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 | $0.00050 | $0.00957 |
| Opus 5 | $0.00025 | $0.00478 |
| Sonnet 5 | $0.00010 | $0.00191 |
| Haiku 4.5 | $0.00005 | $0.00096 |
Grade A, and why
sequential-thinking 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 6d 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.
This is a copy
100% identical to sequential-thinking — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Sequential Thinking
A structured approach to complex problem-solving that breaks down challenges into iterative thought steps with built-in flexibility for revision and course correction.
When to Use This Skill
- Breaking down complex problems into manageable steps
- Planning and design requiring iterative refinement
- Analysis that might need course correction mid-stream
- Problems where the full scope emerges during analysis
- Multi-step solutions requiring context across steps
- Filtering out irrelevant information
- Hypothesis generation and verification workflows
Core Methodology
Sequential thinking follows a dynamic process:
- Initial estimation: Start with an estimate of thoughts needed, but remain flexible
- Iterative analysis: Work through thoughts sequentially while building context
- Revision capability: Question or revise previous thoughts as understanding deepens
- Branch exploration: Explore alternative approaches when needed
- Hypothesis cycle: Generate hypotheses, verify against thought chain, repeat
- Convergence: Continue until reaching a satisfactory solution
Instructions
Thought Structure
Each thought in the sequence should include:
- thought: Current thinking step content
- thoughtNumber: Position in sequence (1, 2, 3, ...)
- totalThoughts: Current estimate of total thoughts needed (adjustable)
- nextThoughtNeeded: Whether another thought step is required
Optional revision/branching metadata:
- isRevision: Boolean indicating if reconsidering previous thinking
- revisesThought: Which thought number is being revised
- branchFromThought: Branching point thought number
- branchId: Identifier for current branch
- needsMoreThoughts: Flag when reaching end but requiring more analysis
Process Guidelines
Starting out:
- Estimate initial thoughts needed based on problem complexity
- Begin with thought 1, establishing context and approach
- Set totalThoughts conservatively; you can adjust later
What ships with it
1 file 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.

sequential-thinking is a skill published in the GitHub repository irahardianto/qurio (17 stars, last pushed 6mo ago), licensed MIT. It adds 50 tokens to every session and 957 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to sequential-thinking, differing in 0 lines, and is treated as a copy.
