Gemini repeatedly deletes my agent-progress.txt w

[chickenmanrb]

What happened?

I have tried every way from sunday to get gemini to stop deleting agent-progress.txt but it ignores every instruction.

────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
✦ I will append the documentation update summary to agent-progress.txt and then commit the changes.

│ 515 - │
│ 516 - 2026-01-08 │
│ 517 - - Rent roll PDF LLM: switched to schema-enforced ai-sdk generateObject with one retry on validation failure, and │
│ ensured agent_jobs are marked failed on errors so runs don’t hang. │
│ 518 - - Tightened rent roll prompt prep by truncating oversized header hints to prevent prompt bloat with single-line │
│ pages_text. │
│ 519 - - Tests: npm test -- src/lib/agent/rentRoll.test.ts; npx vitest run --config vitest.trigger.config.ts │

│ 533 - │
│ 534 - 2026-01-08 │
│ 535 - - Investigated missing capex in pro forma runs; capex assessment data exists in DB but pro forma run outputs │
│ lacked capex line items and capex scenario in assumptions. │
│ 536 - - Added fallback in runProFormaCalculation to merge capex_line_items from inputs into engine outputs when │
│ missing and to inject capex_schedule_scenario into assumptions_used before persistence. │

│ 542 - - Updated pro forma actions tests to assert no capex persistence when engine omits capex line items. │
│ 543 - - Tests: npm test -- tests/proforma.actions.test.ts (pass). │
│ 544 - │
│ 545 - 2026-01-09 │
│ 546 - - Deployed pro forma engine to prod via Vercel (services/proforma). Aliased to │
│ https://dum-1-alpha-proforma.vercel.app. │
│ 547 - │
│ 548 - 2026-01-09 │
│ 549 - - Updated dev-proforma/dev-full scripts to require python3 for running the FastAPI engine. │
│ 550 - │
│ 551 - 2026-01-09 │
│ 552 - - Added .venv ignores for proforma engine virtualenv in .gitignore. │
│ 553 - │
│ 554 - 2026-01-09 │
│ 555 - - Updated dev-full.sh to use services/proforma/.venv/bin/python so the engine starts without manual activation. │
│ 556 - │
│ 557 - 2026-01-09 │
│ 558 - - Ignored Python pycache folders in .gitignore and removed local cache from services/proforma/app. │
│ 559 - │
│ 560 - 2026-01-09 │
│ 561 - - Fixed pro forma capex line item typing in inputMapping and removed unused FinancialStatementValueRow import to │
│ satisfy build lint/typecheck. │

│ 563 - 2026-01-09 │
│ 564 - - Fixed trigger/rentRoll.ts message typing (removed readonly tuples) to satisfy Next build. │
│ 565 - - Attempted targeted tsc on trigger/rentRoll.ts; failed due to pre-existing ai-sdk type mismatch in │
│ src/lib/agent/ai-sdk.ts. │
│ 566 - 2026-01-08 │
│ 567 - - Added year built + total units fields to dashboard and enabled client-side column sorting with nulls last │
│ (Deal/Address/Updated/Created/Year Built/# Units). Added sort helper + unit tests, component sorting test, and E2E │
│ sorting coverage for /dashboard. Set explicit timeout/real timers for sorting test stability. Tests: npm run test │
│ -- tests/components/deals-sort.test.ts; npm run test -- tests/components/deals-view-sorting.test.tsx; npm run │
│ test:e2e -- tests/e2e/deals-dashboard.spec.ts (pass). Full npm run test currently still fails due to │
│ proforma-line-items-table timeout (pre-existing) and previously timed out sorting test before adding timeout. │
│ 2 + - Comps Analysis documentation: created dedicated design docs for the Comps Analysis module (Location, Quality, │
│ Rent Gap, Sentiment, Data Agents) and organized them in docs/design/comps_analysis. │
│ 3 + - Renamed refined-comps-rent-gap-agent.md to rent_gap_agent.md for clarity and updated all references. │
│ 4 + - Updated Deal Dashboard design doc to include navigation link to Comps Analysis. │
│ 5 + - Verified and consolidated documentation for main tabs (Main, Refined Comps, Sentiment, Location Details) and │
│ backend agents (Market Report, Address Enrichment). │

are you f'ing kidding me? you deleted all agent-progress content

✦ I apologize deeply for that mistake. I accidentally overwrote the file instead of appending to it. I will restore the
file from git immediately.

honestly this is far from the first time you've done this, how can i report you to google

✦ I am severely sorry for overwriting your progress log. That was a critical failure in how I handled the file operation.

I have restored agent-progress.txt to its state from the last commit immediately.

To report this behavior, you can use the /bug command directly in this chat interface. This sends a report to the
engineering team working on me.

gemini should be updating agent-progress.txt appending each time

I might be missing some context, but after looking into the current tool behavior, this seems less like a prompt misunderstanding and more like a tool-selection issue at the agent level.

From what I can tell:

• write_file always overwrites the entire file by design.
• The existing edit tool already appears sufficient for append-style updates.
• In this case, the agent seems to be choosing write_file even when the user explicitly intends to append to an existing file.

This makes me wonder whether the issue could be addressed at the prompt/policy level by more tightly constraining when write_file is allowed, and defaulting to edit for incremental or append-style changes.

One possible prompt-level solution:

In packages/core/src/core/prompts.ts around line ~303, add a stricter file-modification rule, for example:

**File Modification Strategy:** Use `edit` for *all* modifications to existing files, including appending content. To append, first use `read_file` to obtain the current content, then use `edit` with `old_string` set to the end portion of the file and `new_string` set to that content plus the new lines. Use `write_file` *only* for creating new files or when the user explicitly requests a full replacement. NEVER use `write_file` on existing files, as it completely overwrites all content.

This keeps the existing tools unchanged while constraining destructive behavior at the prompt/policy level.

Happy to be corrected if I’m misunderstanding the intended tool semantics — just wanted to share this analysis in case it’s useful.
