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 | $0.00080 | $0.02185 |
| Opus 5 | $0.00040 | $0.01092 |
| Sonnet 5 | $0.00016 | $0.00437 |
| Haiku 4.5 | $0.00008 | $0.00218 |
Grade A, and why
devin-cli 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 today.
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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Devin CLI (subagent/task delegation)
Documented, not verified. Written from Devin's published CLI docs on 2026-09-06 and not checked against an installed binary. Before trusting any flag here, run
devin --help; on a mismatch use what the binary actually offers and tell the user which line in this file is wrong. This matters more than usual for Devin — see the permission-mode conflict below.
Use Devin CLI to run a separate long-horizon pass over the repo: multi-step implementation, broad refactors, or repo-wide changes—similar to handing a task to a subagent. You stay orchestrator: smaller prompts, less context burn.
When to use Devin CLI
- Large or multi-step work: several files, phases, or checkpoints (feature slice, migration, test suite, docs sweep).
- Repo-wide changes: Devin indexes connected repositories and discovers skills across them.
- Autonomous runs: an
autonomouspermission mode auto-approves everything except file writes, with an OS sandbox enforcing the boundary instead of prompts (requires--sandbox). - Exportable results:
--export out.jsoncaptures a run for later inspection. - User explicitly asks for Devin or "use Devin for this."
When not to use
- Small / single-step tasks answerable with one or two edits or a short explanation.
- Tight feedback loops where the user wants rapid back-and-forth refinement in one thread.
- Secrets or policy-sensitive flows—avoid piping credentials; redact before delegating.
- Already-loaded context where duplicating the whole plan adds no value—handle locally.
- Low ROI (Return on Investment): if the task requires high precision over a single line, or composing the Handoff Table costs more than editing the file yourself. Delegate only when the "mental offloading" outweighs the "handoff overhead."
Delegation and context (critical)
Isolated subagent context saves tokens but splits the story: Devin does not see the main session's full thread. Poor handoffs cause misread subtasks, conflicting assumptions (stack, style, APIs), and wasted edits.
What ships with it
1 file 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.

devin-cli is a skill published in the GitHub repository amirkiarafiei/subagent-cli-skills (5 stars, last pushed 2d ago), licensed MIT. It adds 80 tokens to every session and 2,185 once invoked, about $0.0004 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 2026-09-08.
