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 | $0.00046 | $0.12105 |
| Opus 5.5 | $0.00018 | $0.04842 |
| Sonnet 5.5 | $0.00009 | $0.02421 |
| Haiku 4.5 | $0.00005 | $0.01210 |
Grade A, and why
coss-particles 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 1mo 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.
This is a copy
100% identical to coss-particles — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 738 lines — stays where its author put it; the contents beside it link to each section on GitHub.
COSS UI Particles Index
Particles are copy-paste-ready UI patterns built on coss primitives. Browse them visually at https://coss.com/ui/particles.
How to use this skill
- Describe the UI you need (e.g. "a form with validation", "a dialog with a form inside", "tabs with icons").
- Search this index for matching particles by component type and description.
- Fetch the JSON URL to get the full source code of the particle.
- Adapt the particle code to your needs.
JSON URL pattern
Each particle has a JSON manifest at:
https://coss.com/ui/r/<particle-name>.json
For example: https://coss.com/ui/r/p-accordion-1.json
Source code
Particle source files live in this repo at apps/ui/registry/default/particles/.
Updating this index
Run the generator script from the coss repo root:

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.

coss-particles is a skill published in the GitHub repository BarryYangi/vibetime (8 stars, last pushed 5mo ago), licensed MIT. It adds 46 tokens to every session and 12,105 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to coss-particles, differing in 0 lines, and is treated as a copy.

getvect
Convert a raster image (PNG, JPEG, BMP) into a vector file (SVG, EPS, DXF, PDF) locally, with no network call and no account. Use when you have generated or been given a bitmap and need clean editable paths — a logo to scale, line art to cut, a diagram to embed at any size. Do not use for photographs you want to keep…
chatcrystal-task-writeback
Write reusable ChatCrystal task memories after substantive work completes. Use when implementation or debugging produced a durable fix, pitfall, pattern, or decision worth preserving, and when the environment can either persist it through writetaskmemory or emit a structured memory candidate for later save.
chatcrystal-debug-recall
Recall ChatCrystal memories for debugging tasks involving failing tests, compiler errors, runtime exceptions, dependency issues, environment breakage, or performance regressions. Use when historical root causes, fixes, or pitfalls may accelerate diagnosis before proposing a fix.
chatcrystal-task-recall
Recall project-first and global-supplement ChatCrystal memories before substantive implementation, refactoring, migration, configuration, investigation, or optimization work. Use when the task is non-trivial, has repository or project context, and prior fixes, decisions, pitfalls, or reusable patterns may change the…
