T3 Code D

Best for Developers who want one app, including on their phone, to drive several coding agents they already pay for.

Also in its favour

  • No key needed to call it
  • No incidents deducted, where Paperclip loses 15 points for them

Watch for

Usage data on by default, with hashed OpenAI and Claude account identifiers, and relay traces to Axiom

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Security & auth Paperclip +29

Paperclip 64

Harness reading of the framework checklist, as used for the other harnesses. 30 for what leaves the machine by default, 20 for approvals and sandboxing, 15 for prompt-injection posture, 15 for audit and 20 for the security programme. Anonymous usage telemetry is on by default and goes to telemetry.paperclip.ing. The README lists what is excluded and four opt-outs, and Sentry and OpenTelemetry stay off until configured. We found no first-run notice in the CLI source (18). Board approvals for hires and strategy, execution policies and per-action connection permissions, but claude_local defaults dangerouslySkipPermissions to true, codex_local defaults to bypassing approvals and the sandbox, local agents run on the host, sandbox providers are optional plugins and the default local_trusted mode has no login (10). A documented low_trust_review preset contains agents that read untrusted pull requests or tickets. It is opt-in (10). An activity log of mutating actions, run logs, cost events and audited board API keys (14). SECURITY.md with GitHub private reporting and twelve advisories published per the 8 October check, three now with CVEs in OSV. No security.txt, bug bounty or SOC 2 report found (12).

T3 Code 35

Harness reading. Product usage events go by default to ingest.t3.codes and PostHog, with hashed identifiers for your T3 Connect, OpenAI and Claude accounts, and relay traces to Axiom, which can include machine names and error text. Off with T3CODE_TELEMETRY_ENABLED=false or a managed policy. Disclosed in docs/user/telemetry.md, not the README (10 of 30). Permission modes and managed policies (12 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 10 + 12 + 5 + 5 + 3 = 35.

Schema & documentation Paperclip +26

Paperclip 81

The running server publishes OpenAPI at /api/openapi.json and validates requests with Zod, and the MCP server's tools take Zod schemas. No copy of the spec is published on the docs site, and paperclip.ing/openapi.json describes only the website (22). llms.txt at paperclip.ing, and docs pages answer as Markdown at .md (10). An API reference page per resource and task guides, but the MCP tool descriptions are one line each, such as List agents in a company (13). Typed inputs throughout, apart from the paperclipApiRequest tool, which takes any path under /api and a JSON body (12). cURL, JavaScript and Python examples and a status-code table, with one {error} shape and an occasional details field (12). A changelog page for every stable release and release notes in the repository, but the API path carries no version (12).

T3 Code 55

Harness reading. User docs in the repository (managed policy, handoffs, providers, telemetry), AGENTS.md for contributors, a server other clients connect to (55).

Reliability Paperclip +16

Paperclip 59

Read as local software. Official npm package paperclipai (Node.js 24.11 or newer) and a Docker image on GHCR (20). Public CI that runs the tests (pr-trusted.yml selects and runs the test shards, and e2e.yml runs the end-to-end suite), with the pass state on master unreadable on 4 November 2026 because GitHub's pages answer 403 here (15). Per the 8 October check, not re-read on 4 November, 2,849 open issues, 125 labelled bug, 1,599 opened before 8 July, and 78 closed in the last 30 days against 686 opened (6). Calendar versions in semver syntax, with a Breaking Changes section and an upgrade guide in release notes, but breaking changes arrive in ordinary releases and 2026.916.0 carried five (10). No 1.0. The npm latest tag is called the stable channel and follows a beta soak of at least three days, while the roadmap says the product is still moving quickly, so half credit (8). 20 + 15 + 6 + 10 + 8 = 59.

T3 Code 43

Local software. An install script and desktop and mobile apps from the vendor (20). ci.yml and windows-tests.yml run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Stable tags v0.1.5 to v0.1.7 with many nightlies, no changelog file (8). Version 0.1.7 (0). 20 + 15 + 0 + 8 + 0 = 43.

Transparency & trust Paperclip +15

Paperclip 66

MIT (30). The privacy policy of 23 July 2026 separates self-hosted use from the hosted services and names Paperclip Labs, Inc., but keeps data as long as reasonably necessary, lists no subprocessors, and the 90-day telemetry retention appears only in source. The terms grant a broad licence over content sent to the services and allow model training on opt-in detailed telemetry (16). Release notes carry dated Breaking Changes sections and upgrade guides, with no written deprecation policy or notice period (10). The README discloses telemetry, what it excludes and four opt-outs, and the event contract is public in the repository, but it is on by default (17).

T3 Code 51

MIT (30). docs/user/telemetry.md lists what is sent and what isn't, but includes hashed third-party account identifiers and the README doesn't mention it (15 of 30). No deprecation policy (5). Disclosed with an opt-out, on by default (12 of 20). 30 + 15 + 5 + 12 = 62.

Agent ergonomics Paperclip +10

Paperclip 70

Harness reading of the framework line, scored on what an agent or pipeline driving it has to supply. The MCP server lists 44 tools with no toolsets or read-only subset found, offset by compact reads such as paperclipInboxLite and the heartbeat context (12). Budgets by company, agent and project with an automatic pause at 100 per cent, though the README says enforcement uses recorded spend and can lag work in flight (16). onboard --yes, CLI commands with --json, the REST API and routines started by cron, webhook or API (16). Atomic task checkout with a documented 409, Idempotency-Key on routine triggers, saved sessions and bounded recovery (17). One command starts a server with embedded PostgreSQL, but it needs Node.js 24.11 and each harness CLI installed and signed in on the host, and we found no client SDK beyond the TypeScript plugin SDK (9).

T3 Code 60

Harness reading. Remote control from phone or browser, portable handoffs between providers and managed policies for teams (60).

How the scores have moved

Verdicts

Paperclip

Board approvals, budgets with a hard stop and an activity log sit above whichever harnesses do the work, with ten stable versions in 90 days. The Claude Code and Codex adapters skip permission prompts and the sandbox by default, twelve security advisories have appeared since April 2026, and a 24 October cross-company read fix is in no stable release.

T3 Code

A fast-moving open-source way to run and steer several coding agents from desktop, browser or phone, using the subscriptions you already have. It's pre-1.0, and it sends usage data by default, including hashed identifiers for your OpenAI and Claude accounts, with the opt-out documented outside the README.

Before you call either

Paperclip

  1. Set PAPERCLIP_TELEMETRY_DISABLED=1 or DO_NOT_TRACK=1 before the first start. Telemetry is on by default
  2. Set dangerouslySkipPermissions and dangerouslyBypassApprovalsAndSandbox to false on agents that read untrusted input, or run them in a sandbox provider
  3. Install with Node.js 24.11 or newer, and install and sign in to each harness CLI on the host first. Paperclip assumes they are there
  4. Use --bind lan or --bind tailnet at onboarding for anything beyond one machine. The default local_trusted mode treats every request as the board admin
  5. Treat 409 on task checkout as owned by another agent and pick different work. The API docs say not to retry

T3 Code

  1. Set T3CODE_TELEMETRY_ENABLED=false before starting the server if you don't want usage events sent
  2. Install and log in to at least one provider CLI first, such as codex login or claude auth login
  3. Use a managed policy to fix settings across a team

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
