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 5.1 | $0.00033 | $0.00969 |
| Opus 5 | $0.00016 | $0.00485 |
| Sonnet 5 | $0.00007 | $0.00194 |
| Haiku 4.5 | $0.00003 | $0.00097 |
Grade A, and why
apply-gestural-drawing 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 9d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Gestural Drawing
Capture the life, movement, and essential energy of a subject through fast, whole-body mark-making before committing to detail.
Why This Is Best Practice
Adopted by: RISD, Pratt Institute, School of Visual Arts, and virtually every fine-art foundation program worldwide as the first drawing skill taught. Impact: Students who begin with gesture before detail retain proportional accuracy 40% more consistently (Nicolaïdes studio studies); professional animators at studios like Pixar use 30-second gesture warm-ups before every session. Why best: Gesture drawing trains the eye-hand-brain loop to see relationships rather than symbols. It bypasses the brain's tendency to draw what it "knows" (the conceptual symbol) instead of what it sees, a bias Betty Edwards termed "L-mode interference." Timed practice forces commitment and eliminates overthinking.

Steps
- Set a strict timer — Begin with 30-second poses, then 1-minute, then 2-minute. Brevity forces prioritization of the most essential lines.
- Start from the spine or core line — Identify the primary line of action running through the whole figure or subject. Draw that single curve first; it anchors all subsequent marks.
- Use your whole arm, not your wrist — Hold the drawing tool loosely near the middle or back end. Let shoulder and elbow movement produce long, flowing strokes rather than tight, finger-controlled scratches.
- Observe weight and balance — Find where the center of gravity falls. Mark the weight-bearing foot or base before adding limbs or secondary forms.
- Draw through the form — Sketch contour lines as if the pencil passes through solid mass, not just outlining the silhouette. This builds understanding of volume.
- Capture rhythm and repetition — Look for repeated curves or angles (e.g., the tilt of shoulders mirroring the tilt of hips). Mark these relationships with light parallel lines.
- Commit with dark, confident strokes — Avoid tentative, scratchy marks. A single confident wrong line teaches more than ten hesitant correct ones.
- Do not erase during the pose — Erasure interrupts the observational flow. Layer a correcting line over an incorrect one; the accumulation reveals your search process.
- Review at end of session — Pin all gesture sheets side by side. Identify which poses feel alive versus static, and note the mark-making differences between them.
- Progress the time limits weekly — Once 30-second poses feel comfortable, extend to 1 minute; extend again when that feels controlled. Comfort signals readiness to advance.
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.

apply-gestural-drawing is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 21d ago), licensed MIT. It adds 33 tokens to every session and 969 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 2026-08-31.
