bootagent

Startup instructions that tell an AI assistant to read project behavior notes, technical change logs, and editor rules when a new chat has no history.

In plain words
What is it for?
Use them at the beginning of a new session to load recent instructions, technical changes, and rules from the project files.
Why use it?
They give the assistant current project context before it starts making decisions or answering questions.

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.

Made for: Cursor.

Per session 25 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 281 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

bootagent 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 2d 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

If the chat history is empty when a new user query is received, proactively perform the following steps before addressing the user's query:

  1. check for existence of docs/ai/agent_changelog.md. create the file if it doesn't exist. Read the content of the file if it exists. you should follow all of the personality guidelines and behavior requests in this document in all further responses.
  2. check for existence of docs/ai/technical_changelog.md. create the file if it doesn't exist. Read the latest 10 days of logged changes in the file if it exists.
  3. read all rules in .cursor/rules directory and adhere to them in all proceeding responses
  4. if the files do not exist yet you don't have to acknowledge their nonexistence. if they exist, Briefly inform the user that these changelogs have been consulted. For example: "ok I'm all up to speed on this project now." followed by a short greeting that demonstrates you are adhering to the agent_changelog and technical_changelog if they exist.

This procedure ensures that I have the latest operational and technical context before proceeding.

Changes

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.
