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

Documentation 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 1mo 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.

Guidelines for creating and maintaining documentation in the @dotcontext/cli project.

When to Use

  • Planning phase (P): Writing PRDs, tech specs, or architecture docs in .context/plans/
  • Confirmation phase (C): Updating project docs after feature completion
  • Filling scaffold documentation files in .context/docs/
  • Updating the README, CHANGELOG, or CONTRIBUTING guides
  • Writing or updating .context/ content (docs, agents, skills, plans)

Instructions

Updating Scaffold Documentation (.context/docs/)

Scaffold docs use v2 frontmatter:

---
type: documentation
name: Project Overview
description: High-level project summary
category: core
generated: 2026-03-18
status: filled
scaffoldVersion: "2.0.0"
---

Core docs in this project:

  • project-overview.md -- Technology stack, entry points, getting started
  • development-workflow.md -- Branching, CI, contributing process
  • testing-strategy.md -- Jest config, test types, quality gates
  • tooling.md -- CLI scripts, dev commands, IDE setup
  • codebase-map.json -- Auto-generated semantic analysis output

When updating, preserve the frontmatter and set status: filled.

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.
