09-context-discipline

09-context-discipline is a cursor rule for coding agents from Haroon966/pinky-cursor. It costs 249 tokens per session, scanned A, original, MIT.

A set of working rules for keeping an agent's attention on only the files relevant to the current request.

In plain words
What is it for?
It guides file selection, skill loading, search habits, and short responses during coding work.
Why use it?
It prevents the agent from filling its working context with unrelated documentation, which can waste tokens and distract from the task.

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

09-context-discipline 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 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.

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

Context discipline (ALWAYS ON)

Pinky rules stay always on until the user opts out. Skills are available by default — but do not load everything into context.

Do

  • Read / open only files needed for this user prompt.
  • For skills: load one matching SKILL.md (and its companions only if that skill says so). Never bulk-read all of skills/.
  • Prefer search/grep over opening whole trees.
  • Keep replies Caveman-short so tokens stay low.

Don't

  • Don't preload every Pinky skill, format doc, or rule file "just in case".
  • Don't dump ADR-FORMAT.md / CONTEXT-FORMAT.md unless running /grill-with-docs.
  • Don't attach the whole kit README/INSTALL into every turn after install.

Opt out

User says "stop caveman", "normal mode", "don't use pinky", "disable [skill/rule]" → stop that layer for the session (or until they re-enable).

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.
