buildFilterCommentsJSON serializes comments into a JSON array with generated IDs.

buildMessageXML serializes msgs into the <message><content> form expected by the MEMORY_COMPRESSION_TASK prompt template.

buildSummaryCommentsList renders comments as a compact path-anchored markdown list suitable for embedding in the PROJECT_SUMMARY_TASK prompt. Format:

Build the category/severity badge for a comment.

canonicalRemote reduces a git remote URL to a stable, credential-free identity string for hashing into repository.identity_sha256, so the same reposit

checkMetricErr intentionally ignores metric registration errors: telemetry is best-effort and must not interrupt the main flow.

classifyItemError maps a subtask error to a stable item failure class and a safe, generic reason. It never returns the raw error text (which may embed

completeSessionIDs offers the persisted session ids for the current repo (or --repo, when already typed) as shell completions, newest first, with a sh

copyMessages creates a shallow copy of a message slice.

countLines returns the number of lines in content. A file without a trailing newline still counts its final line. Empty input → 0.

countReviewable counts diffs that will survive all filters and are not pure deletions.

cursorOnDeletableModel reports whether the model-step cursor is on a row that can be deleted (not on "Enter custom model name...").

customAPIKeyForSave reports the API key to persist and whether the user edited the field (vs left the masked placeholder untouched).

estimateDiffCost projects token usage for reviewing the given diffs. It is the diff-path analogue of scan.estimateCost and is used for the pre-review

estimateCost projects token usage for reviewing the given items under the supplied scan template. planEnabled / dedupEnabled / summaryEnabled reflect

extFromPath returns the file extension with leading dot, lowercased.

extractCodeBlock extracts the content of the first fenced code block from text. Returns empty string if no code block is found.

filterByPaths keeps only entries whose path equals a user-supplied path (for exact files) or lies under it (for directories).

filterDiffs drops diffs that should not be reviewed based on user-configured include/exclude patterns and default extension/path filters.

filterScanItems drops items that should not be reviewed under the standard reviewability rules (binary, extension allowlist, user include/exclude, def

formatToolDefs renders tool definitions as human-readable text for embedding in prompts.

hostGuard returns a middleware that rejects requests whose Host header is not on the allowlist. This blocks DNS-rebinding attacks against the local vi

hostOnly returns the bare host portion of a Host header value, with any port stripped and surrounding brackets removed from IPv6 literals. Empty or ma

initConsoleProviders sets up stdout exporters for traces and metrics.

initManifest seeds the run manifest with this run's input identity and execution provenance. It is nil-safe (the builder is absent on the delegate pre

initRepoWithNonASCIIChange creates a repository whose changed file path contains both non-ASCII characters and Next.js-style route groups. It forces G

injectDiffMap builds a read-only DiffMap from parsed diffs and sets it on the FileReadDiffProvider. Must be called after loadDiffs and before any conc

injectScanContentMap fills the file_read_diff tool's DiffMap with full file content keyed by path, so if the model calls it the tool returns the whole

isBinaryFile reads up to binarySniffWindow bytes from path and reports whether they contain a NUL byte (git's "binary" heuristic).

isLoopbackHost reports whether host is a loopback name or IP literal that is always safe to accept regardless of operator configuration.

listFiles returns all source files under repoDir. In a git repo it uses `git ls-files` for full .gitignore semantics (nested + global excludes + negat

loadDiffs populates the diff-related fields.
