Friction Retrospective

Purpose / When to Activate

Activate to aggregate and analyze friction captured during delivery. This skill reads ## Friction Log sections from delivery artefacts and detects patterns that warrant promotion to durable memory (conventions, decisions, rule updates).

Recommended triggers (conventions, not rules):

  • Per-Epic: when an Epic is marked done
  • Monthly: alongside memory-refresh
  • Incident: if a single Story generates 3+ friction events

Constraint: Only the Discovery Agent may invoke this skill. Delivery agents capture friction; Discovery analyzes it.

Process

  1. Scope resolution — determine which artefacts to scan:

    • If epic filter: scan artefacts matching {epic_id}S*
    • If date_range filter: scan artefacts within date range (from frontmatter created_at)
    • If type filter: scan all artefacts but only extract entries matching the specified friction type
    • If no filter: scan all artefacts (full retrospective)

  2. Friction extraction — for each artefact containing a ## Friction Log:

    • Parse the table rows
    • Tag each entry with: Story ID (from filename), date (from frontmatter), artefact type (impl-report / qa-report / micro-delivery-report)

  3. Pattern detection — analyze extracted entries:

    • Group by type (ac-ambiguity, missing-context, tool-failure, etc.)
    • Count frequency per type
    • Identify thematic clusters within each type (e.g., multiple missing-context about the same domain)
    • Flag all entries with signal: high
    • Flag types with frequency ≥ 3

  4. Classify promotion candidates — for entries meeting promotion threshold:

    • signal: high → automatic promotion candidate (CAND-XXX)
    • frequency ≥ 3 for same type+theme → promotion candidate
    • Map each candidate to its promotion target (see Promotion Path below)

  5. Produce the report — structured in 4 sections:

    • Pattern Summary: type distribution, top themes, overall friction density
    • High-Signal Events (CAND-XXX): each candidate with evidence, proposed promotion target, and recommended action
    • Low-Signal Events: grouped by type, listed for awareness
    • Retrospective Notes: observations, cross-cutting themes, questions for human review

  6. Write or return — if scope is named (epic or date range), write to contexts/artefacts/retrospectives/{scope}.retro.md; otherwise return inline

Important: This skill identifies candidates and recommends actions. Actual promotion to memory is performed by the Discovery Agent using memory-ingest — never automatically by this skill.

Outputs

  • Retrospective report with pattern analysis
  • Promotion candidates (CAND-XXX) with evidence and recommended targets
  • Friction density metrics (events per Story, per type)

Quality Checks

  • Every CAND-XXX has at least 2 supporting evidence entries (or 1 with signal: high)
  • Promotion targets are specific (file path + section), not vague
  • Low-signal events are listed but never promoted
  • Report does not contain implementation fixes — only identifies what to fix and where

Non-Goals

This skill must NOT:

  • Write to memory directly (it produces candidates; Discovery promotes)
  • Modify rules, conventions, or decisions
  • Re-run or remediate delivery — it is purely analytical
  • Assign blame to agents or sub-agents
