From 2ac7f4e01e3f283c63c635e1e8bef937b8f2df70 Mon Sep 17 00:00:00 2001 From: Brodie Date: Tue, 11 Aug 2026 02:06:20 -0400 Subject: [PATCH 1/4] Add improvement plan (baseline ad2bdc3) P0 correctness fixes through P3 doctrine polish, sequenced as v4.0.1 / v4.1.0 / v4.1.x.

The problems are almost all mechanical: one +load-bearing bug in how the codex lane's shell steps are written, a handful of +contract gaps between what one file promises and another file handles, and +release hygiene that has already drifted (the shipped `4.0.0` and the tagged +`v4.0.0` differ in model, effort, and prompt preamble). Plan is ordered by +severity; each item names the problem, the change, and how to know it's done. + +--- + +## P0 — Correctness bugs (ship as v4.0.1) + +### 1. Codex invocation breaks across Bash calls +**Problem.** `agents/codex-implementer.md` presents step 1 (write `$SPEC`/`$FINAL` +via `mktemp`) and step 2 (the `codex exec` invocation) as separate fenced +blocks. Claude Code runs each Bash tool call in a fresh shell — env vars don't +persist. An agent that follows the file literally runs step 2 in a shell where +`$SPEC` and `$FINAL` are unset: the `- < "$SPEC"` redirect fails loudly ("No +such file or directory"), and even after the agent recovers by re-running both +blocks together, step 3 in yet another fresh shell can't re-read `$FINAL`. The +failure is loud, but it sits on the plugin's core path and every run trips it. + +**Change.** Merge steps 1–2 into one fenced block presented as a single Bash +invocation, and state the constraint explicitly: "Steps 1–2 are ONE Bash call — +shell state does not survive between tool calls." Step 3 (verification) can stay +separate but must re-derive `$FINAL` — simplest fix: have the single block +`echo "FINAL=$FINAL"` so the wrapper can carry the path forward, or `cat "$FINAL"` +at the end of the same block. + +**Done when.** The file contains no variable defined in one block and consumed +in another. + +### 2. Preflight can't detect a missing login +**Problem.** The file promises "installed and authenticated" preflight, but +`command -v codex && codex --version` only proves installation. The *mapping* +of auth failures to `STATUS: unavailable` is already documented (lines 21–28 +cover both cases) — the gap is *detection*: nothing in preflight probes login +state, so a logged-out CLI is only discovered mid-run at `exec` time. That +failure is loud, which makes this the least severe P0 — fine to let it slip to +v4.1.0. + +**Change.** Add an auth probe to preflight (`codex login status` exits non-zero +when logged out — verify against the current CLI and pin the actual command) so +the lane reports `unavailable` before burning a run. + +**Done when.** Preflight detects a logged-out CLI without invoking `codex exec`. + +### 3. Refusal detection dies outside git repos +**Problem.** The flag table sells `--skip-git-repo-check` as "works outside git +repos", but the empty-diff refusal detector — which the file itself calls the +thing that "actually catches a refusal" — is `git diff`. Outside a repo that +command fails outright (fatal, exit 128), leaving the wrapper with no working +refusal check and no documented fallback. + +**Change.** Pick one: (a) require a git repo and drop the "works outside git +repos" claim, or (b) keep the flag and add a non-git fallback (snapshot +`find . -type f -newer "$SPEC"` after the run). Recommend (a) — simpler, and +Claude Code sessions are overwhelmingly in repos. + +**Done when.** The claim and the detection mechanism agree. + +### 4. `fable-advisor` is asked to read diffs it cannot obtain +**Problem.** The advisor's tools are `Read, Grep, Glob` — no Bash — yet its body +says "read the diff against the stated goal" and the skill says to "pass it the +diff". The only remaining channel is pasting the diff into the prompt, which the +skill's own cost doctrine forbids. + +**Change.** Define the handoff: the architect writes the diff to a file +(`git diff > /tmp/deliverable.diff` or a path under the session dir) and passes +the *path*; the advisor Reads it plus the touched files. Document this in both +`agents/fable-advisor.md` ("expect a diff path, not an inline diff") and +`skills/orchestration/SKILL.md`'s review section. Alternative — granting the +advisor Bash — is worse: it weakens the "advises only, never implements" wall. + +**Done when.** Both files describe the same diff-path handoff. + +### 5. Lane racing corrupts the working tree +**Problem.** README and SKILL.md recommend racing `codex-implementer` and +`fable-implementer` on the same spec — two agents writing the same files in the +same tree, two sentences after the parallelism rule requires "no shared files". + +**Change.** Require isolation for races: each racer runs in its own git worktree +(Claude Code's Agent tool supports worktree isolation; codex gets `--cd` pointed +at a worktree). Architect diffs the two worktrees and picks. If that's judged +too heavy, delete the racing recommendation instead — as written it's a footgun. + +**Done when.** Racing is either isolated or gone from both files. + +--- + +## P1 — Contract gaps (v4.1.0) + +### 6. Unify the status vocabulary and complete the failure routing +`codex-implementer` returns `complete|partial|timeout|unavailable|refused`; +`fable-implementer` returns `complete|partial|blocked`. SKILL.md routes only +`unavailable|timeout`. Nothing tells the architect what to do with `refused`, +`partial`, or `blocked` — including the AGENTS.md-refusal mode the plugin went +to great lengths to detect. Define one shared status enum in SKILL.md with an +architect action per status (e.g. `refused` → prepend/adjust preamble once, then +escalate; `partial` → corrected spec with the gap named; `blocked` → architect +decision). Add `REASON:` to the standard report schema (today it appears only in +the preflight example, though a rule requires it for `refused`). + +### 7. Document timeout detection +The wrapper is told to "report `STATUS: timeout`" but not how to know: state +that `timeout`/`gtimeout` exits 124, and that 124 ⇒ `STATUS: timeout` with +whatever landed in the diff. + +### 8. Temp-file hygiene +Add cleanup to the single merged block (`trap 'rm -f "$SPEC" "$FINAL"' EXIT` — +after `$FINAL` is read) and use a `mktemp` form that behaves the same on GNU and +BSD (`mktemp "${TMPDIR:-/tmp}/codex-spec.XXXXXX"`), since the file already cares +about macOS portability for `timeout`. + +--- + +## P2 — Maintainability and release hygiene (v4.1.0) + +### 9. Centralize the model pins +The literal slug `gpt-5.6-luna` appears 4 times across 2 files (README plus +three sites in `codex-implementer.md`); counting prose forms ("GPT-5.6 Luna"), +the model is named in ~13 sites across 5 files — plus `model: fable` ×2 and +`model: sonnet` ×1 in agent frontmatter. Every repin so far (three in four +weeks) touched most of them. Full centralization isn't possible in a prompt-only +plugin, but two moves cut the surface: +- Make `agents/codex-implementer.md` the *only* place the codex slug and effort + appear normatively; README/SKILL/manifests say "the codex lane's pinned + model — see codex-implementer.md" instead of naming it. +- Honor an env-var override (`FABLE_ADVISOR_CODEX_MODEL`, read in the merged + Bash block: `--model "${FABLE_ADVISOR_CODEX_MODEL:-gpt-5.6-luna}"`) so users + can repin without editing files that `claude plugin update` will overwrite — + the README already flags that exact failure for Claude pins via + `CLAUDE_CODE_SUBAGENT_MODEL`; this is the codex-side equivalent. + +### 10. Release hygiene +- Bump to 4.0.1/4.1.0 with the P0/P1 fixes — HEAD already differs from the + v4.0.0 tag in model, effort, and preamble with no bump; that's the defect to + stop repeating. +- Add `CHANGELOG.md` (backfill from the 11 commit subjects; note untagged + v1/v2/v2.1/v3/v3.1 SHAs so references like the README's "v3.1 tree" link + resolve to something named). +- Tag every release going forward; retro-tag `b3b50a9` as `v3.1` so the README + link is honest. + +### 11. CI that would have caught the drift that already happened +Add one GitHub Actions workflow (no tests exist; the AGENTS.md refusal was +found in production): +- JSON validity for both manifests; frontmatter presence/shape for all agents + (`name`, `model`, `tools`, `description`). +- Consistency greps: version in `plugin.json` == latest `CHANGELOG.md` entry; + the codex model slug appears only in its one normative site (per item 9); + no variable defined in one fenced block and consumed in another (per item 1 — + a ~10-line script can lint this). +- Optional smoke job (manual trigger): preflight against a real codex install. + +### 12. Manifest completeness +`marketplace.json` has no version, license, keywords, or category on the plugin +entry, and its two descriptions drift independently from `plugin.json`'s. Add +the missing fields and reduce the three hand-maintained blurbs to one canonical +sentence reused verbatim. + +--- + +## P3 — Doctrine polish (v4.1.x, docs-only) + +### 13. Resolve "never type code" vs "keep that piece with the architect" +The CLAUDE.md snippet says never; SKILL.md line 30 offers "keep that piece with +the architect" as a routing outcome. Pick the real rule — suggested: the +architect may type only when a spec would be longer than the diff, and must say +so in its report — and state it identically in both places. + +### 14. Reconcile cost discipline with verification duty +"Keep the context lean" and "independently re-run verification / read the diff" +pull opposite directions. State the intended balance: the *wrapper lanes* read +full diffs and quote evidence; the *architect* reads reports and spot-checks, +entering full diffs into its context only at commitment boundaries (where the +advisor gets the diff path anyway, per item 4). + +### 15. README accuracy pass +- "Change `model: fable` → `model: opus` in the advisor and implementer files" + — only two of three agents pin `fable`; name the two files exactly. +- Warn that a globally-set `CLAUDE_CODE_SUBAGENT_MODEL` outranks every + frontmatter pin in the plugin (the README documents the precedence order but + not this consequence). +- Note the honest cost accounting: the codex lane's wrapper is a Sonnet agent + burning Claude tokens on preflight/supervision/re-verification; "never falls + back to a Claude model" is true of the work, not the babysitter. +- Move "Observed live 2026-08-04" and "Luna supports low/medium/high/xhigh/max; + there is no `ultra`" from prompt text into CHANGELOG/README where dated claims + belong; prompts should carry rules, not perishable facts. + +--- + +## Suggested sequencing + +1. **v4.0.1** — items 1–5 (correctness) + tag + CHANGELOG started. Small diffs, + all in `agents/*.md` + SKILL.md; highest payoff per line. +2. **v4.1.0** — items 6–12 (contracts, pins, CI, manifests). +3. **v4.1.x** — items 13–15 (docs-only polish), safe to trickle. + +Items 1, 4, 5, and 6 change agent behavior and deserve a live smoke test with a +real codex install before tagging.
