praisonai-triage-agent[bot]andMervin Praison ccc4058b17 revert: restore intentional defects in ai_code_editor_fixture
The AI code-editor smoke-test fixture is intentionally broken so live
scenarios (implement celsius_to_fahrenheit / fahrenheit_to_celsius / mode,
fix mean/median empty-list handling) exercise the AI editor's repair
capability. Pre-implementing these functions caused acceptance tests to
pass WITHOUT the editor doing any work, defeating the fixture's purpose.

Also removes the redundant conftest.py sys.path mutation; pyproject.toml
already sets pythonpath = ["src"].

For a single agent, two words cover it — and they answer different questions:
For a single agent, pick the axis you need — remote **tools** or a remote **loop**:
```python
from praisonaiagents import Agent
from praisonai import Agent, LocalAgent, LocalAgentConfig, HostedAgent
# A. Only the TOOLS move. Thinking stays on your machine.
agent = Agent(name="builder", instructions="You build things.",
tools_run_on="docker") # docker | e2b | modal | daytona | flyio
# tenki | sandlock | ssh | novita | subprocess
# A. Tools run in a remote sandbox; the agent loop stays local
agent = Agent(name="builder", backend=LocalAgent(
compute="e2b", # or modal | daytona | flyio | docker | tenki
config=LocalAgentConfig(model="gpt-4o-mini", name="RemoteTools"),
))
# B. The WHOLE agent moves — model calls, loop and tools
agent = Agent(name="teacher", instructions="You teach.", run_on="anthropic") # hosted
agent = Agent(name="builder", instructions="You build.", run_on="docker") # self-hosted
# B. The entire agent loop runs in the cloud (needs ANTHROPIC_API_KEY)
agent = Agent(name="teacher", backend=HostedAgent(provider="anthropic"))
agent.start("Write a Python script that prints the first 10 primes, then run it")
```
Ask any object where it runs, and it will tell you:
```python
>>> Agent(name="builder", instructions="x", tools_run_on="docker")
Agent(name='builder', thinks_on='this machine', tools_run_on='a Docker container')
>>> agent.where_does_it_run()
Thinking (the AI model calls) happens on this machine.
Tools run on a Docker container.
Your own tools (check_db) still run on this machine -- only shell, file and
code tools move. They read and write this machine's files.
```
Naming a place that cannot do the job is a typo, not a preference, so it says so:
```python
>>> Agent(name="x", instructions="i", run_on="e2b")
TypeError: Agent(run_on='e2b') is not valid: run_on= places the whole agent
-- model calls, loop and tools -- on a managed runtime, and 'e2b' runs
commands but cannot host an agent loop.
To run only the tools there: Agent(tools_run_on='e2b')
```
To run one block of code somewhere else, name the place on that call:
```python
agent.execute_code_sync("print(6 * 7)", run_in="sandlock") # kernel-enforced
```
See what is running and reclaim strays:

"""One vocabulary for "where does this run?", shared by Agent, AgentFlow and AgentTeam.
Two questions get asked about placement and they have different answers:

of it on someone else's machine. Only a *managed runtime* can answer this,
because running the loop remotely means something has to host the loop.
``tools_run_on=``
Where **the tools** run. Thinking stays on this machine; only the shell,
the file writes and the code execution move. Any sandbox or compute place
can answer this, because all it has to do is run a command.
Keeping the two words apart is the entire point. The old surface used one word
(``run_on=``) on ``AgentFlow``/``AgentTeam`` for the tools-only meaning, another
(``compute=``) on ``LocalAgent`` for exactly the same meaning, and a third
(``backend=``) for the whole-agent meaning -- so the same concept had two names
and one name had two concepts.
Because the two questions have disjoint answer sets, a wrong pairing is a typo
worth catching rather than a preference worth honouring. ``run_on="docker"``
cannot mean anything: Docker does not host agent loops. It gets a ``TypeError``

"""Give a single Agent's tools a sandbox, without touching its thinking.
``AgentFlow``/``AgentTeam`` already share one sandbox across a run and tear it
down when the run ends. A lone ``Agent(tools_run_on=...)`` has no "run" to hang
that lifetime on -- it is just an object someone calls ``chat()`` on, possibly
many times -- so the sandbox is created on first use and lives as long as the
agent does. That is deliberate: a file written in turn 1 is still there in turn
2, which is what anyone who asked for a working directory expects.
Attachment is idempotent and happens at the top of ``chat``/``achat``/
``_start_stream``, and in ``AgentTeam`` before the task's tool list is
snapshotted. Doing it once, rather than wrapping each call in a context
manager, sidesteps two real hazards in this codebase:
* ``_start_stream`` is a **generator**; a context manager around the call would
exit before the caller consumed a single token, tearing down the sandbox while
the model was still using it.
* ``_start_stream`` falls back to ``self.chat``, so a wrapper would **re-enter**
itself and provision a second sandbox.
Lifetime is tied to the agent by ``weakref.finalize`` rather than a process-exit
hook over a weak set. The weak set leaked: an agent and its ``SharedCompute``
reference each other, so a dropped agent was reclaimed by the cycle collector,
vanished from the set, and its sandbox was never shut down. Gateways clone an
agent **per request**, so that was one orphaned container per request.

"""Default structured summary builder for context compaction.
This is the concrete :class:`~praisonaiagents.compaction.protocols.
SummaryBuilderProtocol` implementation that renders the declared

sections (``## Active Task`` / ``## Completed Actions`` / ``## In Progress`` /
``## Pending Questions`` / ``## Relevant Files / Paths`` / ``## Remaining
Work``) — so a compacted context keeps its structure instead of degrading to a
one-line ``"Summary of N messages"`` count.
Design: **deterministic, dependency-free, offline-safe.** It categorises the
transcript into the template sections from the messages themselves (roles,
tool calls, question marks, file-path tokens) rather than making an LLM call, so
it never blocks the hot compaction path, never adds a runtime dependency, and
never raises into the loop. File paths and identifiers are preserved verbatim.
When an optional ``llm_summarize_fn`` is supplied the builder still renders the
same template shape; on any failure it falls back to the deterministic render,
honouring the issue's "fall back to the plain summary on failure" rule.

"""
Provider Quota Coordination for PraisonAI Agents.
Provides a lightweight, protocol-driven seam so provider-quota state
(credential cooldowns / benches) can be coordinated *fleet-wide* when a
shared backend is configured, while defaulting to today's in-process,
in-memory behaviour with zero new dependencies and no hot-path change.
Design:
- ``QuotaCoordinatorProtocol`` is a pure contract (stdlib + typing only).
- ``LocalQuotaCoordinator`` is the default in-memory implementation used
when no shared backend is selected — single-replica deployments behave
exactly as before.
- A concrete shared backend (e.g. Redis, reusing the gateway's existing
connection) implements the same protocol in the wrapper/bot package and
is selected via ``QuotaCoordinatorConfig``. Core keeps only the protocol
and the in-memory default.
Fail-open by contract: implementations MUST degrade to local behaviour on
backend errors rather than wedge a healthy request path, and bench entries
carry TTLs so a dead replica's benches self-expire.

MCP OAuth Metadata Discovery.

- Parse a ``WWW-Authenticate: Bearer resource_metadata="..."`` challenge from a

- Fetch protected-resource metadata (``/.well-known/oauth-protected-resource``).
- Fetch authorization-server metadata

no top-level `session_id` parameter — passing one raises

## Context Caching
Prompt caching is opt-in via `caching=CachingConfig(prompt_caching=True)` — there
is no top-level `prompt_caching` parameter on `Agent`. When enabled, `Agent`
checks `praisonaiagents.llm.model_capabilities.supports_prompt_caching(model)`
and, for providers that need explicit breakpoints (Anthropic), injects
`cache_control` markers itself. OpenAI/Gemini use automatic prefix caching, so no
markers are emitted:
For cost optimization, use `prompt_caching=True` with Anthropic models:
```python
from praisonaiagents import Agent, MemoryConfig, CachingConfig
agent = Agent(
name="Assistant",
llm="anthropic/claude-sonnet-4-5",
memory=MemoryConfig(session_id="my-session"),
caching=CachingConfig(prompt_caching=True),
session_id="my-session",
prompt_caching=True, # Enables Anthropic prompt caching
)
```
This caches the system prompt, reducing token costs for repeated conversations.
Without `prompt_caching=True`, no `cache_control` breakpoints are injected on the
Anthropic path.
