policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #74
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Pull Request Overview
The PR successfully promotes Bun to Tier 1 status and implements the mandatory use of package.json and bun.lock files. Codacy analysis indicates the changes are up to standards from a quality perspective.
However, there are notable gaps in the implementation. The PR description explicitly mentions repairing 'blanking scars' and restoring 'ReScript' text to Rule 1, yet the diff shows the rule still refers to TypeScript. Additionally, while Deno has been removed from the list of allowed tools, it has not been added to the Banned table. This omission may lead the AI assistant to suggest Deno in the absence of an explicit ban record.
About this PR
- The PR description claims to have repaired 'blanking scars' from a ReScript purge and specifically mentions changing Rule 1 to 'No new ReScript files'. However, the diff shows Rule 1 remains 'No new TypeScript files'. Furthermore, some of the BANNED table rows mentioned as requiring restoration already contained the text in the base version. Please verify if the ReScript-related changes were omitted by mistake.
Test suggestions
- Verify Bun is defined as the 'tier 1' default in the Language/Tool table.
- Verify the enforcement rules mandate a 'package.json' manifest for JS runtime dependencies.
- Verify Rule 3 is updated to specify production installation via 'bun install --production'.
- Verify the restoration of 'ReScript' text in Rule 1 ('No new ReScript files') as specified in the description.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify the restoration of 'ReScript' text in Rule 1 ('No new ReScript files') as specified in the description.

This line contradicts the PR description, which claims Rule 1 was updated to specify 'No new ReScript files'. It currently remains 'No new TypeScript files'.

🟡 MEDIUM RISK
Suggestion: Deno is being removed but is not listed in the Banned table. To ensure the AI assistant consistently avoids Deno and uses Bun instead, add Deno to the Banned list with Bun as its designated replacement. Prompt suggestion: '> Add Deno to the Banned table in .claude/CLAUDE.md with Bun as the replacement.'

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).
