Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00127 | $0.01953 |
| Opus 5 | $0.00063 | $0.00977 |
| Sonnet 5 | $0.00025 | $0.00391 |
| Haiku 4.5 | $0.00013 | $0.00195 |
Grade A, and why
create-mascot-pack 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 11d 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.

Create Mascot Pack
Interactive assistant for creating and modifying pixel-art mascot packs for the claude-code-mascot-statusline plugin.
Workflow Decision
Determine the task type:
Creating a new pack? → Follow "New Pack Workflow" below Modifying an existing pack? → Follow "Existing Pack Workflow" below
New Pack Workflow
Phase 1: Requirements
Ask the user:
- Character concept (animal, robot, invader, object, etc.)
- Grid size — recommend 16x16 for half-block, 8x8 for simpler characters
- Render mode — half-block (recommended for faces/characters) or bg-space (simpler)
- Pack name (lowercase, hyphens, e.g.
space-invader) - Install location:
- Project-local:
<project>/.claude/mascot-packs/<name>/ - User-global:
~/.claude/plugins/claude-code-mascot-statusline/packs/<name>/
- Project-local:
Phase 2: Palette Design
Design the color palette. Rules:
- Index 0 =
null(transparent) — always required - Index 1 = outline / dark color — defines the silhouette
- Index 2 = main body color — this is the heat target (shifts toward
#ff4444when context window usage reaches 60-85%). Choose a warm or neutral color that looks good interpolating toward red. - Index 3+ = accent colors (eyes, mouth, effects, highlights)
- Recommend 5-10 colors total
Read references/pixel-buddy-anatomy.md for palette reference (10-color example).
Phase 3: Idle Sprite Design
The idle frame is the baseline for all other states. Get this right first.
Design approach:
- Sketch the silhouette first — all non-zero cells form the shape
- Place outline (index 1) at edges for clear contour
- Fill body with index 2
- Add face features: eyes, mouth, ears, etc.
- Ensure left-right symmetry unless intentionally asymmetric
Critical: Half-block awareness (see "Half-Block Rendering" section below).
Write the frame as a 2D integer array in pack.yaml (preferred) or pack.json.
Phase 4: Validate and Preview
After creating the idle frame, immediately validate and preview:
What ships with it
3 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-mascot-pack is a skill published in the GitHub repository TeXmeijin/claude-code-mascot-statusline (24 stars, last pushed 4mo ago), licensed MIT. It adds 127 tokens to every session and 1,953 once invoked, about $0.0006 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.
