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 | $0.00041 | $0.00826 |
| Opus 5 | $0.00020 | $0.00413 |
| Sonnet 5 | $0.00008 | $0.00165 |
| Haiku 4.5 | $0.00004 | $0.00083 |
Grade C, and why
constitution-validator scanned grade C with 2 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 today.
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.

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.

constitution-validator is an agent published in the GitHub repository wildcard/caro (37 stars, last pushed yesterday), licensed AGPL-3.0. It adds 41 tokens to every session and 826 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.

design-review
Expert design reviewer for web UI. Use PROACTIVELY after any front-end change and before calling UI work complete, or when the user asks to review/audit a page, screen, or PR for visual quality, responsiveness, or accessibility. Drives a real browser (Playwright MCP) across viewports, checks WCAG 2.1 AA, and returns…
docs-auditor
Weekly standing patrol for docs drift vs code, broken links, index consistency, and i18n lag reporting (which locales are behind English and by how much). Patrols for progressive-disclosure violations doc-writer may have missed.
retrospective-miner
Weekly standing patrol that mines telemetry — prunes never-consulted assets, recalibrates time-boxes, reclassifies "other" failures, and mines primitive candidates (duplicated code shapes, repeated raw hackage imports) into triager-fed issues.
seneschal
The project's strategic pairing agent (Yegge's Seneschal). Nick invokes it inside this repo, one task at a time, for design/strategy work — docs IA, website design system, architecture decisions, roadmap shaping. It does not implement; its deliverables are specs/ADRs/issues fed into the queue.
skill-designer
Designs and maintains the user-facing skills NeoHaskell ships. Every skill change is verified by actually running the skill against the current release (its area verifier). Persona skill-author.
ui-reviewer
Visual QA against the design spec for website changes (verify phase) — cross-locale layout sanity, accessibility basics. Every visual change attaches before/after Playwright screenshots to the PR; the pr-ready checker blocks without them.
