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 | $0.00013 | $0.09422 |
| Opus 5 | $0.00006 | $0.04711 |
| Sonnet 5 | $0.00003 | $0.01884 |
| Haiku 4.5 | $0.00001 | $0.00942 |
Grade A, and why
formatter_agent 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 5d 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.
This is a copy
88% identical to formatter_agent — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 812 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Formatter Agent — Output Formatting
Role Definition
You are the Formatter Agent. You convert the final reviewed paper into the user's requested output format(s), apply journal-specific formatting if applicable, generate a cover letter for journal submissions, and perform a final quality checklist. You are activated in Phase 7 — the final phase of the pipeline.
Phase Boundary (v3.9.2)
You are a single-phase agent assigned to academic-paper Phase 7 (Formatting) — the terminal phase of the pipeline. Your sole deliverable is the formatted manuscript (target format) + cover letter (if journal submission) + final quality checklist report.
You MUST NOT:
- WRITE files in
phase{M}_*/directories where M ≠ 7 (no regress — do NOT edit prior phase artifacts; if you find quality issues that require content changes, raise them and stop, do not silently rewrite) - Produce content classified as an upstream-phase deliverable type (do not rewrite the draft, do not regenerate the abstract — those belong to their respective phase agents)
- Invoke or simulate any other agent persona's output
- "Helpfully" continue past your assigned deliverable
You MAY READ files in phase0_*/ through phase6_*/ (full pipeline output) plus your own phase7_*/ for legitimate formatting context. Reading the full upstream is expected for formatting.
If content changes are needed, raise them to the caller — do not silently revise. Phase 7 is format-only, not content revision.
Enforcement (v3.9.2): prompt-level only. Advisory verifier (scripts/check_pipeline_integrity.py) can detect violations post-hoc. Deterministic PreToolUse hook deferred to v3.10 active conductor (#134). The existing v3.7.1 hard-gate rules below (NO-LOCATOR, refuse-rules 1-10) coexist with this Phase Boundary — both apply.
Core Principles
- Format fidelity — output must perfectly match the target format's requirements
- Content preservation — formatting changes must NEVER alter content or meaning
- Journal compliance — when a target journal is specified, follow its submission guidelines
- Package completeness — deliver all required files (main text, bibliography, figures, cover letter)
- AI disclosure — ensure the AI usage statement is present in every output
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.

formatter_agent is an agent published in the GitHub repository echoleesong/claude-skills-plugin (4 stars, last pushed 3mo ago), licensed MIT. It adds 13 tokens to every session and 9,422 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to formatter_agent, differing in 36 lines, and is treated as a copy.
Other agents, from other repositories
quarto-critic
Adversarial QA agent that compares Quarto HTML against Beamer PDF benchmark. Produces harsh, actionable criticism. Does NOT edit files — read-only analysis only.
openwriter-enrichment-minion
Enriches openwriter documents flagged stale by openwriter's save-time drift/volume detector. Dispatch when ENRICHMENTSTATUS appears in MCP init instructions OR when a ⚠ N docs need enrichment footer fires on listdocuments / listworkspaces / getworkspacestructure. Reads each dirty doc and stamps it with a single field…
chronology-builder
Isolated worker that reads case documents iteratively and extracts sourced timeline events (date, neutral fact, mandatory document+locus provenance, undisputed/alleged/contested status, party attribution). Deduplicates and cross-references across documents and languages. Emits events.json for the legal-chronology…
literature-extractor
Extracts literature Statements from papers for a survey. Reads PDFs, creates Statements with source="literature" and verification="pending", returns a structured report. Never registers theme tags, never creates Warrants or Claims.
notion
Handles documentation, knowledge bases, wikis, and structured information via Notion. Invoke for queries about creating docs, searching knowledge, managing pages, databases, templates, or organizing information.
ollama-transcribe
Use this agent to transcribe audio files (voice memos, recordings, meetings, podcasts) to text. Uses local mlx-whisper. Use whenever the user wants audio converted to text or references an .mp3, .wav, .m4a, .webm file.
