Session 8

Date: 2026-04-07 Focus: Close #54 — wire confidence fields into write_cache tool schema Duration estimate: ~15 minutes

What was done

Audited #54 against current code. Found the work was 90% already done: _DIR_SYSTEM_PROMPT already instructs the agent to set confidence / confidence_reason (landed earlier in commit 80f8f88, issue #2). The only remaining gap was the write_cache tool's data schema description in _DIR_TOOLS (ai.py:246), which still listed only the legacy fields.
Branched fix/issue-54-write-cache-tool-desc, added confidence and confidence_reason to the tool's data field description plus a one-line pointer back to the system prompt for calibration.
Tests: python3 -m unittest discover -s tests/ → 168 pass.
PR archeious/luminos#61 → merged --no-ff (4ef97c5) → branch deleted local + remote → PR closed → issue #54 closed.
Phase 1 milestone is now 4/4 complete.

Discoveries and observations

All MCP writes worked end-to-end as claude-code — PR create, PR close, issue close all went through the gitea MCP without falling back to REST. The Session 7 credential overhaul is paying off immediately.
Models bind tightly to tool schema descriptions; instructing them only via the system prompt and not in the tool schema is a fragile pattern. Worth remembering as a general principle for future tool-bound work.

Decisions made and why

Did not change the float-vs-categorical confidence representation even though the issue notes categorical is "probably more reliable." That's a separate calibration experiment, not a prerequisite for closing #54. Banded floats with explicit thresholds (high ≥ 0.8, medium 0.5–0.8, low < 0.5) is the current contract; changing it touches low_confidence_entries and the eventual Phase 8 refinement signal.
Deferred the manual --ai verification run mentioned in the issue's acceptance criteria. The schema change is straightforward and the unit tests cover the cache validation path; doing a real API run for a one-line schema doc tweak would burn budget for low marginal value. We'll pick it up the next time we're running --ai for any reason.

Raw thinking

Phase 1 closing was a tiny session, but it's a real milestone closure — worth marking. The remaining backlog from Session 5 follow-ups (#55, #56, #57) is now the only thing standing between us and Phase 3 proper.
The model does have a tendency to skip optional schema fields if the description doesn't make them feel important. Worth verifying after the next --ai run that confidence is actually landing — if it's still inconsistent, may need to make the field required in the cache schema rather than just documenting it.
The categorical-vs-float question is still open. Filing it as a separate Phase 8 prerequisite would be cleaner than letting it haunt #54.
This is the second time the gitea MCP got used for an end-to-end write workflow (PR create + close + issue close) and it just worked. The collaborator-permission caveat in ~/.claude/CLAUDE.md is the only friction left.

What's next

In priority order:

#57 — refactor _run_dir_loop before Phase 3 dynamic turn allocation lands. Prerequisite cleanup, small.
#56 — dedupe _TOOL_DISPATCH / _DIR_TOOLS registration. Small, satisfying.
#55 — unit test coverage for ai.py pure helpers. Foundation for Phase 3 confidence work.
Phase 3 proper (#19–#29 cluster).
