claude-code-decompiled (research reports)

A documentation-only collection of 20 independent research reports on Claude Code v2.1.88 covering architecture, agent behavior, permission design, prompt assembly, MCP integration, and context management. Deliberately ships analysis rather than extracted code.

Key takeaways

• 01

  Report set spans permissions, prompt assembly, MCP, and context management

• 02

  Documentation-only approach is the cleanest for attribution

• 03

  Strong specifics on permission tiers around dangerous tools

Flows built on this research

MCP & Tooling

Design Tool Schemas for Agents

Write tool schemas that constrain model behavior: tight types, enums over strings, and parameters that make misuse hard.

4 steps · 60-90 minutes

Harness Engineering

Hook a Permission Layer onto Dangerous Tools

Intercept dangerous tool calls with a hook layer: pattern rules, approval gates, and blocks that the model cannot talk its way past.

4 steps · 60-90 minutes

Agent Architecture

Sub-Agent Delegation with Context Isolation

Delegate bounded work to sub-agents that run in fresh context and return only distilled results - the pattern behind scalable long tasks.

4 steps · 90-150 minutes

MCP & Tooling

Deferred Tool Loading

Stop paying context for tools the task never needs: load a core set eagerly and expand the toolset on demand.

4 steps · 90-120 minutes

Harness Engineering

Rate and Blast-Radius Limits for Destructive Tools

Cap how much damage any window of agent activity can do: rate limits, change budgets, checkpoints, and undo.
