secondme-skill

secondme-skill is a skill for Claude Code, Codex from acnlabs/OpenPersona. It costs 40 tokens per session (936 once invoked), scanned A, original, MIT.

A workflow for building a private AI persona from your own data. It covers identity extraction, a personal knowledge base, local model training, and decisions about what information may be shared.

In plain words
What is it for?
Use it to extract identity information, build and update a personal knowledge base, train a local model, and manage sharing rules.
Why use it?
It organizes the work of creating an AI that reflects you while keeping the data and model under your control. It also separates the source information, generated files, and pipeline state.

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

secondme-skill 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 5d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (generated/persona-secondme-skill/scripts/memory.js, generated/persona-secondme-skill/scripts/state-sync.js, publish.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

secondme-skill

secondme-skill is a complete pipeline for building your AI Second Me — distill your identity from owned data, grow a private knowledge base, train a local model that speaks like you, and govern what gets shared. Local-first, privacy-first, fully yours.

This is an orchestration skill package. It does not replace lower-level capabilities.

Source of truth

  • Persona source declaration: persona.json
  • Pipeline runtime state: state/pipeline-state.json
  • Product and governance spec: references/product-report.md
  • Generated runtime pack: generated/persona-secondme-skill/
  • Regeneration script: scripts/regenerate-pack.sh

Dependency chain

  • Foundation: openpersona -> persona pack creation and lifecycle baseline
  • Orchestration: secondme-skill -> workflow gates, state, and report contracts
  • Capability chain:
    1. anyone-skill -> identity extraction and evidence grading
    2. persona-knowledge -> data ingestion, deduplication, wiki/KG, versioned export
    3. persona-model-trainer -> local training, evaluation, export, integration

Required execution policy

  • Use non-interactive generation and scripts where possible.
  • Keep local-first and least-privilege defaults.
  • Keep stage outputs auditable with version/hash references.
  • Treat persona-secondme-skill/ as generated output (read-only baseline).
  • When persona.json changes, regenerate the runtime pack before release.
  • Before publishing outside this repository, run scripts/publish-check.sh.
  • Preferred release check path: scripts/run-gates.sh (regenerate + sync + model gate + publish gate).

Stage contract

init

  • Validate toolchain and directories.
  • Initialize or load state/pipeline-state.json.

ingest

  • Ingest user-owned data with PII scanning.
  • Require explicit source authorization from user.

distill

  • Build structured persona extraction artifacts.
  • Ensure minimum persona input for OpenPersona is complete.

train

  • Route by hardware tier:
    • Apple Silicon: mlx
    • NVIDIA: unsloth
    • No local GPU: colab

What ships with it

51 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
