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 | $0.00006 | $0.00198 |
| Opus 5 | $0.00003 | $0.00099 |
| Sonnet 5 | $0.00001 | $0.00040 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
rustyspec-implement 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 2d 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.
What it actually says
Read the project context from .rustyspec/AGENT.md, then implement the feature.
The feature ID is: $ARGUMENTS Find the matching directory under specs/ (e.g. specs/001-feature-name/).
Steps:
- Read the feature's tasks.md for the task list
- Read the feature's spec.md for requirements and acceptance criteria
- Read the feature's plan.md for architecture decisions
- Execute each task in order, respecting phase dependencies
- Tasks marked [P] can be done in parallel
- After completing each task, update tasks.md: change
- [ ]to- [x]for that task - When all tasks are done, run /rustyspec-analyze to validate
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.

rustyspec-implement is an agent published in the GitHub repository jyjeanne/rustyspec (5 stars, last pushed 4mo ago), licensed MIT. It adds 6 tokens to every session and 198 once invoked, about $0.0000 per session on Opus 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
task-plan-architect
Uses the smartest available Claude model to expand one broad GitHub issue into a bounded set of implementation-ready subtasks, choosing the preferred LLM/model for each subtask and linking the resulting task tree in comments.
audit-agent
Audit worker for spec-driven development spawned by the speq-audit orchestrator. Verifies specs/mission.md against the real spec library and returns the inconsistencies. Read-only — authors nothing.
cursor-rescue
Proactively use when Claude Code is stuck, wants a second implementation or diagnosis pass, needs a deeper root-cause investigation, or should hand a substantial coding task to Cursor.
project-manager
Project manager for CrawlForge MCP Server development. Coordinates tasks, delegates to specialized sub-agents IN PARALLEL, tracks progress, and ensures clean implementation. Use PROACTIVELY for any multi-step project coordination.
application-patterns-wave-06
Wave 06 adds practical workflows for agency operations, clinical drafting, privacy, content, data, infrastructure, education, commerce, finance, people, insurance, legal review, operations, product, research, and security. Every pattern below uses synthetic input and is a starting point for inspection, not evidence of…
mach12:code-explorer
Deeply analyzes existing codebase features by tracing execution paths, mapping architecture layers, understanding patterns and abstractions, and documenting dependencies to inform new development.
