context-engineering-review

context-engineering-review is a cursor rule for Cursor from mohitagw15856/pm-claude-skills. It costs 106 tokens per session (1,184 once invoked), scanned A, original, MIT.

A review of everything an AI feature or agent sends to a language model for one request. It examines instructions, retrieved information, conversation history, user data, and tool definitions together.

In plain words
What is it for?
It helps inventory context, decide what to keep or remove, set token budgets, and arrange stable and changing content effectively.
Why use it?
It finds missing information, conflicting instructions, unnecessary text, and oversized requests that make the model ignore instructions, respond inconsistently, or cost more.

About the project

PM Skills is a collection of plain-Markdown instructions that teach AI assistants structured methods for handling professional, personal, and life-admin tasks. People use it with Claude, ChatGPT, Gemini, Cursor, Codex, and other supported agents for work such as writing product requirements, reviewing documents, or planning difficult situations.

Token cost

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.

Security

Grade A, and why

context-engineering-review 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 7d 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.

Context Engineering Review Skill

Most agent failures aren't model failures — they're context failures: instructions buried under retrieval dumps, stale history contradicting fresh facts, twelve tool definitions the task never needed. This skill audits the assembled window, not just the prompt text.

What This Skill Produces

  • A context inventory: every component in the window, its size, and who put it there
  • A keep / cut / restructure verdict per component, with the reasoning
  • Ordering and cache-alignment fixes (stable prefix first, volatile content last)
  • A token budget per component with an enforcement point

Required Inputs

Ask for (if not already provided):

  • A real assembled context — an actual logged request (system prompt + messages + tools), not the template. If only the template exists, review that but flag that dynamic bloat is invisible
  • The failure or goal — ignoring instructions? too expensive? inconsistent? slow?
  • What varies per request (retrieval, history, user data) vs. what is static
  • The model and its context limit, and current typical request size

Review Method

1. Inventory. List every component in window order: system prompt sections, tool definitions, retrieved documents, conversation history, few-shot examples, injected state. For each: token count (estimate if unlogged), static vs. dynamic, and owner.

2. Interrogate each component:

  • Earning its tokens? Would removing it change outputs on real traffic? The honest test is ablation, not intuition.
  • Right form? Raw dumps (full HTML, whole files, unabridged history) almost always beat down to summaries, excerpts, or references the agent can expand via a tool.
  • Right position? Instructions that must win go in the system prompt; volatile data goes late; nothing critical hides in the middle of a long window.
  • Fighting anything? Contradictions between sections (persona says terse, examples are verbose; old history asserts what retrieval now refutes) are the classic "ignores instructions" root cause.

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.
