project-context

A project-context rule that records a codebase's purpose, technology stack, conventions, fixed decisions and release checks. It gives the coding agent stable background information for work in that project.

In plain words
What is it for?
Use it to document how a project works, where secrets belong, which decisions are fixed and which checks must pass before release.
Why use it?
It reduces repeated explanations and helps keep changes consistent with the project's existing choices and safety rules.

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.

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

project-context scanned grade A 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 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.

What it actually says

{{PROJECT_NAME}}: project context

Template. Fill every {{PLACEHOLDER}} from THIS codebase (the bootstrap does this by exploring the repo). The stable method is in @.cursor/rules/operating-method.mdc.

What this project is

{{One-paragraph description: what it does, who it's for, current state. Replace this block.}}

Stack

{{Languages, frameworks, DB, infra, key services. Where secrets live (and that they're never committed). Any non-obvious build/deploy step.}}

Coding standards

{{Project conventions. Examples: error-handling norms; no hardcoded secrets + maintain .env.example; destructive ops only via the approved safe path; one logical change per commit; honest user-facing positioning.}}

Pre-ship gates

{{Each gate = a live check returning a count with an explicit pass condition. Seed: post-change live curl/query; consumer-route audit after an API/shape change; verify any hardcoded threshold against a live distribution before shipping.}}

Locked decisions: do not relitigate

Rule: if a new idea conflicts with a decision below, report it as a deferred option; do not implement by default. "Looks ready" is not the trigger; the documented condition must be met.

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.

project-context is a cursor rule published in the GitHub repository Sharrmavishal/operating-kit (2 stars, last pushed 1mo ago), licensed MIT. It adds 343 tokens to every session, about $0.0017 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
