fix(onboard): validate Slack bot token format before saving by latenighthackathon · Pull Request #2130 · NVIDIA/NemoClaw

latenighthackathon · 2026-04-21T01:40:04Z

Summary

The interactive setup wizard accepted any string as a Slack Bot Token — including the example abcd from the bug report — and continued to sandbox creation. The invalid token then surfaced as a cryptic auth failure only after the sandbox was built.

This PR adds a minimal format check at the prompt point.

Related Issue

Closes #1912

Changes

Add tokenFormat regex (^xoxb-[A-Za-z0-9-]+$) and tokenFormatHint to the slack entry in MESSAGING_CHANNELS so the validation rule travels with the channel definition. Future channels can opt in by adding the same fields.
In setupMessagingChannels' interactive prompt loop, reject tokens that do not match tokenFormat: print a one-line hint (Slack bot tokens start with 'xoxb-'...) and drop the channel from the enabled set, mirroring the existing "no token entered" skip path.
Non-interactive mode is intentionally unchanged — env-var credentials are assumed to be intentional.
Export MESSAGING_CHANNELS so the regex is directly unit-testable.

Testing

npx vitest run test/onboard.test.ts — 130 tests pass
New regression test verifies the regex rejects the bug-report value (abcd), empty strings, user tokens (xoxp-...), app tokens (xapp-...), leading prefixes (Bearer xoxb-...), and whitespace-bearing tokens while accepting valid xoxb-... forms
Build + typecheck clean (npm run build:cli, npm run typecheck:cli)

📝 Walkthrough

Walkthrough

Onboarding now validates per-channel token formats: tokens are checked against channel tokenFormat during interactive setup; invalid tokens are rejected, the channel is disabled for that run, and credentials are not saved. MESSAGING_CHANNELS is exported from src/lib/onboard.ts. Tests for Slack token validation were added.

Changes

Cohort / File(s)	Summary
Onboard + export & validation `src/lib/onboard.ts`	Exports `MESSAGING_CHANNELS` via `module.exports`. During interactive messaging setup, tokens are validated against any channel `tokenFormat`; invalid tokens produce a console warning, the channel is removed from enabled set, and credential saving is skipped.
Channel definitions `src/lib/sandbox-channels.ts`	`ChannelDef` gains optional `tokenFormat?: RegExp` and `tokenFormatHint?: string`. `KNOWN_CHANNELS.slack` now includes a `tokenFormat` (enforces `xoxb-...`) and a `tokenFormatHint`.
Tests for Slack token format `test/onboard.test.ts`	Adds Vitest tests that simulate interactive setup, assert invalid Slack tokens are rejected and not persisted, expect an “Invalid format” warning, and verify the Slack `tokenFormat`/hint accept valid `xoxb-...` examples and reject invalid ones.

Poem

🐰 I nibble at strings and sniff for "xoxb-",
I hop through prompts until the tokens obey,
If gibberish tries to sneak, I stamp my paw,
No saved crumbs of nonsense in my tidy lair,
Hooray — clean channels and tests today!

PR Review: fix/slack-token-validation

Files Changed: 3
Lines: +53 / -0

🔴 Blocker (must fix before merge)

Missing runtime validation logic — The PR description states that setupMessagingChannels() rejects tokens that do not match tokenFormat, but this code does not exist. The tokenFormat and tokenFormatHint fields are added to the Slack channel definition and tested in isolation, but setupMessagingChannels() in onboard.ts never reads ch.tokenFormat or ch.tokenFormatHint. The token prompt flow accepts any non-empty string, saves it via saveCredential, and proceeds.

The bug (#1912) is not fixed. A user can still type abcd as a Slack bot token and it will be saved.

Suggested fix — add a format check in the prompt loop (around line 5140 of src/lib/onboard.ts), after the prompt and before saveCredential:

const token = normalizeCredentialValue(await prompt(`  ${ch.label}: `, { secret: true }));
if (token) {
  // Validate token format when the channel defines one
  if (ch.tokenFormat && !ch.tokenFormat.test(token)) {
    console.log(`  ✗ Invalid format. ${ch.tokenFormatHint || 'Check the token and try again.'}`);
    console.log(`  Skipped ${ch.name} (invalid token format)`);
    enabled.delete(ch.name);
    continue;
  }
  saveCredential(ch.envKey, token);
  process.env[ch.envKey] = token;
  console.log(`  ✓ ${ch.name} token saved`);
}

🟡 Warnings (should fix)

Regex character class may be too restrictive (sandbox-channels.ts:61) — The regex ^xoxb-[A-Za-z0-9-]+$ only allows alphanumerics and hyphens. Real-world Slack tokens can contain underscores. Consider widening to ^xoxb-[A-Za-z0-9_-]+$ to avoid rejecting legitimate tokens. False negatives (rejecting valid tokens) are worse than false positives for a format hint check.
Branch was 69 commits behind main — I rebased it for you. No conflicts.

🔵 Suggestions (nice to have)

Once the runtime logic is added, consider adding a behavioral test that mocks prompt() to return "abcd" and verifies the channel is dropped from the enabled set and saveCredential is not called.
Consider validating the app token (xapp- prefix) too — if tokenFormat is a general mechanism, the app token prompt could benefit from the same treatment.

✅ What's Good

Clean, scoped commit with good conventional commit message and DCO sign-off
Extensible design — tokenFormat/tokenFormatHint on ChannelDef is the right abstraction for future channels
Comprehensive regex test coverage with good edge cases
Non-interactive path intentionally excluded — correct for env-var credentials

…n test Replaces the CommonJS `delete require.cache[onboardPath]` + `require(onboardPath)` pair with `await import(\`${pathToFileURL(onboardPath).href}?update=\${Date.now()}\`)` so the test reloads `dist/lib/onboard.js` through the ESM loader (require.cache has no effect on ESM modules in this file).

Thanks for the feedback @jyaunches, addressed the blocker (wired ch.tokenFormat into setupMessagingChannels), widened the regex for underscores, and added an interactive integration test for the invalid-token path - Cheers!

@jyaunches

Parallels the bot-token check: adds appTokenFormat / appTokenFormatHint to ChannelDef, pins Slack's app token to ^xapp-[A-Za-z0-9_-]+$, and wires the check into setupMessagingChannels so a bogus xapp- prompt drops the channel from the enabled set and skips saveCredential for SLACK_APP_TOKEN. Note: if the bot token passes but the app token fails, the bot token stays persisted (it was already saved before the app-token prompt). That's acceptable — on a retry onboard the bot token lights up as "already configured" and only the app-token prompt fires again. Extends the existing regex test with xapp- valid/invalid cases and adds a second interactive integration test covering the bot-valid + app-invalid path. Per @jyaunches suggestion #2 on NVIDIA#2130.

…1912) Wires ch.tokenFormat into setupMessagingChannels so bogus tokens like "abcd" are rejected at the prompt instead of silently saved. When the entered value doesn't match the channel's tokenFormat regex, the channel is dropped from the enabled set with the configured hint and the loop continues. Also widens the Slack bot-token regex from [A-Za-z0-9-]+ to [A-Za-z0-9_-]+ so legitimate tokens containing underscores aren't falsely rejected. Adds an interactive integration test that mocks credentials.prompt to return "abcd", drives the toggle UI via piped stdin, and asserts slack is dropped from the enabled set and SLACK_BOT_TOKEN is never persisted. Extends the existing regex test with underscore cases to lock in the widened character class. Signed-off-by: latenighthackathon <latenighthackathon@users.noreply.github.com>

PR Review: fix/slack-token-validation (Round 2)

All Round 1 findings addressed — nice work @latenighthackathon.

✅ Verified

Blocker resolved — ch.tokenFormat is now wired into setupMessagingChannels() (line 5416). Format check runs before saveCredential, so invalid tokens are never persisted.
Regex widened — [A-Za-z0-9_-]+ now accepts underscores.
App token validation added — appTokenFormat/appTokenFormatHint mirrors the bot token pattern. Consistent.
Behavioral tests pass — 3 new tests verify both the regex and the interactive prompt rejection flow (mocked prompt(), piped stdin, outcome-based assertions).

🟡 Notes (non-blocking)

"Already configured" path bypasses format validation — if a malformed token was saved before this fix, re-onboard skips straight to "✓ already configured" without re-checking format. Acceptable — credential migration is a separate concern.
1 commit behind main — trivial rebase for 660c7afc (refactor types). No conflicts.

Recommendation

Approve. Squash-merge recommended to collapse the 4 commits into one clean entry.
