At a glance

Implement PolyContext feature gating and environment detection.

  • SKILL.md covers Two location overloads, PolyContextProvider —…, Context rules — the… and .ws-context — user override file, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Poly Context is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Implement PolyContext feature gating and environment detection.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Ruby. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.

Example prompts

  • “/poly-context”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 562e3a2. 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 kotlin).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • plugins.jetbrains.com

    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

Poly Context loads about 2k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 825 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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 825 words (~2,045 tokens).

“PolyContext answers "what coding environment am I in right now." It is a standalone platform mechanism — poly-symbols is its biggest consumer (gating which PolySymbolQueryScopeContributor/QueryConfigurator registrations apply), but PolyContext itself has no dependency on PolySymbols or on web frameworks being…”
