adjust-playbook

A procedure for changing an existing playbook, which is a reusable set of instructions for completing a task. It covers finding the playbook, then updating, fixing, extending, or refining it while preserving its main behavior.

In plain words
What is it for?
Use it when a user asks to update a playbook, add a step, fix a problem, change its schedule, or refine it after a run.
Why use it?
It provides a repeatable way to improve existing playbooks without accidentally replacing their structure or purpose.

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

adjust-playbook 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 619 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Adjust Playbook

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of metadata.changelog above — e.g. adjust-playbook vX.Y — recent: <summary>. Then proceed.

Modify existing playbooks while preserving their core structure and functionality.

When to Use

  • User says "update the X playbook"
  • User says "add Y to the playbook"
  • User says "fix the Z step"
  • User says "change the schedule"
  • After running a playbook and finding issues

Workflow

Step 1: Locate the Playbook

If $0 (playbook name) provided:

# Check project skills
ls .claude/skills/$0/SKILL.md 2>/dev/null

# Check personal skills
ls ~/.claude/skills/$0/SKILL.md 2>/dev/null

# Check plugin skills (when inside a plugin/marketplace repo)
ls plugins/*/skills/$0/SKILL.md 2>/dev/null

If not provided or not found, list available playbooks:

echo "=== Project Playbooks ==="
for d in .claude/skills/*/; do
  [ -f "$d/SKILL.md" ] && grep -l "automation:" "$d/SKILL.md" 2>/dev/null && basename "$d"
done

echo "=== Personal Playbooks ==="
for d in ~/.claude/skills/*/; do
  [ -f "$d/SKILL.md" ] && grep -l "automation:" "$d/SKILL.md" 2>/dev/null && basename "$d"
done

echo "=== Plugin Playbooks (when inside a plugin/marketplace repo) ==="
for d in plugins/*/skills/*/; do
  [ -f "$d/SKILL.md" ] && grep -l "automation:" "$d/SKILL.md" 2>/dev/null && echo "$d"
done

Ask user to select if multiple options.

Step 2: Read Current Playbook

Read the full SKILL.md:

cat [path]/SKILL.md

Parse and display structure:

## Current Playbook: [name]

**Automation**: [level]
**Schedule**: [cron or none]
**Location**: [path]

**State Dependencies**:
[table or "none defined"]

**Process Steps**: [count]
1. [step name]
2. [step name]
...

**Approval Gates**: [count]
**Checklist Items**: [count]

Step 3: Determine What to Change

From $ARGUMENTS or conversation context, identify:

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.
