edit: a config kept as a symlink stays one when magpie saves or clears it (#323, jigaowan) — WriteAtomic wrote a temp file beside the path and renamed it over it, so a linked library.json, instructions.md, CLAUDE.md, settings.json or config.toml became a file of its own and the dotfiles target kept its old text; clearing instructions.md removed the link. Now a write goes to the file at the end of the links (the one it names when nothing is there yet, an error for a loop of links), keeping its mode, and clearing a linked file empties its target and keeps the link (Pi's migrated mcp.json stays as {}); a plain file is removed as before. Sign-ins and the Kiro/StepFun files magpie writes privately follow links the same way, and a failed edit rolled back deletes only what it made behind a link to nothing. TestWriteAtomicFollowsSymlink, TestRemoveKeepsSymlink, TestAtomicallyKeepsSymlink, TestLinkedFilesStayLinked and TestPrivateWritesKeepSymlink fail without the change. go vet, go build -tags nogui (darwin, GOOS=linux), GOOS=windows go build, go test -tags nogui ./... pass.
goose: a key magpie adds to config.yaml goes after the whole last entry, never between extensions: and its children (found reviewing #431) — SetYAMLTop put a new top-level key right after the last top-level key line, so on a config.yaml ending in an extensions: block, magpie goose effort off wrote GOOSE_THINKING_EFFORT between extensions: and its indented children and Goose's config no longer parsed. A top-level entry is now its key line plus its indented lines, a sequence written at column 0 under it, and blank or column-0 comment lines between them (and the trailing blank lines of a |+ block scalar); a new key goes after the last such entry, before any trailing blank lines and comments. Setting or removing a key whose value ran over several lines now replaces or removes those lines too. Every other line stays byte for byte. TestYAMLTopAfterBlockEntry (block mapping, sequences, block scalars, no trailing newline, empty file, a block value replaced) fails without the change and checks each result parses with yaml.v3 and keeps the other keys' values. go vet, go build -tags nogui (darwin, GOOS=linux), GOOS=windows go build, go test -tags nogui ./... pass; the reviewer's goose431.sh repro in a sandbox HOME now yields a config.yaml that parses.
toml: Codex's config.toml with a multi-line array (notify = [ … ]) is edited right, and an edit that fails leaves every file as it was (#253 kerwinliu00001: "edited TOML is invalid: line 2, column 1: incomplete number", config.toml left with model_provider gone and [model_providers.magpie] added but no model) — the top-level key edits (GetTOMLTop, SetTOMLTop, DelTOMLTop) went line by line with regexes: a new key went after the last line that looked like
key = …, which for notify = [ was inside the array; key = value lines inside a multi-line string were read as keys and a line starting with [ as a table; replacing or deleting a multi-line value touched only its first line. They now locate the top-level keys with the TOML parser, as the table edits already did, each with its value's whole range however many lines it takes (parseTOMLFile, the unnamed root table beside the tables); SetTOMLTop finds all its keys in the file as read and writes once. A file the parser refuses is still read line by line, so a broken config keeps showing its model, and writes to it are refused untouched. And a pick is several writes (Codex: drop model_provider, add magpie's provider table, set openai_base_url and model), each checked, so one failing left the earlier ones on disk: edit.Atomically(fn, paths…) puts each file back to its bytes and mode, or removes one it created, when fn fails, and every field set and Sync of Codex (config.toml and magpie-models.json, so Codex in WSL too), Kimi and Grok goes through it, as do Codex's MCP server writes (putCodex, delCodex). Tested in temp dirs and a temp HOME: the reporter's file read, set and deleted directly and through Codex's model field (signed in, with model_provider and model above the array, with magpie as the provider), the array's text kept and the TOML valid, and back to a Codex model; nested arrays, trailing commas, comments in arrays, [x] and a = b in strings, an inline table in an array; """ and ''' strings holding model = … and [table] lines not read as keys, new keys after their closing quotes, one deleted whole; a forced failure of Codex's last write leaving config.toml byte-identical; TestAtomically. They fail on main (the Codex ones with the reporter's error). go vet ./internal/..., go build -tags nogui (and GOOS=linux, GOOS=windows) and go test -tags nogui ./... pass. Not tried against a real ~/.codex, in WSL or in the GUI; multi-line inline tables (TOML 1.1) are refused by the parser and so left untouched with an error.

agent: omp (oh-my-pi) — its model picked in magpie like any agent's; a model through magpie adds magpie as a keyless provider in ~/.omp/agent/models.yml with the catalog as its models, and sets config.yml's modelRoles.default to magpie/<provider>/<model>; its other roles and the rest of both files stay as they are, comments too, and default takes magpie's entry out unless another role still uses it (#34)
