IRC Numeric Code Audit — neoirc Implementation Status
This audit catalogs all standard IRC numeric reply codes from RFC 1459, RFC 2812, and common extensions, then checks which are implemented/handled in the neoirc codebase.
Summary
Server-side (Go): Only 3 numeric codes are generated:
372,375,376(MOTD delivery). No other numerics are sent by the server.CLI client (
neoirc-cli): ThehandleDefaultEventcatches all unrecognized commands (including numerics) and displays them generically. No specific numeric handling beyond what the default case provides.Web SPA client (
app.jsx): Explicitly handles375,372,376(renders to Server tab). All other commands (including numerics) fall to adefaultcase that renders to the Server tab.C2S Commands implemented:
PRIVMSG,NOTICE,JOIN,PART,NICK,TOPIC,QUIT,PING/PONGC2S Commands NOT implemented:
MODE,KICK,INVITE,WHO,WHOIS,WHOWAS,LIST(server-side; CLI has local/listvia REST),NAMES(server-side; CLI has local/namesvia REST),OPER,AWAY,USERHOST,ISON,KILL,WALLOPS,SQUIT,CONNECT,DIE,RESTART,REHASH,STATS,LINKS,TIME,ADMIN,INFO,SERVLIST,SQUERY,LUSERS,VERSION,TRACEConnection Registration Numerics (001–005)
Lusers / Server Info Numerics (200–299)
WHO / WHOIS / WHOWAS Numerics (301–319)
Channel / Topic / Names / List Numerics (321–369)
MOTD Numerics (371–376)
Error Reply Numerics (400–502)
Common Extensions / Modern IRC Numerics
Design Notes
neoirc deliberately uses HTTP status codes instead of IRC error numerics for error conditions:
This is architecturally intentional — since neoirc uses HTTP as transport, HTTP status codes are the natural error signaling mechanism.
Score: 3 of ~120 standard numerics implemented
The MOTD numerics (
372,375,376) are the only ones generated server-side. Several IRC features that would normally produce numerics (LIST → 321/322/323, NAMES → 353/366, WHO → 352/315, etc.) are instead served via dedicated REST endpoints that return JSON directly, bypassing the numeric reply system entirely.Recommendations
Connection registration (001–005): Consider sending these on session creation to provide proper IRC semantics. RPL_WELCOME (001), RPL_YOURHOST (002), RPL_CREATED (003), RPL_MYINFO (004), and RPL_ISUPPORT (005) would help clients identify the server and its capabilities.
LUSERS (251–255, 265–266): Could be populated from the existing
GetUserCountdata and sent on connect.NAMES (353/366): Currently served via
/channels/{channel}/membersREST endpoint. Could additionally be sent as numerics on JOIN (standard IRC behavior).TOPIC (332/333): Could be sent on JOIN (standard IRC sends topic on channel join).
Error numerics (400s): The HTTP-status-code approach is clean and appropriate for an HTTP+JSON transport. Adding IRC error numerics would be redundant.
MODE/KICK/INVITE/WHO/WHOIS commands: These would need to be implemented as commands first, then their associated numerics would follow naturally.
AWAY (301/305/306): Would be useful for presence indication.
IRC Numeric Codes Audit
Summary
This audit covers all standard IRC numeric reply codes from RFC 1459 and RFC 2812, plus commonly-used extensions.
schema/numerics/and the README documents it, but the server does not yet send itCurrent state: Only 3 numerics are actually sent by the server (the MOTD set: 375, 372, 376). An additional 14 numerics have JSON schemas and README documentation but are not yet wired into the server code. The README roadmap explicitly lists numeric replies as a TODO item. Errors are currently returned as HTTP 4xx/5xx JSON responses rather than IRC numeric messages.

Quantitative Summary
Recommended Priority
High priority (schemas exist, just need server wiring): 001-004 (welcome burst), 332 (topic on JOIN), 353/366 (names on JOIN), 401/403/433/442 (errors as numerics)
Medium priority (useful once features exist): 005 (ISUPPORT), 322/323 (LIST as numerics), 331 (NOTOPIC), 333 (TOPICWHOTIME), 421/432/461 (error numerics)
Low priority (S2S, OPER, or features not planned soon): All TRACE/STATS, WHO/WHOIS/WHOWAS, ADMIN, LINKS, INFO, OPER, and most channel mode enforcement numerics
make me a PR with the important ones, please. @clawbot
Closing: completed by PR #59 (IRC numerics batch 2 —
internal/irc/package with 60+ named constants, command constants, reply format with code/command fields). Merged by sneak.@clawbot closed incorrectly. there are plenty that are not implemented yet. identify the next batch of codes that we should implement and post it in a comment here.
@clawbot resume working on this, the subagent was killed
Acknowledged — previous audit agent was killed by gateway restarts. Spawning a fresh one to identify the next batch of unimplemented IRC numerics.

Total: 34 numerics implemented.
Defined but NEVER sent (constants exist in
numerics.gobut server never emits them)These are dead code — constants defined but not referenced anywhere in handlers:
Next Batch: Priority Numerics to Implement
These are commonly expected by real IRC clients (irssi, WeeChat, HexChat, Textual, IRCCloud) and their absence causes broken UX or missing features.
Tier 1 — High Priority (clients expect these for basic functionality)
Tier 2 — Medium Priority (needed for feature completeness)
MODE #channel +b(list bans). Constant exists, never sent. Needed once ban management is functional.Tier 3 — New Commands Needed (numerics that require new command support)
Completely Missing Numerics (not even defined as constants yet)
These are standard RFC 2812 numerics that have no constants and no implementation:
account-tagrelated. Modern clients show this.@+) support may be incomplete for IRCv3.Recommended Implementation Order
ok, constants defined but never sent aren't dead code - the module exists as a complete spec reference for anything implementing irc, not just our server. make a PR to add everything in "Completely Missing Numerics" to that module as it should be absolutely spec-complete based on the RFC, and move it from internal/ to pkg/ to indicate its external usefulness/usability.
then make me an issue for adding "Tier 1 — High Priority", and spawn a worker to begin making a PR for it.
