miniflux

miniflux

An AgentEnv bundle with its recorded runs, published with agentenv-hf.

Tables

• miniflux_tasks: one row per task of the bundle, with its prompt, envs, verifiers and steps.
• miniflux_episodes: one row per recorded run, with its status, model, reward and scores, the prompt and response, and the agent's transcript as chat messages when its trajectory format is one agentenv-hf reads.

raw/miniflux.jsonl holds each run's record and native trajectory, and bundles/miniflux/ the bundle itself.

Miniflux on AgentEnv, from a REA capture

What this is. A replay environment of Miniflux 2.3.3 (Apache-2.0), built from one recorded browser session against a self-hosted instance seeded with synthetic data. REA projected the capture into an environment manifest (22 tools), and rea environment-export wrote the bundle you can run from this dataset. Every tool call replays a retained record from the capture, cites the record and the Evidence it came from, and nothing executes Miniflux. Tasks are graded deterministically, with no judge.

What's in it

• 22 tools (18 GET, 2 POST, 2 PUT) over 86 recorded exchanges on http://127.0.0.1:3217; 4 recorded groups excluded (4 as non-JSON replies such as bodiless 204 writes).
• Path parameters: 13 numeric. REA's four format rules (numeric, uuid, hex, iso-date) applied unconditionally; the three opt-in rules (after-uid-literal, opaque-token, sibling-variance) were requested and are labelled per parameter. With the four format rules alone the manifest has 22 tools.
• Unknowns the manifest states explicitly: authorization model, response semantics beyond recorded exchanges, state transitions between tools.
• 7 retrieval tasks (evals/miniflux-retrieval.toml): each asks one factual question about a seeded object, with a distinct answer that the app does not ship by default, answerable through a recorded exchange; reward 1 if the response contains the recorded value, else 0. Plus smoke, which deploys the environment and checks replay through the MCP endpoint.
• 14 recorded episodes by openai/gpt-oss-120b:groq, zai-org/GLM-5.3-Flash:zai-org through the Hugging Face router, with their chat transcripts.
• Provenance: capture ev_d65576c62c9473341453db9efd48b5124980707e66c363e2c210dd404a877235 (scoped HAR sha256 da65467c3008cfc9b99d9b69cadc9c63bf8b1d66d377e0ea4b65504982c42072, 279,002 bytes), manifest view ev_87cdbc359ae8ac5356656a9666026abc94623345fffe2f620f3a1c8eee2ff841, confidence inferred, authority historical-reference. The REA build is a prerelease of the environment commands proposed upstream in morluto/rea#4954, #4955, #4975 and #4999; the bundle installs it from the tarball it ships, so the environment runs without waiting for an npm release.

What replay means, and does not

A tool call returns the recorded response whose path and query values best match the arguments, with replay.exact_match telling you whether it matched exactly or fell back to the closest record. Reads of seeded objects behave like the application. Writes return the recorded answer of the one write the session made, and the environment has no state: a created object does not appear in a later list. This is what makes retrieval tasks hard-gradable and write tasks weak; the manifest's unknowns say so.

Run it yourself

uv tool install agentenv-framework --with 'agentenv-hf @ git+https://github.com/earakely-scale/agentenv-hf-plugin@v0.3.0'
agent-env hf run earakely-scale/MinifluxEnv-REA --bundle miniflux --task smoke          # Docker, no model
agent-env hf run earakely-scale/MinifluxEnv-REA --bundle miniflux --eval miniflux-retrieval --model openai/gpt-oss-120b:groq

The retrieval eval needs a model endpoint: set [model] base_url and api_key in .agentenv/config.toml (the Hugging Face router works with any hf_ token). The bundle's agents/replay-qa is a small OpenAI-compatible tool-calling agent; any A2A agent can replace it.

How it was made

1. Miniflux ran in Docker on a throwaway VM, bound to loopback, seeded through its own API with synthetic records (admin rea-admin and a second reader mina-okafor; 3 categories (Coastal Operations, Quarry and Stone, Kitchens and Supplies; plus the default All); 4 feeds served by a local feed host (Lighthouse Rota Bulletin and Blue Heron Kitchen Specials as RSS 2.0, Granite Ledger Quarry Notes and Saltmarsh Depot Tide Log as Atom 1.0); 12 entries with invented authors (Ada Finch, Rui Castellanos, Mina Okafor, Tomas Vey, Marisol Okonkwo-Reyes); 2 entries read, 2 starred); people and projects are invented.
2. Playwright drove a login, the main pages and a scripted read, write, read sequence through the app's JSON API; the HAR was scoped to the API, the login exchange dropped, secret-looking body fields scrubbed, headers and cookies removed.
3. rea inspect-web-network-capture retained the exchanges as Evidence; rea inspect-analysis-view projected the environment-manifest view; rea environment-export wrote this bundle; gen_tasks.py derived the retrieval tasks from the manifest and the recorded bodies; agent-env run recorded the episodes; agent-env hf publish wrote this dataset. Scripts: https://github.com/earakely-scale/rea-environments.

Compared with PortSimEnv on AgentEnv

	PortSimEnv-AgentEnv	Miniflux (this dataset)
Environment	A simulation: a container quay, ships, cranes, weather, with A2A ship agents	A replay of a real application's API, captured from one session
Observation	Tool results computed by the simulator as the week unfolds	Recorded responses, cited to Evidence
Action space	Planning tools (check_plan, confirm_berths, advance, message_agent)	22 tools mirroring the application's endpoints
State	Full: a virtual clock, triggers, frozen windows, agents that answer	None: every call is independent; writes replay one recorded answer
Reward	Deterministic, against a CP-SAT optimum or a re-planner anchor; continuous 0 to 1	Deterministic, recorded-value match; 0 or 1 per task
What it measures	Planning under uncertainty and negotiation	Tool discovery, parameter inference and faithful retrieval in a real API
Data provenance	Real 2024 port calls and weather; simulated workloads	Synthetic seed data on a self-hosted Miniflux; nothing real
How it was built	Hand-written plugin, months of work	Generated from a capture in one scripted pass
Where it is strong	Long-horizon decisions with hard rewards	Breadth: any app you can capture becomes an environment

The two are complementary: PortSimEnv shows what a hand-built simulation can grade; this dataset shows how far a capture alone gets you, and the manifest's unknowns list exactly what a stateful version would still have to specify.
