composer-planner

composer-planner is an agent for coding agents from FrkAk/piyaz. It costs 129 tokens per session (3,791 once invoked), scanned A, original, AGPL-3.0.

A planning agent for the Piyaz Composer workflow. It turns a research brief into a detailed implementation plan and moves the task from draft to planned.

In plain words
What is it for?
Use it during the planning phase of a Piyaz task, after research and before an implementer starts coding.
Why use it?
It fills gaps in earlier research and records the plan in Piyaz, giving implementation work a clear starting point.

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.

agentmods
npx agentmods add agents/frkak/piyaz/composer-planner
Clone the repo
git clone --depth 1 https://github.com/FrkAk/piyaz

Or install piyaz, the plugin that ships this one along with the rest of its 1 skill, 10 agents, 1 MCP server.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

composer-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 5d 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 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.
