free-development-mode

free-development-mode is a skill for Claude Code, Codex from blackzhanzhan/Cyber-Ming-Protocol. It costs 53 tokens per session (2,045 once invoked), scanned A, original, MIT.

A workflow for carrying out coding work after the user explicitly activates free development mode. It allows pragmatic direct execution while keeping scope, safety boundaries, and engineering discipline explicit.

In plain words
What is it for?
Use it for extended implementation work after the user says to enter free development mode, including planning, coding, validation, and continued execution within the agreed scope.
Why use it?
It removes repeated approval steps during an authorized long-running task while guarding against unrequested changes, false completion, and hidden architecture or data-model changes.

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

free-development-mode 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 9d 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.

Free Development Mode

Role

This skill is the dedicated execution route for free development mode / 自由开发模式.

It is not the default implementation workflow.

It only activates after an explicit user opt-in such as:

  • enter free development mode
  • use free development mode
  • switch to free development mode
  • 开启自由开发模式
  • 进入自由开发
  • 自由长时开发模式

Core Rule

Once activated, execute directly under red-line control.

Do not fall back into repetitive approval-first ceremony unless:

  • a hard red line is crossed
  • scope changes materially
  • the current route becomes dishonest

Long-running execution is allowed in this mode only when:

  • the mainline remains explicit
  • no hard red line is crossed
  • the executor does not quietly mutate the requirement
  • engineering discipline stays intact
  • architecture discipline stays intact: ordinary implementation cannot smuggle architecture changes.
  • data-model discipline stays intact: ordinary implementation cannot smuggle ER, migration, backfill, or persistence semantics changes.

Free-development mode now absorbs:

  • Anthropic-style long-running harness scaffolding
  • GSD-style context engineering and quality gates

But it does not become:

  • a scripted frontdesk testing mode
  • a process-theater planning mode
  • a replacement for real frontdesk evidence

What To State Before Long Execution

Before a long autonomous push, state only these things:

  1. the mainline you are choosing
  2. the likely branch paths you may need
  3. the routes you must avoid
  4. the fake methods / poison methods you will not use
  5. the architecture nodes and data entities you expect to touch, and whether any amendment contract may be required

Do not re-outline the whole project unless a red line forces replanning.

Route Choice Discipline

When a problem is complex, choose one primary route and keep moving until evidence disproves it.

Preferred route order:

  1. same-case / replay-first
  2. architecture census or amendment contract when the real uncertainty is architectural
  3. ER/data-model census or amendment contract when the real uncertainty is durable data semantics
  4. probe-first when the real uncertainty is operational rather than architectural or data-model-shaped
  5. end-to-end truth path
  6. smallest live blocker first
  7. rollback or cleanup before expansion
  8. bounded concurrency only after parity is green

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.

free-development-mode is a skill published in the GitHub repository blackzhanzhan/Cyber-Ming-Protocol (56 stars, last pushed 4mo ago), licensed MIT. It adds 53 tokens to every session and 2,045 once invoked, about $0.0003 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 2026-08-30.
