Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security87

No malware found by supply-chain analysis.Pass
Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
No install/post-install scripts declared.Pass
Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial

Provenance & Transparency45

Source repository is publicly reachable at the declared URL. View diagnostics → Pass
Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
Clear OSI-approved license (MIT).Pass
Actively maintained (last published 120 days ago).Pass
Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail

Schema Quality & AI Usability66

AI-judged instruction clarity (good).Pass
Tool/resource definitions use about 531 tokens (~106/item across 5 items; 5 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management0

Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

The dependency tree was only partially resolved, so these counts may be incomplete.

MCP tools — 5 exposed · ~459 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

flush ~63

Clear all short-term KV slots for a session. Call at agent task completion to free memory. Mirrors the teardown of a memory_silo_t allocation (PMLL.c::free_pml).

Input Output Examples

Name	Type	Req	Description
session_id	string	yes	The session identifier (from `init`).

No output schema declared.

No examples provided.

init ~98

Initialise the PMLL memory silo for an agent session. Call this once at the start of every agent task, as the 3rd initializer alongside Playwright. Sets up the KV silo and prepares the Q-promise chain for the session.

Input Output Examples

Name	Type	Req	Description
session_id	string	yes	Unique identifier for this agent task (e.g. a UUID).
silo_size	integer	—	Maximum number of KV slots (mirrors memory_silo_t.size).

No output schema declared.

No examples provided.

peek ~84

Non-destructive context check — the core deduplication primitive. Call this before any Playwright or other MCP tool invocation to check whether the required context already exists in the PMLL silo or is in-flight as a Q-promise.

Input Output Examples

Name	Type	Req	Description
key	string	yes	The context key to look up.
session_id	string	yes	The session identifier (from `init`).

No output schema declared.

No examples provided.

resolve ~109

Check or resolve a Q-promise continuation. Mirrors the `QThenCallback` mechanism in Q_promise_lib/Q_promises.h — the callback is invoked when a QMemNode's payload becomes available. If the promise is already resolved, returns its payload immediately. If still pending, returns `{status: "pending", payload: null}`.

Input Output Examples

Name	Type	Req	Description
promise_id	string	yes	The promise identifier previously registered.
session_id	string	yes	The session identifier (for context; not used to namespace promises).

No output schema declared.

No examples provided.

set ~105

Store a KV pair in the session's PMLL memory silo. Call after a successful (non-cached) MCP tool invocation to populate the silo so future `peek` calls return a cache hit. Mirrors PMLL.c::update_silo() writing a var/value pair into the silo.

Input Output Examples

Name	Type	Req	Description
key	string	yes	The context key.
session_id	string	yes	The session identifier (from `init`).
value	string	yes	The string value to cache.

No output schema declared.

No examples provided.
