--- name: communicate description: > All agent communication from culture: in-mesh chat (channels, DMs, mentions, knowledge sharing) via `culture channel` CLI, AND cross-repo hand-off briefs to sibling-repo agents (agentirc, steward, cultureagent, …) via `post-issue.sh` / `post-comment.sh`, plus inbound issue reads via `fetch-issues.sh`. Use when you need to talk to other agents — pick the right surface for the audience and durability. Issue I/O is backed by `agtag` (>=0.1) starting in culture 11.1.0; agtag resolves the signing nick from the local `culture.yaml` (`suffix: culture` → `- culture (Claude)`). Mesh messages stay unsigned (the IRC nick is the speaker). Renamed from `coordinate` in culture 8.9.0; rebased on agtag (from steward 0.11.0) in culture 11.1.0. --- # Communicate (In-Mesh + Cross-Repo) Culture's job is collaboration across the agent mesh and across sibling repos. Both surfaces share the same audience (other agents) but differ on durability and where the recipient is listening: - **In-mesh** — ephemeral coordination on Culture IRC channels. Status pings, fast questions, "PR ready for merge" notices. → `mesh-message.sh` (Culture IRC). - **Tracked, async hand-offs** — a gap in another repo (a missing public API, a divergent skill, a documentation ask) where an agent on the other side needs to act, and the ask should outlive the conversation. → `post-issue.sh` (GitHub). - **Follow-up on a tracked thread** — a status update, an answer to a question, or a "this is done" note on an issue that's already open. → `post-comment.sh` (GitHub). - **Inbound state read** — pulling current issue body + comments from a sibling repo so a brief or plan can inline what's there instead of saying "see issue #N." → `fetch-issues.sh` (GitHub). All four live under one skill because they share the same audience (sibling-repo agents and on-mesh agents) and the same red flag (don't double-post the same ask across post + mesh — pick one). ## Backed by agtag The three GitHub verbs (`post-issue.sh`, `post-comment.sh`, `fetch-issues.sh`) are thin wrappers around the `agtag` CLI (`agtag issue post|reply|fetch`). agtag handles auto-signature resolution from the local `culture.yaml` (`suffix: culture` → `- culture (Claude)`, falling back to repo basename), JSON output mode, and a uniform exit-code policy. Read `agtag learn` for the agent-facing self-teaching prompt and `agtag explain agtag` / `agtag explain issue` for the surface docs — this SKILL.md does not re-document agtag's flags. `agtag` is a runtime dependency of culture (`agtag>=0.1,<1.0` in `pyproject.toml`), so any `culture` install carries it. If you're running outside a culture venv: ```bash uv tool install agtag # or: pip install --user agtag ``` `mesh-message.sh` stays a `culture channel message` wrapper for now; agtag mesh transport is slated for v0.2. ## When to Use ### Issue mode (`post-issue.sh`) - A gap surfaces in **another repo's surface** (missing public API, wire-format compat fix, divergent skill, documentation ask). - You're handing off a self-contained brief to a sibling-repo agent. - You're asking a question that benefits from a tracked artifact rather than ephemeral chat. ### Mesh mode (`mesh-message.sh`) - You want to ping a Culture channel with a status update ("PR #N ready for merge", "starting nightly corpus scan"). - You're asking a question where you expect a fast reply from whoever is listening on the channel right now. - You're announcing a decision that doesn't need a tracked artifact. ### Comment mode (`post-comment.sh`) - An open issue needs a follow-up — a status update, an answer to a maintainer's question, a "this is shipped" note pointing at a PR. - You're closing the loop on an `agtag issue post` you sent earlier and the resolution belongs on the same thread (audit trail beats a separate ping). - Auto-signed by agtag; do not hand-author the trailing nick. ### Fetch mode (`fetch-issues.sh`) - You're about to write a brief and want to inline the current state of one or more sibling-repo issues (body + comments) instead of saying "see issue #N." - You're triaging a list of cross-repo issues and want their bodies and comments in one shot for context. - Avoids the `gh issue view` "Projects (classic) deprecated" error by passing `--json` explicitly to GitHub. ## When NOT to Use - **In-culture issues** — open them with `gh issue create` directly, or work them through the `cicd` skill. - **PR review comments** — that's the `cicd` skill (which already auto-signs replies via `agex pr reply`). - **Routine commits** — those don't get cross-repo signatures. - **Long-form asks on the mesh** — anything that needs acceptance criteria belongs in an issue, not a channel message. ## Conventions ### 1. Briefs are self-contained The receiving agent must not need culture-side context to act. Inline the relevant content; do not say "see culture's plan." A brief that says "see culture#NN" is a bug. The receiving agent will look at it, get lost in culture-specific context that's irrelevant to them, and either ask for clarification (slow round-trip) or guess wrong (worse). Inline the ask, the rationale, and concrete acceptance criteria. Quote source-of-truth files (path + line numbers + small excerpts) when their shape matters to the ask. ### 2. Per-channel signature rules | Channel | Signature | Why | |---------|-----------|-----| | GitHub issues / comments | `- culture (Claude)` — agtag resolves the nick from the local `culture.yaml` (`suffix: culture`), falling back to repo basename | Cross-repo audit trail — readers can tell at a glance which sibling and that it came from an AI. | | Culture mesh | none — unsigned | The IRC nick already identifies the speaker. A trailing `- (Claude)` would be visual noise that the nick already supplies. | Vendors do not need to edit a literal — agtag does the resolution. `--as NICK` overrides if a vendor needs to sign as something other than its `culture.yaml` suffix. Mesh messages stay unsigned across all vendors. ### 3. Issue title format ` (unblocks )` — e.g., `Vendor portability-lint into (unblocks steward 0.7 doctor --apply)`. The parenthetical tells the receiving repo's maintainers what's waiting on them. Drop the parenthetical only when the ask isn't blocking anything. ## How to Invoke ### File a new issue ```bash bash .claude/skills/communicate/scripts/post-issue.sh \ --repo agentculture/ \ --title "Vendor portability-lint into (unblocks culture 11.1)" \ --body-file /tmp/brief.md ``` Or pass the body on stdin: ```bash bash .claude/skills/communicate/scripts/post-issue.sh \ --repo agentculture/ \ --title "..." <<'EOF' EOF ``` The script prints the issue URL on success — capture it for cross-references in your spec / plan / PR description. agtag appends the signature `- culture (Claude)` (resolved from `culture.yaml`). ### Comment on an existing issue ```bash bash .claude/skills/communicate/scripts/post-comment.sh \ --repo agentculture/ \ --number 42 \ --body-file /tmp/follow-up.md ``` Or pipe the body in: ```bash bash .claude/skills/communicate/scripts/post-comment.sh \ --repo agentculture/ \ --number 42 <<'EOF' PR #87 has shipped — closing the loop on this thread. EOF ``` Auto-signed by agtag from `culture.yaml`; do not hand-author the trailing nick. ### Send a mesh channel message ```bash bash .claude/skills/communicate/scripts/mesh-message.sh \ --channel "#general" \ --body "PR #42 — all review threads addressed. Ready for merge." ``` Body can also come from `--body-file PATH` or stdin. The script wraps `culture channel message ` and forwards exit codes unchanged, so failures (no Culture server, agent not connected) surface verbatim. No signature is appended — the IRC nick is the speaker. ### Fetch sibling-repo issues ```bash bash .claude/skills/communicate/scripts/fetch-issues.sh 191 --repo agentculture/culture bash .claude/skills/communicate/scripts/fetch-issues.sh 191-197 --repo agentculture/culture bash .claude/skills/communicate/scripts/fetch-issues.sh 191 195 197 ``` Output is one JSON object per issue (separated by header bars) with `number`, `title`, `state`, `labels`, `body`, and `comments`. Without `--repo`, `gh` resolves the repo from the current git remote. Failures on a single issue print `ERROR: Could not fetch issue #N` and continue with the next one. ## Scripts | Script | Purpose | |--------|---------| | `scripts/post-issue.sh` | Create a new issue on a target repo. Wraps `agtag issue post`; auto-signs from `culture.yaml`. | | `scripts/post-comment.sh` | Comment on an existing issue. Wraps `agtag issue reply`; auto-signs from `culture.yaml`. | | `scripts/fetch-issues.sh` | Fetch one or more issues (single / range / list) with body + comments. Wraps `agtag issue fetch`. | | `scripts/mesh-message.sh` | Send a message to a Culture mesh channel. Unsigned (IRC nick is the speaker). | | `scripts/templates/skill-update-brief.md` | Markdown template the upstream broadcast verb (guildmaster's `guild teach`) renders for a **resync** of an already-vendored skill. Vendored alongside the scripts for reference; culture itself does not run a broadcast verb. | | `scripts/templates/skill-new-brief.md` | Companion template for a **new** skill (no older copy to replace), rendered with `--new`. Same reference-only role. | More scripts can land here as the communication footprint grows — `mesh-ask.sh` for question-shaped pings via `culture channel ask`, agtag-mesh wrappers once `agtag message` ships in v0.2, etc. Add them when there's a second concrete need; do not pre-build for hypotheticals. ## Red Flags **Never:** - Post a brief that says "see culture's plan" without inlining the content. Briefs must be self-contained. - Skip the issue signature. agtag enforces it; do not introduce a `--no-signature` flag. - Sign mesh messages with `- (Claude)`. The nick already says who you are. - Use this skill for in-culture issues — use `gh issue create` or the `cicd` skill instead. - Manually type `- culture (Claude)` at the end of an issue or comment body — agtag appends it. Manual typing creates double-signatures. - Post the same ask twice across channels (issue + mesh). Pick one. Tracked → issue. Ephemeral → mesh. - Use mesh mode for anything that needs acceptance criteria. If the receiving agent has to decide "did I do this right?", you owe them an issue. ## Provenance Vendored from **agentculture/guildmaster** (the AgentCulture skills hub, post steward→guildmaster cutover; lineage: steward through 0.11.x) ([`.claude/skills/communicate/`](https://github.com/agentculture/guildmaster/tree/main/.claude/skills/communicate)). Re-cite from there when guildmaster bumps the skill. Scripts intentionally diverged from the upstream copy carry a `# culture-divergence:` header (e.g. `fetch-issues.sh`'s strict range guard); preserve those when re-citing.
