vigilante-issue-implementation-on-python

vigilante-issue-implementation-on-python is a skill for Claude Code, Codex from aliengiraffe/vigilante. It costs 36 tokens per session (714 once invoked), scanned A, original, Apache-2.0.

A workflow for implementing a GitHub issue from start to finish in a Python repository, following the project's existing coding and testing practices.

In plain words
What is it for?
It helps set up the project, format and lint changed files, run type checks, and test the affected code with tools such as pytest when the repository uses them.
Why use it?
It keeps the change focused on the issue and avoids imposing unfamiliar tools or repository-wide formatting changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vigilante-issue-implementation-on-python scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vigilante Python Issue Implementation

Focus

  • Read the prompt for detected tech stacks, process hints, and Python security guidance before changing code.
  • Follow idiomatic Python conventions already established by the repository and keep changes scoped to the issue.
  • Prefer the repository's existing environment, dependency, formatting, linting, typing, and test workflows over inventing a new stack.

Python Tooling Workflow

  • Environment: use the repository's documented bootstrap or environment workflow first. When no repo-specific workflow exists, prefer isolated environments such as venv rather than ad hoc global installs.
  • Formatting and linting: run the repository's established formatter and linter for touched files. When the repository already uses Ruff, prefer ruff format and ruff check; when it uses Black, use black. Do not introduce repo-wide formatting churn unrelated to the issue.
  • Typing: run the repository's existing typing checks when present, such as mypy, pyright-style tooling, or equivalent configured commands.
  • Testing: run targeted pytest or repo-standard test commands for the changed area first, then broaden scope when needed.
  • Dependency and package security: when dependency or packaging changes are involved, run repo-standard audit tooling. Use pip-audit when it is already part of the repo workflow or otherwise clearly available and relevant.
  • Dependencies: prefer standard library modules when they cover the need. Keep dependency manifests and lockfiles consistent when adding or updating packages.

Idiomatic Python

  • Follow existing project conventions for layout, imports, and naming instead of forcing a new style.
  • Prefer small, explicit functions, early returns, and straightforward exception handling.
  • Add or update docstrings only where the repository already expects them or where a public API change needs clear documentation.
  • Avoid broad cleanup or modernization unrelated to the issue.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
