The practical work is a multi-signal census for repositories, a verifier budget controller for agent runs, and exploit-backed review gates for code and tool use. ## Multi-signal repository census for coding-agent activity Open-source maintainers, security researchers, and supply-chain teams should stop treating bot accounts or pull requests as the main record of coding-agent use. A useful census scans several signals together: commit-message signatures, author-name patterns, centralized bot identities, and agent configuration files. The detector should defork projects, keep bot and human aliases separate, and hand-label a sample of each signal type before adoption numbers are used in risk or quality studies. The reason to build this into repository analytics is concrete. In the World of Code V2510 snapshot, multi-method detection found 850,157 Claude Code commits, while bot-account lookup found 28,154. In V2604, commit-attributed agents produced 1,772,677 commits, with Claude Code at 886,122. A pull-request census also missed 79% of commit-detected Claude Code adopters, while commit-only detection missed nearly all Codex adopters. A cheap internal check is to run the four-signal scan across one organization’s repos and compare it with the current audit method used for AI-assisted changes. ### Sources - [Detecting AI Coding Agents in Open Source: A Validated Multi-Method Census of 180 Million Repositories](../Inbox/2026-06-23--detecting-ai-coding-agents-in-open-source-a-validated-multi-method-census-of-180-million-repositories.md): Summarizes the multi-method census, validation method, and quantitative gaps between bot lookup, commit detection, configuration files, and pull-request traces. - [Detecting AI Coding Agents in Open Source: A Validated Multi-Method Census of 180 Million Repositories](../Inbox/2026-06-23--detecting-ai-coding-agents-in-open-source-a-validated-multi-method-census-of-180-million-repositories.md): States the abstract claim that no single detection method captures more than a fraction of total AI activity and gives the Claude Code bot-account recall gap. - [Detecting AI Coding Agents in Open Source: A Validated Multi-Method Census of 180 Million Repositories](../Inbox/2026-06-23--detecting-ai-coding-agents-in-open-source-a-validated-multi-method-census-of-180-million-repositories.md): Gives V2604 commit volumes, configuration-file findings, and the near-disjoint coverage of PR and commit channels. ## Verifier budget controller for coding-agent runs in CI Teams running coding agents against slow tests or repository-level verifiers can add a small controller before each expensive check. The controller keeps a belief that the current candidate will pass, updates it with cheap evidence such as syntax checks, public tests, or an LLM judge, and decides whether to regenerate, run another critic, call the full verifier, or stop. This is most useful for queues where a full CI run or SWE-Bench-style oracle is expensive enough to crowd out other work. The Bayesian control paper gives a direct implementation path: estimate the prior pass rate for each task class, calibrate critics with pass and fail likelihoods, attach explicit costs to generation, critics, and verification, then choose the action with the best expected utility. Its evaluation spans six generators and nine coding benchmarks, and the reported advantage appears mainly when verification is costly and critics are useful but imperfect. A team can test the idea with a replay of recent agent attempts, using recorded syntax results, unit tests, CI outcomes, and wall-clock costs to compare the controller with its current fixed loop. ### Sources - [Bayesian control for coding agents](../Inbox/2026-06-23--bayesian-control-for-coding-agents.md): Describes the Bayesian belief state, critic updates, action choices, cost model, and evaluation scope across generators and benchmarks. - [Bayesian control for coding agents](../Inbox/2026-06-23--bayesian-control-for-coding-agents.md): States the core claim that Bayesian control is most valuable when verification is costly and critics are informative but imperfect. - [Bayesian control for coding agents](../Inbox/2026-06-23--bayesian-control-for-coding-agents.md): Explains the sequential decision model over candidate correctness, critic calls, regeneration, and costly verification. ## Exploit-backed review gates for agent-written security fixes Security review for agent-written code should require executable proof that the defense works at the right boundary. A practical gate for high-risk changes can map the change to an OWASP or CERT secure-coding principle, run normal functionality tests, run an exploit or abuse test, and record whether the generated code implements the intended defense mechanism. This gives reviewers a useful failure label: the model lacked the principle, broke functionality, blocked the exploit by another route, or knew the principle but placed the defense in the wrong code path. Kauge supports this workflow by separating secure-coding knowledge, code actuation, and the gap between them. Its reported finding is that current systems often recognize the relevant secure-coding principle yet fail to translate it into secure and functional code. For agent tool use, AutoSpec adds a maintenance loop for readable safety rules: start with expert rules, label execution traces as safe or unsafe, collect false positives and false negatives, and keep rule edits only when they improve trace-level scores. On 291 traces across code-execution and embodied-agent domains, AutoSpec reports F1 scores of 0.98 and 0.93 and up to 94% false-positive reduction. A small trial can start with recent agent PRs that touched authentication, input handling, file operations, or network calls. ### Sources - [SoK: AI Secure Code Generation: Progress, Pitfalls, and Paths Forward](../Inbox/2026-06-23--sok-ai-secure-code-generation-progress-pitfalls-and-paths-forward.md): Describes Kauge’s separation of knowledge, actuation, and gap checks using OWASP and CERT principles plus exploit-oriented testing. - [SoK: AI Secure Code Generation: Progress, Pitfalls, and Paths Forward](../Inbox/2026-06-23--sok-ai-secure-code-generation-progress-pitfalls-and-paths-forward.md): States the knowledge-actuation gap: models can recognize relevant security principles but still fail to produce secure and functional code. - [AutoSpec: Safety Rule Evolution for LLM Agents via Inductive Logic Programming](../Inbox/2026-06-23--autospec-safety-rule-evolution-for-llm-agents-via-inductive-logic-programming.md): Summarizes AutoSpec’s trace-labeled rule revision loop and reports F1 scores, false-positive reduction, and convergence details.
