What it does

Feature Exploration is an agent skill from pymc-labs/CausalPy. Explore unfamiliar APIs, libraries, or implementation behavior with minimal reproducible examples and documented findings. Use when implementation details are unclear and can be resolved by reading docs, inspecting code, and running focused experiments.

Its SKILL.md is about 440 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 PyMC. The repository describes itself as: A Python package for causal inference in quasi-experimental settings. The licence is Apache-2.0.

When your agent uses it

  • Implementation details are unclear and can be resolved by reading docs
  • Inspecting code
  • Running focused experiments

Example prompts

  • “/feature-exploration”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. State the uncertainty: name the API, behavior, or integration detail that needs proof.
  2. Read the closest authoritative docs or source code before experimenting.
  3. Build the smallest reproducible example that answers the question.
  4. Run it in the project environment when it imports project code or dependencies.
  5. Iterate only until the behavior is understood.
  6. Record the finding in the final answer or in the durable project docs if it affects future work.
  7. Apply the production change using the confirmed behavior.

What it can do on your machine

Read from SKILL.md and the folder at commit f17b30f. 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

Feature Exploration loads about 442 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 214 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~442

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.

Feature Exploration

Use this developer skill when a task depends on API behavior that is unclear from memory or partially documented. The goal is to resolve uncertainty before changing production code.

Workflow

  1. State the uncertainty: name the API, behavior, or integration detail that needs proof.
  2. Read the closest authoritative docs or source code before experimenting.
  3. Build the smallest reproducible example that answers the question.
  4. Run it in the project environment when it imports project code or dependencies.
  5. Iterate only until the behavior is understood.
  6. Record the finding in the final answer or in the durable project docs if it affects future work.
  7. Apply the production change using the confirmed behavior.

Guardrails

  • Do not create throwaway files in tracked locations. If a temporary note is needed, use .scratch/.
  • Do not leave exploratory scripts behind unless they become real tests or documented examples.
  • Prefer adding a proper test under causalpy/tests/ when the discovered behavior is important to preserve.
  • Keep experiments narrow; avoid broad refactors while investigating.
  • Follow the repository environment rules in AGENTS.md for commands that import CausalPy, PyMC, PyTensor, matplotlib, or repo tooling.

Output

When using this skill, report:

  • The uncertainty investigated.
  • The evidence gathered.
  • The conclusion.
  • Any production change or test that now relies on that conclusion.

To copy it by hand, put the folder in .cursor/skills/feature-exploration, .gemini/skills/feature-exploration, .github/skills/feature-exploration and .opencode/skills/feature-exploration in your project.

What does Feature Exploration need to run?

SKILL.md names no scripts, command-line tools or credentials: Feature Exploration is instructions for the agent only.

Does Feature Exploration access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
