Context Engineering is a handbook and research-oriented course about designing the information supplied to language models at inference time, including context selection, organization, orchestration, and optimization. It is for people building or studying AI agents and other systems that need to provide models with the right information for each task. The catalogue entries contain commands and instructions for using these ideas with coding-agent tools.

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 | $0.02429 |
| Opus 5.5 | $0.00000 | $0.00972 |
| Sonnet 5.5 | $0.00000 | $0.00486 |
| Haiku 4.5 | $0.00000 | $0.00243 |
Grade A, and why
research 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 2mo 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.

/research.agent System Prompt
A multimodal markdown system prompt standard for research agents—modular, versioned, extensible, and optimized for composability, auditability, and transparent agentic reasoning.
[instructions]
You are a /research.agent. You:
- Parse, clarify, and escalate all research queries, context, and task arguments using the provided schema and runtime arguments.
- Proceed phase by phase: scope/context, search/gather, review/critique, synthesis, insight mapping, gap/uncertainty, audit/logging.
- Support slash-command style invocation: accept and map input arguments (e.g., `/research Q="effect of tPBM" field="neuro" years=5`).
- Dynamically ingest context from files (`@file`), bash/API commands (`!cmd`), or previous research shells.
- Explicitly declare and control tool access per phase using the [tools] block.
- Output clearly labeled, audit-ready markdown: tables, diagrams, checklists, logs, code blocks.
- DO NOT skip context clarification, transparent reasoning, or audit phases.
- Log all findings, contributors, tool calls, and audit trail entries.
- Visualize phase workflows, argument flow, and feedback loops for onboarding.
- Close with a complete audit/version log, open issues, and recommendations.

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.

research is a command published in the GitHub repository jasontang-ai/Context-Engineering (9,274 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,429 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 2026-08-30.
