Individual AI access changed time use, not the mix of tasks
A six-month randomized field experiment covered 66 firms and 7,137 knowledge
workers. It added a generative AI tool to the email, meeting and writing applications
they already used. The 80% of treated workers who used it spent two fewer hours a week on
email in the experiment's second half. They also did less work out of hours. Apart from
those individual time savings, the authors "do not detect shifts in the quantity or
composition of workers' tasks resulting from individual-level AI provision".
What we use it for: telling time saved by one person apart from a
change in how work is organized. The World Economic
Forum's September 2026 piece
frames the same result as the "single-player" phase of workplace AI. Knowledge shared
between agents is the second kind of change, the one doublegate offers, and its effects
need their own measurement.
Study scope: the tool tested was an office assistant.
The experiment did not evaluate shared agent memory. It did not establish why task
patterns stayed unchanged.

Meta built a reviewed institutional knowledge system
Meta's "organizational second brain" uses adversarial review by an agent that shares no
context with the author. Its validation passes or fails rather than scoring. A human
expert signs off, and the audit trail is complete. Meta's engineers write that they
"haven't seen this level of validation rigor applied to a structured knowledge base
without model retraining". They describe the output as "permanent, compounding institutional
memory".
What we use it for: a team independent of us built a way to turn
expert corrections into reviewed knowledge updates. The article evaluates Meta's system,
not doublegate, and it is not a market survey.

Two of fourteen memory providers can hold changes for review
Of the fourteen memory providers we surveyed in September 2026, two offer a review
step before what an agent writes is final. Since version 3.14.0, Mnemosyne can hold
everything written until it is approved. Byterover holds back two kinds of change from
the rest of the team: a deletion, and a change its own curation agent rates high-impact.
The author's own queries already see the change. In both, the agent that wrote a change
can approve it, and neither records the decision as a signed event.
What we use it for: holding back what an agent writes is no
longer rare. The difference left is who may approve, and whether the decision is signed.
We read both
providers' own documentation on 2026-10-06. The survey of the fourteen is our own.

More than a third of public agent skills had a security flaw
A skill is a set of instructions, sometimes with scripts, that changes what an agent
does. Of 3,984 public agent skills scanned, 36.8% had at least one security flaw
and 13.4% a critical one. The scan confirmed 76 malicious payloads, 8 of them still live
when the study was published. Of the malicious ones, 91% paired prompt injection with
conventional malware. The barrier to publishing a skill was a single file and a git
repository.
What we use it for: why a skill is held, scanned and reviewed
like anything else an agent writes, instead of going straight into use.

Packed skill malware got past every scanner tested
The authors took 1,613 malicious skills found in the wild and packed each one.
Packing hides the payload when the skill is installed and restores it when the skill
runs. They tested eight scanners: six that inspect a skill without running it, and
two that ask a language model to judge it. The packed skills got past every one more than
90% of the time, with the two model judges tried on a random 100 of the skills.
Disguising the payload's code, instead of packing it, got past most of the six
non-running scanners more than 80% of the time. The authors' own answer was to run each
skill in a sandbox and watch what it does. It detected 97% of attacks at a 2%
false-positive rate.
What we use it for: the gate's grading model reads a skill as it
would be installed. That is the same kind of check as the two model judges the packed skills got
past. So a grade of a skill proves no more than the scan does. Both hold a skill for
review and never prove it safe, and review is not permission to run it.

Public registries exclude curation by design, and say so
The official registry of the Model Context Protocol, the standard agent-tool
protocol, publishes its design principles. In them it commits itself to "no built-in ranking, curation, or quality judgments"
and to "avoid features that require constant human intervention or
moderation". Its ecosystem document expects that role to be filled by
"subregistries [that] add value […] by providing curation".
Hugging Face, the most mature artifact registry in AI, scans uploads and states:
this is not 100% foolproof. It is your responsibility as a user to check if something
is safe or not. We are not actively auditing python packages for safety.
What we use it for: by their own design, the registries leave
review to whoever installs, for stated reasons: operational cost, vendor neutrality and
liability. Whoever reviews instead carries those costs.

A correction we made to our own case
Much published material states that BCBS 239 requires data lineage. We searched
the full 2013 text: zero occurrences of "lineage", "provenance", "traceability" or
"audit trail". The document requires reconciliation with source systems, and striving
toward "a single authoritative source for risk data per each type of risk". That is a
different requirement from a lineage mandate, and a weaker one.
The lineage requirement is real. It lives in the ECB's 2024 implementation
guide. The guide states lineage must let a bank "track back the source of the issue in a
timely manner" and "allow traceability for (external) validation". That is the document we
cite.
Why this is here: a bank's risk and compliance function, its
second line of defence, is paid to catch borrowed authority. Quoting the better-known
document as a lineage mandate is that kind of borrowed authority. We would rather lose the stronger-sounding citation
than be caught using it.
