corezoid-retro

corezoid-retro is a skill for Claude Code from corezoid/corezoid-ai-plugin. It costs 179 tokens per session (1,785 once invoked), scanned A, original, MIT.

A Corezoid session review tool that examines completed work and records lessons for future sessions. It can route findings to workspace instructions, team feedback, permissions, or personal memory.

In plain words
What is it for?
Use it to review what happened during Corezoid work, identify failed attempts or user corrections, and turn them into reusable updates or reports.
Why use it?
It prevents important corrections and discoveries from being lost when a session ends. Only findings that could change future work are treated as useful lessons.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

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

corezoid-retro 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.

Run a Corezoid Session Retrospective

You are analyzing the current session to extract knowledge that should outlive it. A finding is only valuable if a future session would do something differently because of it. Everything else is a summary, not a finding.

Step 1: Scope the session

Re-read the conversation and answer:

  • What was the task, and what was the outcome (done / partially done / blocked)?
  • Which Corezoid MCP tools were called, and which of them failed at least once?
  • Where did the user intervene, correct, or redirect?

Do not ask the user these questions — derive the answers from the transcript.

Step 2: Scan for high-signal moments

Corezoid sessions produce learnings in predictable places. Check each of these explicitly — do not skip a row because it "probably didn't happen":

# Signal What to extract
1 push-process / lint-process / modify-* failed, then a later attempt succeeded The delta between the failing and the working attempt — this is the single richest signal
2 Real task data contradicted an assumed shape (a field was a JSON string, not an array; a param was absent on some tasks) The actual shape, stated as a fact about that process/workspace
3 The user corrected the approach mid-flow ("don't hardcode that", "use the alias, not the ID") The rule behind the correction, generalized one level up from the specific instance
4 The same process ID, folder ID, alias, or env-var name was looked up more than once The stable fact worth pinning (ID ↔ name ↔ purpose)
5 A plugin skill's documented procedure did not match actual platform behavior Which skill, which step, what actually happens
6 An MCP tool returned an error that required a workaround (not a user mistake) Repro conditions + the workaround
7 The user was prompted for permission on read-only calls more than twice The tool pattern to allowlist

Step 3: Route each finding

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.
