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 | $0.00031 | $0.00999 |
| Opus 5.5 | $0.00012 | $0.00400 |
| Sonnet 5.5 | $0.00006 | $0.00200 |
| Haiku 4.5 | $0.00003 | $0.00100 |
Grade A, and why
envoy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
envoy
Turn a validated research record into a clear manuscript or response. Use for research communication, preserving claim-to-evidence links and explicit author decisions.
Inputs
Claim set and limitations; experiment artifacts; target audience or venue; authorship and submission constraints.
Run record
Use checklist 0.5 or newer for this SOP. Reading or reloading the skill must not reset work. For a new task, run checklist init "${CLAUDE_SKILL_DIR}" --new --path "/absolute/project"; retain its returned ID as RUN. For existing work, use checklist resume "$RUN", then checklist show --run "$RUN". Outside Claude, replace the skill-directory variable with this directory’s actual path.
Commands below record work after it is done. Replace evidence placeholders with concise artifact locations and observations. Manual confirmations are not independent proof; a sensor pass covers only the command and inputs it observed. verify does not close a stage; advance checks that its required readings are fulfilled. Use report --run "$RUN" for the retained history.
Procedure
structure
Identify the reader’s question and organise the argument around supported claims. Separate contribution, method, evidence, and limitations before polishing prose.
Record these artifacts after doing the work:
- Outline connects the contribution to supported claims.
checklist check structure argument --run "$RUN" --evidence "<artifact and observation>" - Each factual claim has an attributable source or experiment artifact.
checklist check structure sources --run "$RUN" --evidence "<artifact and observation>"
When this stage is fulfilled: checklist advance structure --run "$RUN".
draft
Write the argument, figures, and methods with enough detail to inspect or reproduce the work. Verify citations and numeric consistency; never manufacture references, experiments, or author statements.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

envoy is a skill published in the GitHub repository IamK77/Skill (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 31 tokens to every session and 999 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
