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 | $0.00071 | $0.01444 |
| Opus 5.5 | $0.00028 | $0.00578 |
| Sonnet 5.5 | $0.00014 | $0.00289 |
| Haiku 4.5 | $0.00007 | $0.00144 |
Grade A, and why
reasoning-system 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.
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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reasoning System
Structured reasoning immediately before you write or edit code—parallel in role to the Memory System skill for task memory. This workflow is the reasoning system; invoke the sequentialthinking tool for each thought step (see Step 2). Your agent host may register it under different server names; the tool identifier to call is sequentialthinking.
When to Use
Invoke after planning but before writing/editing code:
- Implementing new features or modules
- Refactoring existing code
- Complex architectural decisions
- Changes affecting multiple files
Instructions
Step 1: Identify Relevant Documents
Select applicable documents from /docs/agents/ based on task type. See references/document-mapping.md for detailed mapping.
This step produces a candidate set of sources. Thought 2 (Retrieval) turns that into a concrete list: which docs to open, which task memory to recall, and which parts of the codebase to search or read.
Quick reference:
| Task Type | Primary Documents |
|---|---|
| New feature | Requirements, App Flow, Tech Stack |
| Refactor | Coding Standards, File Structure, Server Structure |
| Bug fix | Testing Guidelines, Server Structure |
| UI work | Client Guidelines, App Flow |
Step 2: Invoke the sequentialthinking tool
Call sequentialthinking with the parameters below. Server or package names differ by host; use the registration that exposes this tool identifier in your environment.
| Parameter | Value |
|---|---|
thought |
Current reasoning with doc references, constraints, alternatives |
thoughtNumber |
Current step (1, 2, 3...) |
totalThoughts |
Estimated steps (typically 5–7; adjust up or down as you go) |
nextThoughtNeeded |
true if more reasoning is needed |
Optional parameters on the tool (e.g. revision or branching) may be used when you need to reconsider an earlier thought; they are not required for a linear pass.
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.

reasoning-system is a skill published in the GitHub repository atebites-hub/PJTemplate (2 stars, last pushed 16d ago), licensed MIT. It adds 71 tokens to every session and 1,444 once invoked, about $0.0003 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 2026-08-31.
