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.

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 | $0.00035 | $0.00316 |
| Opus 5.5 | $0.00014 | $0.00126 |
| Sonnet 5.5 | $0.00007 | $0.00063 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
planning 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 1mo 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
Planning and Estimation (WHAT)
Use this skill when work needs planning, breakdown, estimation, or capacity validation before it becomes final backlog content.
Default guardrails
- Apply
output-handshakebefore producing any final planning artifact: ask where it should live and confirm human review. - Prefer project-specific planning rules if the repo, ticket system, or engagement pack defines them. Otherwise use this default.
- If a work item is being created or refined, pair this with
work-itemand the relevant atomic skill.
What to check
- Scope and goal are clear.
- Work is broken down into manageable items; anything estimated at 5+ points should be considered for splitting.
- Acceptance criteria and dependencies are known enough for estimation.
- Estimation technique is explicit: planning poker, T-shirt sizing, Fibonacci, or the team override.
- Capacity considers availability, holidays, meetings, focus factor, dependencies, and historical velocity.

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.
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.

planning is a skill published in the GitHub repository ulises-jeremias/agent-toolkit (19 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 316 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-04.
