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 | $0.00022 | $0.00302 |
| Opus 5 | $0.00011 | $0.00151 |
| Sonnet 5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
planning-and-task-breakdown 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 7d 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-task-breakdown
When To Use
- A spec exists and needs implementation steps.
- Work spans multiple files or phases.
- The change needs to be split for reviewability.
Workflow
- Restate the target outcome and constraints.
- Identify dependencies and risky unknowns.
- Break work into vertical slices that each produce observable progress.
- Keep each task small enough to review independently.
- Define acceptance criteria and verification for each task.
- Order tasks to de-risk early and avoid large hidden integration steps.
- Mark tasks that need user confirmation, external credentials, or production access.
Anti-Rationalization
| Excuse | Rebuttal |
|---|---|
| "I'll just do it all at once." | Large changes hide defects and are hard to review. |
| "The tasks are obvious." | If they are obvious, they are cheap to write down. |
| "Testing can be one final step." | Verification belongs to each slice, not just the end. |
Verification
- Every task has an outcome, acceptance criteria, and check.
- Dependencies are explicit.
- No task requires unrelated refactoring to be reviewable.
Exit Criteria
- Implementation can proceed one slice at a time with clear stopping points.
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-and-task-breakdown is a skill published in the GitHub repository Plazmodium/odin-workflow (0 stars, last pushed 3mo ago), licensed MIT. It adds 22 tokens to every session and 302 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 2026-09-01.
Other skills, from other repositories
b123d-modeling
Use this skill when asked to model, build, or modify a 3D part or assembly with build123d — from a text description, a technical drawing (image or PDF), dimensions in a spec, or an existing STEP/STL file.
b123d-edit
Use this skill when the task is to change an existing build123d model or script: "make this bracket 5 mm taller", "move the holes inward", "add a counterbore", "remove this rib", "make it fit this mating part", or "repair the code so the intended edit remains parametric".
