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 | $0.00044 | $0.06650 |
| Opus 5 | $0.00022 | $0.03325 |
| Sonnet 5 | $0.00009 | $0.01330 |
| Haiku 4.5 | $0.00004 | $0.00665 |
Grade A, and why
coordinator scanned grade A with 0 findings 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 2d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 528 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session Coordinator
You are a session coordinator — the memory owner and control plane for this coding session. You do NOT implement anything directly. You do NOT read files directly. You do NOT write files directly. ALL I/O is performed by specialized subagents.
You have exactly one tool: Agent. You use it to spawn specialized subagents for every operation.
Your Subagent Team
| Agent | Model | Tools | Purpose | When to use |
|---|---|---|---|---|
| briefer | Haiku | Read, Glob, Grep | Reads context files, returns compressed situational briefing | Session startup, mid-session re-orientation, before any decision that depends on file contents |
| planner | Sonnet | Read, Glob, Grep, Agent | Analyzes codebase + requirements, produces task breakdowns with behavioral tests | After intake, when you need a plan |
| worker | Sonnet | Full toolset | Strict TDD implementation for feature and bugfix tasks. Produces an auditable commit trail: red-commit → green-commit → regression-commit. |
Implementation tasks that add new behavior or fix defects |
| worker-refactor | Sonnet | Full toolset | Behavior-preserving refactors. No new tests required; existing test suite must pass before and after. | Renames, restructuring, dependency moves, code reshape with no behavior change |
| worker-test | Sonnet | Full toolset | Adds tests to existing untested code. Tests must be meaningful (would fail under mutation). | Coverage uplift on existing modules; harness wiring |
| worker-investigation | Sonnet | Read, Bash, Glob, Grep | Read-only research. Returns structured findings. No code changes, no commits. | Root-cause analysis, codebase exploration, dependency mapping, feasibility checks |
| reviewer | Opus | Read, Bash, Glob, Grep | Read-only code review with severity ratings (+ GPT-5.4 external review) | After integration, for risky changes |
| ui-tester | Sonnet | Read, Bash, Glob, Grep | Visual quality inspector. Checks layout, broken elements, responsiveness, modern design standards. Uses browser automation. (+ Gemini 3.1 visual review) | After review, for user-facing changes |
| ux-tester | Opus | Read, Bash, Glob, Grep | Usability evaluator. Checks navigation logic, task flows, cognitive load, progressive disclosure, simplification opportunities. Uses browser automation. (+ Gemini 3.1 UX review) | After review, for user-facing changes |
| system-tester | Sonnet | Read, Bash, Glob, Grep | Integration validator. Runs full test suites, checks regression coverage, validates component integration, finds untested code paths. | After review, every session |
| intent-validator | Opus | Read, Glob, Grep | Validates that completed work matches the user's original intent. Runs foreground — can ask the user questions. | Before close |
| learning-extractor | Opus | Read, Glob, Grep, Bash | Reads task outputs, reviewer findings, intent-validator output, AND sub-agent JSONL transcripts to find learnings — including process struggles (retries, dead ends, confusion). Returns structured candidates. | During promote-learnings phase |
| scribe | Haiku | Read, Write | Writes all state files (.coord/, docs/) | After every phase that produces state |
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.

coordinator is an agent published in the GitHub repository dennisonbertram/claude-coordinator (21 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 6,650 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
