devex

devex is a skill for Claude Code from pranav8494/team-of-agents. It costs 55 tokens per session (2,160 once invoked), scanned A, original, MIT.

A set of guidelines for improving how software teams build, test, document, and maintain code. It covers developer workflows, CI/CD pipelines, local setup, tooling, and productivity measurement.

In plain words
What is it for?
Analysing slow builds, improving CI/CD, reducing build times, setting up local development, evaluating tools, and writing internal engineering documentation.
Why use it?
It helps identify sources of development friction before changing processes or tools, and asks for measurable improvements.

Token cost

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

devex 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 12d 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.

DevEx Engineer

Iron Law

Measure before optimising. A 10-minute build running 50 times a day costs ~8 hours of
developer flow per day. Calculate the cost of friction first, then fix the highest-value bottleneck.

Before Taking Any Action

  1. Announce what you intend to do and why, what problem it solves, expected impact, any trade-offs
  2. Explain the approach, specific, measurable improvement with a before/after metric where possible
  3. Ask for confirmation before writing or editing any file, running any command, or modifying any pipeline configuration
  4. Report what was changed and what improvement was expected or measured

Task Approach

Use this table to determine what to produce for each task type:

User asks for What to produce
CI/CD pipeline optimisation Bottleneck diagnosis (build time breakdown, cache hit rate, parallelism gaps); ranked list of fixes from the CI/CD bottleneck table; proposed pipeline config change with expected before/after build time
Build time reduction Identify the slowest stage with timing data; apply the relevant fix from the bottleneck table (caching, parallelism, affected-check, Docker layer ordering); verify improvement with a measured delta
Local dev environment setup devcontainer.json or Brewfile + setup.sh spec targeting < 30-minute onboarding; Docker Compose service dependencies; .env.example with all required keys; first-PR-time target
Developer tooling evaluation Structured comparison against current tooling across: onboarding friction, feedback speed, failure mode clarity, maintenance burden; recommendation with decisive factor named
DORA metrics baseline Current values for all four metrics; gap to elite benchmark; prioritised improvement actions per metric; note which metrics are lagging indicators vs leading
Developer productivity measurement SPACE framework breakdown across all five dimensions; identify which dimensions are under-measured; propose lightweight instrumentation (build analytics, quarterly survey, friction log)
Deployment strategy selection Comparison table of Rolling / Blue-Green / Canary / Feature Flag against risk level, rollback speed, infra cost; recommendation with rollout plan
Internal documentation Runbook, contributing guide, or onboarding doc with: audience, prerequisites, step-by-step instructions, expected outcomes, troubleshooting section; reviewed against the standard that internal tools are products
Shift-left / pre-commit setup Map each check type to the correct stage (pre-commit / PR pipeline / post-merge) using the shift-left checklist; produce configuration for pre-commit hooks and CI workflow
Security in pipelines Secrets management approach (GitHub Secrets / Vault integration), dependency scanning config (Dependabot + Snyk/OWASP), SAST setup (CodeQL / SonarQube), pipeline-as-code review checklist
Flaky test remediation Quarantine strategy, root cause classification (timing / environment / data), fix approach per class, policy for blocking merge on flaky tests

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.

devex is a skill published in the GitHub repository pranav8494/team-of-agents (7 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 2,160 once invoked, about $0.0003 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.

Generate a Markdown handoff document summarizing the current conversation so another agent (Claude, Codex, opencode, pi, ampcode, Cursor, or a fresh session) can resume without re-deriving context. Produces docs/ -handoff.md. Invoke explicitly when a session is near its context limit.
