agentic-stack is a portable layer of agent memory, skills, and protocols stored in a .agent/ folder that can be used across multiple coding-agent tools. It is for people who switch between agent harnesses while keeping shared knowledge and monitoring data. The catalogue entries provide skills and rules for this shared agent layer.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00002 | $0.00879 |
| Opus 5.5 | $0.00001 | $0.00352 |
| Sonnet 5.5 | $0.00000 | $0.00176 |
| Haiku 4.5 | $0.00000 | $0.00088 |
Grade A, and why
design-md 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DESIGN.md — portable visual system contract
Use this skill when a task touches Google Stitch's DESIGN.md format or
the project explicitly references its design system / design tokens. The
skill loads only when DESIGN.md exists at the project root (see
preconditions above), so general UI / frontend / component work that
isn't tied to a DESIGN.md won't trip it.
Source of truth
DESIGN.mdis a contract file. Read it before changing visual UI.- Treat YAML front matter tokens as normative values: colors, typography, spacing, radius, and component tokens are exact inputs to code.
- Treat the Markdown body as design rationale: it explains mood, hierarchy, interaction intent, and where tokens should or should not be used.
- If no
DESIGN.mdexists this skill is inactive; for new UI, offer to create one or ask for a brand/reference, but don't generate one unprompted.
Default: read-only
Do not modify DESIGN.md unless the user explicitly asks for a design
system change. Implementation work consumes the contract; it does not
edit it. Token additions, renames, or section restructures land in their
own commit with a clear message and (ideally) a Stitch round-trip.
Implementation rules
- Map tokens into the local styling system already in use: CSS variables, Tailwind theme values, design-token JSON, component props, or native styles.
- Use token references and component patterns from
DESIGN.mdinstead of hard-coded one-off values. - Keep accessibility constraints intact. Do not weaken contrast, focus, reduced-motion, or touch-target guidance unless the user explicitly asks.
When an edit IS authorised
- Preserve unknown headings and extra prose; other agents or Stitch may own them.
- Express component variants as related entries
(
button-primary,button-primary-hover, etc.). - Land token / structure changes in their own commit, separate from the feature consuming them.
Validation
- If Node/npm tooling is available, lint with:
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.

design-md is a skill published in the GitHub repository codejunkie99/agentic-stack (2,302 stars, last pushed 9d ago), licensed Apache-2.0. It adds 2 tokens to every session and 879 once invoked, about $0.0000 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.
