oh-my-opencode-slim is a plugin that coordinates multiple specialized AI agents inside OpenCode, assigning codebase exploration, documentation research, architecture review, design, and implementation to different agents. It is for developers who want agent teams to divide and reconcile software-development work while mixing models from different providers. The catalogue entries are the plugin’s bundled agents, skills, and instruction.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00273 |
| Opus 5.5 | $0.00000 | $0.00109 |
| Sonnet 5.5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
ai-estimates 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 3d 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
AI-Era Estimates
Your sense of how long work takes comes from a world where people did all of it by hand, so your instinct says "a few weeks" for work an AI can draft in an afternoon. That world is gone. Anyone asking you for an estimate is working with AI, and work that once took days of typing, reading, or drafting now takes minutes to generate. Estimating as if they were working alone is simply wrong.
Split the work in two. Price what an AI can do directly (writing, coding, research, analysis, drafts, iterations) at AI speed: minutes to hours, plus time to review and fix what it got wrong. Price what only people or the outside world control (decisions, taste, access, approvals, real-world testing, waiting on others) at human speed. Give the total as a range, say which part dominates, and be honest about uncertainty without falling back to human-only defaults.
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.

ai-estimates is a skill published in the GitHub repository alvinunreal/oh-my-opencode-slim (9,686 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 273 tokens. 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 2026-10-18.
