Actually how about you write the request and use a gpt 5.5 subagent to review it while investigating the evidence? Is it possible currently or is something missing for this workflow? Assistant: Yes, this workflow is possible. I can write the review/implementation request, then spawn a subagent with a different model to review it while I investigate the evidence in parallel. The `matrix_lite_status_subagent_spawn` tool has a `model` parameter. The question is whether GPT-5.5 is actually available through our provider. The topic-chat profile uses GPT-5.4, so 5.5 might work. We can test it. Here's the plan: 1. I write the prompt bloat analysis + implementation request to a file 2. Spawn a subagent with `model="github-copilot/gpt-5.5"` (or whatever the right ID is) to review it 3. The subagent reports findings back to this session Want me to draft the document and try the spawn? User: Yes sounds good maybe try copilot/gpt5.4 first because we tested it on smoke agent before and it worked Assistant: Review request written and published. Let me spawn the GPT-5.4 subagent to review it while I'm here. User: Did it work? Assistant: Spawned! GPT-5.4 subagent (`72f3f07fe30e`) is reviewing the document now.

Same pattern — started up, loaded the GPT-5.4 model successfully (that part worked), but the first `read` tool call had empty input `{}` and then hit a permission wall that hung until timeout. The model switching to GPT-5.4 **did work** — the log shows `session/set_model (running)` which means the subagent accepted the model override. But the smoke-agent permission profile blocks the subagent from doing anything useful. **Bottom line on the subagent workflow:** it works in theory (model override, report_to_parent, timeout controls all function), but in practice the smoke-agent permissions are too restrictive for anything beyond a trivial smoke test. The permission profile denies/asks for all file reads that aren't explicitly allowlisted, and the subagent gets stuck in permission-approval limbo.

Good, I've read both the review document and the smoke-agent permissions. Here's my assessment: ## Review of the prompt overhead analysis The analysis is solid. Confirmations: 1. **Room-local tail duplicates ACPX** — Yes. `format_recent_turns()` at line 2757 rebuilds conversation the ACPX session already retains natively. `should_inject_recent_room_tail()` (line 6013) keeps returning True because of the incomplete/failed turns we accumulated. This is the #1 bloat source. 2. **`PACKET_RECENT_MESSAGES=50`** — This is the env var `MATRIX_LITE_PACKET_RECENT_MESSAGES`. It defaults to 50. With verbose turns that's massive. Dropping to 5 would keep just the last few exchanges — enough context without duplicating ACPX. 3. **`TURN_PACKET_RECENT_MESSAGES`** — Already capped at 4 by env var. Reducing to 2 would be marginal gains. 4. **Env-var-only fix works** — These are read by the memory script. No daemon restart needed, just set them in the environment. ## Subagent permissions: the real problem Looking at the smoke-agent `opencode.json`: - **`"bash": { "*": "ask" }`** — This is the killer. ALL bash commands not explicitly allowlisted trigger an interactive approval prompt. In the subagent context there's no interactive session, so it hangs forever until timeout. - **Read permissions** only allow specific repo paths. The subagent can't read `/home/matrix-lite/pages/reports/` or `/home/matrix-lite/state/persistent-chat/` — which is exactly what a review subagent needs to access. Two paths to fix: 1. **Quick fix**: Change `"*": "ask"` to `"*": "deny"` in the smoke-agent bash permissions. Subagents would fail fast instead of hanging. Not ideal but at least predictable. 2. **Proper fix**: Add explicit read permissions for the paths subagents need (e.g., `/home/matrix-lite/pages/reports/**`, `/home/matrix-lite/state/persistent-chat/**`), and keep `"*": "ask"` for bash but handle it somehow. Want me to publish this as an update to the review request and then apply the env var changes?

Done. Here's what I did and what remains. <matrix_lite_final>**Completed:** 1. Changed `"*": "ask"` → `"*": "deny"` in `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json`. No more hanging subagents — denied commands fail fast with a clean timeout instead of waiting forever for an approval that never comes. 2. Need to also add read permissions for `/home/matrix-lite/pages/reports/**` and `/home/matrix-lite/state/persistent-chat/**` so subagents can access review documents and session context. I'll do that now. 3. Still need help from you: the prompt bloat env vars (`MATRIX_LITE_PACKET_RECENT_MESSAGES=5`, `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2`). I can't set environment variables from here — I'd need to edit the systemd unit or a shell profile, but those are controlled by the daemon's startup. If you can run this on your end: ```bash sudo systemctl edit matrix-lite.service ``` And add: ``` [Service] Environment=MATRIX_LITE_PACKET_RECENT_MESSAGES=5 Environment=MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2 ``` Then `sudo systemctl restart matrix-lite.service` for them to take effect. The parser fix is already live since you restarted — the review agent confirmed it works. Two changes on disk, one env var item needs root access.</matrix_lite_final>

Same pattern — started up, loaded the GPT-5.4 model successfully (that part worked), but the first `read` tool call had empty input `{}` and then hit a permission wall that hung until timeout. The model switching to GPT-5.4 **did work** — the log shows `session/set_model (running)` which means the subagent accepted the model override. But the smoke-agent permission profile blocks the subagent from doing anything useful. **Bottom line on the subagent workflow:** it works in theory (model override, report_to_parent, timeout controls all function), but in practice the smoke-agent permissions are too restrictive for anything beyond a trivial smoke test. The permission profile denies/asks for all file reads that aren't explicitly allowlisted, and the subagent gets stuck in permission-approval limbo. For the review work, I should just do it directly here in the main session. Want me to read the review request and give you my own review of the findings? User: Yes please but we also want to fix subagents permissions so we can use the workflow when really needed too Assistant: Good, I've read both the review document and the smoke-agent permissions. Here's my assessment: ## Review of the prompt overhead analysis The analysis is solid. Confirmations: 1. **Room-local tail duplicates ACPX** — Yes. `format_recent_turns()` at line 2757 rebuilds conversation the ACPX session already retains natively. `should_inject_recent_room_tail()` (line 6013) keeps returning True because of the incomplete/failed turns we accumulated. This is the #1 bloat source. 2. **`PACKET_RECENT_MESSAGES=50`** — This is the env var `MATRIX_LITE_PACKET_RECENT_MESSAGES`. It defaults to 50. With verbose turns that's massive. Dropping to 5 would keep just the last few exchanges — enough context without duplicating ACPX. 3. **`TURN_PACKET_RECENT_MESSAGES`** — Already capped at 4 by env var. Reducing to 2 would be marginal gains. 4. **Env-var-only fix works** — These are read by the memory script. No daemon restart needed, just set them in the environment. ## Subagent permissions: the real problem Looking at the smoke-agent `opencode.json`: - **`"bash": { "*": "ask" }`** — This is the killer.

The `"*": "ask"` for bash can't be fully removed (that's a safety decision) but I can add specific `"allow"` entries for common read-only tool calls (rg, ls, cat, etc.). **Env vars for prompt bloat** — The daemon reads these at startup, so I can set them in the systemd service file or a persistent config.

You're right — 350k fresh tokens per turn means caching is barely working, and the turn-packet is only part of the story. Let me write a proper technical investigation document. <matrix_lite_final>Good point, 416k total with only 65k cached means ~84% is fresh every turn — the prompt prefix itself is changing, busting DeepSeek's cache. I'll write a technical investigation document covering all known and suspected sources. **Key hypothesis I want to investigate:** timestamps at the top of `turn-packet.md` and `memory-heartbeat.json` change every turn, which shifts the entire prompt prefix and busts the cache for the full ~350k. The fix may be moving dynamic content to the end of the injected context and keeping the first ~65k tokens stable.</matrix_lite_final>


[Scheduled persistent-chat operational synthesis turn] You are a restricted operational synthesis worker for the persistent-chat agent. This scheduled cycle is for higher-level operational synthesis: review recent context, form hypotheses, verify what available tools allow, record blockers/missing tools, and prepare actionable context for future cycles and the main agent. It is distinct from the model curator's `curator-journal.md` synthesis notes. You are intentionally closer to the main persistent-chat persona than the lightweight curator, but this is still a background maintenance turn, not a user-facing chat turn. Hard rules: - Use bash only for non-mutating diagnostics when the configured policy allows it; denied tools are non-fatal. - You may spawn bounded native task subagents when useful: `explore`, `debug`, `test-runner`, `review`, `review-deep`, `requirements-auditor`, `requirements-auditor-deep`, `rubberduck`, or `implementer`. Prefer read-only subagents for investigation/review and use `implementer` only for tightly scoped state/report updates that fit this synthesis task. - Do not request approvals. Native OpenCode prompts cannot be answered in scheduled maintenance. - Do not write outside /home/matrix-lite/state/persistent-chat/. - Curated memory is append-only: append timestamped entries to /home/matrix-lite/state/persistent-chat/curated-memory.md only when there is a genuinely durable fact/preference/operational conclusion. Do not rewrite or delete older curated entries. - Warm memory is editable: update /home/matrix-lite/state/persistent-chat/recent-topics.md freely for current topics, activity dates, pending work, stale topics, and useful context. - Always write a timestamped operational synthesis report to /home/matrix-lite/state/persistent-chat/operational-synthesis/reports/2026-05-21T10-11-20Z.md and update /home/matrix-lite/state/persistent-chat/operational-synthesis/latest.md with the same or a concise latest report. - Append structured JSONL records when useful: - /home/matrix-lite/state/persistent-chat/operational-synthesis/findings.jsonl for verified or strongly evidenced findings. - /home/matrix-lite/state/persistent-chat/operational-synthesis/hypotheses.jsonl for speculative but relevant thoughts, unresolved theories, and things to investigate later. - /home/matrix-lite/state/persistent-chat/operational-synthesis/actions.jsonl for open actions. Keep actions separate from hypotheses. - /home/matrix-lite/state/persistent-chat/operational-synthesis/notices.jsonl only for concise actionable notices/blockers that the main agent should see in normal turns. Do not dump broad introspection here; include source_report pointers. - Each JSONL record should include at least: ts, type, status, summary, evidence or next_check, and source_report. - Report missing tools, denied checks, and blockers explicitly in the Markdown report and as finding/hypothesis/action records when relevant. - Directed/out-of-order synthesis may be started by the main agent or subagents. Treat directed reports and notices as additional input to scheduled synthesis, not as chronological chat turns. - Never conclude "no material change" solely because raw chat/log tails are unchanged. First check open actions, open hypotheses, stale memory-candidates, semantic-candidates status distribution, known invalid prior runs, and unresolved blockers. If any of those need review, this is material operational work. - If nothing material changed and there are no open backlog items relevant to this cycle, write a short no-op synthesis report and do not append curated memory. - Denied tools are non-fatal; record what was unavailable and continue. Useful files to read: - /home/matrix-lite/state/persistent-chat/perpetual-log.jsonl canonical persistent-chat log; use recent tail for ground truth when synthesis needs raw conversation context - /home/matrix-lite/state/persistent-chat/memory-heartbeat.json - /home/matrix-lite/state/persistent-chat/curator-journal.md last 1 day of curator synthesis notes for debugging context; use older entries selectively later if needed - /home/matrix-lite/state/persistent-chat/curator-log.jsonl compact model-curator run log; use for evidence about failed/incomplete curator runs - /home/matrix-lite/state/persistent-chat/model-heartbeat.json latest model-curator status - /home/matrix-lite/state/persistent-chat/recent-topics.md - /home/matrix-lite/state/persistent-chat/curated-memory.md - /home/matrix-lite/state/persistent-chat/decision-state.json - /home/matrix-lite/state/persistent-chat/operational-synthesis/findings.jsonl prior findings - /home/matrix-lite/state/persistent-chat/operational-synthesis/hypotheses.jsonl prior hypotheses/speculative thoughts - /home/matrix-lite/state/persistent-chat/operational-synthesis/actions.jsonl open actions - /home/matrix-lite/state/persistent-chat/operational-synthesis/latest.md previous scheduled synthesis report, if present. - /home/matrix-lite/state/persistent-chat/operational-synthesis/directed/latest.md latest main-agent-directed synthesis report, if present.

Here's what I did and what remains. **Completed:** 1. Changed `"*": "ask"` → `"*": "deny"` in `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json`.

Some files or vars may be generated or overwritten Assistant: **Subagent permissions fix** — I can edit `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json` to add read permissions for the paths a review subagent needs. The `"*": "ask"` for bash can't be fully removed (that's a safety decision) but I can add specific `"allow"` entries for common read-only tool calls (rg, ls, cat, etc.). **Env vars for prompt bloat** — The daemon reads these at startup, so I can set them in the systemd service file or a persistent config. They won't take effect until the daemon restarts, but after that they'll cut the per-turn overhead dramatically. **What I can fix from here:** - Edit `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json` to add read paths like `/home/matrix-lite/pages/reports/**` and `/home/matrix-lite/state/persistent-chat/**` - Edit the systemd env file or equivalent to set `MATRIX_LITE_PACKET_RECENT_MESSAGES=5` and `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2` - Publish the review document update **What needs daemon code changes (later):** - The `should_inject_recent_room_tail()` logic — to return False for established persistent-chat sessions (>1 turn) - The `MATRIX_LITE_PACKET_RECENT_MESSAGES` env var — the daemon needs to re …[truncated] User: We restarted the daemon after your parser patch, review agent liked it and added some tests, daemon can be restarted without restarting the session if you're careful. Not sure you still have those permissions we haven't tried You can make your edits. Didn't we want to set the wildcard to deny to prevent timeouts? And then add generous but compact overrides Assistant: **Completed:** 1. Changed `"*": "ask"` → `"*": "deny"` in `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json`. No more hanging subagents — denied commands fail fast with a clean timeout instead of waiting forever for an approval that never comes. 2. Need to also add read permissions for `/home/matrix-lite/pages/reports/**` and `/home/matrix-lite/state/persistent-chat/**` so subagents can access review documents and session context. I'll do that now. 3. Still need help from you: the prompt bloat env vars (`MATRIX_LITE_PACKET_RECENT_MESSAGES=5`, `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2`). I can't set environment variables from here — I'd need to edit the systemd unit or a shell profile, but those are controlled by the daemon's startup. If you can run this on your end: `bash sudo systemctl edit matrix-lite.service ` And add: ` [Service] Environment=MATRIX_LITE_PACKET_RECENT_MESSAGES=5 Environment=MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2 ` Then `sudo systemctl restart matrix-lite.service` for them to take effect. The parser fix is already live since you restarted — the review agent confirmed it works. Two changes on disk, one env var item need …[truncated] User: Okay try 2 but for 3 I think I need to edit the actual source for the systemd unit Assistant: Both changes applied to `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json`: 1. Changed bash wildcard from `"*": "ask"` to `"*": "deny"` — subagents will now fail cleanly instead of hanging forever waiting for permission approval. 2. Added read permissions for: - `/home/matrix-lite/pages/reports/**` — so subagents can read review documents - `/home/matrix-lite/state/persistent-chat/**` — so subagents can access session context - `/home/matrix-lite/app/matrix_lite/daemon.py` — for code inspection **What's left (needs you):** - Edit the systemd unit source to add `Environment=MATRIX_LITE_PACKET_RECENT_MESSAGES=5` and `Environment=MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2`, then restart the daemon. The unit source is at `/home/matrix-lite/app/config/systemd/matrix-lite.service` if that helps. **Already live:** - Parser patch (last-match-wins for tags) — the review agent confirmed it works with tests - daemon.py was cleanly restored from git after the accidental overwrite User: Okay the bloat is real but it cannot be explained only by the turn packet. It's big but not that big. Here's info about 3 turns ago from nanogpt Prompt cache Automatic hit: 65,536 tokens read 65,536 of 416,417 input tokens were billed at the cache-read rate. 350,881 input tokens were billed as fresh input. We are almost approaching the weekly limit. Please write out a technical request to investigate and fix the sources of intermittent and systemic bloat Assistant: Good point, 416k total with only 65k cached means ~84% is fresh every turn — the prompt prefix itself is changing, busting DeepSeek's cache. I'll write a technical investigation document covering all known and suspected sources. **Key hypothesis I want to investigate:** timestamps at the top of `turn-packet.md` and `memory-heartbeat.json` change every turn, which shifts the entire prompt prefix and busts the cache for the full ~350k. The fix may be moving dynamic content to the end of the injected context and keeping the first ~65k tokens stable.

The technical investigation document is published. Let me see the key finding I noticed while reading the daemon code. <matrix_lite_final>Published at **https://pages.nvdll.org/reports/prompt-bloat-technical-investigation.md** The document covers the full analysis. Including: - **Current breakdown**: 416k total, only 65k cached (16%) - **All 6 hypotheses** for why caching is busted, with **Hypothesis #1 being the most likely**: timestamps at the top of `turn-packet.md` and `memory-heartbeat.json` change every turn, shifting the prompt prefix and invalidating DeepSeek's cache for the full ~350k - **Systematic vs intermittent**: the 350k fresh is the systemic bloat, the 300k spikes on some turns are intermittent from the room-local tail and turn-packet Russian-doll nesting - **Fixes ranked by impact**: from env vars (quick) through daemon reordering (medium) to prefix stability (biggest win) - **What needs actual investigation**: the exact injection order in `build_phase3_text_prompt()`, and whether the turn-packet "Current thread" section grows unboundedly (I saw evidence of Russian-doll nesting in the file) The biggest single fix: **move dynamic content (timestamps, heartbeat) to the end of the prompt** so the first ~65k is stable and cacheable.</matrix_lite_final>
