What it does

Timeline Consolidator is an agent skill from SpecterOps/skills. Merge parsed timeline entries, apply MITRE tagging, and produce the final timeline outputs.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files and assets (for example `agents/openai.yaml`, `references/entry-schema.md` and `references/mitre-patterns.md`).

The repository describes itself as: A marketplace for LLM skills. The licence is Apache-2.0.

Example prompts

  • “/timeline-consolidator”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Load available entry files; skip missing ones but note their absence.
  2. Normalize each entry
  3. Apply MITRE ATT&CK tagging using pattern mappings (discovery, execution, lateral movement, persistence, etc.) and add mitre_tags array.
  4. Detect duplicates within a 5-second window per operator using textual similarity (SequenceMatcher). Flag duplicates with duplicate_flag…
  5. Merge entries, sort chronologically, and emit timeline table with columns (Timestamp, Source, Operator, MITRE, Action, Details).
  6. Store diagnostics (parsers processed, duplicates found, errors) in metadata for reporting.
  7. Preserve JSON-friendly raw_timestamp and source_file references for auditing.

What it can do on your machine

Read from SKILL.md and the folder at commit e655f93. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Timeline Consolidator loads about 456 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 28 tokens; SKILL.md has 191 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~456
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

Safety

Auto-check passed

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.

Timeline Consolidator

Use after parser skills to merge their JSON entries into the consolidated timeline.

Input Contract

  • JSON files in output/: cs_entries.json, mythic_entries.json, terminal_entries.json, md_notes_entries.json, pdf_notes_entries.json, gw_entries.json.

Output

  • output/timeline.md (markdown table) and output/timeline.json (normalized array) following the schema: timestamp, source, operator, action, details, mitre_tags, duplicate_flag, raw_timestamp.
  • Metadata report summarizing counts per source, duplications, and MITRE tag coverage.

Workflow

  1. Load available entry files; skip missing ones but note their absence.
  2. Normalize each entry:
    • Ensure timestamp is ISO 8601 UTC.
    • Guarantee source, operator, action, and details are filled.
  3. Apply MITRE ATT&CK tagging using pattern mappings (discovery, execution, lateral movement, persistence, etc.) and add mitre_tags array.
  4. Detect duplicates within a 5-second window per operator using textual similarity (SequenceMatcher). Flag duplicates with duplicate_flag and keep evidence of why flagged.
  5. Merge entries, sort chronologically, and emit timeline table with columns (Timestamp, Source, Operator, MITRE, Action, Details).
  6. Store diagnostics (parsers processed, duplicates found, errors) in metadata for reporting.
  7. Preserve JSON-friendly raw_timestamp and source_file references for auditing.

Notes

  • Document MITRE pattern definitions in references/mitre-patterns.md for future tuning.
  • Provide config knobs for duplicate detection window and similarity threshold (default 5s / 0.8 similarity).
