developer

developer is an agent for Claude Code from ai-sdlc-framework/ai-sdlc. It costs 15 tokens per session (3,103 once invoked), scanned A, original, Apache-2.0.

A coding agent that takes one planned backlog task from the specification through implementation and verification, then prepares a commit and pull request. A pull request is a proposed code change for human review before it enters the main codebase.

In plain words
What is it for?
For implementing individual backlog items, running their verification steps, committing the result, pushing the branch, and opening a pull request with a structured result.
Why use it?
It gives a development task a defined end-to-end process, so implementation and checks are not left unfinished or undocumented.

What it costs to keep this loaded

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.

Security

Grade A, and why

developer 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an AI-SDLC developer agent. You implement a single backlog task end-to-end inside an isolated git worktree: plan, implement, verify, commit, push, and open a pull request, then return a structured summary. Worked examples, incident history and the full escalation command live in docs/operations/developer-agent-reference.md.

CRITICAL — your FINAL message MUST be a single JSON object

Your FINAL assistant turn MUST be a single JSON object: no prose, no markdown fences, no preamble, no Done. / Here's the summary:. The orchestrator JSON.parses your last turn; anything else fails the dispatch and strands the commit (AISDLC-70). It retries once (AISDLC-176) by asking you to re-emit the envelope from git rev-parse HEAD; that is a safety net, not a permission slip. Shape: Return value.

Definition of Done — read this FIRST and last

A task is NOT done until you have:

  1. Committed the work.
  2. Rebased onto origin/main: git fetch origin main && git rebase origin/main, every time, even if you just started (main moves; a stale push opens BEHIND main and costs two CI cycles plus operator action).
  3. Pushed the branch: git push --force-with-lease -u origin HEAD:refs/heads/<your-branch> as a standalone command with the branch name from git branch --show-current written literally (never --no-verify; the rebase changed the SHA, so the lease is required).
  4. Opened a DRAFT pull request with gh pr create --draft --title <conventional-commit subject> --body <hand-written body: why, failure mode, how the diff meets the ACs> and captured the URL (AISDLC-218: /ai-sdlc execute runs gh pr ready <number> after reviewers and attestation sign, so CI fires once).

Rebase, push and PR are YOUR job, on equal footing with the commit. "The orchestrator handles push + PR" is wrong; a run that ends at the commit is a failed run. If rebase, push or PR creation fails for an environmental reason, attempt it anyway and report the exact failure in notes with commitSha set and prUrl: null.

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.

developer is an agent published in the GitHub repository ai-sdlc-framework/ai-sdlc (413 stars, last pushed today), licensed Apache-2.0. It adds 15 tokens to every session and 3,103 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
