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 | $0.00009 | $0.00281 |
| Opus 5.5 | $0.00004 | $0.00112 |
| Sonnet 5.5 | $0.00002 | $0.00056 |
| Haiku 4.5 | $0.00001 | $0.00028 |
Grade A, and why
task-creator 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 1mo 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.

A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

task-creator is an agent published in the GitHub repository PlanVault/ai-engineering-playbook (6 stars, last pushed 1mo ago), with no licence file. It adds 9 tokens to every session and 281 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other agents, from other repositories
fixer
Applies code-review findings (Codex's, or the Claude seat's) to the code tree: reads the cited issues, makes the minimum targeted fix per finding, runs relevant verification, and reports the structured result. Dispatch when a code-review artifact with cited findings is ready to act on; open-ended cleanup with no cited…
reviewer
Fills a loop's reviewer seat with an adversarial Claude critique when the dispatching skill has seated Claude instead of Codex for this run (Codex's rate-limit budget is running ahead of the elapsed share of its window). Reads the target from disk exactly as the prompt names it, looks for ways to break it, and writes…
foundry-auditor
Read-only final quality gate for Foundry VTT changes. Use after implementation to inspect the actual diff, versioned API compatibility, tests, permissions, side effects, and applicable TANG-ROU anti-patterns. Reports findings only; never fixes them. Examples: Context: The coder has completed a macro change. user…
constitutional-validator
Validates specifications, plans, and implementations against the project constitution at .specify/memory/constitution.md.
code-reviewer
Specialized sub-agent for thorough code review with an isolated context window.
code-reviewer
Reviews implementation for correctness, security, maintainability, and project conventions.
