What is dotcontext CLAUDE.md?

Repository instructions for Dotcontext, a system that connects command-line tools, a reusable runtime, an MCP server, and host integrations.

Use them when changing the CLI, runtime, MCP server, host integrations, sessions, task handoffs, or related documentation and tests.

They explain which part of the code owns each responsibility and where to find the project’s authoritative documentation and current priorities.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00458	$0.00458
Opus 5.5	$0.00183	$0.00183
Sonnet 5.5	$0.00092	$0.00092
Haiku 4.5	$0.00046	$0.00046

Security

Grade A, and why

dotcontext CLAUDE.md 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 2mo 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

Dotcontext Repository Guide

This repository is the source for the dotcontext runtime and its operator/adaptor surfaces.

Current product shape:

cli -> harness <- mcp
              <- integrations (host hooks / extensions)

Source of Truth

Start here:

README.md for product description and install guidance
dotcontext.dev (docs/) for usage guidance
ARCHITECTURE.md for runtime and boundary diagrams
CHANGELOG.md for release notes

Working Boundaries

src/cli contains operator-facing exports and CLI-oriented services (sync, MCP install, hook install, admin)
src/harness contains reusable runtime exports — domain rules, application services, and adapters
src/mcp contains the MCP transport boundary — server, gateway handlers, and schemas
src/integrations contains host hook adapters for Claude Code, Codex CLI, and Pi

Do not move domain behavior into cli, mcp, or integrations if it belongs in harness. Integrations call the harness only — they never import cli or mcp.

Current Priorities

The repository now supports:

durable harness sessions
sensors and backpressure
task contracts and handoffs
policy documents and policy evaluation
replay and failure datasets
host hook install for Claude Code, Codex CLI, and Pi
local packaging for cli, harness, mcp, integrations, and pi

Validation Commands

npm run build
npm test -- --runInBand
npm run build:packages
npm run smoke:packages

Documentation Hygiene

When changing any of the following, keep docs in sync:

product positioning
MCP install behavior
hook install behavior
package boundaries
workflow commands
release/versioning guidance

At minimum, review:

README.md
docs/src/content/docs/ (published at dotcontext.dev)
ARCHITECTURE.md
CONTRIBUTING.md
CHANGELOG.md

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.
