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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00202 |
| Opus 5 | $0.00007 | $0.00101 |
| Sonnet 5 | $0.00003 | $0.00040 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
goal-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 8d 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 it actually says
Goal Planner
Description
Takes a high-level goal or objective and breaks it down into a concrete, executable step-by-step plan with dependencies, milestones, and estimated effort.
When to Use
- When user says "I want to..." with a complex goal
- Project kickoff
- Quarterly planning
- Learning roadmap creation
Process
- Clarify the goal with targeted questions
- Identify constraints and dependencies
- Break goal into milestones
- Break milestones into tasks
- Estimate effort per task
- Identify critical path
- Save plan to context/
Output
Structured plan with: goal, milestones, tasks, dependencies, estimates
Agent Assignment
- Primary: opencode
- Fallback: agy
What ships with it
3 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.

goal-planner is a skill published in the GitHub repository modimihir07/agentic-os (166 stars, last pushed 27d ago), licensed MIT. It adds 14 tokens to every session and 202 once invoked, about $0.0001 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 2026-08-30.
