What it does
Coordinator Source Of Truth is an agent skill from kubefleet-dev/kubefleet. The complete file-by-file source-of-truth hierarchy for Squad: which files are authoritative, which are derived/append-only, who may write each one, who may read each one, and the precedence rules when they conflict. Squad coordinator loads this on demand when it needs to resolve a write conflict, decide where a piece of state belongs, or answer a 'who owns this file' question.
Its SKILL.md is about 1.5k 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 Agent Workflows. The repository describes itself as: KubeFleet is an open-source Kubernetes multi-cluster application management solution. The licence is Apache-2.0.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “who owns this file”
- “/coordinator-source-of-truth”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- If squad.agent.md and any other file conflict, squad.agent.md wins. It is the only file with hard governance authority.
- Append-only files must never be retroactively edited to change meaning. They are diagnostic and audit-trail material. Corrections go in a…
- Agents may only write to files listed in their "Who May Write" column above. Violations are a contract bug; runtime state-backends will…
- Non-coordinator agents may propose decisions in their responses, but only Squad (Coordinator) records accepted decisions in…
What it can do on your machine
Read from SKILL.md and the folder at commit 58812a2. 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
Coordinator Source Of Truth loads about 1.5k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 572 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.

Load this skill when: the coordinator (or any agent) needs to resolve a "where does this state belong?" or "who is allowed to write this file?" question — e.g., when about to write
.squad/decisions.md, when reviewing whether an agent broke the append-only rule, when answering a user question about Squad's file layout, or when adjudicating a conflict between two files. The short summary insquad.agent.mdis for routing; this skill is the full reference.
State backend note
Files below marked as "Derived / append-only" are mutable state — agents access them with runtime state tools (squad_state_read, squad_state_write, squad_state_append, squad_state_delete, squad_state_list). The runtime decides whether the configured backend stores them on disk, git-native state, or an external provider. Files marked as "Authoritative" are static config and always live on disk regardless of backend.

Rules
- If

- Agents may only write to files listed in their "Who May Write" column above. Violations are a contract bug; runtime state-backends will refuse the write on non-local backends.
- Non-coordinator agents may propose decisions in their responses, but only Squad (Coordinator) records accepted decisions in
