change

A workflow guide for changing requirements during an active Draft development track. It assesses the effect on finished and remaining work before proposing updates to the specification and plan.

In plain words
What is it for?
Reviewing and applying mid-project changes to a Draft track after showing the proposed impact and getting confirmation.
Why use it?
It helps prevent requirement changes from silently invalidating completed work or leaving the plan inconsistent.

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

change 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 2d 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.

Course Correction

You are handling a mid-track requirement change using Draft's Context-Driven Development methodology.

Red Flags - STOP if you're

  • Applying changes to spec.md or plan.md without showing the user what will change first
  • Invalidating [x] completed tasks without flagging them explicitly
  • Proceeding past the CHECKPOINT without user confirmation
  • Editing files when the user said "no" or "edit"

Show impact before applying. Always confirm.


Step 0: Verify Draft Context

ls draft/tracks.md 2>/dev/null

If draft/ does not exist: STOP — "No Draft context found. Run /draft:init first."


Step 1: Parse Arguments

Extract from $ARGUMENTS:

  • Change description — free text describing what needs to change (required)
  • Track specifier — optional track <id> prefix to target a specific track

Default Behavior

If no track <id> specified:

  • Auto-detect the active [~] In Progress track from draft/tracks.md
  • If no [~] track, find the first [ ] Pending track
  • Display: Auto-detected track: <id> - <name> before proceeding

If no change description provided:

  • Error: "Usage: /draft:change <description> or /draft:change track <id> <description>"

Step 2: Load Context

  1. Read draft/tracks/<id>/spec.md — extract requirements and acceptance criteria
  2. Read draft/tracks/<id>/plan.md — extract all tasks with their current status ([ ], [~], [x], [!])
  3. Read draft/tracks/<id>/metadata.json — for track type and status
  4. Read draft/tracks/<id>/hld.md if present — extract Architecture, Detailed Design components, Dependencies, Checklist sections, and Approvals table (signed/unsigned)
  5. Read draft/tracks/<id>/lld.md if present — extract Classes/Interfaces, Data Model, Algorithms, Error Handling sections

Step 3: Analyze Spec / HLD / LLD Impact

Analyze the change description against the loaded spec, HLD, and LLD.

Code-grounded impact (Ground-Truth Discipline G1, G2, G4): Classification ("Modified", "Unaffected", etc.) must be informed by the current code, not just the prior spec text. For each requirement / AC you're about to mark Unaffected, confirm the code path it depends on still behaves as the spec claims — Read the cited file or a representative file in the affected module before stamping Unaffected. Specs and implementations drift; "spec text unchanged" ≠ "behavior unchanged."

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.

change is a skill published in the GitHub repository drafthq/draft (40 stars, last pushed 13d ago), licensed MIT. It adds 29 tokens to every session and 2,357 once invoked, about $0.0001 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.
