Context Engineering Kit is a collection of skills, agents, hooks, instructions, commands, and plugins that shape how coding agents use context and carry out development work. It is for developers using Claude Code and other supported coding agents who want more predictable results. The catalogue entries are components from this collection.
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 | $0.00030 | $0.01048 |
| Opus 5 | $0.00015 | $0.00524 |
| Sonnet 5 | $0.00006 | $0.00210 |
| Haiku 4.5 | $0.00003 | $0.00105 |
Grade B, and why
change-expectation-agent scanned grade B 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 5d 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
CRTIICAL: Do not launch any agents, not use any skills, not stage or stash changes, do not commit anything, do not run any commands. Do not run tests/lint/build/etc. If you will do anything from that, you will be killed The source is not reproduced here

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.

change-expectation-agent is an agent published in the GitHub repository NeoLabHQ/context-engineering-kit (1,522 stars, last pushed 8d ago), licensed GPL-3.0. It adds 30 tokens to every session and 1,048 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other agents, from other repositories
builder
Turn shot-plan.json into one renderable HyperFrames composition (compositions/index.html). Everything stays in the HF ecosystem — HTML is the source of truth; a single paused GSAP timeline carries all motion; the engine seeks it. Category-specific build rules live in categories/ /module.md; this file is the shared…
planner
Plan execution: turn approved intent/specs into a sequenced plan scaled to size. Full subagent.
explorer
Use INSTEAD OF the built-in Explore agent for any "where is X / which files do Y / how is Z wired" question in this repo. Returns file paths and one-line excerpts, never file dumps. Read-only. Unlike Explore it already knows this monorepo's layout, its boundary rules, and which paths are deny-listed, so it does not…
bundle-analyzer
Use PROACTIVELY when asked about frontend bundle size, chunk splitting, what is making the build large, whether a dependency is worth adding, or before a performance change to front-app. Runs the existing analyze script and returns ONLY a ranked chunk summary - the verbose per-module build output stays out of the main…
quality-gatekeeper-agent
Agent "quality-gatekeeper-agent" from OpenRaiser/PaperFit, covering quality gatekeeper agent, 角色定位, 第一验收顺序, 主责范围 and 非职责范围.
agent builder
You must fully embody this agent's persona and follow all activation instructions exactly as specified. NEVER break character until given an exit command.
