Decider
Manages Architecture Decision Records (ADRs) — represented in this skill as numbered DXXX architectural decision documents indexed in INDEX.md (by default under docs/decisions/) — with canonical templates, creation/update workflows, and a search CLI. Provides the single source of truth for decision entry format and lifecycle.

Commands
| Command |
Purpose |
Output |
search --issue [ID] |
Find decisions linked to an issue |
JSON [{id, decision, path}] |
search "[KEYWORDS]" |
Ranked keyword search (AND, scored) |
JSON [{id, decision, path, score}] |
search "a|b" |
Regex OR search |
JSON [{id, decision, path}] |
list |
List all active decisions |
JSON [{id, decision, path}] |
next-id |
Get next available DXXX |
Single DXXX line |
get [DXXX] |
Get decision details |
JSON {id, decision, status, date, path} |
Options: --limit N (default: 5) for search results.
Workflows
| Workflow |
Trigger |
Purpose |
workflows/create-decision.md |
Research complete, significant path choice |
Assign ID, write file, add INDEX row, update superseded |
workflows/update-decision.md |
New decision affects existing |
Supersede, partial supersede, or revisit existing entries |
workflows/search-decisions.md |
Before implementing, reviewing, auditing |
Search by issue, keywords, or ID |
Templates
| Template |
Purpose |
templates/decision-entry.md |
Decision file format (minimal, standard, comprehensive) |
templates/index-row.md |
INDEX.md table row format |
Schemas
| Schema |
Purpose |
schemas/decision-format.md |
Canonical format constraints for decision documents and INDEX |
Project-level configuration:
| Variable |
Purpose |
Default |
$DECISIONS_DIR |
Path to decision documents directory |
Auto-discovers docs/decisions/, decisions/, doc/decisions/, or adr/ with INDEX.md |
Set DECISIONS_DIR in committed vstack.settings.toml under [env] when it is shared project policy. .env.local remains supported for local overrides.
If the decisions directory does not exist (never initialized), read-only lookups (search, list) emit an empty JSON array with a stderr note and exit 0 — no decisions recorded is not an error. next-id and get still require an initialized directory, and a configured path that exists but is not a directory is always a hard error.

Quick Reference
Creating Decisions
- Get next ID:
decisions next-id
- Select template size (minimal/standard/comprehensive) from
templates/decision-entry.md
- Write decision file to
[project decision documents]/[DECISION_ID]-[DESCRIPTOR].md
- Add row to
[project decision documents]/INDEX.md
- Update any partially superseded decisions
Searching Decisions
- By issue:
decisions search --issue [ISSUE_ID]
- By keywords:
decisions search "[RELEVANT_KEYWORDS]"
- Read full decision files — index summaries are insufficient for understanding scope and rejected alternatives
- Suggestions contradicting active decisions are invalid unless decision is flawed
Decision Entry Format
All entries require: title (# DXXX: Title), date, status, research ref (or —), decision statement, rationale, revisit conditions. See schemas/decision-format.md for full constraints.
Decision Approval
Do not create decision documents without explicit user approval. If your work involves a significant architectural choice, technology selection, or trade-off that warrants a decision record, surface this in your response upon task completion — e.g., "This introduced a decision worth recording: [brief summary]. Want me to create a decision entry?" Let the user confirm before running the create workflow.
Content Guidelines
What to Log
- Technology selections with alternatives considered
- Performance trade-offs (chose X over Y for reason Z)
- Significant path choices where conditions might change
- Research-informed decisions
What NOT to Log
- Variable names, small refactors, bug fixes
- Obvious choices with no realistic alternatives
- Standard pattern applications
