What is TinkerTasker CLAUDE.md?

A project guide for TinkerTasker, an application split between AI services and a command-line interface. It explains the code layout and design rules for keeping the implementation small.

Use it when reading, designing, or modifying TinkerTasker code, especially across its AI-core and command-line components.

It gives a coding agent the project context needed to make changes that fit the existing structure. This reduces unnecessary abstractions and avoids building for requirements that do not exist.

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	$0.01000	$0.01000
Opus 5.5	$0.00400	$0.00400
Sonnet 5.5	$0.00200	$0.00200
Haiku 4.5	$0.00100	$0.00100

Security

Grade A, and why

TinkerTasker 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.

Project Structure

TinkerTasker is broken up into two main components: ai-core: Contains the core AI functionality, including the MCP servers for filesystem and web. This is the pyproject.toml for the package @./ai-core/pyproject.toml

cli-ux: Provides the command-line interface for interacting with TinkerTasker. This is the pyproject.toml for the package @./cli-ux/pyproject.toml

Core Design Principles

Ruthless Simplicity

KISS principle taken to heart: Keep everything as simple as possible, but no simpler
Minimize abstractions: Every layer of abstraction must justify its existence
Start minimal, grow as needed: Begin with the simplest implementation that meets current needs
Avoid future-proofing: Don't build for hypothetical future requirements
Question everything: Regularly challenge complexity in the codebase

Architectural Integrity with Minimal Implementation

Preserve key architectural patterns: MCP for service communication, SSE for events, separate I/O channels, etc.
Simplify implementations: Maintain pattern benefits with dramatically simpler code
Scrappy but structured: Lightweight implementations of solid architectural foundations
End-to-end thinking: Focus on complete flows rather than perfect components

Library Usage Philosophy

Use libraries as intended: Minimal wrappers around external libraries
Direct integration: Avoid unnecessary adapter layers
Selective dependency: Add dependencies only when they provide substantial value
Understand what you import: No black-box dependencies

Testing Strategy

Emphasis on integration and end-to-end tests
Manual testability as a design goal
Focus on critical path testing initially
Add unit tests for complex logic and edge cases

Areas to Embrace Complexity

Some areas justify additional complexity:

Security: Never compromise on security fundamentals
Data integrity: Ensure data consistency and reliability
Core user experience: Make the primary user flows smooth and reliable
Error visibility: Make problems obvious and diagnosable

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.

TinkerTasker CLAUDE.md is an instructions file published in the GitHub repository DaveCoDev/TinkerTasker (4 stars, last pushed 1y ago), licensed MIT. It adds 1,000 tokens to every session, about $0.0040 per session on Opus 5.5. 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.
