Claude Code

#entity

Summary

Anthropic's agentic coding CLI/harness, cited across most of the corpus as the reference harness and used by every practitioner in it except thorsten-ball (who runs amp). Used interactively and in fire-and-forget / scheduled modes.

Current Understanding

Claude Code recurs as the concrete example of the "universal agent" pattern: a short system prompt, ~10–40 file/shell/search tools, a ReAct runtime loop, standardized key files (CLAUDE.md, skills/), and native scheduling. It supports both skills-as-memory and MCP — and notably converts MCP servers into skills so their tools don't all hit context at once, erasing most MCP downsides (evolution-of-agent-tooling).

Practitioner limits (from the 2026-07-21-larysa-interview) — the corpus's most critical first-hand read:

Built-in memory is judged an anti-feature by Eugene ("it'd be better if it didn't [exist]"); use skills instead. See skills-as-memory.
Connectors overpromise. The agent begins work before establishing whether an integration is implemented or available for the user's account tier — see integration-dead-ends. Slack has first-class Anthropic support (paid seat required); Teams is treated as a dead end; Figma editing needs a paid account.
Model selection matters within the family. Eugene runs 4.7 in production and avoids 4.8 as "too proactive." Code output is considered production-safe from ~4.6 onward, excluding authorization and payments (code-as-throwaway).
Testing surface: browser/web testing works; a mobile emulator got badly stuck.

Contradictions / Uncertainty

Sources treat Claude Code as the harness baseline but disagree on governance: personal/custom (Eugene) vs company-managed at scale (Sebastian — see enterprise-ai-reality).
Model-version judgements (4.7 good / 4.8 too proactive) are one practitioner's production preference at one point in time, not a benchmark, and will date quickly. Status: tentative.

Next Questions

What does a compliant, company-managed Claude Code deployment look like for regulated teams?
Is there a supported way to make the agent check integration entitlements before starting a task?
