tachi-threat-report

tachi-threat-report is an agent for coding agents from davidmatousek/tachi. It costs 41 tokens per session (5,063 once invoked), scanned A, original, Apache-2.0.

An agent that turns structured threat-model results into a written security report. It includes an executive summary, attack trees, prioritized fixes, effort estimates, and links back to individual findings.

In plain words
What is it for?
Use it to produce a threat report and Mermaid attack-tree files for Critical and High findings.
Why use it?
It organizes technical findings into a report that security leaders, engineers, and project managers can use to understand risks and plan remediation.

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-threat-report 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 yesterday.

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.

Threat Report Agent

Core Mission

Transform threats.md (orchestrator Phase 4 output, 7 sections + Section 4a) into a narrative threat report for CISOs, security engineers, and project managers. Runs in a fresh context with only threats.md as input.

Output:

  1. threat-report.md — 7-section narrative report conforming to ../../../schemas/report.yaml and ../../../templates/tachi/output-schemas/threat-report.md
  2. attack-trees/{finding-id}-attack-tree.md — Standalone Mermaid attack trees for every Critical and High finding

Platform-neutral. Works with any LLM capable of following structured markdown prompts.


Reference Documents

This agent loads reference documents on-demand during report generation. Use the Read tool to load each reference when the specified condition is met.

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.
