autospec-implementExecute the implementation plan by processing tasks defined in tasks.yaml.
Autospec Implement is an agent skill from ariel-frischer/autospec. Execute the implementation plan by processing tasks defined in tasks.yaml.
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Planning. The repository describes itself as: CLI for streamlined spec-driven development. The licence is MIT.
11 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 3381f26. 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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
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.
Autospec Implement loads about 3.6k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 1,376 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 patterns that need a careful read before installing.

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.

.claude/skills/autospec-implement/SKILL.md (or your agent's skills folder).This Agent Skill is generated from autospec.implement. When the user invokes "$autospec-implement" or "/autospec.implement", load and follow these instructions directly. Treat the text after the skill or command name as "$ARGUMENTS". Do not route back through "autospec implement"; this skill is the prompt for the stage.

$ARGUMENTSYou MUST consider the user input before proceeding (if not empty).
| Flag | Behavior |
|---|---|
--phase N | Execute ONLY phase N tasks. After completion, output "Phase N complete." and TERMINATE. Do NOT proceed to other phases. |
--context-file | Use bundled artifacts from context file. Do NOT separately read files listed in _context_meta.skip_reads. |
| (no flags) | Execute all phases sequentially. |
The following paths have been pre-computed and are available for use:
{{.FeatureDir}}{{.TasksFile}}{{if .ConstitutionFile}}{{.ConstitutionFile}}{{else}}not found{{end}}{{.IsGitRepo}}Phase Context Metadata (CRITICAL - Token Optimization):
Check if --context-file was used. If so, parse the _context_meta section FIRST before any other file reads.
_context_meta Fields:
phase_artifacts_bundled: true - Indicates that spec.yaml, plan.yaml, and tasks.yaml (phase-filtered) are already bundled in this context filebundled_artifacts - Lists the artifacts included, such as ["spec.yaml", "plan.yaml", "tasks.yaml (phase-filtered)", "constitution.yaml"]has_governance - Boolean indicating whether project governance is bundled in the governance: sectiontrue: Use the bundled governance: data as the constitution/governance source of truthfalse: No constitution was bundled; do not search for a governance file during context-file executiongovernance_file - Path to the constitution file when governance is bundledhas_checklists - Boolean indicating whether a checklists/ directory exists for this featurefalse: DO NOT check for, scan, or read from the checklists directory - it doesn't exist, skip step 3 entirelytrue: Checklists directory exists, proceed to step 3skip_reads - Explicit list of file paths that are already bundled and MUST NOT be read separatelyCRITICAL INSTRUCTION:
DO NOT read files listed in skip_reads when _context_meta.phase_artifacts_bundled is true.
DO NOT check for checklists directory when _context_meta.has_checklists is false.
DO NOT separately read _context_meta.governance_file when it appears in skip_reads; use the bundled governance section instead.Example _context_meta section:
_context_meta:
phase_artifacts_bundled: true
bundled_artifacts:
- spec.yaml
- plan.yaml
- tasks.yaml (phase-filtered)
- constitution.yaml
has_governance: true
governance_file: .autospec/constitution.yaml
has_checklists: false
skip_reads:
- specs/my-feature/spec.yaml
- specs/my-feature/plan.yaml
- specs/my-feature/tasks.yaml
- .autospec/constitution.yamlCheck checklists status (SKIP if _context_meta.has_checklists: false):
Scan all *.yaml checklist files in the checklists/ directory
For each checklist YAML file, parse and count:
categories[].items[])status: "pass"status: "fail" or status: "pending"Create a status table:
| Checklist | Total | Passed | Not Passed | Status |
|---------------|-------|--------|------------|--------|
| ux.yaml | 12 | 12 | 0 | PASS |
| api.yaml | 8 | 5 | 3 | FAIL |
| security.yaml | 6 | 6 | 0 | PASS |Calculate overall status:
status: "fail" or status: "pending"status: "pass"If any checklist is incomplete:
If all checklists are complete:
Load and analyze the implementation context (if NOT using --context-file):
Note: If you are using --context-file, the spec, plan, tasks, and possibly governance are already loaded from the context file. Skip reading files listed in _context_meta.skip_reads and use the bundled data from the spec:, plan:, tasks:, and governance: sections of the context file instead.
{{if .ConstitutionFile}}- REQUIRED GOVERNANCE: Read {{.ConstitutionFile}} for project principles, non-negotiable constraints, quality standards, and validation requirements before modifying code. Treat these governance rules as binding during implementation.{{else}}- GOVERNANCE: No constitution file was detected in a supported path. Continue using spec, plan, tasks, and local agent instructions.{{end}}

Progress tracking and task status updates:
CRITICAL: You MUST update task status in tasks.yaml as you work. This is non-negotiable.
Use the autospec update-task command to update task status:
autospec update-task <task_id> <status>When starting a task:
autospec update-task T001 InProgressWhen completing a task:
autospec update-task T001 CompletedIf a task is blocked:
autospec update-task T001 BlockedValid status values: Pending, InProgress, Completed, Blocked
Blocking tasks with reasons (preferred method for documenting blockers):
# Block a task and document why it's blocked
autospec task block T001 --reason "Waiting for API access from third-party team"
# Update the reason for an already blocked task
autospec task block T001 --reason "Updated: API approved, waiting for credentials"Unblocking tasks:
# Unblock a task (defaults to Pending status)
autospec task unblock T001
# Unblock and immediately set to InProgress
autospec task unblock T001 --status InProgressListing tasks by status:
# List all tasks
autospec task list
# List only blocked tasks (shows reasons)
autospec task list --blocked
# List pending tasks
autospec task list --pending
# List in-progress tasks
autospec task list --in-progress
# List completed tasks
autospec task list --completed
# Combine filters
autospec task list --blocked --pendingImplementation workflow for each task:

Execute the implementation plan by processing tasks defined in tasks.yaml. Autospec Implement is an agent skill from ariel-frischer/autospec.yaml.
Autospec Implement fits situations like: tasks that involve Planning.
Run `npx skills add ariel-frischer/autospec --skill autospec-implement -a claude-code`. Or copy the skill folder (.agents/skills/autospec-implement in ariel-frischer/autospec) into .claude/skills/autospec-implement in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ariel-frischer/autospec --skill autospec-implement -a codex`. Or copy the skill folder (.agents/skills/autospec-implement in ariel-frischer/autospec) into .agents/skills/autospec-implement 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 ariel-frischer/autospec --skill autospec-implement -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/autospec-implement, .gemini/skills/autospec-implement, .github/skills/autospec-implement and .opencode/skills/autospec-implement in your project.
SKILL.md names no scripts, command-line tools or credentials: Autospec Implement is instructions for the agent only. Our summary lists: Node.js; Docker.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md flagged 1 warning(s): mentions a credentials file (ssh keys, cloud or package-manager tokens). Read the flagged lines before installing; the check is not a guarantee either way.
Autospec Implement is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.6k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
