Addresses audit findings from a tri-partite review (codex + 2 Claude agents).
Multiple distinct fixes here because they touched overlapping files; happy
to split via interactive rebase if a reviewer prefers.
## Correctness bugs (HIGH)
* `--config` is now actually honored. cmd/root.initConfig fed Viper but
every command that mattered loaded config via `internal/config.Load()`
which always read the default path. Added `config.SetExplicitConfigPath`
consulted by `GetConfigPath`; `--config other.yaml auth login` now writes
to other.yaml.
- internal/config/config.go, cmd/root.go
* `--json` now works on `fj run …`, `fj workflow …`, and `fj wiki view`.
cmd/aliases.go registered `--json` as a Bool but the handlers call
`wantJSON()` which does `GetString("json")` and silently ignores the
type-error return. cmd/wiki.go did the inverse (`GetBool("json")` against
a string-registered flag). Both now use `addJSONFlags`/`wantJSON`/
`outputJSON` consistently.
- cmd/aliases.go, cmd/wiki.go
* `fj api` no longer lets endpoints escape the /api/v1 base via
path-traversal. `fj api '/../admin/users'` previously normalized to
`/admin/users` because `http.NewRequest` resolves `..` segments —
silently sending authenticated traffic to non-API routes. Endpoint is
now parsed, `..` segments are rejected, and JoinPath is used.
- cmd/api.go
## Design rework (BREAKING — gets rid of the `--json=fields` quirk)
* `--json` flag rebuilt from a string-with-NoOptDefVal=" " sentinel into a
plain Bool. `--json-fields` keeps comma-separated projection. The two
are mutually exclusive (`MarkFlagsMutuallyExclusive`). `--jq` composes
with either or neither. The previous design produced a `--json string[=" "]`
in --help and required `--json=fields` (with literal "=") because
`--json fields` was parsed as the bare flag plus a positional. Gone.
- cmd/json.go: addJSONFlags / wantJSON / outputJSON
- cmd/api.go: example block reflects the new shape
Migration: `--json=fields` → `--json-fields fields`. Bare `--json` still
means "everything as JSON".
* `fj api` now uses `internal/api.SharedHTTPClient` (30 s timeout, pooled)
instead of constructing a zero-value `&http.Client{}` with no timeout.
A hung Forgejo no longer pins the CLI indefinitely. Response body is
also bounded by `io.LimitReader` at 64 MB to prevent OOM-on-self.
- internal/api/client.go (export SharedHTTPClient), cmd/api.go
* `--hostname` declared as a persistent flag on rootCmd is now the only
declaration. cmd/auth.go re-declared `--hostname` on three subcommands,
shadowing the persistent flag — meaning `fj --hostname=X auth login`
and `fj auth login --hostname=X` went through different code paths
(viper read vs. local flag read). Local declarations removed.
- cmd/auth.go
## Hardening (MEDIUM/LOW)
* `--token` on `auth login` now emits a stderr warning when used, since
it puts the PAT on argv (visible in `ps auxe`/shell history). Flag not
removed — too disruptive — but discoverable now.
- cmd/auth.go
* Error handling no longer regex-matches "401"/"403" against rendered
error strings (would have triggered "auth login" hint for an error
that just mentioned issue #403). Now relies on typed `*api.APIError`.
Hints moved to a separate `Hint` field on `CLIError`, so JSON-error
consumers get clean structure and the human renderer still appends
"\nHint: …".
- cmd/errors.go
* `migrateConfigDir` now opens dst with `O_TRUNC` instead of just
`O_CREATE|O_WRONLY`. Previously a partially-pre-existing dst file
would have legacy contents overwrite a prefix and leave stale tail
bytes — silent YAML/token corruption.
- cmd/root.go (extracted into copyOneConfigFile with proper close handling)
* Config dir created with mode 0700 instead of 0755. `initConfig` warns
on stderr if the resolved config file is world/group readable
(`mode & 0o077 != 0`); doesn't fail-close.
- cmd/root.go
* Network errors (`no such host`, `connection refused`, `i/o timeout`)
now return a structured `CLIError` with code `ErrNetworkError` and a
hint, instead of a fmt.Errorf chain.
- cmd/errors.go
Verified: `go build ./...` and `go test ./...` clean. Live integration
tested against forgejo.zerova.net.
Out of scope, deferred to follow-up commits:
- Pagination unification across `repo list`/`pr list`/`issue list` (only
`release list` walks pages today; others silently truncate).
- `fj api --paginate` to follow pages like `gh api --paginate`.
- De-duplicating cmd/aliases.go ↔ cmd/actions.go subtrees.
`fj api` was the only command that returned raw API JSON without exposing
the same projection/filtering knobs that `fj repo list`, `fj pr list`,
etc. already provide. Callers had to pipe to `python -m json.tool` or
`jq` to extract fields, which is inconsistent and discoverable only
after hitting the gap.
Wire the existing addJSONFlags / wantJSON / outputJSON helpers from
cmd/json.go so the API command participates in the same JSON output
pipeline. No behavioral change when none of the new flags are set —
default still pretty-prints JSON and writes raw bytes for non-JSON
responses.
Verified against live forgejo:
$ fj api repos/public/claude-code-proxy --jq .full_name
public/claude-code-proxy
$ fj api repos/public/claude-code-proxy --json=full_name,description
{ "description": "...", "full_name": "public/claude-code-proxy" }
$ fj api 'repos/public/claude-code-proxy/commits?limit=3' \
--jq '.[] | "\(.sha[0:8]) \(.commit.message | split("\n")[0])"'

Note: `--json=fields` requires the equals sign because the flag has
NoOptDefVal=" " (so `--json` alone is valid for "everything as JSON").
The Example block in --help documents both the `--json=` form and the
`--json-fields` alias which doesn't have that quirk.
Restores installability via 'go install @latest'. Prior letter-suffix
tags (v0.3.0a..v0.3.0f) aren't valid semver and were ignored by Go's
module resolver, leaving @latest pointing at v0.3.0 which predates
the module-path migration.
Add match_dirs field to host config entries for directory-based host
resolution. When no --hostname flag, FGJ_HOST env var, or git remote is
detected, the longest matching directory prefix determines the host.
Symlinks are resolved on both sides for macOS compatibility (/tmp →
/private/tmp). Also adds --limit/-L flag to repo list.
- Add `fgj repo edit` for changing visibility, description, homepage,
and default branch on existing repositories
- Fix `repo create --public` flag which was defined but never read
New commands:
- fgj api: raw REST API passthrough with field inference and path interpolation
- fgj pr diff: view PR diffs with color, --name-only, --stat
- fgj pr comment: add comments to pull requests
- fgj pr review: approve, request changes, or comment on PRs
Agentic enhancements:
- --json-errors flag for structured JSON error output on stderr
- APIError type wrapping HTTP status codes for machine consumption
- Error codes: auth_required, not_found, api_error, invalid_input, etc.
Docs updated for forgejo.zerova.net/sid/fgj-sid fork.
