Impact Efficiency Report - 2026-06-16

## Executive Summary

Over the 180-day window (2025-12-18 to 2026-06-16), 3 of 7 qualifying PR outcomes were accepted, delivering **205 total objective value**. The highest-impact work was two **bug** fixes ([PR #37863](https://github.com/github/gh-aw/pull/37863), [PR #37565](https://github.com/github/gh-aw/pull/37565)) resolving critical safe-outputs and multi-repo checkout failures, contributing 170 of 205 value. All accepted outcomes are attributed to **PR Description Updater** (0.32 value/AIC). Repository-wide Impact Efficiency is **0.005** — 43,055 AIC was spent mostly on analytics/reporting workflows with no linked-issue PR outcomes; 993 of 1,000 sampled PRs were excluded for lacking `Closes #N`.

## Agentic Work by Objective

### bug (value: 85) — Highest-impact

| Accepted | Total Value | AIC (approx.) | Efficiency (approx.) |
|---:|---:|---:|---:|
| 2 | 170 | ~181 | ~0.94 |

- [PR #37863](https://github.com/github/gh-aw/pull/37863) -> [#37835](https://github.com/github/gh-aw/issues/37835): Fix push_to_pull_request_branch branch derivation
- [PR #37565](https://github.com/github/gh-aw/pull/37565) -> [#37545](https://github.com/github/gh-aw/issues/37545): Fix multi-repo checkout when Configure Git credentials clobbers origin

### improvement (value: 35)

| Accepted | Total Value | AIC (approx.) | Efficiency (approx.) |
|---:|---:|---:|---:|
| 1 | 35 | ~90 | ~0.39 |

- [PR #38185](https://github.com/github/gh-aw/pull/38185) -> [#38143](https://github.com/github/gh-aw/issues/38143): Add execcommandwithoutcontext Go linter analyzer

**Highest AIC category (no value):** Analytics/reporting stack consumed ~18,502 AIC (43% of total) — daily-experiment-report (3,625), Impact Efficiency Report (2,647), Contribution Check (2,278), Daily Semgrep Scan (2,209), Daily Firewall Logs (2,144) — with zero linked-issue PR outcomes.

## Which Workflows Drove That Impact

### PR Description Updater — Most value (100% share)

| Outcomes | Value | AIC | Efficiency |
|---:|---:|---:|---:|
| 3 accepted | 205 | 633.26 | 0.32 |

Top categories: bug (170), improvement (35). Attribution based on `gh-aw-agentic-workflow` body metadata; creating workflow may differ (workflow-logs.json is empty).

### Daily Documentation Healer — 0 value

3 analyzed outcomes (all rejected): PRs [#36767](https://github.com/github/gh-aw/pull/36767), [#36371](https://github.com/github/gh-aw/pull/36371), [#35330](https://github.com/github/gh-aw/pull/35330). AIC: **unknown** (not in aic-by-workflow.json).

### Daily Documentation Updater — 0 value

1 analyzed outcome (rejected): [PR #35906](https://github.com/github/gh-aw/pull/35906). AIC: 323.05.

### Top AIC consumers with zero attributed outcomes

## Unmapped Outcomes

None. All 7 outcomes mapped via objective-mapping.json. Labels `cookie`, `deep-report`, `linting`, `go`, `go-linters`, `closed:unknown` are absent from the mapping and ignored.

---

## Interpretation

- **Impact Efficiency (0.005)** vs **accepted count (3)**: count alone hides importance. Bug fixes (85 pts each) are ~2.4x more valuable than the linter improvement (35 pts).
- **Bug category** is most cost-efficient (~0.94 value/AIC) — highest-value, lowest estimated cost.
- **PR Description Updater** is the only workflow with attributed delivered value (0.32 efficiency). Attribution caveat: it is a description-update workflow; the underlying code authors may be different.
- **Daily Documentation Healer**: 3 closed-without-merge documentation PRs suggest a systematic acceptance issue. AIC unknown.
- **Top 8 AIC workflows (43%)** have zero linked-issue outcomes; value likely delivered through reports and non-PR channels not covered by this metric.

## Data Quality

| Gap | Notes |
|---|---|
| PR linked-issue coverage | 99.3% excluded (993/1000). Leading metric gap. |
| Safe-output outcomes | evaluations.jsonl is empty; 0 outcomes. |
| Workflow attribution | workflow-logs.json is empty; attribution from body markers only. Merged PR creating workflows unknown. |
| Daily Doc Healer AIC | Not in aic-by-workflow.json; impact efficiency not computable. |
| Per-category AIC | Approximated: 633.26 total / 7 runs = ~90.5 AIC/run for PR Description Updater. |

**AIC source**: Deterministic — aic-by-workflow.json (48 snapshots, token-audit-memory). Total: 43,055.27. No live fallback used.

---

## Human Work

369 merged PRs identified as potentially human-authored (no `gh-aw-agentic-workflow` body marker). All 3 PRs with linked issues had agentic markers, so zero human PRs are traceable to objectives.

| Metric | Value |
|---|---:|
| Potentially human-authored merged PRs | 369 |
| With linked closing issue | 0 |
| Mapped to objective | 0 |

No AIC computed for human work. Caveat: empty workflow-logs.json means human/agentic distinction relies solely on body markers and may inflate the human count.
