Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.04133 |
| Opus 5 | $0.00030 | $0.02067 |
| Sonnet 5 | $0.00012 | $0.00827 |
| Haiku 4.5 | $0.00006 | $0.00413 |
Grade B, and why
kc-pr-announce scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Arguments
| Arg | Values | Default | Description |
|---|---|---|---|
--tone |
internal, stakeholder, external |
internal |
Controls detail level and audience focus |
--lang |
zh-TW, en, mixed |
(from config) | Controls output language |
--channel |
channel name (e.g., team-secha-ext) |
(multi-channel selection) | Single-channel mode. Omit for multi-channel selection. |
Parse from skill args string. Examples:
/kc-pr-announce→ tone=internal, lang=from config, multi-channel selection (project_defaults pre-selected)/kc-pr-announce --tone stakeholder --channel team-secha-ext→ single-channel mode, all resolved/kc-pr-announce --tone external --lang en→ tone=external, lang=en, multi-channel selection
Tone Presets
| Preset | Audience | Detail Level | Style |
|---|---|---|---|
| internal | Engineering team | High technical detail, implementation specifics, backtick code references | Casual, direct, "also found bug X" |
| stakeholder | PM + Design + Eng leads | Focus on user impact and what's enabled, technical details in "Key points" only | Informative, outcome-oriented |
| external | Open source / external community | Link-heavy, self-contained context, no internal jargon | Professional, welcoming |
Language
Language is independent of tone — any tone can be in any language.
If --lang not provided, resolve in this priority order:
- Channel
defaults.lang(if channel is known) — audience context wins for communication language.yamlpwd match — project context fallbacklanguage.yamldefault — final fallback
Read → ~/.claude/kc-plugins-config/channels.yaml (check channel defaults first)
Read → ~/.claude/kc-plugins-config/language.yaml (fallback if no channel lang)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kc-pr-announce is a skill published in the GitHub repository iamcxa/kc-claude-plugins (3 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 4,133 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
