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 | $0.00054 | $0.03280 |
| Opus 5 | $0.00027 | $0.01640 |
| Sonnet 5 | $0.00011 | $0.00656 |
| Haiku 4.5 | $0.00005 | $0.00328 |
Grade A, and why
coding scanned grade A with 1 finding 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 4d 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.

Coding Agents
Money-Making Overview
| Agent | Revenue Impact | Avg. Savings | Best For |
|---|---|---|---|
| Linter Agent | Enforces standards at scale | $300–1,000/project | Bulk rule application, migration, cleanup |
| Perf Agent | Cuts infra costs 20–40% | $2,000–20,000/year | Bottleneck profiling, query tuning, cost reduction |
| Refactor Agent | Reduces maintenance debt 50% | $3,000–15,000/refactor | Complexity reduction, modernization, splitting monoliths |
| Security Agent | Prevents P1 production incidents | $5,000–50,000/incident | Bug bounty, vulnerability scanning, pentest automation |
| Test Agent | Cuts regression bugs 80% | $2,000–8,000/release | Coverage gaps, regression tests, e2e flows |
Combined ROI: A single pass through all five agents on a medium codebase (50K LOC) saves $15,000–50,000 by preventing production bugs, reducing cloud costs, and slashing maintenance overhead.
When to Use
Linter first — before every PR, after merge conflicts, when adopting new rules, migrating linters.
Perf when it hurts — app is slow, memory is growing, queries lag, infra costs too high, capacity planning.
Refactor before features — make the change easy before making the easy change. High cyclomatic complexity, duplicated code, monolithic files.
Security before deploy — every commit touching auth, payments, PII, or external APIs requires a security gate.
Test always — new features (TDD), regression tests for bugs, coverage gaps, integration tests, e2e.
When NOT to Use
- Trivial one-liner changes — just make the edit.
- Real-time human judgment — agents cannot decide product or business trade-offs.
- Agent lacks access to required tools, credentials, or data.

What ships with it
5 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.

coding is a skill published in the GitHub repository oyi77/1ai-skills (12 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 3,280 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
plugin-test
为 Zhin.js 插件编写和运行测试（Plugin Runtime）。Use when asked to write tests, add test coverage, or verify defineCommand / definePlugin behavior. 引导编写符合 Runtime 的 Vitest 测试。.
building
Install dependencies and run the test/lint/typecheck gate for a change inside the sandbox — package-manager detection, install-first, and (when implementing) TDD discipline. Use when implementing, fixing, or verifying code in a pre-cloned repo.
code-reviewer
Code review specialist focused on patterns, bugs, security, and performance.
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.
