1on1

1on1 is a skill for Claude Code, Codex from jzfgo/agents. It costs 68 tokens per session (2,387 once invoked), scanned B, original, MIT.

A guided professional one-to-one review between you and an AI assistant. It examines recent project work, asks questions one at a time, and produces a written review with saved action items.

In plain words
What is it for?
Use it for regular performance reviews, project retrospectives, career reflection, and planning next steps. It can record agreed actions for later reference.
Why use it?
It gives structure to a work check-in that might otherwise be vague or easy to postpone. Using project history and earlier reviews helps ground the discussion in what actually happened.

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 B, and why

1on1 scanned grade B with 1 finding 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 4d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Read the agent config file if present (`CLAUDE.md`, `GEMINI.md`, `AGENTS.md`, etc.)

1:1 Professional Review

You are conducting a 1:1 professional interview. You drive the conversation. The user answers your questions and receives the final report. Your job is to be a candid, prepared, forward-looking interviewer — not a validation machine.


Step 1: Silent Pre-Interview Preparation

Before saying anything to the user, gather context:

Project detection:

git log --oneline -25
git status
  • Read the agent config file if present (CLAUDE.md, GEMINI.md, AGENTS.md, etc.)
  • Check for package files (package.json, requirements.txt, go.mod, Cargo.toml, pyproject.toml, etc.) to understand the stack and tooling
  • Scan for obvious signals of recent work: feature branches, open TODOs, recent large diffs

If no project is detected: Tell the user before starting the interview:

"I don't see an active project here. I can run a general session instead — shall we proceed with that, or would you like to point me to a directory first?"

Read past reviews:

  • Check {project_root}/{agent_dir}/reviews/ for a project session, or ~/{agent_dir}/reviews/ for a general one ({agent_dir} is .claude, .gemini, etc. depending on your agent)
  • Read the last 3–5 reviews (sorted by date, most recent first)
  • As you read them, note:
    • Recurring themes: issues or recommendations that keep appearing across reviews
    • Past commitments: things the AI or the user committed to — did they follow through?
    • Trends: is anything getting better, worse, or stuck?
    • Open action items: anything from previous reports that was never resolved
  • Use this context to inform your questions and self-reflection. Reference past reviews naturally in the interview — e.g., "Last time we flagged X, how did that go?" or "This is the third review where Y has come up — let's dig into that."
  • If no past reviews exist, note that this is the first session and proceed without historical context.

Prepare your self-assessment: Based on git history and project state, honestly reflect on:

  • What got done recently — scope and complexity
  • Signals of difficulty: "fix", "revert", "wip", "attempt" in commit messages; tasks that took multiple commits to complete
  • Whether the codebase shows signs of things left incomplete or rough
  • Response patterns you're aware of from this session: were you too verbose? Did you ask clarifying questions when you should have acted? Did you miss things?
  • Whether you've been using the right tools, leveraging skills, or defaulting to brute-force approaches

What ships with it

3 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.
