kenjaku: Skill for Claude Code

.claude/skills/sync-sources/SKILL.md

sync-sources is a skill for Claude Code from tpierrain/kenjaku. It costs 83 tokens per session (10,927 once invoked), scanned A, original, Apache-2.0.

An internal read-only workflow for collecting the latest changes from connected sources such as Slack, Google Drive, meeting transcripts, Calendar, and email. It sends parallel readers out and combines their local Markdown summaries.

In plain words
What is it for?
Use it as the background source-synchronisation phase of a question or morning briefing when the relevant connectors are configured.
Why use it?
It brings external context into the local knowledge base without sending messages, emails, or reactions.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions subagents.

This is tpierrain/kenjaku's own configuration. It tells Claude Code how to work on kenjaku itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything kenjaku configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is real names of the connectors you've wired up (see [SETUP §6](../../../SETUP.md)). Without a wired.

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

sync-sources 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 1mo 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 — 725 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sync sources — Fan-out/fan-in architecture (internal reference)

This is not a user command. This file documents the sub-agent architecture of Phase 2 of the main flow (sync sources in background — see CLAUDE.md). You never trigger the pull by hand: it's the question that triggers it. Note: /sync is a separate command that synchronizes the git repo between machines.

🔧 Adapt to your connectors. The examples below reference MCP tools generically (mcp__<slack>__…, mcp__<drive>__…, mcp__<calendar>__…). Replace them with the real names of the connectors you've wired up (see SETUP §6). Without a wired connector, this skill does nothing — the RAG engine answers on its own from the vault.

Absolute constraint

READ-ONLY. Never send a message, an email, or a reaction. Never post in a channel. Produce only local markdown files in the vault.

Sub-agent tooling — NEVER a shell to process text

The sub-agents are LLMs: they read and summarize by reasoning, not via the shell. Forbidden to use python3 -c, python, node -e, awk, sed, jq, grep, cat, head, tail — or any Bash command — to parse, load, split, slice or summarize content. Why this is non-negotiable (especially on Claude Desktop, Code tab):

  • each ad-hoc command is unique → it re-triggers an authorization prompt on every call (endless prompts, impossible to pre-authorize);
  • some (multi-line, # inside an argument, redirections) are refused for security and don't even offer "Always allow" — the user cannot accept them.

Instead:

  • Read content → the Read tool (a vault file; or a large tool result that Claude offloaded to …/tool-results/…: read it with Read, not with python3 -c "open(...)").
  • Write the raw source / the briefing → the Write / Edit tools.
  • Split ("up to the Details section", "the first 4000 characters"…) → in your head, not in Python.

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.
