agent-prompts

agent-prompts is a skill for Claude Code from jsegov/shipspec-claude-code-plugin. It costs 59 tokens per session (1,984 once invoked), scanned A, original, MIT.

A tool for turning product requirements and technical designs into small, ordered task descriptions that coding agents can execute. It also creates machine-readable and human-readable task files.

In plain words
What is it for?
Use it to create implementation tasks from PRD files (product requirement documents) and SDD files (technical design documents), including acceptance checks and task dependencies.
Why use it?
It removes the need to manually break a large feature into detailed work items and keep their dependencies organized.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00059 $0.01984
Opus 5 $0.00030 $0.00992

Security

Grade A, and why

agent-prompts 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.

Agent Prompt Generation

Create structured task prompts that coding agents can execute effectively.

Output Files

Task generation produces two files:

File Purpose Used By
TASKS.json Machine-parseable metadata Plugin agents, hooks, commands
TASKS.md Human-readable task prompts Developers, code review

Source of Truth: TASKS.json is authoritative. TASKS.md is a derived human-readable view.

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.
