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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.01108 |
| Opus 5 | $0.00022 | $0.00554 |
| Sonnet 5 | $0.00009 | $0.00222 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
build-review-interface 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 6d 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.
This is a copy
100% identical to build-review-interface — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Build a Custom Annotation Interface
Overview
Build an HTML page that loads traces from a data source (JSON/CSV file), displays one trace at a time with Pass/Fail buttons, a free-text notes field, and Next/Previous navigation. Save labels to a local file (CSV/SQLite/JSON). Then customize to the domain using the guidelines below.
Data Display
Format all data in the most human-readable representation for the domain. Emails should look like emails. Code should have syntax highlighting. Markdown should be rendered. Tables should be tables. JSON should be pretty-printed and collapsible.
- Collapse repetitive elements. If every trace shares the same system prompt, put it in a
<details>toggle. - Extract and surface key metadata. If traces contain a property name, client type, or session ID buried in the data, extract it and display it prominently as a header or badge.
- Color-code by role or status. Use left-border colors to distinguish user messages, assistant messages, tool calls, and system prompts at a glance.
- Group related elements visually. Tool calls and their responses should be visually linked (indentation, shared border).
- Collapse what doesn't help judgment. Verbose tool response JSON, intermediate reasoning steps, and debugging context go behind toggles.
- Highlight what matters most. Make the primary content reviewers judge visually dominant. Bold key entities (prices, dates, names). Use font size and spacing to create hierarchy.
- Show the full trace. Include all intermediate steps (tool calls, retrieved context, reasoning), not just the final output. Collapse them by default but keep them accessible.
- Sanitize rendered content. Strip raw HTML from LLM outputs before rendering. Disable images in rendered markdown if they could be tracking pixels.
Feedback Collection
Annotate at the trace level. The reviewer judges the whole trace, not individual spans.
- Binary Pass/Fail buttons as the primary action.
- Free-text notes field for the reviewer to describe what went wrong (or right).
- Defer button for uncertain cases.
- Auto-save on every action.
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.

build-review-interface is a skill published in the GitHub repository marchatton/agent-skills (5 stars, last pushed 6mo ago), licensed MIT. It adds 43 tokens to every session and 1,108 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to build-review-interface, differing in 0 lines, and is treated as a copy.
