superfixer-debug

superfixer-debug is a skill for Claude Code, Codex from peteromallet/Arnold. It costs 155 tokens per session (10,397 once invoked), scanned A, original, Apache-2.0.

An evidence-first recovery process for a stuck Megaplan task or another automated pipeline. It gathers context, creates an ordered fix plan, and carries out the approved implementation.

In plain words
What is it for?
It helps investigate failures, collect evidence, plan corrective work, fix the underlying cause, and resume an interrupted pipeline.
Why use it?
It helps move stalled automation forward while separating the durable root fix from temporary steps that only unblock progress.

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

superfixer-debug 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 1mo 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.

The opening of the file, as written. The whole thing — 814 lines — stays where its author put it; the contents beside it link to each section on GitHub.

superfixer-debug

This skill replaces the former “stack of fixers” playbook. It is a decision and custody protocol, not a license to hand-advance a run. Its invariant is:

Evidence first → Sol scoping judgement → bounded DeepSeek V4 Flash evidence → Sol adjudication → canonical movement route → authoritative proof.

The fixer keeps custody until the accepted work is moving. A quarantine receipt is an evidence checkpoint, never a successful terminal outcome. When the preserved occurrence cannot safely resume, Sol must choose either an authority-approved migrated child or a canonical control-plane repair that makes the missing identity or authority durable, then the ordinary fixer must execute that route and prove cursor/milestone advancement. “No safe retry” is not a durable answer when the blocking seam is repairable. No route may fabricate history, bypass authority, or weaken a validator; a genuinely external approval remains an explicit gate with an active next-owner route.

No-op and coordination guards (run these first)

Before doing anything else:

  • NO-OP: enumerate blocked/failed chains. If none are blocked or failed, report "No blocked/failed chains found; nothing to fix" and end. Do not invent work, fabricate a failure, or touch healthy/running chains.
  • COORDINATION: check whether another fixer/repair is already active for the target chain. Use the RELIABLE signals (cloud status may not be available if the initiative has no cloud.yaml): (a) a FRESH managed subagent dir for this session under .megaplan/plans/resident-subagents/subagent-* (created in the last hours), (b) a held repair lease via inspect_repair_lock, or (c) a running subagent_worker process for that session. If any signal is active, report "Another fixer is already active for this chain; standing down" and end — never launch a competing fixer.

Epic-babysitting operational loop

This skill also covers "epic-babysitting": keeping the target chain actually moving, not just fixing one layer. Repeat this loop until the canonical milestone advances (index > 0):

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.
