Add table / report

add_table

Idempotent

Render headers and rows into a paginated PDF table report with wrap, repeated headers, zebra rows and PDF/A or print-ready output.

Instructions

Tabular PDF report from headers + rows (every row the same length). Smart-table options: wrap, repeatHeader (header on every page), zebra, caption (tagged for PDF/A), minRowHeight, cellPadding, cellBorders, cellVAlign, autoFitColumns, clipCells. Inside a longer document use a 'table' block of generate_basic_pdf instead. PDF/A (pdfA + embedFonts:true), print, metadata, watermark and creationDate options as on every document tool.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`pdfA`	No	PDF/A level: pdfa1b (simple text+images), pdfa2b/pdfa2u (richer; 2u = Unicode mapping), pdfa3b (attachments / Factur-X). Pair with embedFonts=true for a valid claim. Exclusive with encryption. See docs/guides/PDFA.md.
`pdfx`	No	PDF/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.
`rows`	Yes	Data rows. Each row is an array of cell strings with the same length as `headers`.
`wrap`	No	Cell wrap policy: 'auto' (default) wraps only overflowing cells; 'always' wraps every cell; 'never' truncates.
`debug`	No	Draw margin / block / cell guide rectangles (unmarked content — not for PDF/UA output). Geometry unchanged. Default false.
`print`	No	Print 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.
`title`	Yes	Report title rendered at the top of the document and used as PDF metadata title.
`zebra`	No	Alternate-row light tint (static fill, PDF/A-1b safe).
`strict`	No	Fail 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.
`caption`	No	Caption rendered above the table (tagged as /Caption under PDF/A).
`encrypt`	No	Encrypt 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.
`headers`	Yes	Column header labels. Must have the same length as each row in `rows`.
`margins`	No	Margins in points, all four required (0–200). Default 45 / 36 / 35 / 36.
`compress`	No	FlateDecode the streams (smaller file, different bytes; PDF/A unaffected, XMP stays plain). Default false.
`metadata`	No	/Info (+ XMP under PDF/A): author, subject, keywords, /Trapped.
`pageSize`	No	Portrait 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.
`clipCells`	No	Clip cell contents to the column bounds (PDF clip operators). Recommended for PDF/A and visual safety.
`infoItems`	No	Optional key-value metadata rows rendered below the title (e.g. date, author).
`watermark`	No	Optional semi-transparent watermark rendered centred on every page: `text` (e.g. 'DRAFT'), `image` (JPEG/PNG), or both combined. At least one of text / image is required. opacity < 1.0 (text or image, including the defaults) is rejected under pdfA='pdfa1b' (ISO 19005-1 forbids transparency).
`cellVAlign`	No	Vertical alignment of cell content.
`embedFonts`	No	Embed Noto Sans Latin instead of the viewer base-14 Helvetica. REQUIRED for a valid PDF/A or PDF/X claim (every font embedded) and for strict=true; adds ~0.3 MiB.
`footerText`	No	Optional text rendered at the bottom of every page.
`outputMode`	No	Either 'base64' (returns the PDF inline) or 'file' (writes to a sandboxed path inside PDFNATIVE_MCP_OUTPUT_DIR).	base64
`outputPath`	No	Required when outputMode='file'. Relative path inside the sandbox; must end with .pdf.
`typography`	No	Fine 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.
`cellBorders`	No	Per-cell vector borders (pure strokes, PDF/A-safe). Choose individual sides or `all`.
`cellPadding`	No	Horizontal cell padding in points (default 3).
`creationDate`	No	ISO-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.
`minRowHeight`	No	Minimum row height in points (default 12).
`outputIntent`	No	Custom 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.
`repeatHeader`	No	Repeat the header row on every continuation page (default true).
`autoFitColumns`	No	Auto-fit column widths to content. Output bytes then depend on text metrics (not byte-deterministic across content changes).
`footerTemplate`	No	Running footer on every page. Replaces the default footer: footerText is then ignored and page numbers appear only via {page}/{pages}.
`headerTemplate`	No	Running header on every page (left / center / right zones); reserves 15 pt.
`viewerPreferences`	No	Reader presentation hints (catalog /PageLayout, /PageMode, /ViewerPreferences). PDF/A-safe; all optional.
`includeDiagnostics`	No	Return the diagnostics raised while building (PDFA_, PDFX_, TYPOGRAPHY_*) as `diagnostics[]` (possibly empty).

Output Schema

TableJSON Schema

Name	Required	Description
`mode`	Yes
`summary`	No	Tool-specific summary, when produced.
`filePath`	No	Sandboxed absolute path (file mode).
`sizeBytes`	Yes
`diagnostics`	No	Engine diagnostics (when includeDiagnostics=true).

TDQS

A4.1/5.0

Behavior5/5

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

Though annotations declare non-readOnly/non-destructive, the description adds substantial behavioral context beyond them: embedFonts adds ~0.3 MiB, creationDate omission causes byte-differences across calls while pinning it gives deterministic output, and autoFitColumns makes output non-byte-deterministic. These are non-obvious traits that meaningfully inform invocation.

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?

Front-loaded with the core purpose and constraint in the opening sentence, followed by the alternative routing and a compact option summary. Given 36 parameters, the length is justified, though the option-name enumeration is somewhat redundant with the schema.

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?

An output schema exists, so return values need no explanation. The description covers purpose, the sibling alternative for longer documents, and PDF/A pairing; with 100% schema coverage the remaining parameter detail is delegated appropriately. Some behavioral nuance could still be richer, but it is complete enough to call correctly.

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 the parameter semantics. The description's smart-table option list (wrap, repeatHeader, zebra, caption, etc.) largely restates what the schema documents, adding only marginal value over the structured fields.

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 first sentence gives a specific verb-resource pairing ('Tabular PDF report from `headers` + `rows`') with a concrete constraint (rows the same length), and later names the sibling alternative (generate_basic_pdf's 'table' block) for longer documents. It is clear, though the core purpose arrives without an explicit action verb and is partly buried under the feature enumeration.

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

Usage Guidelines4/5

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

It gives an explicit routing condition: 'Inside a longer document use a "table" block of generate_basic_pdf instead,' which tells the agent when to prefer the sibling. It also notes 'Pair with embedFonts=true for a valid PDF/A claim.' No explicit when-not/exclusion list beyond these, but the context is clear.

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