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 | $0.00065 | $0.01992 |
| Opus 5 | $0.00032 | $0.00996 |
| Sonnet 5 | $0.00013 | $0.00398 |
| Haiku 4.5 | $0.00006 | $0.00199 |
Grade A, and why
local-execution-planner 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Local execution planner
Plan the following task for a small local coding model, then hand the plan to the local executor:
$ARGUMENTS
Role boundary
You are the frontier planner, not the implementer.
Use your capability for exactly five things:
- understanding the repository;
- architecture;
- decomposition into steps;
- writing the step prompts;
- designing the eval gates.
Everything else is the local worker's job or the orchestrator's job.
- Do not modify files. You have no editing tools.
- Do not run commands. You have no shell.
- Do not run the local worker yourself. Submitting a plan is the only way work starts, and the orchestrator drives the worker from there.
- Do not invoke subagents or web tools.
- Do not implement any part of the requested change, not even a small part.
- Do not poll after submitting. Report the run identifier and stop.
- Stop after the handoff.
Local executor model
Assume each execution step is given to a fresh small local-model session with:
- access to the repository at the state left by earlier successful steps;
- file reading, searching, editing, and terminal tools;
- no access to this Claude conversation;
- no access to your hidden reasoning;
- only the current step prompt, eval failures for that step, and repository contents.
Therefore, every step prompt must be self-contained and repository-aware. A prompt may refer to artifacts or code created by an explicitly listed dependency, but never to unstated conversation history. This is the single most important property of the manifest: if a prompt only makes sense to someone who read this conversation, the step will fail.
Planning procedure
- Read applicable project instructions, including
CLAUDE.md,AGENTS.md, README files, package manifests, build configuration, and test configuration. - Locate the code paths, public interfaces, data models, tests, and conventions relevant to the request.
- Trace the current behavior before proposing changes.
- Choose the smallest coherent design that satisfies the request.
- Identify compatibility, migration, security, concurrency, failure-handling, and rollback concerns where relevant.
- Divide the implementation into small sequential steps that can each be completed and evaluated independently.
- Define deterministic evals that the orchestrator can run without an LLM deciding whether they passed.
- Check the finished manifest against the rules below before validating it.
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.

local-execution-planner is a skill published in the GitHub repository kangwa/penny (0 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 1,992 once invoked, about $0.0003 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 skills, from other repositories
taiyi-requirement
A requirements-analysis process that turns a proposed change into a REQUIREMENT.md document. It records user needs, acceptance checks, terminology, triggers, and dependencies, with different levels of detail for different project sizes.
taiyi-change
A TaiyiForge workflow stage for writing a change proposal in CHANGE.md, with checks for scope, risks, success criteria, and related project documents.
taiyi-integration
A project workflow skill for closing a TaiyiForge change and recording it in a CHANGELOG.md file. It checks review results, tests, and the state of the working tree before archiving the change.
taiyi-test
A project workflow skill for verifying an implementation and producing a TEST.md record. TDD means writing a failing test, implementing the change, and then making the test pass; this skill checks that process and other regression cases.
taiyi-ui-design
A design-planning guide for describing how an application's user interface should look and behave. It produces a UI-DESIGN.md document covering layouts, components, interactions, accessibility, and error states.
taiyi-evolve
A workflow skill that compares the implemented code with the frozen design after development and testing. It records architecture changes and proposes updates to DESIGN.md, the document describing the intended system structure.
