haiku-change-mode

haiku-change-mode is a skill for Claude Code from gigsmart/haiku-method. It costs 30 tokens per session (529 once invoked), scanned A, original, Apache-2.0.

A workflow for changing how much human involvement an active H·AI·K·U task requires while it is running.

In plain words
What is it for?
Use it to change the execution mode of an in-progress intent. It can infer the intent from the current branch or ask you to choose one, subject to restrictions after work has started.
Why use it?
It helps when the original mode no longer fits the task, such as when a change needs more review or can safely use more automation.

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

haiku-change-mode 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 9d 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 — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Change Mode

Change the execution mode of an in-flight intent. Use when:

  • The mode chosen at start no longer fits (e.g. discrete is too heavy for a small change, or continuous is too autonomous for high-risk work).
  • A teammate picked up an intent and wants different review semantics than the original owner.
  • An intent was created with the wrong mode and you need to correct it before too much state accumulates.

Process

  1. Resolve the intent. If no slug is in scope (current branch isn't a haiku/<slug>/... branch), ask which intent to change. Otherwise infer from the branch.

  2. Call haiku_select_mode with the intent slug. The tool elicits a mode value from the user. It will automatically:

    • Hide quick from the picker if the intent has already started a stage (you cannot enter or leave quick mid-flight — it's single-stage by definition).
    • Hide all options except the current mode if the intent is in quick and has started (no transition out is allowed).
    • For non-quick destinations: write mode to intent.md and set stages to the studio's full stage list (idempotent — restoring the full list is safe even if it was already there).
  3. Drive forward. After the mode is picked, call haiku_run_next { intent: "<slug>" }. The workflow engine continues from wherever the intent currently is — mode changes don't reset stage progress.

Constraints

  • No quick transitions mid-flight. Quick mode is single-stage and chosen at intent creation only. Switching into quick would amputate the rest of the workflow; switching out would suddenly add stages the user never reviewed. The engine refuses both.
  • Cannot change mode pre-studio. If studio isn't set yet, the intent hasn't reached mode selection — use /haiku:haiku-start to drive the initial elicitation chain instead of this skill.

Notes

  • This skill never accepts a free-form mode value as an argument. Mode is engine-managed; the only way to set it is through haiku_select_mode's elicitation.
  • discrete-hybrid is a derived mode, not directly selectable. The engine computes it from continuous + per-stage external gates.

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.

haiku-change-mode is a skill published in the GitHub repository gigsmart/haiku-method (24 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 529 once invoked, about $0.0002 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 2026-08-30.
