Harness Progress Tracker

Phase 65.4 (Progress Tracker) — 3rd surface of the cognitive-load HTML triplet. Following Plan Brief / Acceptance Demo, this is the third HTML surface, allowing you to see the full picture of the session in progress at a glance on a single page.

Quick Reference

Mission

Generate a single HTML page that allows a non-engineer vibecoder to understand in 3 seconds in a browser how many tasks have been completed in the current session, how far along they are, when they are expected to finish, and what has been spent so far.

Does:

• Count cc:TODO / cc:WIP / cc:done tasks from Plans.md
• Calculate progress_pct (completion percentage) (cc:done / total tasks * 100)
• Display elapsed minutes / estimated total minutes / cost so far / cost estimate
• Display drift alerts (populated from Phase 65.4.3 onward)

Does NOT (this cycle):

• Live update via WebSocket / SSE (static HTML, updated by regeneration)
• Historical comparison with past sessions (separate axis in Phase 65.4.4)
• Cross-project view for other projects (independent from Phase 65.3)

Schema: progress-snapshot.v1

Full spec: schemas/progress-snapshot.v1.schema.json

schema:        progress-snapshot.v1
project:       <basename of git repo>
current_task:  <first cc:WIP item one-line summary; empty string if none>
progress_pct:  <integer 0-100, cc:done / total tasks * 100 rounded>
todo_tasks:    [{number, title}]    <- cc:TODO only
wip_tasks:     [{number, title}]    <- cc:WIP only
done_tasks:    [{number, title, commit}]   <- cc:done [hash] only, hash is 7 characters
elapsed_minutes:          <int, from state file>

Execution Flow

Step 0: Get PROJECT_NAME

PROJECT_NAME="$(basename "$(git rev-parse --show-toplevel)" 2>/dev/null || echo "current")"

Step 1: Build the snapshot

SNAPSHOT_JSON="$(mktemp /tmp/progress-snapshot-XXXX.json)"
bash scripts/progress-snapshot.sh \
  --plans Plans.md \
  --project "$PROJECT_NAME" \
  > "$SNAPSHOT_JSON"

scripts/progress-snapshot.sh (implemented in Phase 65.4.1) parses Plans.md and outputs JSON conforming to the progress-snapshot.v1 schema.

Step 2: Render HTML

OUT_PATH="${OUT_PATH:-out/progress-snapshot.html}"
mkdir -p "$(dirname "$OUT_PATH")"

bash scripts/render-html.sh \
  --template progress \
  --data "$SNAPSHOT_JSON" \
  --out "$OUT_PATH"

Step 3: Open in browser

Only when the --no-open flag is absent (skipped for background regeneration from PostToolUse hook):

bash scripts/plan-brief-open.sh --path "$OUT_PATH"

Cross-project search (default OFF)

The --cross-project-group <name> flag will be added in Phase 65.4.4. In this cycle (65.4.1), it is default OFF; aggregation is for the current project only.
