Kiro CLI scores 59.8 (C) on agent readiness against Conductor's 41.3 (E), and leads in every scored category. Both do agent harnesses.

- Conductor: E 41.3, rank #1285 of 1486 · https://www.anchorterminal.com/tools/conductor.min.md
- Kiro CLI: C 59.8, rank #675 of 1486 · https://www.anchorterminal.com/tools/kiro-cli.min.md
- Conductor, good for Existing Conductor users planning their move before Cloud closes on 20 November 2026 and the local app winds down in early 2027. Also No incidents deducted, where Kiro CLI loses 5 points for them.
- Kiro CLI, good for Teams on AWS that want one agent configuration across terminal, IDE and web, with central permission policy, prompt logging to their own S3 bucket and IAM Identity Centre sign-in.

Why the edge:
- Payments & pricing, Kiro CLI +40: Conductor 0 (No new sign-ups since 4 November, free users can't upgrade, and no price is shown. No protocol, no published price, no open free tier, no onboarding (0).); Kiro CLI 40 (Harness reading of the published rubric, scored on the Kiro subscription the CLI needs. No payment protocol (0). Plan prices, the $0.04 credit price and per-model credit multipliers are public without a login (20). Kiro Free has 50 credits a month, and the pricing page asks for a card only on upgrade (20). A person signs in through a browser or device flow, and the API key for headless runs is created by hand at app.kiro.dev on a paid plan (0).)
- Reliability, Kiro CLI +32: Conductor 25 (Read as local software that is winding down. Installed from Conductor's own download, which stopped taking new users on 4 November 2026 (10). Closed source, so no public CI or issue tracker (0, 0). A dated changelog, newest 0.93.0 on 4 November (15). Version 0.93 (0). 10 + 0 + 0 + 15 + 0 = 25.); Kiro CLI 57 (Local-package reading, the same as the other closed-source harnesses. An install script that verifies SHA-256 checksums, a .deb, an AppImage and a PowerShell script, with macOS, Windows 11 and Linux (glibc 2.34 or newer, or musl) stated, per the 8 October check (20). No public CI or test suite, since the source isn't published and the GitHub repository is an issue tracker whose newest commit is 27 August (0). Per the 8 October check, not re-read on 3 November, 1,401 open issues in the shared Kiro tracker, 428 labelled cli, with 96 cli issues opened and 69 closed in the 30 days to 8 October, area labels, a triage label and stale-issue automation (12). A dated changelog for every release, and 3.0.0 lists its breaking changes under their own heading with a migration route, though 2.24.0 stopped loading project `.env` files in a minor version (10). 3.0.0 on 3 November 2026 makes V3 the default engine (15). 20+0+12+10+15 = 57.)
- Security & auth, Kiro CLI +24: Conductor 45 (Closed app. Telemetry and data handling weren't read beyond the transition notice (10 of 30). A security and permissions page (10 of 20). No prompt-injection guidance found (5). No audit log found (5). SOC 2 Type II report at trust.conductor.build (15 of 20). 10 + 10 + 5 + 5 + 15 = 45.); Kiro CLI 69 (Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. Telemetry and content collection are on by default for Free and individual accounts, each with a documented opt-out, and enterprise users are opted out. API keys are long-lived and revocable with no scopes, and administrators must switch key generation on (14). Deny over ask over allow across six scopes, hard-coded denies on Kiro's own settings paths, workspace trust and a managed policy that fails closed. V3 is the default since 3.0.0 (3 November 2026), interactive V3 sessions ask before loading a folder's hooks, agents and MCP servers since 2.33.0, and `/sandbox` puts agent shell commands and local stdio MCP servers in an operating-system sandbox. The sandbox is off unless chosen and doesn't cover the agent, built-in file tools or remote MCP servers, and AWS says managed policies are client-enforced and can be circumvented (17). An untrusted workspace doesn't load its agents, steering, MCP configuration or skills, compound shell commands are split before matching, and the MCP page warns that servers run outside any sandbox (11). Enterprise prompt logging to the customer's S3 bucket covers the CLI, with daily activity reports and OpenTelemetry export, and individuals have local logs only (11). AWS vulnerability reporting through a HackerOne disclosure programme with no paid bounty, CVEs published in security bulletins with credit to reporters, ISO/IEC 27001:2022 scope and HIPAA eligibility. The aws.amazon.com security.txt is valid (Expires 2027-10-16) and kiro.dev/.well-known/security.txt answers 404, so 2 are held back for that and 2 for no bounty (16). 14+17+11+11+16 = 69.)
- Schema & documentation, Kiro CLI +19: Conductor 60 (Harness reading. Docs for workspaces, review and merge, a Conductor API reference page linked from the docs (not read), and security and permissions pages (60).); Kiro CLI 79 (Framework reading. A command reference, a settings reference, an exit-code page and a documented rule format for permissions, plus the Agent Client Protocol methods the CLI implements. No published schema for the stream-json events was found (14). kiro.dev/llms.txt indexes every docs page and each has a Markdown twin, though robots.txt disallows both for crawlers (10). The permissions page states the defaults, what each preset allows and when to pick it, and that headless runs treat ask as deny (16). Rules are validated, an unknown preset rejects the session request, and a malformed managed policy fails closed (12). CI examples, exit codes 0, 1, 3 and 4 and hook exit codes are documented, but code 1 covers every other failure (12). Versioned releases with a dated changelog and a 2.x reference kept beside V3 (15).)
- Transparency & trust, Kiro CLI +18: Conductor 53 (Closed service with terms and privacy pages (15). The transition notice says when Cloud data deletion begins (20 November) and that all user data is deleted when the app shuts down in early 2027 (20 of 30). Dated shutdown notice (15 of 20). SOC 2 report on a trust portal, subprocessors not read (10 of 20). 15 + 20 + 15 + 10 = 60.); Kiro CLI 71 (Proprietary, with clear terms. The licence page puts the CLI under the AWS Customer Agreement and the AWS Intellectual Property Licence, where the Amazon Q Developer CLI it replaced was Apache 2.0, per the 8 October check (15). The data protection page (updated 23 October 2026) says what is stored for Free, individual and enterprise users, names US East (N. Virginia) for storage, and gives 60 days for Free Tier abuse detection and 30 days for some models. It agrees with sections 50.3 and 50.14 of the AWS Service Terms, read on 8 October. No general retention period for stored content was found (22). The models page has a model lifecycle section with Experimental, Active and EOL stages and dates, and Claude Sonnet 4 ended on 14 October 2026. 3.0.0 made V3 the default as 2.30.0 announced and retired the Classic interface 34 days after the 2.26.0 deprecation notice, but the desktop app and inline autocomplete were retired in the same release with no earlier notice found, and no minimum notice period is stated (14). Telemetry types are listed and `kiro-cli settings telemetry.enabled` turns them off, with collection on by default. The data protection page's CLI steps still point to the desktop app's Preferences, which 3.0.0 retired (15). 15+22+14+15 = 66.)
- Maintenance & community, Kiro CLI +15: Conductor 58 (0.93.0 on 4 November 2026 (30). Several dated releases in 90 days, per the changelog index (20). Discord, a subreddit and email for support (8). Closed app, no package or CI to read (0). 30 + 20 + 8 + 0 + 0 = 58. The local app gets new models and critical fixes only until early 2027.); Kiro CLI 73 (3.0.0 on 3 November 2026, after 2.37.1 on 31 October (30). 25 dated releases from 2.17.0 on 11 August to 3.0.0 on 3 November, plus five patches, read from the first three changelog pages back to 9 July (20). A public issue tracker with area labels and triage automation, 69 cli issues closed against 96 opened in the 30 days to 8 October, and a Discord server, per the 8 October check, not re-read on 3 November. We didn't establish how many replies come from staff (14). No SDK and no registry entry. The ACP server is kept current, with ACP sign-in added in 2.37.0 and a migration guide for clients moving to V3 (6). Closed source, so no CI or dependency health to read. The installer verifies checksums (3). 30+20+14+6+3 = 73.)
