Sequential Thinking

What it does

When your agent uses it

• Complex planning requiring revision
• Hypothesis verification

Example prompts

• “Use the sequential-thinking skill to perform dynamic, reflective problem-solving through iterative thought chains”
• “/sequential-thinking”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Initial estimation: Start with an estimate of thoughts needed, but remain flexible
2. 2Iterative analysis: Work through thoughts sequentially while building context
3. 3Revision capability: Question or revise previous thoughts as understanding deepens
4. 4Branch exploration: Explore alternative approaches when needed
5. 5Hypothesis cycle: Generate hypotheses, verify against thought chain, repeat
6. 6Convergence: Continue until reaching a satisfactory solution

What it can do on your machine

Read from SKILL.md and the folder at commit 9e997ba. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sequential Thinking loads about 1.2k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~76

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Performs dynamic, reflective problem-solving through iterative thought chains. Use for complex planning requiring revision, branching, backtracking, or hypothesis verification. Ideal for multi-step analysis where context maintenance is required or the full scope isn't initially clear.

{
  "thought": "On reflection, thought 3's assumption about X was incorrect because Y...",
  "thoughtNumber": 6,
  "totalThoughts": 10,
  "isRevision": True,
  "revisesThought": 3,
  "nextThoughtNeeded": True
}

Thought [N/Total]: [Current thought content]
[If revision: "This revises thought X because..."]
[If branching: "Branching from thought X to explore..."]

[Continue with next thought when nextThoughtNeeded is True]

Final output after all thoughts complete:
Solution: [Clear, direct answer to the original problem]
