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 | $0.01813 | $0.01813 |
| Opus 5 | $0.00907 | $0.00907 |
| Sonnet 5 | $0.00363 | $0.00363 |
| Haiku 4.5 | $0.00181 | $0.00181 |
Grade C, and why
olddonkey-skills AGENTS.md scanned grade C with 2 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 6d 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.

What this repo is
A collection of Agent Skills (Markdown SOPs + helper Bash scripts) published
as both a Claude Code marketplace (.claude-plugin/marketplace.json) and a
Cursor marketplace (.cursor-plugin/marketplace.json). It is not a deployable
service. There are no repo-level dependency manifests (no package.json,
lockfile, or Makefile at the root); the toolchain — bash, git, Node.js/npm,
and python3 3.11+ (tomllib) — is expected to be preinstalled, so a startup
update script has nothing to install.
Components:
skills/implementation-loop/— the backend-neutral implementation loop skill. Uniform backend modules live underbackends/{codex,grok,cursor}/, each withdispatch.sh,runtime.md,selftest.sh, andfixture-driver.sh; grok also hasverify-worktree.sh.backends/backends.tsvregisters their capabilities. Shared suites and the opt-in real-backend gate live undertests/; the frozen Codex matrix istests/codex-cases.tsv.scripts/run-gate.shremains the backend-neutral gate, while the other eightscripts/*.shexecutables are one-release forwarding shims removed in 0.5.0. The shared observable interface is recorded inreferences/dispatch-contract.mdand enforced by the contract suites.skills/engineering-mode/— goal-first wrapper over the loop. Shared playbooks inreferences/playbooks/, plusscripts/tree-oid.shand its selftest.skills/web-slides/— a scaffolder (scripts/scaffold.sh) that generates a runnable Vite + React + TypeScript slide deck. The only runnable "app".cursor-implementation-loop/— the generated Cursor plugin port. It ships two skills (cursor-implementation-loop,cursor-engineering-mode) and two agents (agents/loop-implementer.md,agents/loop-independent-reviewer.md). Edit shared inputs underskills/or Cursor-authored inputs underhosts/cursor/, then runbash build.sh; do not hand-edit the generated tree. Manifest:.cursor-plugin/plugin.json.build.sh,hosts/cursor/,tests/build-{inventory.py,selftest.sh}— the deterministic Cursor-package generator, its host-only overlay, and its external-inventory/selftest tooling.bash build.sh --checkverifies the committed tree and its recorded version decision without rewriting it.install-cursor.sh/install-cursor-selftest.sh— root-level one-line installer for the Cursor plugin (curl … install-cursor.sh | bash), plus its own selftest.plans/,docs/— design plans and review records; prose only, no CI hooks.
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.

olddonkey-skills AGENTS.md is an instructions file published in the GitHub repository olddonkey/olddonkey-skills (16 stars, last pushed 18d ago), licensed MIT. It adds 1,813 tokens to every session, about $0.0091 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
