tachi: Skill for Claude Code

.claude/skills/tachi-report-assembly/SKILL.md

tachi-report-assembly is a skill for Claude Code from davidmatousek/tachi. It costs 58 tokens per session (465 once invoked), scanned A, original, Apache-2.0.

A set of rules for assembling a PDF security assessment from existing files. It detects available findings, extracts their data, adds brand assets, and prepares the information for a Typst document template.

In plain words
What is it for?
Use it to detect report artifacts, generate Typst data bindings, resolve logos and image paths, and build a multi-page security report.
Why use it?
It standardizes how scattered security-analysis outputs become a complete report and chooses the richest available findings data.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

tachi-report-assembly 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 7d ago.

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.

tachi-report-assembly

PDF security report assembly domain knowledge extracted from the tachi report-assembler agent. This skill provides the artifact detection tables, Typst template interface contract, and brand asset guidelines that the report-assembler uses to transform pipeline artifacts into a professional PDF security assessment booklet.

Domain Overview

The report assembly pipeline bridges tachi pipeline artifacts (markdown and image files) with a Typst template system to produce a multi-page PDF:

  1. Artifact Detection -- Identify which pipeline outputs are available in the target directory and select the richest data source tier for findings presentation
  2. Data Extraction -- Parse markdown artifacts and extract structured data via deterministic Python script
  3. Typst Data Generation -- Generate a report-data.typ file containing all extracted variables as Typst #let bindings that the template system imports at compile time
  4. Brand Asset Resolution -- Locate logo files with dark variant support and compute relative paths for Typst image inclusion

The Typst template system uses a data injection pattern: main.typ imports report-data.typ and conditionally includes page templates based on artifact availability flags. The agent's responsibility is generating report-data.typ with correct variable names, types, and values.

Loading Table

Reference files are loaded on-demand by the report-assembler agent at specific workflow phases using the Read tool.

Reference File Load When
Typst Artifacts references/typst-artifacts.md Artifact detection phase (Step 1) — determining which pipeline outputs exist and selecting data source tier
Typst Template Contract references/typst-template-contract.md Data generation phase (Step 2) — generating report-data.typ with correct variable bindings
Brand Asset Guidelines references/brand-asset-guidelines.md Brand detection phase (Step 2) — locating and resolving logo paths for cover and footer

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.
