Apache Magpie is a framework of agent-assisted workflows for maintaining Apache software projects, including issue triage, pull-request review, contributor mentoring, and security-report handling. Apache maintainers and developers use it to delegate repetitive project work to coding agents while retaining human review. Its catalogue entries are the skills, instructions, plugin, and settings that implement these workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.08292 |
| Opus 5.5 | $0.00025 | $0.03317 |
| Sonnet 5.5 | $0.00012 | $0.01658 |
| Haiku 4.5 | $0.00006 | $0.00829 |
Grade B, and why
isolated-setup-install scanned grade B with 1 finding 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 today.
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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Runtime routing (run before the Claude-specific procedure)
Use the operator's explicitly requested runtime when supplied; otherwise use the active session's runtime. An installed executable or configuration directory alone does not select a runtime. For the routing below, treat that selection as the active harness.
Determine the active harness from the session metadata and executable. When it
is Codex, follow the install lifecycle in
docs/adapters/codex.md, including the
project profile merge, static lint, project trust, and agent-iso codex
steps. Do not write Claude settings or report a missing .claude file as a
Codex failure. After completing the Codex branch, stop; the remainder of this
skill is the Claude Code branch.
When the selected runtime is Antigravity, follow
docs/adapters/antigravity.md: resolve the installed plugin, snapshot, or framework checkout; propose the merge of the user-scope profile into ~/.gemini/antigravity-cli/settings.json and of the guard into ~/.gemini/config/hooks.json; then guide the wrapper launch and verification.
The setup is per user: write nothing into the repository.
Do not require or write Claude configuration.
After completing the Antigravity branch, stop before the Claude-specific procedure below.
When the selected runtime is Pi, follow
docs/adapters/pi.md: propose the one per-user package install, which brings the skills, the guard, the permission rules and the bash sandbox together; then guide the wrapper launch and verification.
The setup is per user: never install the package with -l and write nothing into the repository.
Do not require or write Claude configuration.
After completing the Pi branch, stop before the Claude-specific procedure below.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

isolated-setup-install is a skill published in the GitHub repository apache/magpie (128 stars, last pushed yesterday), licensed Apache-2.0. It adds 62 tokens to every session and 8,292 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
