Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `agents/openai.yaml` and `intent.json`).
The repository describes itself as: Intent-driven AI coding workflow runtime for consistent context, skills, approvals, validation, and handoffs across six AI coding hosts. The licence is AGPL-3.0.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 1dd4525. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Incremental Project Analysis loads about 2k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 597 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

V1 只读兼容:v1/<repoId>/snapshot.json 仅用于返回 compatibility-v1 + migrationRequired 导航信息,禁止作为 V2 reuse/accept 基线;下一次 bootstrap 必须走 full-required 并生成独立 V2 accepted snapshot。禁止迁移时原地改写 V1。

SemanticClaimV1,至少包含 type / statement / authority / sourceRange / rangeIdentity / sourceContentDigest / lensId / policyVersion / dependsOn / claimDigest / status。inventory-only 只能声明文件存在与内容身份;content-structured 只能声明文本中直接可解析的 heading、symbol、import、config/test 结构;只有 agent-semantic 可声明职责、风险或建议。status=accepted 声明;candidate/provisional/invalid 只能留在当轮候选输出,不得推进 runtime pointer。git diff --name-status,并用当前 digest 覆盖未提交/未跟踪/rename。fresh / stale / coverage-gap / incompatible / full-required。mtime/size 只能做候选加速;fresh 必须由 current bytes content identity 证明。rename 必须同时写旧 path tombstone 与新 path identity,delete 写 tombstone;配置变化保守扩到受影响全域。ImpactGraph 每条边必须含 type/source/evidenceStrength,图覆盖不足时不得声称 selective complete;unknownConsumerPaths 与 builder/stats 必须进入 graph identity。graph identity 变化会使未完成旧 plan 失效,但只在 builder 迁移或其他升级条件命中时触发全文;正常拓扑变化应以新图计算 changed/impact closure。
BatchProgressCard + 本批发现 + checkpoint + snapshot delta。accepted 批次继续;invalid/blocked 不得推进指针。复用抽样必须按 contentId/path 稳定排序选择 5%,最少 3、最多 20,不足 3 全抽。任一 content/fact mismatch 使本批 invalid + full-required;历史 runtime 只标 stale,不自动删除。
observe 与 bootstrap 的候选选择、结构提取、claimId、rangeDigest、Merkle root 和 sample 必须确定性;同一 repo/root、字节、环境身份与 lens 重跑必须得到相同 identity。持久化顺序为“先验证全部身份与任务证据,最后单次原子替换 runtime pointer”;任务证据写入失败时 pointer 不得推进。

Run `npx skills add devcodex-labs/devcodex --skill incremental-project-analysis -a claude-code`. Or copy the skill folder (content/skills/incremental-project-analysis in devcodex-labs/devcodex) into .claude/skills/incremental-project-analysis in your project. Claude Code loads it when a task matches its description.
Run `npx skills add devcodex-labs/devcodex --skill incremental-project-analysis -a codex`. Or copy the skill folder (content/skills/incremental-project-analysis in devcodex-labs/devcodex) into .agents/skills/incremental-project-analysis in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add devcodex-labs/devcodex --skill incremental-project-analysis -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/incremental-project-analysis, .gemini/skills/incremental-project-analysis, .github/skills/incremental-project-analysis and .opencode/skills/incremental-project-analysis in your project.
Going by SKILL.md and its folder, Incremental Project Analysis needs the command-line tools its instructions call (git).
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Incremental Project Analysis is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2k tokens (SKILL.md is roughly 8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Incremental Project Analysis: Implement Change (pnpm/pnpm, 37k stars), Incremental Implementation (addyosmani/agent-skills, 102k stars), Make Changes (remix-run/remix, 33k stars) and Orch Change Feature (affaan-m/ECC, 274k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
devcodex-labs (a GitHub organization) maintains it in devcodex-labs/devcodex, which has 439 GitHub stars. The repository holds 70 skills in this directory. The repository was last updated on September 17, 2026.
