apply-gestural-drawing

apply-gestural-drawing is a skill for Claude Code from jeffreytse/grimoire-core. It costs 33 tokens per session (969 once invoked), scanned A, original, MIT.

A drawing practice for quickly capturing a subject’s movement, posture, and overall energy before adding details.

In plain words
What is it for?
Use it for timed figure or observational drawing warm-ups, starting with short poses and gradually allowing more time for structure and detail.
Why use it?
It trains observation and proportion while reducing the tendency to overthink or draw a simplified symbol instead of what is actually seen.

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

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.

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

  1. Set a strict timer — Begin with 30-second poses, then 1-minute, then 2-minute. Brevity forces prioritization of the most essential lines.
  2. 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.
  3. 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.
  4. Observe weight and balance — Find where the center of gravity falls. Mark the weight-bearing foot or base before adding limbs or secondary forms.
  5. 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.
  6. 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.
  7. Commit with dark, confident strokes — Avoid tentative, scratchy marks. A single confident wrong line teaches more than ten hesitant correct ones.
  8. 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.
  9. 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.
  10. 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.
