Agent Progress Tracking Protocol

Overview

Every agent MUST write a progress status file at each step transition. This enables debugging stalled pipelines, understanding agent behavior, and resuming from failures.

File Location

.claude/specs/[feature]/agent-status/[agent-name].md

Example: .claude/specs/water-delivery/agent-status/product-manager.md

Create the agent-status/ directory if it doesn't exist.

When to Update

Write or update the status file at these moments:

1. Agent start — write initial file with all steps PENDING
2. Step transition — mark previous step COMPLETE, current step IN_PROGRESS
3. Step skip — mark as SKIPPED with reason
4. Error — mark as FAILED with error details
5. Agent complete — mark final step COMPLETE, set overall status to DONE
6. Agent blocked — mark current step as BLOCKED with blocker description

Status Values

Status	Meaning
PENDING	Not yet started
IN_PROGRESS	Currently executing
COMPLETE	Successfully finished
SKIPPED	Intentionally skipped (reason required)
FAILED	Error occurred (error details required)
BLOCKED	Waiting on external dependency
RETRYING	Failed once, retrying

File Format

# Agent Status — [agent-name]

## Summary
- **Agent:** [agent-name]
- **Phase:** [pipeline phase number]
- **Feature:** [feature-name]
- **Status:** IN_PROGRESS / DONE / FAILED / BLOCKED
- **Started:** [ISO timestamp]
- **Last Updated:** [ISO timestamp]
- **Duration:** [elapsed time]

## Steps
| # | Step ID | Name | Status | Started | Completed | Notes |
|---|---------|------|--------|---------|-----------|-------|
| 1 | read-context | Read project config | COMPLETE | 14:30:01 | 14:30:05 | Found NestJS + React stack |
| 2 | assess-requirements | Requirements clarity check | COMPLETE | 14:30:05 | 14:30:08 | Requirements are vague — full discovery needed |
| 3 | tier-1-discovery | Core questions (Tier 1) | IN_PROGRESS | 14:30:08 | — | Q3 of 6 asked |
| 4 | tier-2-discovery | Domain-adaptive questions | PENDING | — | — | |
| 5 | scope-discipline | MVP scope framing | PENDING | — | — | |
| 6 | write-prd | Write PRD (10 sections) | PENDING | — | — | |
| 7 | gap-analysis | Specification gap analysis | PENDING | — | — | |
| 8 | approval-gate | Request user approval | PENDING | — | — | |

## Sub-Step Detail
[For steps with internal progression, track granularity here]

### Step 3 — tier-1-discovery
| Sub-step | Status | Detail |
|----------|--------|--------|
| Q1 — Core purpose | COMPLETE | User described: "task management for remote teams" |
| Q2 — Target users | COMPLETE | B2B — team managers and employees |
| Q3 — Platforms | IN_PROGRESS | Waiting for user response |
| Q4 — Scope approach | PENDING | |
| Q5 — Core features | PENDING | |
| Q6 — Out of scope | PENDING | |

## Output Files
| File | Status | Detail |
|------|--------|--------|
| requirements.md | NOT_STARTED | |
| feature_list.json | NOT_STARTED | |

## Errors
[Log any errors encountered during execution]

| Timestamp | Step | Error | Recovery |
|-----------|------|-------|----------|
| — | — | — | — |

## Decision Log
[Record key decisions made during execution]

| Timestamp | Decision | Reasoning |
|-----------|----------|-----------|
| 14:30:08 | Full discovery needed | Requirements vague — no specific acceptance criteria provided |

Update Protocol

On Agent Start

1. Read your step table from the ## Progress Steps section in your agent definition
2. Create the status file with all steps set to PENDING
3. Set overall Status to IN_PROGRESS
4. Set Started timestamp

On Step Transition

1. Mark previous step as COMPLETE with Completed timestamp
2. Mark new step as IN_PROGRESS with Started timestamp
3. Update Last Updated timestamp
4. Add any Notes for completed step (brief: what was found/decided)

On Sub-Step Progress

For steps with internal iterations (e.g., asking multiple questions, processing multiple files):

1. Add a Sub-Step Detail section under ## Sub-Step Detail
2. Track each iteration with its own status
3. Update the parent step's Notes with progress count (e.g., "Q3 of 6 asked")

On Error

1. Mark current step as FAILED
2. Add entry to ## Errors table with timestamp, step, error description, and recovery action
3. If retrying, mark step as RETRYING
4. If unrecoverable, set overall Status to FAILED

On Skip

1. Mark step as SKIPPED
2. Add reason in Notes column (e.g., "SMALL task — skipped", "Already in project-config.md")

On Output File Creation

1. Update ## Output Files table when a file is written
2. Status values: NOT_STARTED, PARTIAL (with detail), COMPLETE
3. For partial writes, note which sections are done (e.g., "Sections 1-5 of 10")

On Key Decision

1. Add entry to ## Decision Log when making a non-trivial choice
2. Include reasoning so debugging can understand WHY a path was taken

On Agent Complete

1. Mark final step as COMPLETE
2. Set overall Status to DONE
3. Update Duration
4. Ensure all Output Files are marked COMPLETE or explain why not

Performance Rules

• Write frequency: Update the file at every step transition. For long steps with sub-steps, update at sub-step transitions too.
• Keep it brief: Notes should be 1 line. Don't write paragraphs.
• Timestamps: Use HH:MM:SS format (time only, not full ISO — saves space).
• Don't block on writes: If the Write tool fails, continue execution. Progress tracking should never block the actual work.
• Incremental updates: Use the Edit tool to update specific rows, not rewrite the entire file each time.

Reading Agent Status (for commands and debugging)

To check agent status:

Glob(".claude/specs/*/agent-status/*.md")
Read(".claude/specs/[feature]/agent-status/[agent-name].md")

To find stalled agents:

Grep("IN_PROGRESS", ".claude/specs/*/agent-status/", glob="*.md")

To find failures:

Grep("FAILED", ".claude/specs/*/agent-status/", glob="*.md")
