Manifest is an open-source gateway that gives AI agents and applications one OpenAI-compatible endpoint for API keys, subscriptions, local models, and other providers. It routes requests, records query data, tracks usage, and can fall back when a model request fails. The catalogue entry includes instructions, a hook, and a setting for operating Manifest.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.20199 | $0.20199 |
| Opus 5.5 | $0.08080 | $0.08080 |
| Sonnet 5.5 | $0.04040 | $0.04040 |
| Haiku 4.5 | $0.02020 | $0.02020 |
Grade A, and why
manifest CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What Manifest Is
Manifest is a smart model router for AI agents. It sits between an agent and its LLM providers, scores each request, and routes it to the cheapest model that can handle it. The dashboard tracks logical requests and their provider attempts, costs, and tokens across any agent that speaks OpenAI-compatible HTTP.
"Harness" is the dashboard word for an agent. The UI now labels agents Harnesses (nav item "Harnesses", routes under /harnesses, categories AI agent / App AI SDK / Coding Assistant from CATEGORY_LABELS in packages/shared/src/agent-type.ts). This is a copy-level rename only: backend code, database tables (agents, agent_messages, …), API routes (/api/v1/agents/*), and entity/service names all still say agent. Legacy /agents/* dashboard URLs redirect to /harnesses/*. When writing UI copy say "harness"; when writing code or API docs keep "agent".
Pivot note: Manifest is pivoting toward "the self-healing layer for APIs" (see the README banner). The dashboard shows a sidebar PivotAnnouncement card with a waiting-list modal in every deployment mode (per-session dismiss); waiting-list claims land on POST /api/v1/waitlist/pivot/claim and record their origin (cloud vs self-hosted). The open-source gateway remains available and maintained.
Supported agents: see AGENT_PLATFORMS in packages/shared/src/agent-type.ts for the current list (OpenClaw, Hermes, Claude Code, OpenCode, generic OpenAI/Anthropic SDK slots, and others — don't duplicate the list here, it grows independently of this doc). OpenClaw remains the deepest integration, but no new code or copy should frame Manifest as OpenClaw-only. When adding examples, prefer "AI agent" as the noun and pick OpenClaw as the worked example rather than the sole target. Manifest is consumed as a generic OpenAI-compatible HTTP endpoint — there are no first-party OpenClaw plugins in this repo anymore.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

manifest CLAUDE.md is an instructions file published in the GitHub repository mnfst/manifest (7,611 stars, last pushed 8d ago), licensed MIT. It adds 20,199 tokens to every session, about $0.0808 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
