Work Portfolio Analysis

Work Portfolio Analysis

This skill solves tasks that ask for a structured JSON readout from a shared work-item portfolio environment. The environment is reached over the network via environment_access.md; it exposes REST endpoints plus a restricted SQL passthrough. Three task families recur:

1. Portfolio mix — closed work, count-based category mix vs. a target mix.
2. SLA aging — primary SLA population, overdue items, aging, breach rate.
3. Release readiness — ship decision, milestone completion, gating items, blockers, dependency chains, readiness score.

Every task supplies input/payloads/answer_template.json. The template is authoritative for output shape (field names, required keys, enums, ordering). Two tasks that compute the same concept can name fields differently, so always emit values in the template's exact structure — do not carry field names over from one task to another.

How to run a task

1. Read the prompt. Extract scope parameters: scope_id, quarter, teams, product area(s), as-of date, recent-closed window, release id, etc. These vary per task — never hardcode them.
2. Read environment_access.md for the base URL, the X-Env-Token header value, and the allowed endpoint list. Reach the environment only through this file. See references/environment.md for the endpoint inventory, the SQL passthrough shape, and the full data model.
3. Fetch the data you need (REST list endpoints or POST /api/query with a SQL string). Prefer the SQL endpoint for filtered/aggregated reads.
4. Apply the record-handling and classification rules (see below and references/classification.md).
5. Compute per the task family in references/procedures.md.
6. Emit one JSON object matching the template exactly — no prose outside the JSON. Apply the ordering and precision rules in references/procedures.md.

Core record-handling rules (apply to every family)

The work_items table carries two stale trap fields that must be ignored, and one authoritative linkage field:

• mirror_status — STALE. Ignore. Use the authoritative status field.
• legacy_category — STALE. Ignore. Classify from work_type + labels + title per references/classification.md.
• duplicate_of — AUTHORITATIVE duplicate linkage. A record is a duplicate when duplicate_of is non-null or status == "Duplicate". A record is cancelled when status == "Cancelled".

Record roles:

• Primary = not a duplicate and not cancelled (duplicate_of is null AND status not in {Duplicate, Cancelled}). Only primary records are counted in totals, mixes, SLA populations, and milestone denominators.
• Duplicate = reported (grouped into clusters by the duplicate_of target) but never counted as primary work.
• Cancelled = excluded; reported in exclusion lists when the template asks.

Terminal / "complete" statuses (authoritative status): Closed, Done, Verified, Deployed. Non-terminal: In Progress, Review, Backlog, Reopened.

Portfolio category classification

Classify each primary item into exactly one of NewFeature, TechDebt, Reliability, Security. Gather signals from work_type, labels (array), and title (substring), then apply strict priority — first match wins:

Security > Reliability > TechDebt > NewFeature

Full signal sets and worked resolution rules are in references/classification.md. legacy_category is never used.

Ordering & precision (universal)

• ID lists: ascending / lexicographic, unless the prompt says otherwise.
• "Included work item" lists (portfolio mix): order by closed_at ascending, then id ascending.
• Teams: alphabetical (note any template that pins a specific order).
• Duplicate clusters: sorted by primary_id; each cluster's duplicate_ids sorted ascending.
• Percentages: 1 decimal place (percentage points).
• Rates and scores (breach_rate, sla_breach_rate, readiness_score): 3 decimal places.
• gap_pct = actual_pct − target_pct.

Output discipline

• Return a single JSON object matching answer_template.json exactly.
• No prose outside the JSON.
• Do not copy task-specific answer values from any example — recompute every value from the live environment for the current scope.
