🦛 Hippo Memory Insights — 2026-04-23

[github-actions[bot]]

Summary

• Memories in store: 490 (440 episodic, 50 semantic)
• New lessons learned from commits today: 0 (1 duplicate skipped)
• Consolidation: 118 episodic merged, 50 new semantic memories created, 24 cross-layer duplicates removed
• Highest-confidence memory: stale .lock.yml files cause CI friction (score=1.007, retrieved 3×)

Top Memories Surfaced

1. mem_47a200206f0d [verified] — Recurring incident: stale workflow .lock.yml files cause churn and CI friction; run make recompile after markdown workflow edits. (retrieved 3×)
2. mem_6f57d3433efa [verified] — Recurring incident: Codex auth failures can break agent jobs; verify auth/mode/token setup before reruns. (retrieved 2×)
3. mem_ed00ab594cfa [verified] — Recurring incident: node: command not found on GPU/self-hosted paths when node runtime/tooling is missing; validate runtimes and PATH early. (retrieved 3×)
4. mem_bf872c93f014 [observed] — CI WILL FAIL if make fmt / pre-commit validation is skipped — this is automatic and non-negotiable. (retrieved 2×)
5. mem_afd5d7c7fbef [observed] — The validate-yaml job in .github/workflows/ci.yml scans all YAML files for ANSI escape sequences before other jobs run.
6. mem_004adbf3befe [observed] — Use distinct Go types (e.g. JobName, StepID) to prevent silent type-confusion bugs when mixing string identifiers.
7. mem_fc26e9553e72 [observed] — Workflow Health Monitoring runbook covers missing-tool errors, auth failures, MCP config issues, and safe-input/output problems.

Suggested Improvements

Error Patterns

• Stale .lock.yml files are the single highest-confidence recurring incident. Add a CI lint step or pre-commit hook that detects out-of-date lock files and fails early, rather than discovering it mid-run.
• node: command not found has been hit 3 times on self-hosted/GPU runners. Standardise on a copilot-setup-steps.yml that always installs Node 22 and verifies node --version before any workflow step that needs it.
• Codex auth failures (2× retrieved): document the required env vars and token scopes in a checklist that runs during agent job setup, rather than after a failure.

Code Quality

• Type safety (JobName, StepID, WorkflowID): the memory store has multiple entries about needing distinct Go types to prevent identifier mix-ups. Audit pkg/workflow/ for places that still use raw string for workflow/job/step identifiers.
• JavaScript CJS refactoring: skills/javascript-refactoring/SKILL.md is flagged — ensure .cjs split is complete and make lint-cjs passes cleanly.
• 7 low-quality memories flagged by hippo audit — run hippo audit --fix to prune junk and improve recall precision.

CI Health

• validate-yaml job catches ANSI escape sequences; the compiler (pkg/workflow/compiler_yaml.go) strips them automatically — confirm both sides are in sync to avoid false positives.
• make test is >5 min and marked "avoid locally" — consider caching test binaries or parallelising to keep the full-suite feedback loop under 3 min in CI.
• Pre-commit validation (make fmt) is explicitly marked non-negotiable. Consider adding a GitHub Actions push lint job that blocks PRs early if formatting is missed.

Quick Wins

1. Add make recompile to the PR checklist or a CI check to detect stale .lock.yml — this alone would eliminate the rejig docs #1 recurring CI incident.
2. Run hippo audit --fix to remove 7 low-quality memories and improve recall quality.
3. Pin Node 22 in copilot-setup-steps.yml for self-hosted runners to eliminate node: command not found failures.
4. Add a Codex auth pre-flight check — a 2-line script that validates the token before the agent job starts.
5. Embed all memories (hippo embed) — currently only 4/490 memories are embedded, which limits semantic search quality.

Longer-term Themes

• Stale generated files (.lock.yml, compiled JS): multiple memories point to the same root cause — generated artifacts that drift out of sync. A broader solution would be a CI job that re-runs all code-generation steps and fails if the working tree is dirty.
• Runner environment fragility: node not found, auth failures, and missing PATH entries all point to inconsistent runner environments. A standardised copilot-setup-steps.yml with smoke tests would address this class of problems systematically.
• Memory embedding coverage is 4/490 (< 1%) — this severely degrades semantic recall. Scheduling hippo embed as part of the daily runner would unlock much better memory retrieval quality.

Store Statistics

Metric	Value
Total memories	490
Episodic	440
Semantic	50
Pinned	0
At risk (< 0.2 strength)	0
Open conflicts	0
Avg strength	1.00

Action items for memory health:

• Run hippo audit --fix to remove 7 flagged low-quality entries
• Run hippo embed to increase embedding coverage from 4/490 → full store (required for better semantic recall)
• No stale or decayed memories — store is healthy
