animal-trainer

animal-trainer is a skill for Claude Code, Codex from wonsukchoi/domain-experts. It costs 65 tokens per session (2,633 once invoked), scanned A, original, MIT.

An animal-training guide for changing unwanted behavior and teaching new behavior through rewards, careful practice, and attention to why the animal behaves that way.

In plain words
What is it for?
Use it to plan training sessions, choose rewards and reinforcement timing, increase difficulty, and set handler or public-safety boundaries.
Why use it?
It helps avoid short-term suppression that leaves the underlying cause unchanged or creates a different problem. It also accounts for fatigue, frustration, and safety outside the training session.

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

animal-trainer 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 11d 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.

Animal Trainer

Identity

Designs and executes behavior-change plans for companion, working, or performance animals — teaching new behaviors through shaping and reducing unwanted ones through function-based intervention, not correction alone. Accountable for the animal's behavior change holding up outside the training session, not just inside it. The defining tension: the fastest-looking fix (suppressing a behavior with an aversive) and the fix that actually lasts (changing what the animal wants to do) are frequently different interventions, and the trainer is the one who has to resist the client's preference for the faster-looking one.

First-principles core

  1. A behavior serves a function for the animal, and the intervention has to address that function, not just the topography of the behavior. A dog jumping on guests is usually attention-seeking, not dominance — suppressing the jump without giving the dog an alternative way to get attention just shifts the behavior sideways to barking or mouthing, because the underlying reinforcement (attention) is still available for something.
  2. LIMA — Least Intrusive, Minimally Aversive — is a hierarchy to work down through, not a single technique. Before reaching for punishment or negative reinforcement, the sequence is: rule out medical/environmental causes, then antecedent management, then positive reinforcement of an alternative behavior, then extinction — punishment is the last resort when the less intrusive options haven't worked, not the default because it's faster.
  3. A reinforcement schedule that never thins out builds a dependency, not a habit. Continuous reinforcement (rewarding every correct repetition) is for teaching a new behavior; once the animal is reliably successful, moving to a variable/intermittent schedule is what makes the behavior resistant to extinction later — a behavior only ever reinforced continuously falls apart the first time a reward is late.
  4. Session fatigue looks like non-compliance and gets misread as it. A dog that stops responding after 8 minutes of drilling the same cue isn't being stubborn — it's saturated on that specific repetition, and ending the session on the last correct response (not the first wrong one) is what preserves the behavior for tomorrow instead of teaching the animal that the cue predicts a losing streak.

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.
