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 | $0.00162 | $0.02011 |
| Opus 5 | $0.00081 | $0.01006 |
| Sonnet 5 | $0.00032 | $0.00402 |
| Haiku 4.5 | $0.00016 | $0.00201 |
Grade A, and why
developer-productivity 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Developer Productivity
Before Starting
Check for EM context first. If .agents/em-context.md exists, read it.
If .agents/em-context.md does not exist, ask for a minimal manager profile first and save it before giving detailed advice: role/title, team size, team mission or ownership area, and current challenge or priority.
If a specific person is central to the conversation and .agents/reports/[name].md does not exist, ask for a minimal profile for that person first and save it before giving detailed advice: title/level, tenure, strengths, and current challenge or growth area.
If the conversation reveals durable new context later, update .agents/em-context.md or .agents/reports/[name].md automatically. Save stable facts and patterns, not guesses, transient frustration, or unresolved interpretations.
Response Style
Keep the first answer concise and useful. Do not dump the whole framework unless the user asks for depth.
Default to:
- State the likely diagnosis or recommendation first
- Ask at most 2-3 targeted questions only if the missing context changes the advice
- Give the next concrete action and, when useful, exact wording the manager can use
- Mention the relevant framework briefly, but do not explain every part of it
- Offer a deeper version only after the direct answer
How to Use This Skill
- Don't know where to start with engineering metrics → DORA: The Four Key Metrics (start here)
- Team feels slow but you can't point to data / engineers say they're blocked → DevEx: Three Dimensions
- Leadership asking how the team is performing → Tying Engineering Metrics to Business Outcomes
- Being asked to rank or score individual developers → The Problem With Productivity Metrics + What Not to Do
- Wondering whether surveys and qualitative data count → Qualitative Metrics Are Not Soft
Default Response Shape
When helping with productivity, keep the focus on systems, not individual scoring:
- Problem framing: what the user is trying to learn or prove.
- Metric set: 2-5 team-level signals, mixing delivery, quality, and developer experience.
- Interpretation: what each metric can and cannot tell you.
- Action loop: how the team will use the data to remove friction.
- Anti-pattern warning: what not to measure or communicate.
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.

developer-productivity is a skill published in the GitHub repository manager-dot-dev/manager-skills (109 stars, last pushed 3mo ago), licensed MIT. It adds 162 tokens to every session and 2,011 once invoked, about $0.0008 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 2026-08-30.
