policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #61
Conversation
Owner ruling 2026-08-26: "deno is to go and bun is the way we are going, put it
first everywhere unless not possible and explain why if not".
This file is what an agent reads FIRST and it listed Bun as BANNED with Deno as
its replacement. Correcting hyperpolymath/standards (#655) fixes one copy of
~372 - agents read the local one. This is that local copy.
ALLOWED **Deno** "Replaces Node/npm/bun" -> **Bun** tier 1
BANNED | Bun | Deno | -> row REMOVED
BANNED Node.js / npm / pnpm/yarn -> Deno -> -> Bun
rule "No package.json for runtime deps - use deno.json imports"
-> Use package.json + bun.lock; a manifest is REQUIRED
rule "No node_modules in production"
-> bun install --production, pinned via bun.lock
pkg JS deps: Deno -> JS deps: Bun (package.json + bun.lock), bunx
WHY THE MANIFEST RULE MATTERS MOST. "No package.json for runtime deps" did not
express a preference - it told repos not to declare their dependencies at all.
hyperpolymath/ubicity imported zod and glob, shipped NO manifest of any kind,
and could not build under ANY toolchain. Fixed in ubicity#107; the rule that
caused it is fixed here.
ALSO REPAIRED - blanking scars from the ReScript purge, which substituted the
token with an EMPTY STRING rather than removing the text:
| | AffineScript | -> | ReScript | AffineScript |
1. **No new files** ... -> **No new ReScript files** ...
| **JavaScript** | Only where cannot | -> Only where AffineScript cannot
Restoring the NAME in a policy table does not reintroduce the language. Same
root cause as the rm -rf /lib found in wordpress-tools#62.
Policy text only - no code, no workflows, no build files. 3 file(s).
NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per
ADR-2026-STACK-MIGRATION) but that is a separate ruling; flagged, not changed.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe assistant instructions for three project templates now replace Deno with Bun. They update runtime selection, banned tools, dependency manifests, production installation, and one-off tooling guidance. ChangesBun policy migration
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR correctly makes Bun the default, but its current guidance could allow undeclared or Node-backed tools through bunx and could cause projects needing production bundles to skip a required build step. This is a bounded documentation risk and is mergeable with explicit owner follow-up. Poem

Pull Request Overview
The pull request effectively promotes Bun to the Tier 1 JS/TS runtime across the project's documentation, establishing strict requirements for package management and production installation. While the implementation of the Bun policy is solid, there is a significant alignment gap: the PR description mentions repairing 'blanking scars from the ReScript purge,' but no ReScript-related updates appear in the changed files. Furthermore, although Deno has been removed from the allowed list, it should be explicitly listed in the banned tools table to prevent AI agents from reverting to Deno-based patterns. Codacy analysis indicates the changes are up to standards with no quality or complexity issues.
About this PR
- The implementation does not reflect the stated intent to restore ReScript-related text. The files still exclusively reference TypeScript and lack the 'ReScript' keyword or the specific rule updates mentioned in the PR description.
Test suggestions
- Verify Bun is listed as Tier 1 in the Allowed Languages table across all files
- Verify Node.js, npm, and pnpm/yarn are mapped to Bun in the Banned table
- Verify Enforcement Rules 2 and 3 mandate manifests and production install flags
- Verify restoration of ReScript mentions in Banned table and Rule 1 as described
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify restoration of ReScript mentions in Banned table and Rule 1 as described

Suggestion: Since Deno is being phased out in favor of Bun, explicitly add it to the Banned table to provide clear direction for AI agents.

Review feedback from codacy-production and coderabbitai on the policy wave. Three substantive points, all accepted: 1. ".ts CONTRADICTION" (codacy, MEDIUM, raised on most of the wave). The Bun row said "Executes .ts directly, no build step" in a file whose BANNED table bans TypeScript. True of Bun, but it reads as licence to write new TypeScript. Reworded to compiled ESM/JS, with an explicit note that Bun's native .ts support does NOT license new TypeScript. 2. "DENO MISSING FROM BANNED" (codacy, raised repeatedly). The wave removed Deno from ALLOWED but never added it to BANNED, so the ruling was only half expressed. Added | Deno | Bun |. 3. "UNPINNED bunx" (coderabbitai, Security & Privacy). A bare `bunx <tool>` can fetch a package outside package.json/bun.lock, and can start Node via a shebang - both contrary to estate SHA-pinning doctrine and the Node ban. Guidance now requires a declared devDependency plus `bunx --no-install --bun <tool>`. NOT taken: "a npm-compatible" (LanguageTool is wrong, "an" is correct before a vowel sound); "--frozen-lockfile is redundant" (correct - no change needed, and none made); the Nix->Guix point (real, but a separate ruling, deliberately not folded into a Deno/Bun change).

All substantive review findings are addressed in the latest push.
Declined, with reasons: "a npm-compatible" — LanguageTool is wrong; "an" is correct before a vowel sound. " Dismissing the stale review on that basis; the original review, this reply, and the dismissal reason all remain on the PR. |
Addressed in the latest push; the preceding comment lists what was fixed and what was declined with reasons. Owner ruled TypeScript should not exist at all, so every .ts reference is gone from the Bun row; Deno added to BANNED; bunx now requires a declared devDependency plus --no-install --bun; description regenerated from the diff.
