kenjaku: Skill for Claude Code

.claude/skills/prepare-1-1/SKILL.md

prepare-1-1 is a skill for Claude Code from tpierrain/kenjaku. It costs 120 tokens per session (2,128 once invoked), scanned A, original, Apache-2.0.

A read-only briefing workflow for preparing a one-to-one meeting with your manager or with someone you manage.

In plain words
What is it for?
Use it with a person’s name or alias to review their profile, previous one-to-ones, recent notes, commitments, operational topics, and key performance indicators, then produce a local briefing.
Why use it?
It gathers relevant history and recent changes so you can spend the meeting on meaningful topics rather than searching through notes.

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

prepare-1-1 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.

How it starts

The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/prepare-1-1 — Prepare a 1-1 (meta version)

Produces a briefing scannable in 2 minutes before your next 1-1. This is a meta skill: it lays out a structure that gives you ideas; you then refine it to your own focus areas, your KPIs and the way you run your 1-1s (edit this file, or ask /improve to help you).

Parameter

A name or alias of a person in $ARGUMENTS (e.g. /prepare-1-1 jane). Used to find vault/people/<firstname-lastname>.md (kebab-case, no accents) and the cache vault/backlog/<name>.md. If no profile matches, suggest the closest profiles from vault/people/ and stop.

Absolute constraint

READ-ONLY. Never send a message, email or reaction, never post anywhere. Produce only a local markdown file in the vault.

Step 0 — Direction of the 1-1 (determines the output structure)

Two cases, depending on your relationship with the person (infer it from their role in vault/people/<name>.md; when in doubt, ask):

  • A · 1-1 with YOUR manager (you are the managee) → "what I want to raise" structure.
  • B · 1-1 with someone YOU manage (a report, or a peer you coach) → "follow-up + operational + KPI" structure.

Step 1 — Collection (fan-out, READ-ONLY)

In parallel (sync-sources architecture, ~500-token summaries):

  • Backlog cache: vault/backlog/<name>.md — open / recurring actions (a point raised 2+ times without closure is a priority).
  • Last 1-1: the note in vault/meetings/ (or via your Calendar connector) — transcript read by an isolated sub-agent (never raw transcript in the main context). Also note the next 1-1 (date of the output file; otherwise today's date).
  • Delta since the last 1-1: messaging, email, shared meetings — depending on your connectors.

Claim discipline

The full rules live in one place — sync-sources § Claim discipline — and this skill obeys them rather than restating its own. Two paraphrases are two disciplines; the control belongs where the facts are produced, and this skill consumes that fan-out.

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.
