55, Tabloid 792×1224. print.* boxes must fit it.
normalizeNoUnicode normalization before shaping. Default 'NFC' (widest glyph coverage); NFD/NFKC/NFKD or false for special needs.
outputModeNo'base64' (default) returns the PDF inline; 'file' writes it inside the PDFNATIVE_MCP_OUTPUT_DIR sandbox (SECURITY_VIOLATION when the sandbox is not configured).base64
outputPathNoRequired when outputMode='file'. Relative path inside the sandbox; must end with .pdf (no absolute paths, no '..').
paragraphsYesOrdered list of paragraphs to render in the chosen script.
typographyNoFine typography, all opt-in (omitted = unchanged bytes). kerning, fontFeatures and the 'fr' narrow space need embedFonts:true. No hyphenation dictionary is installed: use soft hyphens (U+00AD). See the typography prompt.
creationDateNoISO-8601 instant for /CreationDate (+ XMP, the trailer /ID and the {date} placeholder), written in UTC. Pin it for byte-identical output across calls and hosts; omitted = wall clock, so every call differs.
outputIntentNoCustom OutputIntent (under pdfA or pdfx): an RGB, CMYK or Gray ICC profile + condition strings, replacing the built-in sRGB intent. The profile must be a real ICC file ('acsp' signature, consistent size — PRINT_ERROR otherwise); pdfx needs device class 'prtr'. Under a CMYK / Gray intent RGB content is mapped through a calibrated default space.
footerTemplateNoRunning footer on every page. Replaces the default footer: footerText is then ignored and page numbers appear only via {page}/{pages}.
headerTemplateNoRunning header on every page (left / center / right zones); reserves 15 pt.
viewerPreferencesNoReader presentation hints (catalog /PageLayout, /PageMode, /ViewerPreferences). PDF/A-safe; all optional.
includeDiagnosticsNoReturn the diagnostics raised while building (PDFA_*, PDFX_*, TYPOGRAPHY_*) as `diagnostics[]` (possibly empty).

TDQS

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations (idempotent, non-destructive), the description discloses real behavioural traits: fonts are always embedded so `embedFonts` does not exist here, input is NFC-normalised, newlines split paragraphs, and BiDi/Arabic joining/shaping are automatic. These are non-obvious engine behaviours an agent could not derive from the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense paragraph, front-loaded with the script inventory before mechanics. Every clause carries information (script list, aliases, emoji/math, BiDi, NFC, newline behaviour), though the parenthetical script enumeration is long and could be trimmed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 23-parameter tool with an output schema, the description correctly focuses on the international-text differentiators and delegates the shared document options (PDF/A, print, metadata, creationDate) to 'as on every document tool'. That delegation assumes cross-tool documentation the agent may not have, which is the only gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already carries parameter meaning, and the description mostly restates the `lang` semantics (single code, comma list, array of mixed runs) that the schema documents in full. It adds the useful note that the tool has no `embedFonts`, but little else beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource and scope: rendering PDF text across 27 named scripts, colour emoji and math, with BiDi/shaping/normalisation details. It implicitly distinguishes itself from generate_basic_pdf by positioning this as the international/multilingual entry point, but never names that sibling explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: an agent reads the script list and infers 'use this when text is non-Latin'. There is no explicit when-to-use versus generate_basic_pdf, and no statement of what happens (or which tool to use) if the input is plain ASCII. Adequate but leaves selection to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
