speckit-plan

speckit-plan is a skill for Claude Code, Codex from sarveshtalele/mcp-skills-registry. It costs 51 tokens per session (245 once invoked), scanned A, original, MIT.

A technical-planning tool that turns an approved specification into a plan.md file. The plan covers architecture, software parts, data structures, important decisions, and milestones.

In plain words
What is it for?
Use it to create an implementation plan from a specification, including system structure, data models, decisions, and milestones.
Why use it?
It connects feature requirements to an implementation approach before work is divided into tasks. This makes the intended design and major decisions reviewable.

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

speckit-plan 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 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/__init__.py, scripts/main.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

speckit-plan

Converts a spec summary into a plan.md. Then run speckit-tasks to break it into an executable backlog.

Files

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.

Changes

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.
