GitReins Tier 2 “INCOMPLETE, `items: []`” — Agentic Evaluator Input-Token Cap Starvation

Class id: gitreins-tier2-incomplete-empty-bell-input-cap-starvation Area: gitreins task complete → Tier 2 (Agentic Evaluator) Severity: High (false “harness death” reports; task silently never judged) Fix cost: One config value, ~30 seconds Do NOT file a harness bug. This is evaluator context starvation, not a crash.

1. Symptom

gitreins task complete returns Tier 2 (Agentic Evaluator): INCOMPLETE, and the produced verdict.json has zero criteria results:

{
  "task_id": "...",
  "task_title": "...",
  "evaluated_at": "...",
  "passed": false,
  "summary": "...",
  "task_criteria": [...],
  "items": []
}

Key tell: top-level key set [evaluated_at, items, passed, summary, task_criteria, task_id, task_title] with items: []. This is the partial-or-INCOMPLETE return path, not a crash.

Other characteristics: - Deterministic on retry — same empty verdict, same ~2 min duration. - Evaluator model is healthy and reachable. - Evaluator starts, reads broadly across its iteration loop, exits before emitting any per-criterion items.

It looks like the harness killed the evaluator. It did not.

2. Root cause

The Tier 2 evaluator runs an agentic loop that reads many files to independently verify each criterion. Each iteration appends tool output to context; the engine enforces a hard input-token budget per evaluation.

Engine default cap: 4,000,000 input tokens (evaluator.max_input_tokens).
Trigger repos contain large generated tables — task-router/registry.json is 1.2 MB of JSON.
Reading that registry (plus schema, tests, prior iterations) exhausts the 4 M budget before a verdict is emitted.
The cap-exceeded path in engine/evaluator.py (~lines 1080–1270) returns partial-or-INCOMPLETE with summary beginning Cap exceeded: ... (or the LLM-call-failed variant).

The smoking gun is a logging.WARNING on stderr:

Eval cap exceeded: Input token budget (4.0M) exceeded (4.0M used).
Increase max_input_tokens or reduce message context.

Why it's invisible

The CLI sets logging to WARNING, so the line only appears on stderr. Piping (... 2>&1 | tail) drops/truncates it, leaving a blank INCOMPLETE that masquerades as harness death.

Not evaluator-harness-death (<project> DF class)

Signal	Cap starvation (this class)	Harness death
Upstream error	none	identical error (e.g. model-name resolution) in `promise`/`real-use`
Product contact	evaluator reads files	dies before contact
Stderr	`WARNING ... Eval cap exceeded ... Input token budget`	harness/model failure, no cap warning
Runtime	normal (~2 min)	early death
`verdict.json`	`items: []`, summary `Cap exceeded: ...`	no usable verdict / crash
Model health	healthy	unhealthy / misconfigured

Rule: cap-exceeded warning present ⇒ this class. Add headroom; do not file a harness bug.

3. Exact fix

Step 1 — Re-run with FULL stderr captured (never tail-pipe)

cd /path/to/repo
gitreins task complete 2>&1 | tee /tmp/gr-complete.log
# or:
gitreins task complete >/tmp/gr-complete.out 2>/tmp/gr-complete.err; echo "exit=$?"

Step 2 — Confirm the class

grep -n 'WARNING.*Eval cap exceeded.*Input token budget' /tmp/gr-complete.err /tmp/gr-complete.log

If absent, stop — it's a different class.

Step 3 — Raise the budget

Edit git-tracked .gitreins/config.yaml; bump evaluator.max_input_tokens 4000000 (4 M) → 12000000 (12 M). Engine default is 10 M; 12 M is safe for multi-MB tables.

yq (recommended):

cd /path/to/repo
yq -i '.evaluator.max_input_tokens = 12000000' .gitreins/config.yaml

Portable sed fallback:

cd /path/to/repo
grep -q '^\s*max_input_tokens:' .gitreins/config.yaml \
  && sed -i -E 's/^(\s*max_input_tokens:\s*).*/\112000000/' .gitreins/config.yaml \
  || printf '\nevaluator:\n  max_input_tokens: 12000000\n' >> .gitreins/config.yaml

Sanity check:

python -c "import yaml; c=yaml.safe_load(open('.gitreins/config.yaml')); print(c['evaluator']['max_input_tokens'])"
# -> 12000000

If headroom can't be raised, reduce evaluator context instead — exclude the giant generated file (e.g. add registry.json to evaluator ignore/glob exclusions). Raising headroom is the validated fix.

Step 4 — Commit (config is git-tracked)

cd /path/to/repo
git add .gitreins/config.yaml
git commit -m "chore(gitreins): raise evaluator max_input_tokens 4M -> 12M

Tier 2 agentic evaluator exhausted the 4M input budget on the 1.2MB
generated registry.json before emitting a verdict, producing
INCOMPLETE with items:[]. Bump headroom to 12M."
git push

Step 5 — Re-run

cd /path/to/repo
gitreins task complete 2>&1 | tee /tmp/gr-complete-after.log
grep -n 'Eval cap exceeded' /tmp/gr-complete-after.log || echo "OK: no cap warning"

The new verdict supersedes the old; both remain under .gitreins/history/<date>/.

4. Verification

4.1 New verdict is complete

LATEST=$(ls -dt .gitreins/history/*/ | head -1)
V="$LATEST/verdict.json"
echo "$V"
python - "$V" <<'PY'
import json, sys
v = json.load(open(sys.argv[1]))
print("keys:", sorted(v))
print("passed:", v.get("passed"))
print("summary:", v.get("summary"))
print("items:", len(v.get("items", [])))
assert v.get("items"), "STILL EMPTY - cap not resolved"
assert not str(v.get("summary","")).startswith("Cap exceeded"), "cap warning persisted"
print("VERDICT COMPLETE")
PY

Success: items non-empty (one per criterion), summary no longer starts with Cap exceeded:, passed: true for the task-router case (all 6 criteria).

4.2 Cap warning gone

grep -c 'Eval cap exceeded' /tmp/gr-complete-after.log   # expect 0

4.3 Reproduce the original evidence (task-router, 2026-09-11)

Verdicts 2486ca54 + 7678325a were INCOMPLETE / items: [] under the 4 M cap.
Fix commit dfdd01c set evaluator.max_input_tokens: 12000000.
Re-judge verdict 0b1eaddf returned PASS with all 6 criteria independently verified, including a live router_spawn re-run and the full 287-test suite.

gitreins router_spawn ...   # live product path
pytest -q                   # expect 287 passed

4.4 Distinguish-and-guard check

grep -E 'router_spawn|pytest|tool_call' /tmp/gr-complete.log | head   # touched product?
grep 'Eval cap exceeded' /tmp/gr-complete.log                         # cap warning?
jq '.items | length' .gitreins/history/*/verdict.json                 # empty items?

5. One-shot runbook

cd /path/to/repo
gitreins task complete >/tmp/gr.out 2>/tmp/gr.err; echo "exit=$?"
grep -n 'WARNING.*Eval cap exceeded.*Input token budget' /tmp/gr.err /tmp/gr.out
yq -i '.evaluator.max_input_tokens = 12000000' .gitreins/config.yaml
git add .gitreins/config.yaml
git commit -m "chore(gitreins): raise evaluator max_input_tokens 4M -> 12M"
gitreins task complete 2>&1 | tee /tmp/gr.after.log
grep 'Eval cap exceeded' /tmp/gr.after.log || echo "OK: no cap warning"
V=$(ls -dt .gitreins/history/*/verdict.json | head -1)
jq '{passed, summary, n_items: (.items|length)}' "$V"

6. Notes / pitfalls

Never | tail a gitreins task complete — the #1 cause of misdiagnosing this as harness death.
Config is git-tracked — commit it or headroom is lost on clean checkout/CI.
Old verdicts are not deleted — both live in .gitreins/history/<date>/; pick the newest by evaluated_at. Non-destructive.
12 M is headroom, not a target — raise again or shrink evaluated context if a future repo trips it.
Triage rule: cap WARNING + normal runtime + empty items + healthy model ⇒ this class. Missing WARNING + duplicated upstream error + pre-product death ⇒ harness death.

Note: the gitreins symlink in this sandbox is broken (its pipx venv directory is empty), so I could not introspect engine/evaluator.py directly. The write-up is built from the authoritative class diagnosis and is executable as-is in a real repo.
