policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #42
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe project guidance changes its JavaScript and TypeScript runtime policy from Deno to Bun. It updates allowed tools, banned-tool replacements, dependency lockfile requirements, production installation commands, and one-off tooling guidance. ChangesBun runtime and package management policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy update makes Bun the default but currently permits bunx usage that can bypass the declared lockfile and may invoke Node.js through tool shebangs, weakening dependency pinning and the stated runtime policy; the documentation should be tightened before merge.

Pull Request Overview
The PR successfully transitions the project policy to Bun as the Tier 1 runtime and package manager, correctly mandating package.json and bun.lock manifests. Analysis indicates that the code is up to standards according to Codacy.
However, there is a misalignment between the PR's stated intent and the implementation. The PR claims to repair 'blanking scars' from the ReScript purge, but the code still references a ban on TypeScript in Rule 1 and the BANNED table, rather than shifting those references to ReScript as described. Additionally, the description for Bun should be refined to prevent ambiguity regarding the project's ban on TypeScript files.
About this PR
- The implementation does not fully reflect the PR description regarding the ReScript purge. While the description mentions updating Rule 1 and the BANNED table to repair ReScript-related artifacts, the actual changes still reference TypeScript. Please ensure the implementation matches the 'repair' intent mentioned in the PR title.
Test suggestions
- Found recommended test scenario: Verify Bun is marked as Tier 1 and the default for new work in the ALLOWED table
- Found recommended test scenario: Verify Bun replaces Deno as the replacement for Node/npm/pnpm/yarn in the BANNED table
- Found recommended test scenario: Verify Enforcement Rules 2 and 3 mandate package.json and bun.lock
- Missing recommended test scenario: Verify Rule 1 is updated to 'No new ReScript files' per the PR description
- Missing recommended test scenario: Verify the BANNED table restored the 'ReScript' name to the AffineScript replacement row
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing recommended test scenario: Verify Rule 1 is updated to 'No new ReScript files' per the PR description
2. Missing recommended test scenario: Verify the BANNED table restored the 'ReScript' name to the AffineScript replacement row

🟡 MEDIUM RISK
Suggestion: The mention of direct .ts execution contradicts the ban on TypeScript in lines 40 and 62. To avoid AI confusion, focus the note on Bun's role in executing the compiled ESM/JS output.

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. 1 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.

so every bunx tool is declared in package.json and resolved through bun.lock,
and require the no-install bunx mode to prevent fetching undeclared packages.
Keep the existing bun install --production guidance intact.

Bun bunx documentation --bun Node shebang default behaviour
💡 Result:
By default, bunx respects the shebang line found in scripts or executable files [1][2]. If a file contains a Node.js shebang, such as #!/usr/bin/env node, bunx will automatically spawn a Node.js process to execute it [1][3]. To override this default behavior and force the executable to run using the Bun runtime instead, you must use the --bun flag [1][2]. It is important to place this flag before the name of the executable being run, as flags placed after the name are passed through to the executable itself [1][4]. Example usage: bunx --bun If you are the author of a script and want it to always run with Bun by default, you can update the shebang line to use #!/usr/bin/env bun [1][4].

Use bunx --bun <tool> for tools that must run with Bun.
bunx <tool> can honour a #!/usr/bin/env node shebang and start Node.js, which conflicts with the Node.js ban. Document bunx --bun <tool> and list any Node.js-only tools as explicit exceptions.

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).

The Bun row said "Executes .ts directly, no build step" in a file whose BANNED table bans TypeScript. OWNER RULING: TypeScript "should not exist at all", so advertising Bun's TypeScript capability is wrong regardless of whether it is true. Every .ts reference is removed from the row, including "JS/TS" in its label. 2. "DENO MISSING FROM BANNED" (codacy, raised repeatedly).

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.
