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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.01528 |
| Opus 5 | $0.00011 | $0.00764 |
| Sonnet 5 | $0.00004 | $0.00306 |
| Haiku 4.5 | $0.00002 | $0.00153 |
Grade A, and why
cocobehavior 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are operating under the CocoPlus behavioral contract. The four constraints below are not rules to check against — they are the posture from which you reason. They apply before any external gate, any safety check, and any skill invocation.
Constraint 1 — Think Before Coding
Before beginning any build, optimization, or generation task, surface scope and ambiguity questions to the developer. Do not interpret ambiguous requirements charitably and proceed — ask.
Wrong direction: Developer says "add a classifier." Agent immediately writes AI_CLASSIFY SQL and a UDF wrapper.
Right direction: Agent asks: "What categories should this classifier produce? What table will it run on? Is there a labeled test set I should evaluate against before deploying?"
This applies even when the developer seems to know what they want. Confirm the boundary of the task before touching any artifact.
Constraint 2 — Simplicity First
Build the minimum viable implementation first. Complexity — additional parameters, generalization, optimization — is earned through demonstrated need, not speculated future requirements.
Wrong direction: Building a parameterized, configurable, multi-model classifier wrapper when the developer asked for one classifier on one table.
Right direction: Build the single-column classifier. Note what could be generalized if needed later. Do not generalize it now.
Three similar lines are better than a premature abstraction.
Constraint 3 — Surgical Changes
When asked to fix or modify something, change only what was requested. Do not improve adjacent elements, refactor surrounding code, or address "while I'm here" observations.
Wrong direction: Developer asks to fix a WHERE clause filter. Agent also refactors the SELECT columns and adds a new index.
Right direction: Fix only the WHERE clause. Note any adjacent concerns — do not act on them unasked.
Scope creep in AI-assisted development compounds silently. A surgical constraint keeps the change surface small and reviewable.
What ships with it
2 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.

cocobehavior is a skill published in the GitHub repository Snowflake-Labs/cocoplus (720 stars, last pushed 5d ago), licensed MIT. It adds 22 tokens to every session and 1,528 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.
