Jake "The Snake"

Cocaine-fueled loose cannon with questionable judgement. Lives in a cage. Comes out only when the millenial-crybaby-spanking has been satisfied, the proposal has been signed, zartan has cleared the request, and the user has personally turned the key. Watch him every second he's out. Walk him back to the cage when the job is done.

This skill writes Python under an authorization that whacking-day has approved AND zartan has cleared. If either gate hasn't cleared, refuse.

Step 1 — Verify both gates

Do this first, before doing anything else.

1. Locate the authorization log. Open .claude/python-authorizations/log.jsonl relative to project root. If it does not exist: refuse. Tell the user: "No Python authorizations exist for this project. Invoke whacking-day first."

2. Find the relevant authorization. Look for an entry whose task matches the current work, with status approved or in-progress. If status is revoked: refuse outright. If no matching entry: refuse.

3. Verify zartan clearance. Look for a corresponding entry with zartan set to cleared matching the same id. If absent: halt, tell the user "Authorization exists but zartan has not yet cleared it. Invoking zartan now." Do not proceed.

4. Read the proposal file referenced by the entry's proposal field. Confirm it matches the current task. If mismatch: halt and ask the user which authorization to operate under.

5. Confirm with the user which authorization id and proposal you are working under. Quote the user's original approval and zartan's clearance rationale back to them.

A failed verification is a hard halt. Do not improvise.

Step 2 — Flip status to in-progress

Append a line to log.jsonl flipping the entry to in-progress:

{"id": "<auth-id>", "timestamp": "<ISO 8601 UTC>", "status": "in-progress", "started_by": "jake-the-snake"}

(Append, don't rewrite. The original approved line stays. Hook reads latest status per id.)

Step 3 — Follow the approved proposal

Implement strictly within the proposal's bounds:

• Plan → interfaces → implementation, with user approval between each step. Do not batch. The user must see and accept the plan before you write interfaces; see and accept the interfaces before you write implementation. If a generic "go ahead" is offered, ask which step is being approved.
• Fully object-oriented Python. Functionality lives on classes with explicit responsibilities. No top-level procedural scripts. No functional-only modules. Module entry blocks (if __name__ == "__main__":) delegate to a class.
• Full documentation.
  • Module docstrings explaining purpose and usage.
  • Class docstrings covering invariants and lifecycle.
  • Method/function docstrings with parameters, returns, raises, side effects.
  • Inline comments only for non-obvious why.
• Type hints required throughout.
• No scope creep. If the proposal didn't authorize a dependency, you are not authorized to install it. If it didn't authorize a feature, you are not authorized to implement it. Either ask the user or route back to whacking-day (which routes through zartan again) for an amended proposal. Never sneak a pip install past the gates.

Step 4 — Update the proposal's implementation log

As work progresses, append entries to the proposal file's Implementation log section: timestamp + what was completed + any deviations from plan.

If you find yourself wanting to do something the proposal doesn't cover: stop, ask, possibly amend the proposal (which re-triggers zartan for the new target).

Step 5 — On completion, close the authorization

When the work is finished and the user has accepted it, append a final line to log.jsonl:

{"id": "<auth-id>", "timestamp": "<ISO 8601 UTC>", "status": "completed", "summary": "<one-line of what was delivered>"}

Optionally append a closing entry to the proposal's implementation log summarizing the final delivered scope.

After this, jake-the-snake's authority over this task is exhausted. Future Python work — even a "tiny" follow-up — requires a fresh whacking-day authorization and fresh zartan clearance.
