What it does
Working With Charts is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Guides consumers of @posthog/quill-charts through chart selection, data, themes, sizing, and composition. Use when adding or changing a chart built with the package, including its axes, tooltips, legend, overlays, or interactions. Links to package examples and API docs. Does not cover product integration or library internals.
Its SKILL.md is about 950 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 Data & Analytics, covering Technical documentation and Accessibility. It works with PostHog. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…
When your agent uses it

- Including its axes
Example prompts

- “/working-with-charts”
What it can do on your machine
Read from SKILL.md and the folder at commit 812e5c6. 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.
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
Working With Charts loads about 948 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 312 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 312 words (~948 tokens).
“Use the package's components and defaults before writing custom chart code. Read only the example or topic needed for the task. For changes inside the library, use CONTRIBUTING.md instead.”
