From 1f83bff5e2cc921de03e13f6abc5460db9c26c31 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Thu, 6 Aug 2026 11:43:31 +0200 Subject: [PATCH 1/7] Offer PATH-detected cc-harness agents at /kickoff (1.12.0) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a `cc-harness-agents` helper is on PATH, /kickoff merges its foreign agents into the picker: full Claude Code sessions driven by a foreign model (cc-harness:grok, :kimi, :sol) via a local gateway. Auto-detected via one `command -v`; helper absent means no change from today. - agent-registry.sh: merge the helper's 4-column TSV (name/model/available/ note) into the 5-column list as cli=cc-harness, map only literal `available=yes` to available (fail closed on `unknown`), and resolve cc-harness: to `cc-harness-agents exec -- claude [-n ] /work-system:continue` — no --model, the helper sets it via env before exec'ing into claude, so the herdr pane roots at claude and agent_status + /close stay intact. - Helper exit 3 (capability absent) is a silent degrade, distinct from a listed-but-unavailable provider (resolve exit 3 + the helper's fix hint). - No per-agent code: whatever `list` prints becomes a picker entry — tested with a name the plugin has never shipped. - Lifecycle parity: supports= is the full claude set; a committed cc-harness: default validates through the helper and falls back to the picker when it is gone. - Docs: plugins/work-system/docs/cc-harness-agents.md (contract + setup), knowledge, READMEs, CHANGELOG; kickoff/adopt picker prose.

That is worse than the codex/grok/kimi degrade, which is visibly a new session. Documented inline with the manual form (`cc-harness-agents exec -- claude -c`) instead of claiming unqualified lifecycle parity. - Sanitize helper fields at ingest: strip C0 controls + DEL and cap the length. A note is rendered as an authoritative hint and enters the picker's context — same risk class the `--session` guard already covers. Unicode bidi/zero-width overrides remain a documented residual. - Split the helper's TSV explicitly. `IFS=$'\t' read` treats tab as IFS whitespace and collapses consecutive tabs, so one empty cell shifted every later column (empty model => `available` read as the model, fail-closing a working agent). The trap bit twice: on the helper's output, and where resolve/row_for_name re-read the lookup's own line. - Give `list` and `resolve` one namespace gate. A row missing the `cc-harness:` prefix was rejected by the list builder but still matched the lookup's bare-id clause — invisible yet launchable and storable as a committed default. - Make the picker's 4-option cap satisfiable: the aggregate reserves a slot, natives fill the rest one option per CLI, overflow is named with the `--agent` hint. Classify from `list --json`, not the `column -t` padded table whose note cells contain spaces. - Tests: regressions for each fix; stub emits rows via printf (echo's escape expansion is not POSIX-guaranteed); no-helper cases pin the seam at an absent path instead of trusting the host PATH.

That is worse than the codex/grok/kimi degrade, which is visibly a new session. `/continue`, the README and the docs page now state it inline and give the manual form (`cc-harness-agents exec -- claude -c`) instead of claiming unqualified lifecycle parity; a real fix needs per-task worker persistence. +- Helper rows are sanitized at ingest and parsed positionally.

It is now a fixed ordered rule: the aggregate reserves a slot whenever harness rows exist, natives fill the rest **one option per CLI** (alternates named in the description), and anything still over the cap is named in the question text with the `--agent` hint — never silently truncated. Classification also moved from the `column -t`-padded human table to `list --json`, whose `cli` field is unambiguous (`note` cells contain spaces, so splitting the padded table could misfile a harness row and drop the aggregate entirely). - Fix: `list`'s human table dropped the **last** harness row. `$( )` strips the trailing newline off the merged block, and the table's `while read` then discards the final newline-less line — silently, and only in the table, since `--json` parses it fine.

The helper stub now emits rows with `printf` instead of `echo "…\t…"`: escape expansion by `echo` is not POSIX-guaranteed, so on a host whose `/bin/sh` is bash without xpg_echo every harness assertion would have failed while CI (ubuntu/dash) stayed green.

Also from the same round: - The bare namespace `cc-harness:` passed the gate — listable, resolvable and storable as a committed default while emitting an empty argv word that only failed at launch. Requires a non-empty id now. - The tab-collapse fix had not reached the renderer: `column -t -s TAB` also folds consecutive separators, so an empty model still collapsed on screen (MODEL showing the availability value). Every empty cell is placeholdered before column sees it, and a test asserts the table, not just --json. - One splitter (harness_split) now serves the helper's 4-column rows, the canonical 5-column rows and the display loop. - Helper output is size-bounded, not only time-bounded. - Picker: deterministic page-1 ordering (registry order; claude never dropped) instead of leaving the over-cap choice to improvisation, an explicit page-2 cap rule, and a documented fallback for `list --json`, which hard-requires python3 on a path that had no such dependency. - Dropped the false "no change when the helper is absent" claim: the page-1 grouping applies to everyone. - Shared record emitter across resolve's two arms; the existence-check record carries the id emit_argv would actually need; fork-free sanitizing; knowledge frontmatter refreshed.

Parsing now splits tabs explicitly: `IFS=$'\t' read` treats tab as IFS *whitespace* and collapses consecutive tabs, so a single empty cell shifted every later column (an empty model made `available` read as the model, fail-closing a working agent; the mirror case defeated the fail-closed rule). The trap bit twice — once on the helper's output, once where `resolve`/`row_for_name` re-read the lookup's own line. - `list` and `resolve` now share one namespace gate. A helper row that forgot the `cc-harness:` prefix was rejected by the list builder but still matched `harness_lookup`'s bare-id clause — invisible in `list`/`--json`/the picker, yet resolvable, launchable, and storable as a committed repo default. The match collapsed to the single canonical comparison. - The picker's page-1 rule was unsatisfiable against its own 4-option cap (4 shipped CLIs + the aggregate = 5). It is now a fixed ordered rule: the aggregate reserves a slot whenever harness rows exist, natives fill the rest **one option per CLI** (alternates named in the description), and anything still over the cap is named in the question text with the `--agent` hint — never silently truncated. Classification also moved from the `column -t`-padded human table to `list --json`, whose `cli` field is unambiguous (`note` cells contain spaces, so splitting the padded table could misfile a harness row and drop the aggregate entirely). +- **`list` and `resolve` now share one pipeline**, so "listed" and "resolvable" are the same predicate by construction rather than a convention two functions promised to keep. They had drifted twice: the list path sanitized while the lookup matched the RAW name (a name carrying a control byte, or one past the length cap, was shown in the picker and then exited 2 on resolve), and the list path dropped rows the lookup accepted. `harness_lookup` is now a filter over the canonical rows `list` emits. +- The bare namespace `cc-harness:` with no id no longer passes the gate. It used to list, resolve, and store as a committed default while emitting an **empty argv word** that `herdr-launch` cannot distinguish from a dropped one — so the failure surfaced at launch instead of at selection. +- The human table survives an empty helper cell too. The tab-collapse trap was fixed at ingest first, but `column -t -s $'\t'` treats consecutive separators as one, so an empty model still collapsed *in the renderer* — MODEL showing the availability value, i.e. a working agent reading as unavailable. Every empty cell is now placeholdered before `column` sees it, and a test asserts the table (not just `--json`). +- One TSV splitter (`harness_split …`) serves the helper's 4-column rows, the registry's 5-column canonical rows, and the display loop — the non-collapsing rule lives once instead of being re-derived per call site. +- Helper output is now size-bounded (64 KiB), not just time-bounded: everything it prints is held in shell memory and rendered through the picker. Truncated in-shell rather than through `head -c`, which would SIGPIPE the helper and turn a chatty-but-successful run into an apparent failure. +- Picker: page 1's ordering is deterministic (available CLIs in `REGISTRY` order, then unavailable ones; `claude` never dropped) instead of leaving *which* CLI falls outside the 4-option cap to run-to-run improvisation, and page 2 got the same explicit cap-and-name-the-rest rule. `list --json` now has a documented fallback to the plain table, since `--json` hard-requires `python3` on a path that previously had no such dependency. +- Honesty fix: "no change when the helper is absent" was false — the page-1 grouping rule applies to everyone, because the 7 shipped entries already exceeded the option cap before this feature. Said plainly now. +- `subcmd_resolve`'s two arms share one record emitter, and the fabricated record `row_for_name` hands back for existence checks carries the bare agent id in the slot `emit_argv` would read, so the "must never reach emit_argv" guard is a second line of defence rather than the only thing standing between it and a wrong argv. +- Sanitizing uses parameter expansion instead of a `printf | tr` fork per field. - Fix: `list`'s human table dropped the **last** harness row. `$( )` strips the trailing newline off the merged block, and the table's `while read` then discards the final newline-less line — silently, and only in the table, since `--json` parses it fine. That table is exactly what the picker reads, so the lost row was an agent the user could never choose. Now covered by a test that asserts the table (not just `--json`) and that both views agree on the row count. - Covered by `test_agent_registry.py`: merge list, never-seen agent, argv shape (no `--model`), clean degrade when absent, exit-3 capability-absent, `available=unknown` → no, harness default set/get, plus regressions for each fix above — `list`/`resolve` namespace agreement, empty middle cells in both directions, control-character stripping (and that a sanitized note cannot forge a second `name=` line), and the human table carrying every row. The helper stub now emits rows with `printf` instead of `echo "…\t…"`: escape expansion by `echo` is not POSIX-guaranteed, so on a host whose `/bin/sh` is bash without xpg_echo every harness assertion would have failed while CI (ubuntu/dash) stayed green. The no-helper cases pin `WORK_SYSTEM_CC_HARNESS_AGENTS` at a guaranteed-absent path, so they no longer depend on whether the contributor actually has the helper installed. diff --git a/README.md b/README.md index a9778a1..1bfa8db 100644 --- a/README.md +++ b/README.md @@ -14,7 +14,7 @@ Lightweight, native knowledge management for Claude Code projects.
