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.

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 | $0.00113 | $0.02199 |
| Opus 5 | $0.00056 | $0.01099 |
| Sonnet 5 | $0.00023 | $0.00440 |
| Haiku 4.5 | $0.00011 | $0.00220 |
Grade A, and why
ux-activity-feed 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.

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Activity Feed Skill
How this skill behaves (read first)
This is a generative skill. A feed's job is to surface what matters and let the noise fade — and the defaults work against that: each entry crammed with every available field, loud exact timestamps, every social control on every row, ungrouped notifications buzzing one-by-one, and a blank feed greeting brand-new users in the exact window where they decide whether to stay. There's also a consequential upfront choice — chronological vs. algorithmic/ranked — that teams often make by accident. So this skill gates:
- Establish the feed type and what the feed is for — chronological vs. ranked is hard to change later and reshapes everything downstream.
- Apply the always-true core — curate each entry, keep text legible, downplay timestamps, never show an empty feed, show refresh status.
- Surface the context-dependent decisions (notification aggregation, follow recommendations, per-entry controls) with trade-offs.
Then it hands off to ux-aesthetics-audit, ux-heuristics-audit, ux-accessibility-audit, ux-microcopy-audit, ux-dark-patterns-audit, and ux-mobile-responsiveness-audit for validation.
Scope & composition (per docs/orchestration-policy.md §9): this skill covers the feed screen and its entries and composes lower-scope skills rather than re-deriving them. Core children (built as part of the feed): per-entry card anatomy via ux-cards. Peers that own a sub-part (defer): notification component behavior to ux-notifications-and-toasts and loaders/skeletons to ux-loaders-and-progress (they own those sub-parts if reached). Downstream (offer, don't auto-build): the empty-feed screen craft via ux-empty-states. Inherit, don't regenerate: under an existing design system, take color/type/spacing from its tokens — only set those when designing from scratch.
Step 0 — Establish context before designing
Ask if not known; state the assumption if proceeding without an answer:
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.

ux-activity-feed is a skill published in the GitHub repository Uxcel-Lab/product-skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 113 tokens to every session and 2,199 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 2026-08-31.
