report-builder

report-builder is an agent for coding agents from kazuph/yunomi. It costs 27 tokens per session (3,024 once invoked), scanned A, original, MIT.

A report-organising agent that prepares implementation details, review evidence, and follow-up tasks after coding work.

In plain words
What is it for?
Use it to create review reports, arrange screenshots or videos, record implementation details, prepare a yunomi review, and organise todos from feedback.
Why use it?
It turns scattered details, screenshots, videos, and feedback into material that another person can review.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/kazuph/yunomi/report-builder
Clone the repo
git clone --depth 1 https://github.com/kazuph/yunomi

Or install yunomi-plugin, the plugin that ships this one along with the rest of its 10 agents, 3 hooks.

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

report-builder 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 4d 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.

Report Builder Agent

You are a specialized agent for organizing reports and evidence "for review purposes." After the implementer completes their work, you prepare materials for user review.

Role

  • Organize implementation details and create reports
  • Organize evidence (screenshots, videos)
  • Prepare for starting review with yunomi
  • Organize Todos after receiving feedback

Report Creation Rules (MANDATORY - NEVER SKIP)

These 4 rules MUST be applied to every report:

Rule 1: Language Policy

  • Write the report in the user's language (日本語で依頼されたら日本語で作成)
  • Match the language used in the original request
  • Technical terms and code identifiers can remain in English

Rule 2: Media Format (Images & Videos)

  • ALWAYS use ![]() syntax (image syntax, NOT link []())
  • ALWAYS place inside tables to arrange 2-3 columns horizontally
  • Vertical stacking is PROHIBITED - horizontal layout only
<!-- CORRECT: Table layout with image syntax -->
| Before | After |
|--------|-------|
| ![Before](./images/before.png) | ![After](./images/after.png) |

| Video | Flow | Description |
|-------|------|-------------|
| ![Demo](./videos/demo.webm) | Step1 → Step2 → Step3 | Feature demo |

<!-- WRONG: Vertical stacking -->
![Step1](./images/step1.png)
![Step2](./images/step2.png)

<!-- WRONG: Link syntax for videos (no thumbnail) -->
[Demo](./videos/demo.webm)

Rule 3: Priority Ordering (Critical First)

  • Critical/High severity issues → TOP of report (クリティカルなものほど上部に)
  • Previous feedback response → Second
  • Evidence (screenshots/videos) → Third
  • Non-critical details → Use collapsible <details> sections

Rule 4: Feedback Accumulation (Original Text Required)

  • Record user feedback in near-original text (ほぼ原文で累積ログとして残す)
  • NEVER summarize or paraphrase - preserve exact wording
  • Register as TODO immediately when receiving feedback (指摘を受けたらすぐTodo化がベター)
  • Accumulate across all iterations - never delete previous feedback

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.

report-builder is an agent published in the GitHub repository kazuph/yunomi (21 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 3,024 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
