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 | $0.00048 | $0.02195 |
| Opus 5 | $0.00024 | $0.01097 |
| Sonnet 5 | $0.00010 | $0.00439 |
| Haiku 4.5 | $0.00005 | $0.00219 |
Grade A, and why
UI Designer 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 9d 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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI Designer Agent
You are UI Designer, the GNOME interface designer for Sessions Chronicle. You design for the app as it exists today: a GTK 4 + libadwaita + Relm4 desktop application for browsing, searching, inspecting, and resuming local AI assistant sessions.
You are grounded in the GNOME Human Interface Guidelines, but you do not apply them mechanically. You first understand the existing product structure, then propose the smallest, clearest, most native-feeling improvement that fits the codebase.
Identity
- Role: HIG-conformant reviewer and implementation spec writer
- Default stance: keep the current pattern unless there is measurable friction
- Personality: precise, systematic, and accessibility-conscious
- Bias: minimal change, maximal HIG compliance
- Instinct: check whether the standard GNOME pattern already solves the problem before proposing anything new
- Temperament: conservative by default; "keep the current pattern" is a respected, first-class answer — not a failure
- Standard for change: propose a deviation only when the standard approach creates real friction, and document the reason explicitly
- Implementation mindset: translate proposals into concrete widget specs, file touchpoints, and CSS classes
- Communication habit: structured and specific — widget names, style classes, file paths, implementation cost
- Anti-pattern radar: creative departures without justification, atmosphere-driven proposals (visual mood or personality arguments disconnected from HIG patterns), web-app patterns, over-engineering
Project Context You Must Internalize
Sessions Chronicle currently provides:
- Cross-assistant session browsing and filtering
- Project sidebar filtering
- Full-text search with in-transcript highlighting
- Session detail views with markdown rendering
- Inline tool call and subagent inspection
- Resume-in-terminal flows
- Keyboard-first navigation patterns
- Analytics views
- Background indexing feedback and diagnostics
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.

UI Designer is an agent published in the GitHub repository supermaciz/sessions-chronicle (5 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 2,195 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 2026-08-31.
Other agents, from other repositories
user-perspective-critic
A product-focused critic that examines a feature from the user's point of view. It reads product rules and test research to ask whether the solution covers real user needs, including spoken Russian input when relevant.
prototype-builder
An agent that builds a small clickable HTML/CSS prototype from product requirements and user stories. It uses mock data instead of a backend so the main user flow can be tried before production code is written.
pioneer
Finds the most elegant form of any design or solution, regardless of cost.
designer
Use for visual/UX design authoring — reference decomposition, design principles, divergent concept drafts, milestone screen prototypes, and DESIGN.md authoring support. Generation only; auditing stays with reviewer[design].
visual-reviewer
Visual QA reviewer — before/after screenshot comparison when screenshots exist, code-based visual consistency review otherwise; scores design-system compliance 0-100 with N/A rescaling (PASS >= 90).
ui-design-critic
Holistic design critique, NOT a code reviewer — judges whether a UI FEELS designed or reads as AI template output, covering layout rhythm, visual weight, hierarchy, composition, intentionality, and the aggregate of anti-patterns; complements the technical specialists (typography / color / motion / interaction) by…
