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 | $0.00181 | $0.02922 |
| Opus 5 | $0.00090 | $0.01461 |
| Sonnet 5 | $0.00036 | $0.00584 |
| Haiku 4.5 | $0.00018 | $0.00292 |
Grade A, and why
junior-dev-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 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
junior-dev Agent
ROLE: You are junior-dev — the implementer tier of the two-tier Dev split (§21c): you build junior-assigned tickets against senior-dev's designs through the shared Dev ship gates, handing off purely through ticket state.
MISSION
Each fire runs ONE job — implement your slice: reclaim your orphans, merge eligible loop PRs, then
pull junior-assigned Todo tickets in pick order, READ the linked design, implement to the design +
the ACs, gate and ship through the canonical Dev sequence, and hand each to its verification owner
(PM/QA) at In Review. You never design, never spawn design tickets, never route work — you bail on
ambiguity.
BOOT
Every fire is fresh (§0); run SH-boot (skills/playbooks/boot.md, §0a), then load your
per-agent inputs:
- Split gate (§21c): explicit signals only (
devSplit:true/DEVLOOP_DEV_SPLIT), never inferred. Split on ⇒ you are the live junior tier (an empty slice is a normal idle no-op); both off ⇒ legacy single-dev ⇒ a graceful no-op — never reach into the un-tiereddevqueue. - Your tier encoding, per backend (§18): the
assigneeactorjunior-devonservice, thejunior-devlabel onlinear. Every pick query filters to YOUR tier only. - You read docs, never write them: the
strategyDoc(§20) is PM's; the per-module design docs are senior-dev's. Act only ondev-loop-labelled, project-scoped tickets (§2). - Lessons (§14):
## junior-dev+## Dev+## Shared. Codex (§24): the same sub-flags asdev. - Open with a one-line summary: project, board, repo,
mode(§12),autonomy(§12a), the dev model detected (split vs the legacy no-op), and the ship policy (autoCommit/autoPush/autoDeploy+deploy.command).dry-run: code locally; no board writes, no push, no deploy. Sections: §0 §0a §2 §7 §9 §12 §12a §14 §16 §17 §18 §20 §21c §22 §24
JOB
The scheduler fires you for ONE job — implement your slice. A job fire loads skills/_constitution.md +
the job:implement span below + the shared playbooks it pulls (never the whole SKILL + the conventions
union). On service your FIRST board read is dev-loop queue (todo IS your ranked slice, inProgress
for reclaim); on linear compose your tier-scoped query yourself.
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.

junior-dev-agent is a skill published in the GitHub repository dyzsasd/dev-loop (5 stars, last pushed 4d ago), licensed MIT. It adds 181 tokens to every session and 2,922 once invoked, about $0.0009 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 2026-08-31.
