second-brain-changed-my-mind

Trace where the user's recorded position on something has shifted: superseded claims, contradictions between sources of different dates, and what evidence moved them. Use this skill when the user asks what they have changed their mind about, how their thinking on a topic developed, what they used to believe, or wants a quarterly look back at their own positions. Do NOT use for finding contradictions between sources with no time dimension, or for a current-state answer.

Trace changed positions

This is the query a vault can answer that nothing else can, and the reason the supersession rules exist. It only works because contradictions are recorded rather than overwritten.

Core rule

Report the change with both positions, both dates and the evidence between them. A conclusion without its history is just the current claim.

Workflow

  1. Find superseded claims across concept pages, and contradictions where the sources differ in date.
  2. Reconstruct the sequence: what the page said, when, based on what; what changed it, when.
  3. Distinguish real revision from correction. A factual error being fixed is not a change of mind. A conclusion being revised on better evidence is.
  4. Flag unresolved ones. Contradictions still sitting open are the most actionable output here.
  5. Say how firm the current position is, based on what moved it.

Output format

## <topic>
Was: <claim> (<source>, <date>)
Now: <claim> (<source>, <date>)
What moved it: <evidence>
Firmness: <what would move it again>

## Still unresolved
<contradictions with no current position>

Calibration

If nothing has changed in the period, say so in one line. Manufacturing an apparent revision from two pages that never disagreed is worse than an empty result.

Never present the more recent source as correct by virtue of being recent.

概要と使いどころ

Audit an agent's context layout against the four places: system prompt, tools, history, tail. Use when the user asks to audit, review or fix their agent's context, prompt caching, token spend per turn, or CLAUDE.md / AGENTS.md layout. Read-only: reports findings and a fix list, changes nothing. Do NOT use for writing evals (evals-bootstrap) or for loop design (goal-test).

Scaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner. Use when the user wants evals, regression tests for an agent, a golden set, or asks how to know a prompt/model change did not break things. Do NOT use for a single task's done-check (goal-test) or for auditing context (context-audit).

Find the decisions in a pipeline that do not need the expensive model and propose the gate for each: a rule, a classic classifier, or a small model, with fail-closed routing. Use when the user asks to cut model costs or latency, says the big model handles everything, or wants a triage / routing / filter layer in front of an agent. Analysis plus an optional baseline scaffold. Do NOT use for auditing context layout (context-audit) or for building eval suites (evals-bootstrap).

goal-test

無料

Turn a vague task into a testable definition of done and generate an executable goal-test script for it, optionally with a bounded retry loop around a headless agent. Use when the user wants to run an agent in a loop, asks how to know when an agent task is finished, or says a goal like "improve X" needs to become checkable. Do NOT use for building eval suites over many cases — that is evals-bootstrap.

Audit an agent's harness against the four rings: containment, guides, sensors, permissions. Use when the user asks whether their agent setup is safe, wants a review of sandboxing / permissions / hooks / AGENTS.md guardrails, or asks what a bad session could break. Read-only: reports the blast radius and a hardening list, changes nothing. Do NOT use for context layout (context-audit) or cost routing (gate-check).

Import a large archive into the vault in controlled batches: triage what is worth ingesting, process oldest first, checkpoint after every batch, and keep cost visible. Use this skill whenever the user wants to import years of bookmarks, an export from another notes app, a downloads folder, a chat history dump, or says "backfill", "bulk import", "process my archive". Do NOT use for ingesting one or a few new sources, which is second-brain-ingest.
