policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #62
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 Claude policy document changes JavaScript and TypeScript guidance from Deno to Bun. It updates allowed and banned tools, enforcement rules, package management, and one-off tooling instructions. ChangesBun runtime policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy now bans runtimes and package managers that the repository still requires for setup and development, so agents following it may be unable to use the documented workflow. Align those repository commands with Bun or document an explicit exception before merging. Suggested reviewers: Poem

Pull Request Overview
While Codacy analysis indicates the PR is generally up to standards, the transition to Bun as the Tier 1 JavaScript runtime contains a critical technical error and an implementation gap. The .claude/CLAUDE.md file contains unresolved Git conflict markers that render the policy file malformed and potentially unparseable for AI agents. Additionally, there is a discrepancy between the PR description and the actual changes, as the restoration of 'ReScript' references corrupted in previous updates is absent from the diff. These issues should be addressed to ensure policy integrity and alignment with the PR requirements.
About this PR
- The file .claude/CLAUDE.md contains unresolved Git conflict markers (lines 67-71). These markers are visible to AI agents and may cause parsing errors or logic conflicts when tools attempt to process the repository rules.
- The PR description specifies that 'ReScript' references should be restored in the Banned table and Rule 1 where they were previously blanked out, but these changes are not present in the current diff.
Test suggestions
- Verify Bun is listed as Tier 1 with explicit manifest requirements\n- [ ] Verify ReScript/TypeScript conversion rules are updated per the PR description\n- [ ] Verify Git conflict markers are resolved in the Enforcement Rules section

45-47: LGTM!
81-81: LGTM!
27-33: 🎯 Functional CorrectnessNo Deno exemption is needed for this policy.
The policy makes Bun the default for new work. It does not ban Deno or require existing Deno commands in
gossamer.conf.jsonandJustfileto change.
`.claude/CLAUDE.md` carried literal conflict markers on the branch:
<<<<<<< HEAD
2. **Use `package.json` + `bun.lock` for JS runtime deps** - ...
=======
2. **Use `package.json` + `bun.lock` for JS runtime deps** - ...
>>>>>>> d50974d (chore: global textual eradication of Nix and ReScript)
BOTH SIDES WERE BYTE-IDENTICAL. The textual-eradication pass produced a
spurious conflict — nothing actually diverged — and the markers were committed
with it, leaving enforcement rule 2 duplicated and rules 3-6 buried below a
`>>>>>>>` line.
This matters more than a normal conflict-marker slip because the file is an
AGENT INSTRUCTION DOCUMENT. It does not break a build; it silently feeds
malformed, self-duplicating policy to every AI agent that reads the repo. Both
Codacy and CodeRabbit flagged it, and it was the only HIGH RISK finding among
303 unresolved review threads across ~90 fleet PRs.
Resolved by collapsing the block, after asserting programmatically that the two
sides were identical — so a genuine divergence would have failed loudly rather
than being silently decided.
Verified: 0 conflict markers remain in the file and none elsewhere in the repo;
enforcement rules read 1-6 with no duplication.

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).

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.
Addresses the two live static-analysis findings on this PR. ReScript was absent from the BANNED table although canon bans it (destination AffineScript), so the table read as permitting it. Enforcement Rule 3 said `bun install --production` with no `--frozen-lockfile`, so a lockfile mismatch silently re-resolved instead of failing, which defeats the point of committing `bun.lock`. Enforcement Rule 1 is deliberately untouched: standards#655 records that collision as not resolvable unilaterally. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Align the enforced runtime with the repository setup commands.
This policy bans Deno, Node.js, npm, pnpm, and yarn, and requires Bun. However, Justfile still requires deno for setup and runs deno task dev. mise.toml also provisions the banned runtimes and package managers. An agent that follows this policy may be unable to run the documented setup or development workflow.
Before merging, update those repository contracts to Bun, or document an explicit exception for the existing Deno workflow.
