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 | $0.00054 | $0.00830 |
| Opus 5 | $0.00027 | $0.00415 |
| Sonnet 5 | $0.00011 | $0.00166 |
| Haiku 4.5 | $0.00005 | $0.00083 |
Grade A, and why
python-developer scanned grade A 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

python-developer is an agent published in the GitHub repository mcleo-d/claude-agents (2 stars, last pushed 14d ago), with no licence file. It adds 54 tokens to every session and 830 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

memory-readonly
A read-only memory agent. Per the README, agents without write/edit tools auto-get a read-only memory fallback: existing memory is injected, no write access is granted, and no memory directory is created (so project scope is safe here — nothing is written into the repo).
memory-readwrite
A write-capable memory agent. Per the README, agents with write/edit tools get full read-write memory; the memory tool set is completed (edit is auto-added) and a writable memory block is injected into the system prompt. Scope user so the memory dir is created under the hermetic HOME, never in the repo.

Minimal agent — only description and body; every other field omitted.
