dx-estimate

name: dx-estimate description: Analyze an Azure DevOps/Jira User Story and produce a structured estimation — understanding, implementation plan, recommended hours/SP, AEM pages affected, and open questions. Posts result as an ADO/Jira comment. Batch mode: space-separated IDs for parallel estimation. Use when you want an AI-generated estimation for a story. when_to_use: "Use when estimating story effort. Trigger on 'estimate this', 'how many hours for this story', 'story points', 'AI estimate', or when given a User Story ID and asked to provide an effort estimate." argument-hint: "<Work Item ID(s) — space-separated for batch>" disable-model-invocation: true allowed-tools: ["read", "edit", "search", "write", "agent", "ado/", "atlassian/"]

Defaults

Read shared/provider-config.md for provider detection and tool mapping.

Read .ai/config.yaml:

• tracker.provider (or scm.provider for backward compat) — ado (default) or jira

If provider = ado:

• Organization: scm.org
• Project: scm.project

If provider = jira:

• Jira URL: jira.url
• Project Key: jira.project-key

You are a coordinator. You do NOT implement anything yourself. You delegate each analysis step to a subagent via the Agent tool, then synthesize results and post an estimation comment.

Argument

The argument is one or more ADO work item IDs — numeric values (e.g., 2435084) or Jira issue keys, space-separated for batch mode.

If the user provides a full ADO URL like https://dev.azure.com/{org}/{project}/_workitems/edit/{id}, extract the numeric ID.

If no argument is provided, ask the user for the work item ID(s).

Parse the argument: split on whitespace to produce a list of IDs.

Single or batch?

• If 1 ID: continue to "Execution Order" below
• If 2+ IDs: continue to "Batch Mode"

Batch Mode

For each ID, use the Agent tool to dispatch a subagent with prompt: Run /dx-estimate <id>

Run all agents in parallel. Each subagent runs the full estimation flow independently (fetch → explain → research → synthesize → post ADO comment). Each produces its own spec files and ADO comment — identical output to running /dx-estimate <id> individually.

After all agents complete, print a summary table:

## Batch Estimation Summary

| ID | Title | BE | FE | Auth | Total | SP | Questions | Status |
|----|-------|----|----|------|-------|----|-----------|--------|
| <id> | <title> | Xh | Xh | Xh | Xh | X | X | Posted |
| ... | ... | ... | ... | ... | ... | ... | ... | ... |

Then STOP — do not continue to the single-ticket flow below.

Execution Order

Step 1: fetch     → raw-story.md
Step 2: explain   → explain.md
Step 3: research  → research.md
Step 4: synthesize estimation + post ADO comment

Idempotent by default: Steps 1-3 check if output files already exist and are still valid before regenerating. Step 4 checks for an existing estimation comment (by signature) and updates it instead of duplicating.

Instructions

1. Dispatch steps 1–3 sequentially

For each step, use the Skill tool to invoke the skill in a fork. Wait for each to return before starting the next.

Step 1 — Fetch:

Invoke /dx-req <id> (Phase 1 only — fetch)

Print: Step 1/4 done — followed by the summary.

Step 2 — Explain:

Invoke /dx-req <id> (Phase 3 only — explain)

Print: Step 2/4 done — followed by the summary.

Step 3 — Research:

Invoke /dx-req <id> (Phase 4 only — research)

Print: Step 3/4 done — followed by the summary.

2. Synthesize estimation (step 4)

Find the spec directory (.ai/specs/<id>-*/). Read:

• raw-story.md — original story content, title, acceptance criteria
• explain.md — distilled requirements, areas of change, repos required
• research.md — files to modify, existing components, cross-repo scope

From these, build the estimation:

2a. Understanding

Write 2-3 sentences describing what needs to be done in plain language. Mention which layers are affected (backend, frontend, authoring, cross-repo).

2b. Implementation Plan

Write a short bullet list of concrete changes needed. Group by layer:

• Backend — models, exporters, services, OSGi config
• Frontend — JS components, SCSS, HBS templates
• Authoring — dialog fields, content policies, page templates
• Cross-repo — if research.md indicates cross-repo scope

Each bullet should be 1 line: <Layer> — <what changes>.

2c. AEM Pages Affected

If research.md or explain.md mentions specific AEM components being modified:

1. Search the codebase for the component name to identify it
2. Use the aem-component skill pattern — search .ai/project/component-index-project.md or .ai/project/component-index.md for the component name to find which pages use it
3. List the pages (max 10). If more than 10, say "X+ pages — broad impact"

If no component changes are identified, write: "N/A — no component changes identified"

2d. Estimation Heuristics

Apply these guidelines to estimate hours per group. These are guidelines, not rigid formulas — use judgment based on the specific requirements:

Adjustments:

• Cross-repo scope: +30% overhead (coordination, separate PRs, deployment order)
• Authoring changes: +4h base (dialog updates, content migration, author testing)
• Existing similar component to copy from: -20% (pattern is established)
• Unclear/ambiguous requirements: +20% risk buffer

Break down hours by group:

• Backend (BE): Sling Models, exporters, services, OSGi config
• Frontend (FE): JS component, SCSS, HBS template, icons
• Authoring: Dialog XML, content policies, page template, content updates

Total SP = round to nearest Fibonacci (1, 2, 3, 5, 8, 13, 21).

2e. Open Questions

List specific ambiguities from explain.md and research.md that could change the estimate:

• Missing design specs or Figma links
• Unclear acceptance criteria
• Dependency on backend API not yet available
• Multi-market scope unclear (which markets need this?)

3. Post ADO Comment

Read .ai/config.yaml to get the ADO project name (ado.project or scm.ado-project).

Check for existing estimation comment:

Use mcp__ado__wit_list_work_item_comments to list existing comments on the work item. Search for one containing the signature <!-- ai:role:estimation-agent -->.

If provider = jira

Comments are included in the jira_get_issue response. Fetch the issue and search fields.comment.comments[].body for <!-- ai:role:estimation-agent -->:

mcp__atlassian__jira_get_issue
  issue_key: "<issue key>"

• If found: use mcp__ado__wit_update_work_item_comment (or post a new comment — whichever the MCP supports) to update it. For Jira, use mcp__atlassian__jira_edit_comment if updating.
• If not found: post a new comment

Dry run check: If the user's prompt includes "dry run" (case-insensitive), print the estimation to stdout and do NOT post to ADO. Print: (Dry run — estimation not posted to ADO)

**Suggested SP:** <X> (~<Y>h total)
**Directory:** `.ai/specs/<id>-<slug>/`

| Group | Hours |
|-------|-------|
| Backend | Xh |
| Frontend | Xh |
| Authoring | Xh |

**Open questions:** <count>
**AEM pages affected:** <count or N/A>

### Next Steps
1. Review estimation comment on the ADO work item
2. Discuss open questions with BA/PO
3. Set Story Points on the work item
4. `/dx-req-tasks <id>` — break down into child tasks with hour estimates

5. Log Run

After the final summary, log this run for project learning.

5a. Ensure directory:

mkdir -p .ai/learning/raw

5b. Append run record:

Append one JSONL line to .ai/learning/raw/runs.jsonl:

{"timestamp":"<ISO-8601>","ticket":"<id>","flow":"estimation","steps":{"raw-story":"<created|updated|skipped>","explain":"<created|updated|skipped>","research":"<created|updated|skipped>","estimation":"posted"},"failed":false}

Use Bash to append — echo '<json>' >> .ai/learning/raw/runs.jsonl

Examples

1. /dx-estimate 2416553 — Fetches the story, distills requirements, researches the codebase, then synthesizes an estimation: BE 16h + FE 12h + Authoring 4h = 32h total, suggested SP: 8 (Fibonacci). Posts the estimation as an ADO comment with the <!-- ai:role:estimation-agent --> signature.

2. /dx-estimate 2416553 2416554 2416555 — Batch mode. Spawns parallel subagents, each running the full estimation flow. Each story gets its own spec files, ADO comment, and estimation. Prints a summary table at the end.

3. /dx-estimate 2416553 dry run — Runs the same analysis but prints the estimation to stdout without posting to ADO. Useful for reviewing the estimate before committing it to the work item.

4. /dx-estimate 2435084 (re-run) — Finds existing spec files (raw-story.md, explain.md, research.md) from a previous run, skips regeneration, and updates the existing estimation comment (detected by signature) instead of creating a duplicate.

Troubleshooting

• Estimation seems too high or too low Cause: The heuristics are guidelines, not exact formulas. Complex cross-repo stories or simple config changes can skew estimates. Fix: The estimate is advisory. Discuss open questions with the team and adjust Story Points based on team velocity and domain knowledge.

• ADO comment posting fails Cause: ADO PAT lacks "Work Items: Read & Write" permission, or the work item is in a closed state that doesn't accept comments. Fix: The skill prints the estimation to stdout so you can copy-paste it manually. Check PAT permissions and work item state.

• "No spec files found" after research step Cause: The fetch or explain step failed silently, leaving the spec directory empty. Fix: Check the step-by-step output for error messages. Run /dx-req <id> manually to diagnose.

Error Handling

If any agent returns FAIL:

1. Print the failure with the agent's error message
2. Retry the failed step once with the same agent
3. If still failing:
   • Print which step failed and the error
   • Print which steps succeeded and their outputs
   • Suggest running the individual skill manually: "Run /dx-<skill> to retry this step"
   • Do NOT continue past a failed step if subsequent steps depend on its output (steps 1→2→3→4 are strictly sequential)

If the ADO comment posting fails:

• Print the estimation to stdout so the user can copy-paste it manually
• Print: Failed to post comment to ADO. Copy the estimation above and paste it manually.

Rules

• You are coordinator only — all analysis happens inside the agent's isolated context (steps 1-3)
• Never implement steps yourself — always delegate via Agent tool for steps 1-3
• Step 4 (synthesis) is yours — you read the spec files and build the estimation
• Sequential dependencies are strict — never dispatch step N+1 until step N returns OK
• Keep main context lean — you only see compact summaries from steps 1-3, not file contents (until step 4)
• Progress reporting — print status after each step so the user can see progress
• Same quality as individual skills — running /dx-estimate reuses the same fetch/explain/research output as running each skill separately
• Advisory only — estimation is a recommendation, not a commitment. Always include the disclaimer.
