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): The handleDefaultEvent catches 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 handles 375, 372, 376 (renders to Server tab). All other commands (including numerics) fall to a default case that renders to the Server tab.
C2S Commands NOT implemented:MODE, KICK, INVITE, WHO, WHOIS, WHOWAS, LIST (server-side; CLI has local /list via REST), NAMES (server-side; CLI has local /names via REST), OPER, AWAY, USERHOST, ISON, KILL, WALLOPS, SQUIT, CONNECT, DIE, RESTART, REHASH, STATS, LINKS, TIME, ADMIN, INFO, SERVLIST, SQUERY, LUSERS, VERSION, TRACE

Design Notes
neoirc deliberately uses HTTP status codes instead of IRC error numerics for error conditions:
IRC Numeric
neoirc HTTP Equivalent
Used For
401 ERR_NOSUCHNICK
HTTP 404
User/channel not found
403 ERR_NOSUCHCHANNEL

404 ERR_CANNOTSENDTOCHAN

432 ERR_ERRONEUSNICKNAME

HTTP 403
Not a member of channel
451 ERR_NOTREGISTERED
HTTP 401

461 ERR_NEEDMOREPARAMS
HTTP 400
Missing required fields
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 GetUserCount data and sent on connect.
NAMES (353/366): Currently served via /channels/{channel}/members REST 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.

### Design Notes
neoirc deliberately uses **HTTP status codes** instead of IRC error numerics for error conditions:
| IRC Numeric | neoirc HTTP Equivalent | Used For |
|-------------|----------------------|----------|
| 401 ERR_NOSUCHNICK | HTTP 404 | User/channel not found |
| 403 ERR_NOSUCHCHANNEL | HTTP 404 | Channel not found |
| 404 ERR_CANNOTSENDTOCHAN | HTTP 403 | Not a channel member |
| 421 ERR_UNKNOWNCOMMAND | HTTP 400 | Unknown command |
| 432 ERR_ERRONEUSNICKNAME | HTTP 400 | Invalid nick format |
| 433 ERR_NICKNAMEINUSE | HTTP 409 | Nick already taken |
| 442 ERR_NOTONCHANNEL | HTTP 403 | Not a member of channel |
| 451 ERR_NOTREGISTERED | HTTP 401 | Unauthorized |
| 461 ERR_NEEDMOREPARAMS | HTTP 400 | Missing required fields |
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
1. **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.
2. **LUSERS (251–255, 265–266):** Could be populated from the existing `GetUserCount` data and sent on connect.
3. **NAMES (353/366):** Currently served via `/channels/{channel}/members` REST endpoint. Could additionally be sent as numerics on JOIN (standard IRC behavior).
4. **TOPIC (332/333):** Could be sent on JOIN (standard IRC sends topic on channel join).
5. **Error numerics (400s):** The HTTP-status-code approach is clean and appropriate for an HTTP+JSON transport. Adding IRC error numerics would be redundant.
6. **MODE/KICK/INVITE/WHO/WHOIS commands:** These would need to be implemented as commands first, then their associated numerics would follow naturally.
7. **AWAY (301/305/306):** Would be useful for presence indication.

This audit covers all standard IRC numeric reply codes from RFC 1459 and RFC 2812, plus commonly-used extensions.
Implemented -- the server actually sends this numeric via the message queue
Schema only -- a JSON schema definition exists in schema/numerics/ and the README documents it, but the server does not yet send it
Not implemented -- no schema, no server code, not documented
Current 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.

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
## IRC Numeric Codes Audit
### Summary
This audit covers all standard IRC numeric reply codes from RFC 1459 and RFC 2812, plus commonly-used extensions.
- **Implemented** -- the server actually sends this numeric via the message queue
- **Schema only** -- a JSON schema definition exists in `schema/numerics/` and the README documents it, but the server does not yet send it
- **Not implemented** -- no schema, no server code, not documented
**Current 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.

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)
Code
Name
Why it matters
301
RPL_AWAY
When a user is AWAY and someone PRIVMSGs them, the server must send 301 back. Also shown during WHOIS. Without this, AWAY is invisible to other users. Requires implementing the AWAY command.
305/306
RPL_UNAWAY / RPL_NOWAWAY
Confirmation sent to the user when they toggle AWAY status. Clients use these to update their UI (away indicator).
317
RPL_WHOISIDLE
WHOIS idle time and signon time. Every major client displays this. Currently WHOIS is missing idle info.
333
RPL_TOPICWHOTIME
Who set the topic and when. Constant exists but is never sent. Clients display this in channel headers. Should be sent after 332 RPL_TOPIC on JOIN and TOPIC queries.
404
ERR_CANNOTSENDTOCHAN
Must be sent when a user tries to message a channel they can't send to (moderated, banned, not a member). Constant exists, never sent.
411/412
ERR_NORECIPIENT / ERR_NOTEXTTOSEND
Input validation for PRIVMSG/NOTICE. Constants exist, never sent. Clients expect these instead of silent failure.
451
ERR_NOTREGISTERED
Sent when a client sends commands before completing registration (NICK/USER). Constant exists, never sent. Important for connection robustness.
Tier 2 — Medium Priority (needed for feature completeness)
Code
Name
Why it matters
341
RPL_INVITING
Confirmation when you INVITE someone. Requires implementing the INVITE command.
367/368
RPL_BANLIST / RPL_ENDOFBANLIST
Sent in response to MODE #channel +b (list bans). Constant exists, never sent. Needed once ban management is functional.
482
ERR_CHANOPRIVSNEEDED
Sent when a non-op tries op-only actions (KICK, MODE changes, TOPIC on +t). Constant exists, never sent. Critical for channel permission enforcement.
441
ERR_USERNOTINCHANNEL
Sent when KICK target isn't in the channel. Constant exists, never sent. Needed when KICK is implemented.
462
ERR_ALREADYREGISTERED
Prevents double registration. Constant exists, never sent. Minor but good defensive coding.
Tier 3 — New Commands Needed (numerics that require new command support)
Code
Command
Why it matters
302
USERHOST
Used by clients for user/host discovery. Somewhat legacy but still used.
303
ISON
Used by clients for online presence checks. Largely superseded by MONITOR/WATCH but still common.
341
INVITE
Channel invitations — core IRC feature, not yet implemented.
KICK
(various)
KICK command is not implemented. Needs 441, 482 error support.
AWAY
301/305/306
AWAY command is not implemented. Needs the three numerics above.
Completely Missing Numerics (not even defined as constants yet)
These are standard RFC 2812 numerics that have no constants and no implementation:
Code
Name
Why it matters
004
—
RPL_MYINFO is sent but may need format fixes (clients parse this strictly)
252
—
RPL_LUSEROP is sent but 253 RPL_LUSERUNKNOWN is not
321
RPL_LISTSTART
Sent before LIST results. Some older clients expect it. Low priority.
330
RPL_WHOISACCOUNT
Services account name in WHOIS. IRCv3 account-tag related. Modern clients show this.
338
RPL_WHOISACTUALLY
Real host/IP in WHOIS (for opers). Low priority.
353
—
RPL_NAMREPLY is sent but multi-prefix (@+) support may be incomplete for IRCv3.
422
ERR_NOMOTD
Sent when no MOTD file exists. Currently the server always sends an MOTD; if it were empty, clients expect 422 instead of empty 372.
443
ERR_USERONCHANNEL
Target already in channel (for INVITE). Needed with INVITE.
464
ERR_PASSWDMISMATCH
Wrong server password. Needed if PASS is enforced.
671
RPL_WHOISSECURE
Indicates TLS connection in WHOIS. Very commonly shown by modern clients.
Recommended Implementation Order
AWAY system (AWAY command + 301/305/306) — high-impact, frequently used
Wire up dead-code error numerics (404, 411, 412, 451, 482) — already defined, just need to be sent at appropriate points
RPL_TOPICWHOTIME (333) — already defined, just needs to be sent after 332
RPL_WHOISIDLE (317) — needs idle time tracking, but WHOIS feels incomplete without it
RPL_WHOISSECURE (671) — easy to add, modern clients expect it
ERR_NOMOTD (422) — defensive, easy

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)

Total: 34 numerics implemented.
Defined but NEVER sent (constants exist in

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.
