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 | $0.00059 | $0.03907 |
| Opus 5.5 | $0.00024 | $0.01563 |
| Sonnet 5.5 | $0.00012 | $0.00781 |
| Haiku 4.5 | $0.00006 | $0.00391 |
Grade A, and why
ds-context 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.
How it starts
The opening of the file, as written. The whole thing — 321 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guard: not a git repo
If GIT_ROOT is . (meaning git could not find a project root), stop immediately and say:
"I don't see a project here. Make sure you open Claude Code from your project folder — the one that has your
src/orpackage.json. Then run/ds-contextagain."
Do not continue past this point if GIT_ROOT is ..
Opening line (always show this, never the raw preamble output)
"Looking at your project..."
What this skill does
You're building the Design Bible — a living file at design/DESIGN-BIBLE.md that holds everything about how this project looks and feels. Every other designStack skill reads from it. Once it exists, you never have to explain your brand again.
This takes about 5 minutes.
Step 0 — Auto-scan code files
Before asking the user anything, read these files silently (do not show the raw contents to the user):
- CSS custom properties — look for the first file that exists:
src/app/globals.cssapp/globals.csssrc/index.csssrc/styles/globals.cssRead it and extract every--variable: valuepair from the:rootblock. Note colors, fonts, spacing tokens.
What ships with it
2 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.

ds-context is a skill published in the GitHub repository harshii0509/designStack (13 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 3,907 once invoked, about $0.0002 per session on Opus 5.5. 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.
