What it does
Modifying Theme JSON is an agent skill from data-goblin/power-bi-agentic-development. Design, enforce, audit, and validate Power BI report themes through the pbir CLI. Invoke when a report uses a default or minimal theme, visuals have inconsistent formatting or many local overrides, or the user asks to create, copy, apply, standardize, rebrand, audit, or validate a theme; change theme colors or typography; define style presets; promote visual formatting into the theme; clear overrides; or improve theme compliance.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 55 other files, including reference files (for example `examples/DataGoblins2021.json`, `examples/Fluent2-CY26SU03.json` and `examples/visualTypes/actionButton.md`).
It sits in Data & Analytics, covering Brand strategy and identity and Typography. It works with Power BI. The repository describes itself as: Power BI AI skills and Power BI agents for Claude Code and GitHub Copilot: a plugin marketplace of Power BI skills, subagents, and hooks for semantic models, DAX, TMDL, reports… The licence is GPL-3.0.
When your agent uses it
- Tasks that involve Brand strategy and identity
- Tasks that involve Typography
Example prompts
- “/modifying-theme-json”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Limit the data palette to the number of categories the report genuinely needs.
- Reserve saturated accent colors for focus, selection, exceptions, and key comparisons.
- Assign one stable meaning to each semantic color. Good, neutral, bad, selected, disabled, and hyperlink colors must not trade roles across…
- Keep structural colors quiet. Axes, borders, gridlines, and backgrounds should support reading rather than compete with data.
- Use one portable font family and a small type scale. Express hierarchy through size and weight, not many colors.
- Prefer wildcard defaults, then visual-type defaults, then rare instance overrides.
- Preserve accessible contrast and never rely on hue alone to communicate state.
What it can do on your machine
Read from SKILL.md and the folder at commit a301717. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Modifying Theme JSON loads about 1.7k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 557 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Design, enforce, audit, and validate Power BI report themes through the pbir CLI. Invoke when a report uses a default or minimal theme, visuals have inconsistent formatting or many local overrides, or the user asks to create, copy, apply, standardize, rebrand, audit, or validate a theme; change theme colors or typography; define style presets; promote visual formatting into the theme; clear overrides; or improve theme compliance.
Power BI report themes
Use this skill for theme design and compliance decisions. Use the pbir-cli skill for command details.
Non-negotiable tooling rule
Use pbir for every report and theme mutation. Never edit theme.json, visual.json, serialized .Theme fragments, or other report JSON directly. Never fall back to jq, shell replacement, or a JSON-editing skill. If pbir lacks the required operation, stop and report the missing capability.
Read JSON only through pbir cat, pbir get, or read-only examples. Prefer structured CLI inspection commands because they explain the formatting cascade and usage.
Why themes matter
A theme centralizes formatting that would otherwise drift across visuals. It should own repeated choices such as:
- Data-series palette and semantic good/neutral/bad colors
- Background, foreground, structural, gradient, hyperlink, and null colors
- Font family, size, weight, and hierarchy
- Wildcard container defaults such as titles, borders, padding, and shadows
- Visual-type defaults for cards, slicers, charts, tables, textboxes, and images
Visual-level overrides should remain only for content-specific exceptions or conditional formatting. Theme-first reports are easier to rebrand, diff, and maintain.
Formatting cascade
Power BI defaults
-> theme wildcard defaults
-> theme visual-type defaults
-> selected style preset
-> visual instance overridesThe last layer wins. Diagnose unexpected rendering with pbir visuals format, which reports the effective value and source; do not inspect or patch visual.json.
Audit before changing
pbir theme colors "Report.Report"
pbir theme fonts "Report.Report"
pbir color list "Report.Report"
pbir fonts list "Report.Report"
pbir visuals format "Report.Report/Page.Page/Visual.Visual"
pbir bpa run "Report.Report"Look for hard-coded colors, repeated visual-level font or container overrides, inconsistent visual types, weak contrast, excessive palette size, and sentiment colors that change meaning between visuals.
Design rules
- Limit the data palette to the number of categories the report genuinely needs.
- Reserve saturated accent colors for focus, selection, exceptions, and key comparisons.
- Assign one stable meaning to each semantic color. Good, neutral, bad, selected, disabled, and hyperlink colors must not trade roles across pages.
- Keep structural colors quiet. Axes, borders, gridlines, and backgrounds should support reading rather than compete with data.
- Use one portable font family and a small type scale. Express hierarchy through size and weight, not many colors.
- Prefer wildcard defaults, then visual-type defaults, then rare instance overrides.
- Preserve accessible contrast and never rely on hue alone to communicate state.

pbir theme set-formatting "Report.Report" "*.*.border.show" --value false
pbir theme set-formatting "Report.Report" "card.*.title.fontSize" --value 14Run pbir schema describe <visualType> <object> before authoring unfamiliar formatting properties.
Promote a good visual into the theme
pbir theme push-visual "Report.Report/Page.Page/BestCard.Visual" --dry-run
pbir theme push-visual "Report.Report/Page.Page/BestCard.Visual"Use this when a well-designed instance should become the default for its visual type. Inspect the dry run first so content-specific formatting is not promoted accidentally.
Enforce theme inheritance
Clearing overrides is destructive and must be confirmed with the user. Preserve conditional formatting unless the user explicitly wants it removed.
pbir visuals clear-formatting "Report.Report/**/*.Visual" --keep-cf --dry-run -f
pbir visuals clear-formatting "Report.Report/**/*.Visual" --keep-cf -f
pbir theme colors "Report.Report" --normalize
pbir theme colors "Report.Report" --normalize --applyFor selective cleanup, use the flags documented by pbir visuals clear-formatting --help rather than broad file edits.
Copy or replace a theme
pbir cp "Source.Report/theme" "Target.Report/theme" -f
pbir theme validate "Target.Report"After a theme swap, clear stale visual overrides, normalize surviving color literals, and inspect foreground/background polarity so text does not become invisible.
Validate and render
Use one confidence pass after a coherent batch:
pbir theme validate "Report.Report"
pbir validate "Report.Report" --all
pbir desktop refresh "Report.Report"
pbir desktop screenshot "Report.Report" --all --output-dir screenshotsDesktop refresh does not reload theme resources. Close and reopen the report before judging theme changes, then capture screenshots. If Desktop is unavailable, ask before publishing to a sandbox workspace for rendered verification.
