Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00037 | $0.05886 |
| Opus 5 | $0.00018 | $0.02943 |
| Sonnet 5 | $0.00007 | $0.01177 |
| Haiku 4.5 | $0.00004 | $0.00589 |
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.

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.changelogabove — 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:
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.
