What it does
I18n Messages is an agent skill from forcedotcom/salesforcedx-vscode. Editing extension i18n message files and their consumers. Use when editing packages//src/messages/i18n.ts, adding/changing nls.localize strings, or choosing placeholder tokens (%s/%d/...).
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Internationalization. It works with Salesforce. The repository describes itself as: Salesforce Extensions for VS Code. The licence is BSD-3-Clause.
When your agent uses it
- Editing packages//src/messages/i18n.ts
- Adding/changing nls.localize strings
- Choosing placeholder tokens (%s/%d/...)
Example prompts
- “/i18n-messages”
What it can do on your machine
Read from SKILL.md and the folder at commit 5972473. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
I18n Messages loads about 855 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 345 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

i18n Messages
Scope:
packages/*/src/messages/i18n.ts+ code consuming those messages vianls.localize- NOT
package.json/package.nls.jsonnls strings (command titles etc.) - NOT unrelated code
Placeholder semantics
nls.localize(key, ...args) substitutes via node:util.format — packages/salesforcedx-vscode-i18n/src/i18n/message.ts:50 (return format(possibleLabel, ...labelArgs)).
| Token | Use | Behavior (node:util.format) |
|---|---|---|
%s | string | string |
%d | count/number | number as-is (3.7→3.7, no truncation) |
%i | integer | truncates float (3.7→3) |
%f | float | float |
%j | value | JSON |
%o %O | value | inspected object |
%c | — | CSS directive, no output |
%% | literal % | % only when args present; bare string skips format() (message.ts:37 args.length > 0 guard) and keeps %% |
%n | NONE | unsupported — renders literal %n, NOT substituted |
Default: counts → %d, strings → %s. (Origin: Removed %n orgs shipped literal %n.)
Arg-count gotcha
message.ts:39 counts specifiers with /%[sdifj%]/g (%% excluded, L40). On mismatch it logs and trims extra args (L41-48); missing args are NOT filled — trailing unmatched tokens render literally.
%o%O%csubstitute at runtime but are NOT in that regex → they escape arg-count validation. Avoid relying on them; prefer%s/%d/%j.%nis not counted and not a real token → expected-count is off by what you intended and the%nprints literally.
Reuse first
grep package.nls.json for an existing equivalent before adding — reuse, don't duplicate.
Per-surface style
From salesforcedx-vscode-org (src/messages/i18n.ts, package.nls.json):
| Surface | Example | Cap | Punctuation |
|---|---|---|---|
Command title (package.nls.json *_text) | SFDX: Create a Default Scratch Org... | Title Case, SFDX: prefix | none (... ok for further input) |
| QuickPick/InputBox placeholder | i18n.ts:67 Select scratch orgs and sandboxes to delete | sentence | none |
| Confirm prompt | i18n.ts:68 Permanently delete %d org(s)? This cannot be undone. | sentence | terminal ./? |
Notification (show*Message) | i18n.ts:92 ... orgs expire in the next %d days. ... | sentence | terminal . |
| Button/action label | i18n.ts:69,70 Delete, Logout | Title Case | none |
| Tree/status-bar label+tooltip | i18n.ts:96 Open Default Org in Browser | Title Case | none |
| Log/channel line | — | sentence | . |
| Validation error | — | sentence | terminal . |
No severity prefix
Don't prefix new strings with Error:/Warning: — the show*Message API supplies severity. i18n.ts:92 (Warning: One or more...) is a legacy anti-pattern; don't copy it, and don't edit it (out of scope). See vscode-window-messages.
Cross-ref
vscode-window-messages covers the notification/button API (which show*Message, return values, Effect, modal). This skill is the message text. Don't duplicate API guidance here.
package.json / package.nls.json command titles, menus, and notification slot keys: command-ui.
