kenjaku: Skill for Claude Code

.claude/skills/improve/SKILL.md

improve is a skill for Claude Code from tpierrain/kenjaku. It costs 31 tokens per session (460 once invoked), scanned A, original, Apache-2.0.

A continuous-improvement workflow for a coding or automation harness: the surrounding files and processes that help agents work.

In plain words
What is it for?
Use it to inspect the improvement backlog, identify problems from a session, propose priorities, and implement and test selected changes.
Why use it?
It turns repeated workarounds, failed skills, and hard-to-find information into tracked improvement tasks instead of letting the same friction recur.

Skill for Claude Code

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

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 →

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

improve 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 2mo 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.

What it actually says

/improve — Continuous improvement of the harness

Routing

  • No argument → Session mode (A).
  • ajouter <description> (or add) → Quick-add mode (B).

MODE A — Improvement session

A1 — Read the backlog and observe

  1. Read vault/backlog/harnais.md (backlog of pending improvements).
  2. Read the most recently modified files in .claude/skills/ to understand the state of the harness.
  3. If the conversation has 10+ exchanges, detect frictions:
    • Repeated workarounds (same action 2+ times)
    • Questions the vault couldn't answer
    • Failed skills or unsatisfactory results
    • Too many rounds to find a piece of information Add the observations to the backlog with the [observation] tag.

A2 — Propose the priority improvements

Present the 3 most impactful improvements, prioritized by impact/effort ratio, recurrence, leverage. For each: title + tag, impact (1 sentence), effort (quick win < 30 min / project), proposal (2-3 lines). End with: "Which one do we tackle?"

A3 — Implement

  1. Make the changes (skills, CLAUDE.md, vault structure…).
  2. Test if possible (dry run, syntax check).
  3. Mark the item [x] + date in vault/backlog/harnais.md.
  4. Let the hook commit.

MODE B — Quick add

Add the idea to vault/backlog/harnais.md: categorize (quick win / project / idea), [explicite] tag + today's date, confirm in one line. Do not implement.


Passive observation (outside the skill)

Rule in CLAUDE.md (section 5). Applies automatically to every session of 10+ exchanges, not only when /improve is invoked.

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.
