sw-pivot

sw-pivot is a skill for Claude Code from Obsidian-Owl/specwright. It costs 29 tokens per session (1,628 once invoked), scanned A, original, MIT.

A guided way to revise a design or plan when the work changes. It records what remains valid, explains the change, and updates the affected work documents.

In plain words
What is it for?
Use it to replan unfinished work after new research, changed requirements, or a design problem, then return the work to planning or implementation.
Why use it?
It prevents completed work and its approvals from being lost when requirements or research change. It also makes the new scope and decisions visible to the team.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

sw-pivot 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.

Specwright Pivot

Goal

Research-backed rebaselining for the selected work. Capture preserved scope, understand what changed, classify the pivot, revise the affected open work via architect, and hand back to /sw-plan or /sw-build as appropriate. Applies protocols/decision.md for all decisions. Revisions auto-applied and recorded in decisions.md; the revised artifact set is the contract.

Inputs

  • {worktreeStateRoot}/session.json — selected work for this worktree
  • {repoStateRoot}/work/{selectedWork.id}/workflow.json — selected work state, active unit, tasksCompleted, tasksTotal, and work/unit paths
  • work-level artifacts: design.md, context.md, assumptions.md, decisions.md, integration-criteria.md when present
  • active or affected unit artifacts: spec.md, plan.md, context.md
  • {workArtifactsRoot}/{selectedWork.id}/approvals.md — durable approval ledger for design and unit lineage
  • Pivot reason (argument or conversation)
  • Optional recent retro or research inputs when available and relevant

Outputs

  • revised work-level artifacts when design or scope changes require them
  • regenerated affected remaining-unit artifacts when unit boundaries or observable behavior change
  • updated integration-criteria.md when structural pivots stale the current criteria
  • selected work's workflow.json — pivot classification, active state, and affected remaining work updated
  • decisions.md — pivot decisions recorded

Constraints

Pre-condition (LOW freedom): Resolve the selected work from the current worktree session. Valid entry states are planning, building, and verifying. Reject designing, shipping, and shipped with explicit guidance: use /sw-design change request flow for designing, and start a fresh work or normal ship/fix flow for shipping or shipped. If another live top-level worktree owns the selected work, STOP with explicit adopt/takeover guidance.

Snapshot (LOW freedom): Read the selected work's completed and open scope. Present preserved baseline scope versus delta scope before proposing any mutation.

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.
