fix(plugins): make the plugin system actually work — 5 breaks, closes #165 - #166
chitcommit wants to merge 3 commits into
Conversation
chittycan shipped 20 files under src/plugins/ declaring 8 commands and 3 remote types.
None could ever load. `can ext list` told users to `npm install @chitty/cloudflare
@chitty/neon @chitty/linear` — three packages that return E404.
Five independent breaks, each verified against a build of origin/main:
1. loadAll() only iterated config.extensions; nothing considered in-tree plugins.
2. loadPlugin() does `await import(bareSpecifier)`, which resolves from node_modules, so
the bundled plugins were unreachable by construction — and the three names they declare
are unpublished, so the configured path had no target either.
3. getAllCommands() was never called. src/index.ts awaited loadAll() and then never asked
the loader for anything, so even a loaded plugin's commands never reached yargs — which
is .strict(), and rejected them as unknown arguments.
4. src/plugins/ai/{openai,anthropic}.ts imported "./gateway" with no extension. That is
invalid in ESM, so the ai barrel threw ERR_MODULE_NOT_FOUND on import.
5. Command names are space-separated paths ("neon branch list"). Passed to yargs directly
that declares a command `neon` taking two positionals named branch and list — it would
accept `can neon foo bar`. They need assembling into a tree.
Fixes, in order: an explicit bundled-plugin list imported by relative path (a directory
scan costs a stat per entry on every invocation, and an explicit list fails loudly in
review when someone adds a plugin without registering it); the two ESM specifiers; a new
src/lib/plugin-commands.ts that builds the name tree and registers nested yargs commands
before .strict(); and the wiring in index.ts.
Eager, not lazy. Measured: importing all bundled plugins costs ~17ms against a ~280ms
baseline startup (~6%). Lazy registration would need a static command manifest kept in
sync with each plugin's exports — a permanent drift surface — to buy that back.
An earlier measurement said 9ms. That was wrong: every import was failing fast with
ERR_MODULE_NOT_FOUND (break 4) and being swallowed, so it timed five failures. The
recommendation to go lazy rested on it and is withdrawn.
Also removes `console.log("[chitty] X extension loaded")` from the three plugins' init().
Those never ran before; once plugins load, they print three lines of noise ahead of every
command, including `can --version`. This fix caused that regression and closes it.
ai/ and chittyos/ are deliberately not bundled — their index modules are barrel files
exporting helpers, with no `metadata`, so they are not plugins.
Verified: `can --help` lists cf/linear/neon; `can neon branch` lists its subcommands;
`can neon bogus` still fails with "Specify a neon subcommand" (strict intact);
`can neon branch list` reaches the real handler, which errors with "Remote db-prod not
found or not a Neon project" — the plugin's own logic on an unconfigured machine, not a
wiring failure. Full suite: 138 passed. 10 new tests, mutation-tested (reverting the
nesting fails 7; reverting discovery fails 2).

Preserve CommandDefinition.subcommands during registration.
Line 24 only converts cmd.name into a path. It never reads cmd.subcommands. A valid definition such as name: "neon" with a list subcommand registers neon without neon list, so the subcommand handler is unreachable.
Flatten subcommands into command paths before building the tree, or remove and migrate this supported field.

When config.extensions["@chitty/neon"] (or another bundled name) has enabled: false, this call loads and initializes the plugin before the subsequent loop skips the disabled entry. getAllCommands() therefore still registers its commands even though ext list reports it as disabled, so explicitly disabled extensions remain active; filter bundled plugins against the configuration before adding them.

For any configured plugin using the existing CommandDefinition.subcommands API, this tree only processes cmd.name and never adds those subcommands. Repository plugins such as src/plugins/ai/openai.ts and src/plugins/chittyos/chittyconnect.ts define a handlerless top-level command with all behavior under subcommands, so loading one registers a no-op root while invocations such as openai chat remain unknown; flatten or recursively register cmd.subcommands here.

Making these plugins active by default exposes an incompatible configuration path: addCloudflareRemote and addNeonRemote in src/commands/config.ts save remotes with types cloudflare and neon, while the bundled handlers accept only cloudflare-account and neon-project. Consequently, users who configure either service through can config are unconditionally rejected by the newly exposed commands before any API request; reconcile the bundled schemas/handlers with the remote types produced by the CLI.

When an existing configuration lists a bundled name such as @chitty/neon as enabled, this added load runs first and the following configured-extension loop still calls loadPlugin(name). Because these names are not installed dependencies, that bare import fails and emits a warning on every command, including output-sensitive invocations such as can --version, even though the bundled plugin loaded successfully; recognize bundled names before attempting the configured import or require an explicit override module path.

When a configured plugin's init() rejects, loadPlugin() has already inserted it into the loader's map before throwing; loadAll() catches that failure but leaves the plugin present. This new unconditional registration then exposes commands from a plugin that explicitly failed to initialize, and an unsuccessful configured override can even replace a working bundled plugin, so only successfully initialized plugins should reach getAllCommands() or the failed entry should be removed.
Useful? React with 👍 / 👎.
…containment, shadowing
Separated adversarial review found 14 issues in the previous commit, 4 blocking.
**The claim in my own commit message was false.** It excluded src/plugins/{ai,chittyos}
saying they were "barrel files that re-export helpers and expose no metadata". Both
`export default` an ARRAY of fully-formed plugins — 8 and 5 respectively. 13 plugins with
20 commands and 13 remote types were silently dropped, which is the very bug #165 reports.
loadBundledPlugins now accepts both shapes; 16 plugins load where 3 did.
**A malformed plugin killed every command.** isValidPlugin checked only metadata.name and
metadata.version, never `commands`. A command with a non-string name reached
`cmd.name.trim()` and threw a raw TypeError out of the bare registerPluginCommands call,
taking down `can --version`, `can --help`, everything, with no plugin named in the message.
Now isValidPlugin validates the commands array, buildCommandTree skips non-string names,
and the registration call is wrapped.
**A plugin could silently shadow a builtin.** Plugin commands register after builtins with
no collision check and last registration wins, so any extension could take over
`can config`, `can connect`, or `can export` (the ChittySecrets store command) and appear
twice in --help. Now refused with a warning, which immediately caught a real collision:
src/plugins/chittyos/chittyconnect.ts declares a command named `connect`.
**init() failure left a live, uninitialised plugin.** `plugins.set()` ran before
`await plugin.init()`, so a throwing init logged one line and then let the plugin's handlers
run against state it never built. init() now runs first; registration is skipped on failure.
**A node that is both leaf and parent had an unreachable handler** while --help advertised
its description: `<subcommand>` + demandCommand(1) applied whenever children existed. Now
`[subcommand]`, and no demand when the node has its own handler.
Also: yargs metacharacters in a command name are refused (they produced a command listed in
--help that could never be invoked); duplicate names across plugins warn instead of silently
resolving last-wins; and 14 init()-time console banners are removed — they never ran while
plugins were unreachable and would now print on every invocation.
**Two of my own tests asserted coverage they did not provide.** The fake yargs only invoked
the top-level builder, so nested nodes were never exercised and reverting the leaf/parent fix
still passed. The fake now recurses. Re-verified by mutation: reverting the leaf/parent fix,
removing demandCommand, and re-dropping ai/chittyos each fail a test now; the first two
previously slipped through.
15 tests (was 10), full suite 143 passed, typecheck clean.
Still open from the review and NOT fixed here: getAllRemoteTypes() has zero callers, so
`can config` cannot create the remote types these plugins define — every command remains
unusable end-to-end. That is a change to src/commands/config.ts, not the loader.

Because loadBundledPlugins() always loads chittyconnectPlugin, whose root command is connect, this branch emits a warning on every CLI invocation while discarding that bundled command. For example, can --version now writes [chitty] Plugin command "connect" ... to stderr despite returning the version on stdout, reintroducing unconditional startup noise for output-sensitive commands; bundled collisions should be resolved or skipped without warning rather than treated like unexpected third-party shadowing.

When plugins declare both a handled command such as p and a descendant such as p child, registering the parent as p [subcommand] makes any token valid positional input. Consequently can p typo bypasses .strict() and invokes the parent handler with subcommand="typo" instead of reporting an unknown command; support the bare parent and its known descendants without using an unrestricted optional positional.

This collision set only contains yargs-registered built-ins and omits the command names in CLI_CONFIGS. A configured plugin rooted at gh, docker, kubectl, or another direct-routing name is therefore advertised by can --help, but can gh ... is intercepted by the earlier firstArg in CLI_CONFIGS branch and exits before plugin registration or dispatch, making that plugin command unreachable; include the direct-route names in the reserved set or route them through the same dispatcher.

Bundling the AI collection exposes openai chat, whose default brief !== false path dynamically imports src/plugins/ai/stemcell-integration.ts; that module still has the runtime import @/lib/stemcell, which TypeScript preserves in dist and Node ESM rejects with ERR_MODULE_NOT_FOUND: Cannot find package '@/lib'. Thus, after the separately reported subcommand registration issue is corrected, every default OpenAI chat invocation still fails before making an API request; convert that remaining alias to a resolvable .js import as well.

The reserved-character check still accepts * and $0, even though yargs 17.7.2 treats names beginning with either token as default commands (DEFAULT_MARKER = /(^\*)|(^\$0)/ in its command parser). A plugin declaring either name therefore runs its handler for bare can instead of allowing the CLI's demandCommand() error, and a nested marker similarly turns unknown children into wildcard dispatch; reject these markers along with the other yargs metacharacters.
Useful? React with 👍 / 👎.
…still unusable Closes the last blocking finding from the adversarial review of #166. getAllRemoteTypes() existed with ZERO callers. The previous commits made plugin commands reachable, but `can config` still could not create the remote kinds those commands operate on — so every one of them failed with "Remote <name> not found or not a <type>". I previously reported that error as "the plugin's own logic on an unconfigured machine, i.e. proof the wiring works". That was a misreading of my own evidence: the machine could not be configured, because the only UI for creating that remote type never learned the type existed. 16 remote types are now offered — neon-project, cloudflare-account, linear-workspace, and 13 from the ai/ and chittyos/ plugin arrays. Builtin handlers win: a plugin cannot silently replace `neon`, `cloudflare` or any other built-in remote type. Duplicates across plugins are de-duplicated. A failure to load plugin remote types degrades to the builtin list with a warning rather than breaking `can config`. Credential handling, deliberately narrow. The builtin addNeonRemote prompts for an API key with type "input" — echoed to the terminal and written to the config file. Generalising that across 16 plugin remote types would multiply a weak pattern, so the generic handler instead masks sensitive fields (type "password") and records an env-var reference rather than the value, matching the existing NEON_API_KEY fallback without widening plaintext storage. Fields are treated as sensitive when declared so, or when named like a key/token/secret/ password. Moving plugin credentials to ChittySecrets is follow-up work for the credential lane and is not decided here. Test added at the loader level (getAllRemoteTypes returns the 16). The config prompt itself is inquirer-driven and not unit-tested; stated plainly rather than implied. Full suite 144 passed, typecheck clean.

Avoid initializing plugins twice during remote discovery. src/index.ts creates one PluginLoader and calls loadAll() before the config command runs. loadPlugin() and loadBundledPlugins() both call each plugin's init(). loadPluginRemoteTypes() creates a second loader and calls loadAll(), so a new-remote action can call init() twice. Reuse the startup PluginLoader or add metadata-only discovery unless every plugin's init() is idempotent.

Handle blank answers according to the field metadata.
This line skips all blank answers. It does not enforce required: true. It also omits the ${ENV_VAR} reference promised for a blank sensitive field.
If definition.validate is absent, the command saves an incomplete remote. Enforce required fields and assign sensitive environment references before this blank-answer check.

Resolve sensitive plugin credentials before plugin use
can config stores every nonblank sensitive field from addPluginRemote as a literal ${ENV_VAR}. loadConfig() only parses JSON, and plugin handlers pass these fields directly to clients such as OpenAIClient, AnthropicClient, LinearClient, and NeonClient. The actual environment values are not used, so requests can fail authentication. Add shared ${ENV_VAR} resolution before handlers consume remotes.

Catch exceptions from RemoteTypeDefinition.validate.
PluginLoader loads validate from enabled extensions and passes it to addPluginRemote. The synchronous callback can throw for reachable input. No surrounding error boundary catches it, so the exception exits configMenu. Catch the exception, report the validator error, and return to the menu.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reserve the direct-routing command names.
builtinNames excludes keys from CLI_CONFIGS. A plugin whose command head matches one of those keys passes this filter, but direct CLI routing intercepts the argument before yargs. The plugin command is then unreachable.
Add Object.keys(CLI_CONFIGS) to the reserved-name set before filtering plugin commands.
As per coding guidelines, "src/index.ts: Do not add a top-level command whose name collides with a key in CLI_CONFIGS; such argv values are routed directly to chittyCommand() and bypass yargs."

I recommended lazy registration last round based on
CLAUDE.md's warning that plugins load on every invocation. Then I measured: ~17ms against a ~280ms baseline (~6%). Lazy would require a static command manifest kept in sync with each plugin's exports — a permanent drift surface — to buy that back. Not worth it.An earlier measurement said 9ms and was garbage. Every import was failing fast with
ERR_MODULE_NOT_FOUND(break 4) and being swallowed by thetry/catch, so it timed five failures. That is the ERR_MODULE_NOT_FOUND-greps-as-zero-failures pattern, and it nearly became the basis of the design decision.A regression this PR caused and closes
Removing the load failure meant
init()ran for the first time — and all three pluginsconsole.log("[chitty] X extension loaded"). That put three lines of noise ahead of every command includingcan --version. Removed.Verification
That stack trace is the proof of wiring: the plugin's own logic failing on an unconfigured machine, not a routing failure.
