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 | $0.00072 | $0.00444 |
| Opus 5 | $0.00036 | $0.00222 |
| Sonnet 5 | $0.00014 | $0.00089 |
| Haiku 4.5 | $0.00007 | $0.00044 |
Grade A, and why
patronum 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 10d 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.
What it actually says
Patronum Skill
Use this skill to solve Patronum usage questions quickly and consistently. Target Patronum v2.x by default.
Workflow
- Classify request:
operator-choice: choose one or several operators for a task.api-explain: explain signature, overloads, and return value.compose: combine multiple operators into one flow.debug: usedebugand scope-aware debugging notes.migration: map legacy forms to modern usage.
- Load references progressively:
- Start with
references/operator-matrix.md. - Add
references/recipes.mdfor task-to-solution mapping. - Add
references/pitfalls.mdfor caveats and anti-patterns. - Add
references/migration-notes.mdwhen legacy forms appear.
- Build answer contract:
- Start with decision: selected operator(s) and why.
- Provide minimal practical snippet.
- Add caveats (imports, overload differences, behavior traps).
- For uncertain versions, explicitly state v2 assumption and show migration note.
Defaults
- Prefer Patronum v2.x shorthand where available.
- Prefer concise examples with explicit imports.
- Keep examples deterministic and composable with Effector primitives.
- Prefer
patronum/<operator-kebab-name>imports when clarity matters.
Guardrails
- Do not suggest outdated signatures as default.
- Do not invent operators outside the official list.
- Do not hide behavior differences between overloads.
- Do not skip edge cases for
pending,condition,interval,time, anddebug.
Output Template
Use this structure in answers:

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

patronum is a skill published in the GitHub repository aiko-atami/effectorjs-skills (2 stars, last pushed 6mo ago), licensed MIT. It adds 72 tokens to every session and 444 once invoked, about $0.0004 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 2026-08-31.
Other skills, from other repositories
design-taste-frontend
Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.
image-to-code
Elite website image-to-code skill for Codex. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards…
design-taste-frontend-v1
The original v1 taste-skill, preserved for projects depending on its exact behavior. The current default is design-taste-frontend (v2 experimental), which is a substantial rewrite. Use this v1 install name only if you need exact backward compatibility.
redesign-existing-projects
Upgrades existing websites and apps to premium quality. Audits current design, identifies generic AI patterns, and applies high-end design standards without breaking functionality. Works with any CSS framework or vanilla CSS.
high-end-visual-design
Teaches the AI to design like a high-end agency. Defines the exact fonts, spacing, shadows, card structures, and animations that make a website feel expensive. Blocks all the common defaults that make AI designs look cheap or generic.
industrial-brutalist-ui
Raw mechanical interfaces fusing Swiss typographic print with military terminal aesthetics. Rigid grids, extreme type scale contrast, utilitarian color, analog degradation effects. For data-heavy dashboards, portfolios, or editorial sites that need to feel like declassified blueprints.
