feat(doctor): report a CLI older than the plugin, and a statusLine that is not ours - #33
Merged
Merged
Conversation
…at is not ours An empty statusline had two silent causes, and doctor named neither. A cprof older than the installed plugin is the first. The two halves update through different channels — the CLI through Homebrew or the curl installer, the plugin through `cprof update` — so they drift, and the drift hides: an interactive shell may reach the plugin's own copy through a resolver function while every subprocess Claude Code spawns gets whatever PATH holds. A CLI from before 0.13.0 treats `cprof statusline` as an unknown subcommand, writes usage to stderr and exits non-zero, which a statusline renders as nothing at all. doctor now compares the two and names the fix for whichever is behind, and fails while they disagree, because a stale CLI withholds documented features. Version comparison is numeric per segment, since string order ranks 0.9.0 above 0.13.0 — which is how a three-release-old CLI looked current. A version that is not a plain dotted number is never called older, so a dev build produces no advice, and a version is only ever printed once it has parsed: that is what keeps a control byte in a binary's output out of the report. The second cause is a statusLine pointing somewhere else entirely, which cprof could not see. doctor now names the settings file of the profile a session here would use, and reports whether its command references cprof. A wrapper script counts: when the command names a readable file, the check looks inside it one level, so the documented setup — a command line that says only `bash "$HOME/.claude/statusline.sh"` — is recognised by the script's contents instead of being called foreign. The command itself is never echoed back; a JSON string can hold any byte, and the report names the file only. This one does not fail doctor, since running another statusline is a choice. CP_CPROF_BIN joins CP_CLAUDE_BIN and CP_CURL_BIN as a test seam: set and empty means "no cprof on PATH", which a test cannot otherwise arrange on a machine that has one installed. docs/statusline.md gains a section on an empty line, including the one precaution that makes verification trustworthy — `cprof` is often a shell function, so a command must be tested through `sh -c` with a payload on stdin, the way the subprocess will run it, not in an interactive shell where a function hides the failure.

…l skew Review findings on the version check, three accepted and one narrowed. `cp_ver_lt` split versions with `cut -d. -f<n>`, which prints the whole line when the delimiter is absent: a single-component "1" answered "1" for every field, so `cp_ver_lt 1.0 1` called 1.0 the older of two equal versions. It now splits into arrays and compares as many components as the longer side has, which also fixes a version carrying more components than a release ever does — 1.2.3.4.5 and 1.2.3.4.6 compared equal when the loop stopped at four. `doctor` failed for any advisory the check produced, including "could not read the version", which would leave anyone running a dev build with a permanently failing doctor. That state now prints without failing. A plugin older than the CLI keeps failing, the same as the reverse: both halves are one command from current, and doctor already fails on comparable actionable states — an expiring refresh token, a window past 90%. The CLI path in the advisory goes through `cp_path_display`, as every other path shown to a user does. Assertions for each: both directions of 1 against 1.0 and 1.0.1, the five-component pair, the report's exit status for all four states separately from its output, the shortened path, and two doctor integrations for the states that must not fail it.

… does The comment above the call survived from the first commit, when only a stale CLI failed doctor, and sat beside the newer one that describes the actual contract. One comment now, covering either half being older: each carries behaviour the other cannot supply, which is why both fail. Signed-off-by: Diego Cotelo <me@dcotelo.dev>

.statusLine.type equals "command" before checking .statusLine.command, returning
"malformed" for any other type. Add a matching test covering a non-command type
with a command containing "cprof", while preserving the existing classification
for valid command configurations.

Full-review findings. The wiring classifier checked the command without checking the discriminator that decides whether the command runs at all. Claude Code requires `statusLine.type` to be `command`; anything else, or nothing, leaves the statusline unrun however good the command is. A wrong type with a cprof command therefore classified as ours and reported nothing. The type is now checked before the command, so a cprof command cannot mask it, and assertions cover a wrong type, a missing type, and the required type staying silent. docs/statusline.md claimed doctor reports two causes of an empty line. With the malformed diagnostic there are three, so the section now describes it: what `statusLine in <file> is not a command object` covers, and why a type Claude Code does not accept belongs in that list.

…t CodeRabbit approve (#41) * chore(review): assertive profile, and instructions for the untouched trees Closes #37. At `chill`, the incremental review of #33 missed a classifier that ignored `statusLine.type` and so reported a configuration Claude Code would never run as correctly wired. Only an explicitly requested full review found it. The profile goes to `assertive`, with that reason written beside it. Path instructions covered `scripts/**` and `tests/**` only. Four trees had none, and each has conventions a reviewer cannot infer from the diff: - `statusline/**` runs every few seconds inside a live session and must never block, exit non-zero, call the network, or consume stdin unasked. - `hooks/**` degrades to silence and cannot assume cprof is on PATH. - `docs/**` must name only commands and keys that exist, keep anchors resolving across the topic-doc split, and never name another statusline tool; versions are written by automation. - `.github/**` holds write-capable tokens: actions pinned to full SHAs, and no workflow executing a script from the pull request's own revision. The `tests/**` instruction gains the failure mode this repository keeps producing: an assertion that would pass whether or not the code works, with the specific shapes to look for. No linter changes: actionlint, yamllint, markdownlint and gitleaks already default to enabled, and listing only shellcheck under `tools:` never disabled them. Signed-off-by: Diego Cotelo <me@dcotelo.dev> * chore(review): let CodeRabbit approve, so a clean PR needs no admin bypass Closes #36. `main` requires one approving review, and as the sole maintainer every pull request has landed with `--admin` — the rule bypassed rather than met. CodeRabbit reviews every pull request and has found real defects, but submits `COMMENTED` reviews, so its verdict could never satisfy the rule. `request_changes_workflow: true` makes it approve once its comments are resolved and the head has been reviewed. Two things this does not yet know, recorded in the config beside the setting rather than left for someone to rediscover: Whether the approval counts at all. GitHub treats bots inconsistently — Actions reviews count subject to an org toggle, Copilot's explicitly do not. CodeRabbit is a GitHub App with write access, which ordinarily does count, but that is an assumption until a pull request reaches `CLEAN` without `--admin`. This pull request is the first test. Whether an approval survives the release. `dismiss_stale_reviews` is on and `release-bump` pushes `chore(release):` after review, dismissing the approval it just gave. It does re-review a new head; whether it re-approves is unverified. `auto_assign_reviewers` was considered and left off: it assigns suggested reviewers, which on a single-maintainer repository means noise rather than the visibility it sounds like.

A statusline that renders nothing had two causes, and
cprof doctornamedneither. Both came up for real: a statusline was empty, and the reason took a
while to find because nothing in the tool would say it.
A CLI older than the installed plugin
The two halves update through different channels — the CLI through Homebrew or
the curl installer, the plugin through
cprof update— so they drift. Thedrift hides itself: an interactive shell may reach the plugin's own copy
through a resolver function while every subprocess Claude Code spawns gets
whatever
PATHholds. A CLI from before 0.13.0 treatscprof statuslineas anunknown subcommand, writes usage to stderr and exits non-zero, which a
statusline shows as an empty line.
This one fails
doctor: a stale CLI silently withholds features theplugin's own docs describe.
Comparison is numeric per segment, because string order ranks
0.9.0above0.13.0— which is exactly how a three-release-old CLI looked current. Aversion that is not a plain dotted number is never called older, so a dev build
produces no advice, and a version reaches the report only after it has parsed.
That last part is what keeps a control byte in a binary's output out of a
terminal.
A
statusLinethat is not ourscprof could not see what Claude Code's
statusLinewas actually pointed at.Now
doctornames the settings file of the profile a session here would useand reports whether its command references cprof.
statusLine in ~/.claude/settings.json is set but does not reference cprof - see docs/statusline.mdA wrapper script counts. When the command names a readable file the check looks
inside it one level, so the documented setup — a command line that says only
bash "$HOME/.claude/statusline.sh"— is recognised by the script's contentsrather than reported. Without that, this check would have flagged the
configuration this repository itself recommends.
The command is never echoed back: a JSON string can hold any byte, so the
report names the file only. This one does not fail
doctor— running adifferent statusline is a choice.
Also
CP_CPROF_BINjoinsCP_CLAUDE_BINandCP_CURL_BINas a test seam. Setand empty means "no cprof on PATH", which a test cannot otherwise arrange on
a machine that has one installed;
tests/lib.shunsets it so a developer'sshell cannot decide what the fixtures compare against.
docs/statusline.mdgains a section on an empty line, including theprecaution that makes verification trustworthy:
cprofis often a shellfunction, so a command has to be tested through
sh -cwith a payload onstdin, the way the subprocess runs it, not in an interactive shell where the
function hides the failure.
Verification
54 new assertions; the suite is at 1109, up from 1055.
Nine mutations, each caught by the assertion meant to catch it:
cp_ver_lt 0.9.0 0.13.0Removing the character guard from
cp_ver_parseablebreaks three assertionsand makes the shell emit a math error into
doctor's output, which is why theguard is a guard rather than a comment.
One flake of my own, found and fixed before it landed: the no-cprof-on-PATH
test passed only on machines without cprof installed, because
type -Pfoundthe real one. That is what the seam is for.
Suite, shellcheck, manifest checks and a markdown link check over all 16
tracked files: green.
Not in this PR
secrets.TAP_DISPATCH_TOKENdoes not exist, so the release workflow'snotification to the tap is skipped and every release waits for the tap's daily
poll — the tap is at 0.12.0 while 0.13.0 has been published since 12:33Z. That
is why a
brew installtoday can hand someone a CLI without the subcommandthis project documents. Either the secret gets created or the tap's poll moves
to hourly; both live outside this repository.
