pynchy AGENTS.md

Repository instructions for Pynchy, a personal Claude assistant, covering its architecture, deployment concerns, conventions, and important files.

In plain words
What is it for?
Use them when developing or reviewing Pynchy, especially changes crossing modules or packages. They point to the architecture and conventions that should guide the work.
Why use it?
They help coding assistants change the project without violating its intended package ownership, public interfaces, or modular-monolith design.

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

pynchy AGENTS.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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pynchy

Personal Claude assistant. See README.md for philosophy. See installation guide for installation. See architecture for architecture. See CONVENTIONS.md for design principles (composition over inheritance, parse-don't-validate, semantic types, code/doc coupling) — apply them when writing or reviewing code.

Architectural Direction

Pynchy's architectural ambition is a modular monolith with semantic domain contracts, use-case-owned ports, concrete adapters, and explicit composition roots—not a distributed-services or dependency-injection-framework rewrite. Before changing a cross-subsystem dependency, read the service boundary guide. Treat architecture.toml as the executable source of truth for current package ownership, public surfaces, and allowed role dependencies.

Burn down architecture-baseline.toml package by package. For each multi-module package with cross-package consumers, migrate its sole public surface to <package>.api; a façade made entirely of curated re-exports is valid. Move all consumers in the package pass, update public_modules, and remove every stale baseline entry. Correct package roles when direction is wrong. Do not weaken the policy or regenerate the baseline merely to reduce the count.

Deployment Awareness

You are usually NOT running on the production host. The live host is deployment-specific and should come from local memory, environment, or the operator, not from public repo defaults. Before making changes that affect the live service (config.toml, server-side files, service restarts), read the pynchy-ops skill for deployment procedures, auto-deploy behavior, and how to observe the running service.

Quick Context

Python process that connects to messaging channels (WhatsApp, Slack, etc. via plugins), routes messages to Claude Agent SDK running in containers (Apple Container on macOS, Docker on Linux). Each group has isolated filesystem and memory.

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.

pynchy AGENTS.md is an instructions file published in the GitHub repository crypdick/pynchy (10 stars, last pushed 7d ago), licensed MIT. It adds 1,705 tokens to every session, about $0.0085 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
