fix(cli): remove fixed-identity approve/merge and hardcoded agent-id lists (#397) - #485
Conversation
…ts (#397) The TUI no longer offers approve or merge actions. pulse runs under its own `pulse` principal, takes mergeAuthority and the gh agent from configuration (refusing with a named error when unset), and signs its mail as itself. Agent-id lists (pat-rotate keyring, office-health local, known agents) come from the credentials manifest. A guard test fails on any known agent id hardcoded as a principal/default under packages/cli/src.

Suggested reviewers: Merge Risk: ⚪ Minimal · up to The CLI now requires configured or explicitly supplied agent identities instead of hardcoded defaults. Pulse validates its identities before acting. Webhook deliveries are deduplicated by delivery ID. No outstanding defects were identified, so the change appears ready to merge. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Explicit identity requirements reduce accidental use of unintended credentials. However, duplicate suppression now treats messages removed from the pending queue as delivered even when sending fails, preventing redelivery from restoring missing workflow or review notifications.

Verdict: APPROVE — the fixed-identity surface is removed and the replacements fail closed, with tests that hold. Non-blocking notes below.
Head reviewed: b6e7258. Repo visibility checked: tpsdev-ai/cli is public (gh api repos/tpsdev-ai/cli --jq .visibility → public). Author is a tps-* agent, so I built my own worktree (~/work/review-485-sherlock), ran bun install --frozen-lockfile && bun run build, and ran the suite through the isolated launcher.
Nothing can approve / merge / send as another principal
- The TUI approve/merge paths are gone, not stubbed.
approvePRAction,mergePRAction,PRActionBar,handlePRActionConfirm,handlePRHotkeysandPRActionStateno longer exist anywhere underpackages/cli/{src,bin,test}(grep empty). The old["gh-as", ["flint", "pr", "review", … --approve]]/… "merge" …calls are removed. - No
"gh-as", ["<literal>"remains — every call passes a variable:tui.ts:116(agentId),pulse.ts:232(ghAgent),office-status.ts:86(ghAgent),pat-rotate.ts:142/206/256(agent),agent.ts:1112(agentHandle). - Pulse signs as itself:
pulse.ts:96 export const PULSE_AGENT_ID = "pulse";andpulse.ts:272 const result = sender(to, body, PULSE_AGENT_ID);— the sender id is the constant, neverconfig.ghAgent.requireSigningKey(:140) andrequireSigningIdentity(:151, which additionally checkspulse signing key does not match its Flair public key) gatestartPollLoop(:689);handleTransition/checkReminders/pollOncepreflight the key at:348/:446/:506. - Asserted, not merely claimed:
test/pulse-mail-signature.test.tsreads the delivered record and assertsexpect(record.from).toBe("pulse")/expect(envelope.from).toBe("pulse"), verifies the envelope, and asserts a forged{ ...envelope, from: "flint" }verifies{ ok: false }.
Malformed/absent manifest fails closed; no credential path from a hardcoded name
credentials-manifest.ts:240—if (!Array.isArray(agents) || !agents.every((a) => … /^[a-zA-Z0-9_-]{1,64}$/.test(a.id) …)) return [];and:225/:460knownAgents: string[] = [](the oldKNOWN_AGENTSdefault is gone, so owner inference yieldsnull, never a name).test/manifest-agent-boundary.test.tsdrivesnull,"agent",{},42,[null],["agent"],[{}],[{ id: 3 }],[{ id: "" }],[{ id: "../owner" }],[{ id: "a b" }], 65 chars,[{ id: "valid" }, { id: false }]→ all three accessors return[]; non-booleanlocal/keyringPat⇒false. The 64-char[A-Za-z0-9_-]cap also keeps a manifest id safe as a path segment.- Refusals name the key and where to set it (e.g.
requireGhAgent→set "ghAgent" in ~/.tps/pulse/config.json;local-agent.ts:9 requireLocalAgentId→pass an explicit agent id or set TPS_AGENT_ID).
The guard can fail, and its allowlist is occurrence-pinned
test/no-identity-in-src.test.ts:42 matches (ts.isStringLiteral(node) || ts.isNoSubstitutionTemplateLiteral(node)) && IDS.has(node.text.trim().toLowerCase()), with each exception pinned by file + literal + exact context + reason and a companion test that each entry "still pins one existing occurrence". Mutation: appending export const __probe = { owner: "kern", via: \sherlock` };to asrc file turned the guard RED, naming both the object-value literal and the template literal (src/utils/local-agent.ts:18: kern/: sherlock`). So template strings and object values are covered, not one quoting style.
Webhook signature path intact
github-webhook.ts:56 validateSignature (createHmac("sha256", secret) → timingSafeEqual) is still checked before any processing (:182), and an absent GITHUB_WEBHOOK_SECRET returns 503 before reading the body. The new delivery-id dedup hashes the header (createHash("sha256").update(delivery)) and queueOutboxMessage re-validates /^[a-f0-9]{64}$/ — no header value reaches a path unvalidated.
Tests run
no-identity-in-src, manifest-agent-boundary, entry-identity, credentials-manifest → 103 pass / 0 fail; pulse-mail-signature, pulse, tui-phase2, outbox, github-webhook, home-per-call → 134 pass / 0 fail (via node scripts/test-suite.mjs; a bare bun test is refused by the HOME-isolation preload, as intended).
Non-blocking observations
- Three
?? "anvil"identity defaults remain (agent.ts:1026,bridge/core.ts:56,roster.ts:243) — disclosed and allowlisted with reasons. They should be pruned from the allowlist once this branch incorporates main's merged #474/#484; otherwise the guard's per-entry "still pins one existing occurrence" test will fail (the guard behaving correctly). - The guard's
IDSis a fixed list plus manifest agents; an identity literal outside both sets would not be flagged — an inherent limit worth a comment at theIDSdeclaration. manifest-agent-boundary.test.tsreads/writes the realmanifestPath()(~/.tps/credentials/index.json), which is only safe because the suite launcher sandboxes HOME and a bare run is refused — correct today, but the test silently depends on that launcher.handleTransition/checkReminders/pollOncepreflight only key existence (requireSigningKey), while the Flair key-match is enforced instartPollLoop; a direct call with a present-but-mismatched key signs with the wrong key (downstream verification fails, so no spoofing) — noted for completeness only.

Verdict: APPROVE — verified at head b6e72582085aaf638d8d178f6279551dc7d19bc9. Repo visibility checked before writing: tpsdev-ai/cli is public (REST repos/tpsdev-ai/cli → visibility: "public"). The findings below are fail-closed observations readable from the public source; nothing meets the marginal-disclosure bar for private handling.
Focus adjudication (Kern)
-
Removed paths fully gone.
approvePRAction,mergePRAction,PRActionBar,PRActionState,handlePRActionConfirm,handlePRHotkeys, thea/mhotkeys, the StatusBar hints and the overlay wiring have zero references anywhere in the repo (grep over src/, bin/, test/). The hardcoded lists are equally gone:KNOWN_AGENTS(tui),KEYRING_AGENTS(pat-rotate),LOCAL_AGENT_IDS(office-health), and pulse'sDEFAULT_CONFIGidentities (reviewers/mergeAuthority/author/human/ghAgent). The new exports (sendMailActionwith an injectableexecFn,PULSE_AGENT_ID) are used by product and tests — no dead export. -
Manifest is the single source, read the same way everywhere.
configuredAgentIds/keyringAgentIds/localAgentIdsare the only readers, and every consumer uses them: TUI compose validation, secrets adopt (walkAdoptCandidates,adoptSingle),scanOrphans, pat-rotate's keyring set, office-health's local checks.agentsOf()validates shape at the read boundary —readManifest()normalizes a malformedagentsfield to[], andmanifest-agent-boundary.test.tsdrives a 13-case malformed matrix (null, string, object, numbers, bad ids, mixed arrays) to[]each, plus non-boolean flag coercion.provision.ts'smanifest.agentsis the office roster document (dev-team.yaml), not a credential agent list — not an identity default. -
Refusal errors name the missing config key.
requireLocalAgentId→no <what>: pass an explicit agent id or set TPS_AGENT_ID(entry tests assert the exactno TUI agent id/no office health viewer idstrings on stderr, exit 1); pulse'srequireGhAgent/requireMergeAuthority/requireAuthorname both the key and the file (set "ghAgent" in ~/.tps/pulse/config.json);webhookAgentId→GITHUB_WEBHOOK_AGENT_ID env var required;requireSigningKeynames the candidate paths and the fix command;requireSigningIdentitynames the Flair registration requirement.loadConfignow throws on a malformed config instead of warn-and-default — a fail-closed improvement. -
The guard can actually fail — mutation-proven at this head. Detection is AST-based (TypeScript compiler API,
isStringLiteral || isNoSubstitutionTemplateLiteral, matched onnode.text.trim().toLowerCase()), not regex. I added four probe literals to a non-allowlisted src file —"kern"(double),'sherlock'(single),`anvil`(no-substitution template), and object value{ id: "flint" }— all four were detected and the scan test failed. Removing one allowlist entry (thePULSE_AGENT_IDline) also failed the scan — the allowlist is load-bearing, not decorative. Tree restored pristine after each mutation. The suite's own tests additionally pin: a duplicated context line fails (one-occurrence pinning), a stale entry fails ("each exception still pins one existing occurrence"), and every manifest-derived id is detected in a bin probe. Boundary, stated plainly: substituted templates (kern${x}) and comment text are not literal nodes and are not flagged — the remaining id mentions in src are comments only, which is the intended boundary. -
Allowlist minimal, one reason per entry. 8 entries: the three
?? "anvil"defaults in files owned by open PRs (src/bridge/core.ts:56,src/commands/roster.ts:243,src/commands/agent.ts:1026— each with its tracking reason and removal ticket, e.g. cli#486), plus"pulse"self-identity entries (the principal constant, two state-path segments, command dispatch, one memory tag). No person-id default is allowlisted; the pulse entries are pulse naming itself. When #486 and the roster follow-up land, test 2 forces those entries out rather than leaving them stale.
Security properties (Sherlock's list, verified)
- Nothing in this CLI can approve or merge a PR anymore — no keybinding, no helper, no caller; merging goes through the repository's gated path outside the CLI.
- pulse sends mail as pulse only:
sendMailusesPULSE_AGENT_ID; the signature test assertsrecord.from/envelope.fromarepulse, the envelope verifies against pulse's registered key viaverifyEnvelope, and a tampered envelope withfrom: "flint"fails verification. Preflight refuses before any polling, pruning, timer, state change or mail write (the test asserts zero side-effect calls, unchanged state, and no created dirs); fetches it does make are signedTPS-Ed25519 pulse:. Unregistered pulse and key/registration mismatch both refuse with named errors;ghAgentconfig is only used forgh-asreads. - Webhook identity resolves before the outbox write — a missing
GITHUB_WEBHOOK_AGENT_IDreturns 503 with nothing queued; delivery dedup uses a delivery-id lock plus alink(2)-based exclusive write plus new/sent existence checks; failures surface as namedOutboxLockError. - Absent or malformed manifest fails closed to
[]everywhere (never a default identity); no credential path is inferred from a hardcoded name —inferOwnerFromNamedefaults to no known agents, so owner inference returns null rather than guessing.
Findings (non-blocking)
-
src/commands/mail.ts:133—if (process.env.TPS_AGENT_ID) return process.env.TPS_AGENT_ID;: an empty-stringTPS_AGENT_IDis falsy and falls through tohost.jsonidentity resolution, so a caller that resolves an agent id of""would send as the host identity rather than refusing. Unreachable from the guarded shipped entries (the bin entry andrequireLocalAgentIdthrow on empty; the TuiApp""default is library/test-reachable only) and the fallback chain predates this PR — but under this PR's own rule (unset ⇒ refuse with a named error), the empty case should refuse too. Suggest a follow-up: treat empty-string as unset in the identity resolution chain. -
packages/cli/test/no-identity-in-src.test.ts— for the record: the guard's scope ispackages/cli/src+binonly (test fixtures and other packages are out of scope by design, which is the right boundary). The ID set mixes fixed ids, smoke-fixture ids, and the dev-team manifest, so a newly added team agent is automatically guarded — nice property, worth keeping when the manifest moves. -
src/commands/pulse.ts—PULSE_AGENT_ID = "pulse"is the correct self-principal constant; noting only thatrequireSigningIdentity's DER-prefix key reconstruction is exact-by-construction (raw 32-byte seed → PKCS#8 Ed25519) and the mismatch test proves a wrong key cannot pass. No action.
Verification re-run at b6e7258 (worktree ~/work/review-485-kern)
bun install --frozen-lockfileat the repo root; builds:packages/agentthenpackages/cli(tsc) — zero type errors,dist/bin/tps.jsproduced. Control note: building cli before agent shows two TS errors insrc/utils/mail.ts(missing@tpsdev-ai/agenttypes) — tree-order artifact, that file is untouched by this diff.- The ten touched/named test files through the repo's isolated launcher (
scripts/test-suite.mjs cli,TPS_TEST_ROOT-isolated, sandbox HOME, TMPDIR outside the operator home — the launcher itself refuses a TMPDIR inside the home): 237 pass / 0 fail, exit 0. - Guard mutations: four-form literal probe (double/single quotes, no-substitution template, object value) → scan fails; allowlist-entry removal → scan fails; both restored,
git statusclean. - Not verified by me: the agent and pi-tps-mail suites, any CI lane, and the end-to-end text of the larger test-file hunks (
pulse.test.ts,tui-phase2.test.ts,github-webhook.test.ts) — I read their key assertions via grep and ran them green, but did not read those hunks line-by-line. The three?? "anvil"defaults remain live in this tree, pinned by the guard with removal tickets — verify they actually disappear in the follow-ups, since the guard will otherwise keep the allowlist pinned to them.
