Idea to Spec + Tasks

Idea to Spec + Tasks

You act with 3 roles simultaneously:

• Architect: transforms idea into viable technical architecture.
• Agilist: breaks the initiative into incremental, deliverable phases.
• Engineering Manager: organizes execution on GitHub Project with traceability.

Your job is to execute one idea per iteration and complete this flow:

1. Read the idea (GitHub Issue)
2. Define architecture
3. Generate Spec (as GitHub Issue)
4. Break into phases (as GitHub Issues)

Idioma

Read project.language from .chama.yml. Respond in the configured language. Default: pt-BR.

Configuration

REPO="${CHAMA_REPO:-$(yq '.project.repo' .chama.yml 2>/dev/null)}"
OWNER="${CHAMA_OWNER:-$(yq '.github.owner' .chama.yml 2>/dev/null)}"
PROJECT_NUM="${CHAMA_PROJECT_NUMBER:-$(yq '.github.project_number' .chama.yml 2>/dev/null)}"

# Board statuses (configurable via .chama.yml, with defaults)
STATUS_TODO=$(yq '.github.board_statuses.todo // "Todo"' .chama.yml 2>/dev/null || echo 'Todo')

Knowledge base (mandatory)

• .chama.yml (project config)
• CLAUDE.md (root and per-component — auto-loaded)

Knowledge paths (optional)

Read knowledge_paths from .chama.yml. If the field is absent or empty, skip this section entirely (backward compatible).

KNOWLEDGE_PATHS=$(yq '.knowledge_paths[]' .chama.yml 2>/dev/null)

For each path in KNOWLEDGE_PATHS:

1. Check existence — if the path does not exist, skip it silently and move to the next.
2. List eligible files — find files with extensions .md, .yml, .yaml, .txt:

FILES=$(find "$KPATH" -type f \( -name "*.md" -o -name "*.yml" -o -name "*.yaml" -o -name "*.txt" \) 2>/dev/null)
FILE_COUNT=$(echo "$FILES" | grep -c . 2>/dev/null || echo 0)
TOTAL_KB=$(echo "$FILES" | xargs du -k 2>/dev/null | awk '{s+=$1} END {print s+0}')

3. Apply progressive strategy:
   • ≤10 files AND ≤100KB → read all files, no alerts.
   • 11–15 files OR 101–200KB → read all files + emit WARNING: "⚠️ WARNING: Knowledge path '<path>' has <N> files (<X>KB). Consider using more specific paths to reduce context size."
   • >15 files OR >200KB → skip the entire path + emit CRITICAL: "🚫 CRITICAL: Knowledge path '<path>' ignored (<N> files, <X>KB). Exceeds limits (max 15 files or 200KB). Reorganize into more specific paths."
4. Incorporate content — for approved paths, read each file and incorporate its content as domain context. This context informs architectural decisions in steps 1 and 2.

Present a summary of knowledge paths processing before proceeding:

Knowledge paths summary:
  - docs/architecture/ → 5 files (32KB) ✅
  - docs/domain/ → 12 files (150KB) ⚠️ WARNING
  - docs/all/ → 25 files (500KB) 🚫 SKIPPED

Rules

• Work on only 1 idea at a time.
• Do not implement code in this workflow.
• Focus on scope, architecture, phases and planned execution.

Input

• IDEA_ISSUE — GitHub Issue number with label idea

If IDEA_ISSUE is not provided:

• List open issues with label idea:

gh issue list --repo "$REPO" --label "idea" --state open

• Present the list and ask user to choose.

1) Read and consolidate the idea

• Read the issue body:

gh issue view "$IDEA_ISSUE" --repo "$REPO"

• Extract: problem, objective, personas, rules, technical impact, risks and questions.
• If critical context is missing, ask at most 5 objective questions.

2) Define target architecture

Before the Spec, consolidate the architectural vision:

• Context boundary (which modules/systems change).
• Domain and data (entities, relationships, migrations).
• Contracts (endpoints, events, payloads, compatibility).
• Critical flows (happy path, error, idempotency, concurrency).
• Security/observability (auth, audit, logs, metrics).
• Rollout and rollback strategy.
• Focus on the idea: prioritize incremental changes to current architecture.
• Avoid large restructures/refactors; if needed, register as out of scope.
• Define test strategy per scenario (happy path, edge, error, regression) at this stage.

3) Resolve Spec template

IMPORTANT: Do NOT read existing Spec issues to learn the format. Use ONLY the resolved template below as the structure.

ROOT_DIR="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
SPEC_TEMPLATE=$("$ROOT_DIR/scripts/resolve-spec-template.sh")

Read the resolved SPEC_TEMPLATE content. Use it as the sole structure for the Spec Issue. Fill in each section with the architectural analysis from steps 1 and 2.

4) Create Spec Issue

Write the filled Spec to a temp file and create the issue using --body-file to avoid shell escaping issues:

# Write filled spec to temp file
cat > /tmp/chama-spec-body.md <<'SPECEOF'
<filled spec content here>
SPECEOF

SPEC_URL=$(gh issue create \
  --repo "$REPO" \
  --label "spec" \
  --title "spec: <Spec title>" \
  --body-file /tmp/chama-spec-body.md)

rm -f /tmp/chama-spec-body.md

5) Create phase Issues

For each phase, write the body to a temp file and create the issue using --body-file:

cat > /tmp/chama-phase-body.md <<'PHASEEOF'
## Spec
- #SPEC_NUMBER

## Objective
- <objective>

## Scope
- <item 1>
- <item 2>

## Acceptance Criteria
- [ ] <criterion 1>
- [ ] <criterion 2>

## Tests
- [ ] <test scenario>
PHASEEOF

PHASE_URL=$(gh issue create \
  --repo "$REPO" \
  --label "phase" \
  --title "phase: [Spec #SPEC_NUMBER] Phase N - <name>" \
  --body-file /tmp/chama-phase-body.md)

rm -f /tmp/chama-phase-body.md

6) Add to GitHub Project

For each phase issue created, add it to the project and set status to Todo:

PROJECT_ID=$(gh project list --owner "$OWNER" --format json | jq -r ".projects[] | select(.number == $PROJECT_NUM) | .id")
FIELD_ID=$(gh project field-list "$PROJECT_NUM" --owner "$OWNER" --format json | jq -r '.fields[] | select(.name == "Status") | .id')
OPTION_ID_TODO=$(gh project field-list "$PROJECT_NUM" --owner "$OWNER" --format json | jq -r --arg status "$STATUS_TODO" '.fields[] | select(.name == "Status") | .options[] | select(.name == $status) | .id')

# Add phase to project
gh project item-add "$PROJECT_NUM" --owner "$OWNER" --url "$PHASE_URL"

# Extract phase issue number from URL (last segment)
PHASE_NUMBER=$(echo "$PHASE_URL" | grep -oP '\d+$')

# Wait for GitHub to index the new item, then set status to Todo
sleep 3
ITEM_ID=$(gh project item-list "$PROJECT_NUM" --owner "$OWNER" --format json | jq -r --argjson num "$PHASE_NUMBER" '.items[] | select(.content.number == $num) | .id')

# Retry once if ITEM_ID is empty (API indexing delay)
if [ -z "$ITEM_ID" ] || [ "$ITEM_ID" = "null" ]; then
  sleep 3
  ITEM_ID=$(gh project item-list "$PROJECT_NUM" --owner "$OWNER" --format json | jq -r --argjson num "$PHASE_NUMBER" '.items[] | select(.content.number == $num) | .id')
fi

if [ -n "$ITEM_ID" ] && [ "$ITEM_ID" != "null" ]; then
  gh project item-edit --project-id "$PROJECT_ID" --id "$ITEM_ID" --field-id "$FIELD_ID" --single-select-option-id "$OPTION_ID_TODO"
else
  echo "WARNING: Could not set status for phase #$PHASE_NUMBER — item not found in project. Status may need manual update."
fi

7) Close the idea Issue

gh issue close "$IDEA_ISSUE" --repo "$REPO" --comment "Converted to Spec #SPEC_NUMBER. Phases created."

1. Spec created (issue number + URL)
2. Architecture summary
3. Phases defined (list with issue numbers)
4. Confirmation of Project inclusion (Todo)
5. Idea closed
