autonomous-dev

autonomous-dev is a skill for Claude Code, Codex from neverinfamous/memory-journal-mcp. It costs 58 tokens per session (841 once invoked), scanned B, original, MIT.

A controlled workflow for having an AI agent fix software issues while checking project goals, security, testing, and collaboration practices.

In plain words
What is it for?
Use it for known bugs, security fixes, multi-step features, architectural work, and deployment-related development when the repository has a PROJECT.md file defining its goals and constraints.
Why use it?
It prevents work from drifting outside the project's agreed scope and adds checks against unsafe code, exposed secrets, and unreviewed 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 B, and why

autonomous-dev scanned grade B with 1 finding 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 3d 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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **Command Gates**: Do not execute destructive commands (`rm -rf`, `git reset --hard`) without explicit Human-in-the-Loop approval.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Autonomous Development Workflow

This skill provides a deterministic software engineering harness, designed to wrap AI code generation with strict alignment gates, adversarial evaluations, CI/CD pipeline principles, and collaborative Git practices. Load this skill when designing or orchestrating multi-step architectural features, automating deployment workflows, or writing code inside a structured environment.

1. Project Alignment Gate (PROJECT.md)

Before beginning implementation, you MUST cross-reference the proposed feature against PROJECT.md at the repository root. If PROJECT.md is missing, ask the user to clarify the project goals or constraints before proceeding.

  • In-Scope: Confirm the feature directly serves a goal in PROJECT.md. Proceed.
  • Out-of-Scope: Hard block. Halt work immediately and inform the user.
  • Constraints: Abide strictly by the constraints (language, architecture, dependencies) defined in the project file.

2. Security Safety Nets

  • Execution Sandboxing: Never run unknown or unverified shell scripts directly. Execute isolated tasks within the tmp/ scratch directory.
  • Secret Protection: Check for exposed credentials or PII in diffs before committing. Never commit .env.
  • Command Gates: Do not execute destructive commands (rm -rf, git reset --hard) without explicit Human-in-the-Loop approval.

3. Generator / Evaluator Pipeline

Features cannot simply be written and committed. They must navigate a rigid pipeline based on the adversarial evaluation pattern:

  1. Research: Analyze local scope and external dependencies via parallel search strategies.
  2. Planning: Formulate architecture and acceptance criteria (generator).
  3. Acceptance Tests FIRST: Tests must be written before main implementation (TDD).
  4. Implementation: Produce code.
    • HARD GATE: 0 test failures. You cannot proceed if tests fail. No stubs/placeholders allowed.
  5. Adversarial Review: Self-evaluate the code as a skeptical reviewer (evaluator). Actively search for edge cases, security vulnerabilities, efficiency loss, and anti-patterns.
  6. Documentation: Ensure docs stay tightly in sync with the codebase after the feature clears CI.

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.

autonomous-dev is a skill published in the GitHub repository neverinfamous/memory-journal-mcp (20 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 841 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
