What it does
Py Code Insight Counters is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Count Python code insight work in tests with PyCodeInsightCounters.
Its SKILL.md is about 1.2k 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 Python and JetBrains IDEs. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.
Example prompts
- “/py-code-insight-counters”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Implement PyPerfProbe.Editor over the test fixture. FixtureEditor in PyNativeEngineCountersPerformanceTest is
- Create the probe with a disposable. The probe turns the counting on, turns off the RecursionManager test checks and
- Call one of these
- Call report(result). It prints PYPERF lines: the time quantiles, the allocations, the AST loads of the first
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
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
Py Code Insight Counters loads about 1.2k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 591 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 591 words (~1,237 tokens).
“PyCodeInsightCounters (python-psi-impl, package com.jetbrains.python.codeInsight) counts the work of the native Python type engine. PyPerfProbe (community/python/testFramework, package com.intellij.python.community.testFramework.performance) measures a scenario with these counters, the wall time, the allocations and the AST loads.”
