# Local Gradient > Evidence-led engineering studies on coding agents, software systems, > and local compute — published as a rich edition for people and an Open > Knowledge Format v0.2 bundle for tools, archives, and future models. Every folder with an index.md under /okf/ is itself a complete OKF bundle. ## Bundle - [OKF root index](https://localgradient.dev/okf/index.md): start here - [Full bundle zip](https://localgradient.dev/okf-bundle.zip) ## Posts - [Estimating agent work in agent time](https://localgradient.dev/okf/posts/estimating-agent-work-in-agent-time.md): A personal process for translating an agent-provided human-hour estimate into agent labor and wall-clock time using empirical calibration from completed traces. ## Skills - [Agent Effort Estimation](https://localgradient.dev/okf/resources/agent-effort-estimation/SKILL.md): Translate a coding agent's conventional human-hour estimate into agent labor and schedule wall-clock using empirical calibration from completed traces. Preserve the agent's task breakdown, range, assumptions, and dependencies; then apply declared parallelism. After shipping, compare with a look-back accounting pass so the conversion improves over time. - [Look Back Effort Accounting](https://localgradient.dev/okf/resources/look-back-effort-accounting/SKILL.md): Weigh completed agent-assisted software work after it ships. Produces an anonymized human-effort-equivalent activity measure, cleanup credit, attended wall-clock, agent labor when available, and calibration rows for later forecasts. Use for retrospective accounting, not prediction or valuation.
