What is checkhelper?
checkhelper grew from a check wrapper into a CRAN pre-submission auditor.
Two years of near-silence ended with a 1.0.0 that adds a whole audit_* family: audit_downloads(), audit_description(), audit_dontrun() and audit_citation(), each parsing package source statically and returning a tibble of hits paired with a suggested fix. check_n_covr() runs R CMD check and coverage in a single test pass instead of two.
What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.

◆ Current state
Two years of near-silence ended with a 1.0.0 that adds a whole audit_* family: audit_downloads(), audit_description(), audit_dontrun() and audit_citation(), each parsing package source statically and returning a tibble of hits paired with a suggested fix. check_n_covr() runs R CMD check and coverage in a single test pass instead of two.
◆ Where it's heading
The design commitment is static analysis — AST walks via getParseData(), line-by-line Rd reading, no eval() and no namespace loading — so the tool can report on a package it never runs. The existing fix_globals() was reworked the same way: it merges with an existing R/globals.R instead of overwriting it, and separates data.table and rlang pronouns from real undeclared globals so they get an @importFrom line rather than a globalVariables() entry.
◆ Prediction
Each additional CRAN incoming-check rule is a candidate for another audit_* function; the open question these notes leave is whether the family ever gets a single combined entry point.
Merge
6.3INFRA · APIS
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
