policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #494
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. 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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe JavaScript tooling policy replaces Deno with Bun. It updates approved runtime guidance, banned-runtime mappings, manifest and lockfile requirements, production installation, and pinned tooling commands. ChangesBun tooling policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to The policy now directs agents toward Bun and away from Deno, but template guidance still contains Deno/ReScript build and development examples, which can produce contradictory project instructions. This is a bounded documentation issue, so the PR is mergeable with explicit owner follow-up to update the examples or document the exception. Poem

Pull Request Overview
The PR successfully promotes Bun to Tier 1 and removes Deno as intended. Codacy analysis indicates the changes are up to standards with no new quality issues.
However, there is a significant gap: the PR description mentions restoring 'ReScript' terminology to fix 'blanking scars,' but the diff does not contain these specific changes. Additionally, two minor clarity issues were identified in the policy wording that could lead to inconsistent AI behavior regarding language selection and rule application.
About this PR
- The PR description and acceptance criteria claim to restore 'ReScript' terminology to address previous 'blanking scars' (e.g., changing 'No new files' to 'No new ReScript files' and updating the BANNED table), but these changes are absent from the current diff. Please verify if these updates were intended for this pull request.
Test suggestions
- Verify Bun is listed as the Tier 1 tool in the ALLOWED table
- Verify Deno is replaced by Bun in the BANNED table replacements
- Verify Enforcement Rules mandate the use of package.json and bun.lock
- Missing the restoration of 'ReScript' terminology in Rule 1 and the BANNED table as specified in the description

⚪ LOW RISK
Suggestion: The mention of 'no build step' for .ts files might lead the AI to favor TypeScript over AffineScript (which requires a build step) for convenience. Consider clarifying that Bun is the runtime for the compiled output of AffineScript.

⚪ LOW RISK
Nitpick: Rephrase this rule to be declarative for consistency with the other enforcement rules (e.g., 'Production dependencies must be installed using the --production flag').
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. 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). 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).

Align the skeleton policy with the Bun-first runtime policy.
robot-repo-automaton/templates/skeleton/.gitignore still states Deno>Bun>pnpm>npm, which conflicts with the Bun replacements in robot-repo-automaton/.claude/CLAUDE.md. Update the template comment or document why it intentionally remains Deno-first.

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.
Mirrors the TypeScript row's own replacement cell rather than assuming the literal string, so bold, qualified and extra-column table variants are all handled without reformatting the surrounding table. Enforcement Rule 1 is untouched: standards#655 records that collision as not resolvable unilaterally. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
