refresh-json-dataRefresh token estimator and model pricing JSON files with latest data from AI model providers
Refresh JSON Data is an agent skill from rajbos/ai-engineering-fluency. Refresh token estimator and model pricing JSON files with latest data from AI model providers
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: Extension that shows information about the estimated token usage and more of AI in editors/CLI's. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 6933e2a. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
npmgitFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
json-schema.orgAlso links to:
openrouter.aidocs.github.comopenai.comanthropic.complatform.claude.comai.google.devx.aipricepertoken.comai-pricing.infocode.visualstudio.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Refresh JSON Data loads about 1.4k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 545 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.
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.

.claude/skills/refresh-json-data/SKILL.md (or your agent's skills folder).This skill helps you update the token estimation ratios and model pricing data in the AI Engineering Fluency extension.
The extension uses two JSON data files that need periodic updates:
These files are located in src/ directory and are bundled into the extension at build time.
Use this skill when you need to:
Before updating these files, ensure you have:

"$schema": "http://json-schema.org/draft-07/schema#",
"description": "Character-to-token ratio estimators for different AI models.",
"estimators": {

Validation:
Validate JSON syntax, run npm run compile && npm run test:node (do not
launch VS Code or the Extension Development Host — that is a manual,
human-only debugging step; see .github/copilot-instructions.md), review
with git diff, then commit/push as usual.
esbuild.jsnpm run compile after changessrc/README.md for additional detailsExtension not loading updated data:
npm run compilenpm run test:node passesThe extension reads these files at compile time via:
import tokenEstimatorsData from './tokenEstimators.json';
import modelPricingData from './modelPricing.json';The data is then used in the CopilotTokenTracker class:
tokenEstimators - Used for token estimation from character countsmodelPricing - Used for cost calculations in the details panelBoth files must maintain their structure to ensure the extension compiles and runs correctly.

Refresh token estimator and model pricing JSON files with latest data from AI model providers. Refresh JSON Data is an agent skill from rajbos/ai-engineering-fluency.
Refresh JSON Data fits situations like: development work in your project.
Run `npx skills add rajbos/ai-engineering-fluency --skill refresh-json-data -a claude-code`. Or copy the skill folder (.claude/skills/refresh-json-data in rajbos/ai-engineering-fluency) into .claude/skills/refresh-json-data in your project. Claude Code loads it when a task matches its description.
Run `npx skills add rajbos/ai-engineering-fluency --skill refresh-json-data -a codex`. Or copy the skill folder (.claude/skills/refresh-json-data in rajbos/ai-engineering-fluency) into .agents/skills/refresh-json-data in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add rajbos/ai-engineering-fluency --skill refresh-json-data -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/refresh-json-data, .gemini/skills/refresh-json-data, .github/skills/refresh-json-data and .opencode/skills/refresh-json-data in your project.
Going by SKILL.md and its folder, Refresh JSON Data needs the command-line tools its instructions call (npm and git). Our summary lists: Node.js.
SKILL.md names 11 domains. In commands or code: json-schema.org; the agent is likely to contact it when it follows the instructions. As links in the text: openrouter.ai, docs.github.com, openai.com, anthropic.com, platform.claude.com, ai.google.dev, x.ai, pricepertoken.com, ai-pricing.info and code.visualstudio.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Refresh JSON Data is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
