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 | $0.00041 | $0.00620 |
| Opus 5 | $0.00020 | $0.00310 |
| Sonnet 5 | $0.00008 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
create-skill 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 5d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
create-skill
Creates and validates skills for the PAL Second Brain vault. Skills live in .claude/skills/[name]/ and follow the canonical flat structure defined in SKILL-LOGIC.md.
Authoritative Source
Before creating or validating any skill, read:
.claude/core/system/SKILL-LOGIC.md— naming conventions, structure rules, SKILL.md format
Skill Structure (Quick Reference)
.claude/skills/[skill-name]/
├── SKILL.md # Required — entry point and routing table
└── workflows/ # One file per workflow
└── workflow_name.md
Naming:
- Directory:
lower-kebab-case SKILL.md: uppercase- Workflow files:
kebab-case.md - YAML
name:field:lower-kebab-case(matches directory)
No tools/, context/, docs/, or resources/ subdirectories. Context files live at skill root if needed.
Workflow Routing
| Workflow | Trigger | File |
|---|---|---|
create-skill |
"create skill", "new skill", "build skill" | workflows/create-skill.md |
validate-skill |
"validate skill", "check skill", "audit skill" | workflows/validate-skill.md |
update-skill |
"update skill", "add workflow", "modify skill" | workflows/update-skill.md |
canonicalize-skill |
"canonicalize skill", "fix skill structure", "clean up skill" | workflows/canonicalize-skill.md |
Examples
Example 1: Create a new skill
User: "Create a skill for managing cooking recipes"
→ Invokes create-skill workflow
→ Reads SKILL-LOGIC.md
→ Creates .claude/skills/recipe-manager/ with SKILL.md + workflows/
→ Generates USE WHEN triggers based on intent
→ Registers in reference/SYSTEM-INDEX.md
Example 2: Validate an existing skill
User: "Validate the daily-rituals skill"
→ Invokes validate-skill workflow
→ Checks naming, frontmatter, workflow routing table, Examples section
→ Checks registration in reference/SYSTEM-INDEX.md
→ Reports compliance with issues and fixes
Example 3: Fix a skill with old structure
User: "Canonicalize the qmd skill"
→ Invokes canonicalize-skill workflow
→ Renames any wrongly-named files
→ Ensures SKILL.md has correct format
→ Verifies workflow routing table is accurate
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

create-skill is a skill published in the GitHub repository superuser-pal/awesome-second-brain (14 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 620 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
