Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00423 |
| Opus 5 | $0.00023 | $0.00211 |
| Sonnet 5 | $0.00009 | $0.00085 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
multica-artifact-design-sync 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 10d 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.
What it actually says
Artifact · Technical Design Sync
Purpose
Land technical design docs to the team's unified technical-doc location and let downstream retrieve them via a stable reference.
This skill decouples "platform integration" from "role prompt": the role prompt only says "produce technical design", not which platform. Changing companies means editing only this skill, not the @Architect prompt.
Default platform: Git repo / Confluence (choose one per team convention)
- Output: technical design (current arch, proposed change, affected components, steps, verification plan, risks).
- Upload A (Git repo): place under the repo's agreed doc dir (e.g.
docs/design/<issue-id>.md), reviewed together with the code PR — traceable. - Upload B (Confluence): create / update a technical design page, return the link.
- Retrieve: downstream @FrontendDev / @BackendDev / @Tester read via the file path or page link.
Content spec (platform-independent part)
Per multica-technical-design skill: current architecture, minimal viable change, affected components, implementation steps, verification plan, risks. Keep stable headings and ids.
Usage (role side writes only this line)
@Architect: "Produce technical design, land it via
multica-artifact-design-syncskill to the team's agreed location (Git / KB), and return the reference."
Swap platform (no role-prompt change)
Replace this skill's "default platform" section with your tool (internal Wiki / Notion / Feishu), keeping the "upload + return stable reference" interface unchanged.
Why it works
Design-doc locations vary by team (some in repo, some in Wiki). Sinking it into the skill keeps the role's "what to produce" description stable while the location swaps with the skill.
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.

multica-artifact-design-sync is a skill published in the GitHub repository it235/multica-best-practices (108 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 423 once invoked, about $0.0002 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.

workthreads
SpecStory Workthreads - a weekly work-thread rollup across a team's repos from SpecStory coding histories (any agent - Claude Code, Codex, Cursor, Gemini, and more). It groups the window's sessions into threads of work per project and labels each new / open / recently closed, so a lead sees what shipped, what is still…

Validate that a story file is implementation-ready. Checks for embedded GDD requirements, ADR references, engine notes, clear acceptance criteria, and no open design questions. Produces READY / NEEDS WORK / BLOCKED verdict with specific gaps. Use when user says 'is this story ready', 'can I start on this story', 'is…
