What it does
Project Planner is an agent skill from modimihir07/agentic-os. Detailed implementation plans and spec-driven development
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `eval.json`, `learnings.md` and `score-history.json`).
It sits in Agent Workflows, covering Planning and Spec-driven development. The repository describes itself as: Agentic OS: Multi-agent orchestration platform for opencode, Hermes & Gemini CLI. Skills hub, scheduler, cost analytics, memory & backup. The licence is MIT.
When your agent uses it
- Tasks that involve Planning
- Tasks that involve Spec-driven development
Example prompts
- “/project-planner”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Brainstorm and refine requirements
- Read standards/ for project conventions
- Create spec document with screens and data model
- Break into tasks (2-5 minutes each)
- Each task has: file path, code template, verification step
- Save spec and plan to context/
What it can do on your machine
Read from SKILL.md and the folder at commit c7ebbb4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Project Planner loads about 226 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 100 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
