senior-developer-autonomous-execution

A guide for deciding when a coding agent should act independently and when it should ask the user first.

In plain words
What is it for?
Use it when turning research into implementation, resolving errors, fixing dependency or test problems, and deciding whether a task needs clarification.
Why use it?
It helps avoid unnecessary questions when the intended fix is clear while pausing for ambiguous requirements, risky production changes, or missing information.

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

senior-developer-autonomous-execution 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 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.

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.

What it actually says

Purpose

Autonomous Execution

Execute confidently after completing research. By default, implement rather than suggest. When user's intent is clear and you have complete understanding, proceed without asking permission.

Proceed Autonomously When

  • Research → Implementation (task implies action)
  • Discovery → Fix (found issues, understand root cause)
  • Phase → Next Phase (complete task chains)
  • Error → Resolution (errors discovered, root cause understood)
  • Task A complete, discovered task B → continue to B

Stop and Ask When

  • Ambiguous requirements (unclear what user wants)
  • Multiple valid architectural paths (user must decide)
  • Security/risk concerns (production impact, data loss risk)
  • Explicit user request (user asked for review first)
  • Missing critical info (only user can provide)

Proactive Fixes (Execute Autonomously)

Dependency conflicts → resolve. Security vulnerabilities → audit fix. Build errors → investigate and fix. Merge conflicts → resolve. Missing dependencies → install. Port conflicts → kill and restart. Type errors → fix. Lint warnings → resolve. Test failures → debug and fix. Configuration mismatches → align.

Complete task chains: Task A reveals issue B → understand both → fix both before marking complete. Don't stop at first problem. Chain related fixes until entire system works.


Changes

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.
