From b5a29b05e12f30f167a57aabf88fce8456ac912d Mon Sep 17 00:00:00 2001 From: Kai Date: Fri, 28 Aug 2026 01:10:58 -0700 Subject: [PATCH] docs: mark phase 3 complete, record the skills and caching findings Two findings that changed the plan rather than confirming it: 23. Skills require a tool literally named `read`. Curator's tools are all domain-specific, so every --skill argument was discarded in silence. The planned split into curator-core / video-arr / books-ingest was inert before it was written; the policy stays in APPEND_SYSTEM.md. memo-inbox is unaffected because it registers a restricted `read` override, which is why the earlier note generalised wrongly from it. 24. A long-lived session is worth far more than the startup it saves: 99.97% of input read from cache on a continuing conversation against 0% on a new one. That is what makes the generated tool list necessary rather than merely tidy -- anything varying at the front of the prompt destroys it -- and it makes rotation a cost to be bounded rather than applied eagerly. profile.toml now describes the phase-3 configuration that is actually deployed, including that the empty `skills` list is a finding and not an oversight. pi_rpc gains --system-prompt support and no longer guesses whether a `read` tool will exist; extension_registers_read has to be stated. harness-layering.md records what transfers from a widely-shared account of building a personal coding harness on pi, and what does not. The layering frame holds and the cache-hit figure was the useful part. Its central recommendation -- installing third-party packages -- is disqualifying for an unattended agent holding tracker credentials, and its discipline layer (AGENTS.md) is precisely what we block, because it is discovered from every parent directory. --- docs/harness-layering.md | 100 ++++++++++++++++ docs/pi-runtime-notes.md | 65 +++++++++++ docs/plans/2026-08-curator-agent-refactor.md | 37 +++++- scenarios/curator/profile.toml | 110 ++++++++++++------ scenarios/curator/workspace/.pi/SYSTEM.md | 57 ++++++++- ...{SYSTEM.phase3.md => SYSTEM.structured.md} | 59 ++-------- shared/lib/py/pi_rpc.py | 49 ++++++-- shared/lib/py/tests/test_pi_rpc_smoke.py | 26 +++++ 8 files changed, 401 insertions(+), 102 deletions(-) create mode 100644 docs/harness-layering.md rename scenarios/curator/workspace/.pi/{SYSTEM.phase3.md => SYSTEM.structured.md} (55%) diff --git a/docs/harness-layering.md b/docs/harness-layering.md new file mode 100644 index 0000000..f3949e8 --- /dev/null +++ b/docs/harness-layering.md @@ -0,0 +1,100 @@ +# Harness layering, and which parts transfer to a dedicated agent + +Notes taken from a widely-shared account of building a personal *coding* harness on +pi ([@chasen_liao, 2026-08-27](https://x.com/chasen_liao/status/2092963119337476137)), +checked against what this repository actually runs. Recorded because the layering +is a good frame and because several of its specifics are actively wrong for a +service-embedded agent — and the reasons are worth stating once rather than +rediscovering. + +## The frame: three layers + +| layer | coding harness | this repository | +|---|---|---| +| discipline — durable, always loaded | global + project `AGENTS.md` | `.pi/SYSTEM.md` + `.pi/APPEND_SYSTEM.md` | +| capability — loaded when needed | Skills, hidden by default | tool list generated into the system prompt | +| control plane | third-party packages | one scenario extension + a loopback bridge | + +The frame holds. What differs is every mechanism, and the differences are not +stylistic. + +## What transfers + +**Discipline belongs in a durable file, not in each request.** We reached the same +place from the opposite direction: per-request restatements of "which adapters +exist" were removed in phase 2 because they varied the prompt prefix and cost +cache hits (`pi-runtime-notes.md` §24). + +**Don't pile on capabilities.** "Several dozen enabled made routing worse" matches +the reason Curator exposes five tools and not fifteen. Every tool is a branch the +model can take wrongly. + +**Watch where context goes.** The article uses `pi-context-usage` for this. We take +the same numbers from `message_update.usage` in the RPC stream, which costs nothing +extra, and write them to `control_events` per turn. The article's reported 98% +cache hit is the single most useful figure in it, and it is what justified phase +3b's long-lived sessions; we measure 99.97% on a continuing conversation. + +**One writer at a time.** Their rule for parallel subagents ("only one writer per +directory; reviewers may run in parallel because they are read-only") is the same +shape as Curator's: many read tools, exactly one write path through +`CuratorService`. + +**No claiming done without evidence.** Their coding loop insists on it; Curator +enforces it mechanically, generating receipts from `tool_execution_end` rather than +letting the model narrate what it did. + +**pi has no sandbox and runs at full privilege.** Stated as a closing caution +there; recorded as `pi-runtime-notes.md` §20 here, and the reason isolation is four +layers rather than a flag. + +## What does not transfer, and why + +**Third-party packages.** `pi install npm:...` is the article's main recommendation. +For a dedicated agent it is disqualifying: a package runs arbitrary code in the +same process as the agent, and Curator's whole posture is that the agent reaches +exactly five audited endpoints over loopback. The article says as much in passing +("look at the source and permissions before installing") — advice that scales to a +human's interactive tool and not to an unattended service holding tracker +credentials. `no_extensions = true` plus one reviewed extension stays. + +**`AGENTS.md` as the discipline layer.** For an interactive agent in a repository +this is right. For us it is precisely the thing to block: `AGENTS.md` is discovered +from *every parent directory* of the workspace, so a file written for an unrelated +project leaks in. `--no-context-files` is the only switch that stops it, and it is +on. Discipline lives in the system-prompt files, which that flag does not touch. + +**Skills as the capability layer.** Cannot work here at all: pi emits the skills +section only when a tool named `read` is active, and Curator's tools are all +domain-specific, so every `--skill` argument is discarded in silence +(`pi-runtime-notes.md` §23). The capability layer is generated into the system +prompt instead. + +Beyond the mechanism, on-demand loading is *undesirable* for us: it varies the +prompt prefix, and a varying prefix is exactly what destroys the cache hit the +article is celebrating. Interactive sessions can afford it; a per-message service +cannot. + +**Subagents and parallel lanes.** Curator answers one message about one library. +There is no plan to decompose. The article's own caution — "don't force the full +workflow onto a small task" — applies, and here every task is small. + +**`$`-expansion, `/btw`, `/goal`, `/context`, TUI packages.** All interactive +affordances for a human at a terminal. Curator has no human at a terminal; it has +Telegram and an HTTP server. + +**`pi-ask` for stopping at ambiguity.** The instinct is right and Curator has an +equivalent, but it cannot be a tool: a Telegram round-trip is not a blocking +prompt. Ambiguity is handled by the `clarify` intent, and the harder rule is that +ambiguity must resolve towards *reading*, not asking — phase 0 removed a +`clarify → library_query` rewrite that was guessing, while phase 3 keeps "when a +message is only a title, query rather than ask what the user wants". + +## The transferable conclusion + +The article's actual thesis is not its package list, it is that a small core plus +your own assembly beats a fixed harness. That is the same conclusion this +repository reached, with the opposite emphasis: for an unattended agent holding +real credentials, most of the assembly is deciding what *not* to load, and every +capability has to be justified against what it would cost if the model were +adversarial rather than merely wrong. diff --git a/docs/pi-runtime-notes.md b/docs/pi-runtime-notes.md index aacacef..7a596f9 100644 --- a/docs/pi-runtime-notes.md +++ b/docs/pi-runtime-notes.md @@ -501,6 +501,71 @@ instructions under `--system-prompt`; they have to be in the prompt text. --- +## 23.
